Definitions of Service Request Severity  
To ensure that all service requests are reported in a standard format, Cisco has established severity  
definitions.  
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You  
and Cisco will commit all necessary resources around the clock to resolve the situation.  
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your  
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco  
will commit full-time resources during normal business hours to resolve the situation.  
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations  
remain functional. You and Cisco will commit resources during normal business hours to restore service  
to satisfactory levels.  
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or  
configuration. There is little or no effect on your business operations.

Hardware Features  
Removable and Interchangeable Modules  
Table 2 summarizes the optional modules that can be installed in the router to provide specific  
capabilities. The network modules, extension voice modules, and interface cards fit into slots, located  
on the front of the chassis on the Cisco 2801 router, and on the rear of the chassis on the Cisco 2811,  
Cisco 2821, and Cisco 2851 routers; they can be removed and installed without opening the chassis.  
Advanced integration modules (AIMs), expansion DRAM memory modules (DIMMs), and packet voice  
data modules (PVDMs) plug into connectors inside the chassis; they can be removed and installed only  
by opening the chassis.

Chassis Ventilation  
Internal multispeed fans provide chassis cooling, controlled by an onboard temperature sensor.  
The Cisco 2801 router has two fans. The Cisco 2801 router with inline power includes two additional  
fans integrated with the inline power supply, for a total of four fans. The Cisco 2801 internal fans operate  
at three different speeds, running at the slower speeds to conserve power and reduce fan noise at ambient  
temperatures below 40oC. They operate at the highest speed in ambient temperatures above 40oC.  
The Cisco 2811 router has three fans that operate at a slower speed to conserve power and reduce fan  
noise at ambient temperatures below 32oC. They operate at high speed in ambient temperatures above  
32oC.  
The Cisco 2821 and Cisco 2851 routers have three fans that operate at a slower speed to conserve power  
and reduce fan noise at ambient temperatures below 40oC. They operate at high speed in ambient  
temperatures above 40oC.  
Real-Time Clock  
An internal real-time clock with battery backup provides the system software with time of day on system  
power up. This allows the system to verify the validity of the certification authority (CA) certificate. In  
the Cisco 2811, Cisco 2821, and Cisco 2851 routers, the clock and battery are permanently installed; the  
battery lasts the life of the router under the operating environmental conditions specified for the router.  
The Cisco 2801 router has a socketed lithium battery. This battery lasts the life of the router under the  
operating environmental conditions specified for the router, and is not field-replaceable.  
Note  
If the lithium battery in a Cisco 2801 router should fail, the router must be returned to Cisco for repair.  
Although the battery is not intended to be field-replaceable, the following warning must be heeded:  
Warning  
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with  
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according  
to the manufacturer’s instructions. Statement 1015

Interface Numbering  
Table 7 summarizes the interface numbering on a Cisco 2801 series router. Table 8 summarizes the  
interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers.  
Note  
Note  
The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600  
series routers.  
On the Cisco 2801 router, the numbering format for slots is interface type 0/slot/port. “0” indicates slots  
that are built into the chassis of a router. On the Cisco 2801 router, all slots begin with “0,” because all  
slots are built into the chassis. Note that this is different from the Cisco 2811, Cisco 2821, and  
Cisco 2851 routers. On these routers, some slots are built into the chassis and have slot numbers that  
begin with “0”. However, it is possible to have other slots that are part of a network module or an  
extension voice module. Those slots have slot numbers that begin with “1” or “2,” respectively.

1. A VWIC in slots 1, 2, and 3 can operate in both data and voice mode; in slot 0, a VWIC can operate only in voice  
mode.  
Note  
On the Cisco 2801 router, the numbering format for configuring an asynchronous interface is 0/slot/port.  
To configure the line associated with an asynchronous interface, simply use the interface number to  
specify the async line. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0 on  
a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a  
WIC-2AM in slot 2.

3. Interface card slot numbers for double-width (HWIC-D) slots are 1 and 3 only.  
4. Specify the line number in the Cisco IOS CLI by using the interface number for the associated asynchronous serial interface.  
5. “1” is the network module slot number in all Cisco 2800 series routers.  
6. “2” is the EVM slot number in Cisco 2821 and Cisco 2851 routers.  
7. “0” is required by the CLI syntax for voice ports in an EVM; it indicates no interface card slots in EVMs.  
Note  
On the Cisco 2811, Cisco 2821, and Cisco 2851 routers, the interface numbering scheme is the same for  
asynchronous interfaces as other types of interfaces. To configure the line associated with an async  
interface, simply use the interface number to specify the async line. For example, line 0/3/0 specifies the  
line associated with interface serial 0/3/0 on a WIC-2A/S in slot 3. Similarly, line 1/22 specifies the line  
associated with interface async 1/22 on a NM-32A in network module slot 1.

Safety Recommendations  
Wear safety glasses when working under conditions that might be hazardous to your eyes.  
Do not perform any action that creates a hazard to people or makes the equipment unsafe.  
Safety with Electricity  
Warning  
Warning  
Warning  
This unit might have more than one power supply connection. All connections must be removed to  
de-energize the unit. Statement 1028  
Do not work on the system or connect or disconnect cables during periods of lightning activity.  
Statement 1001  
Read the installation instructions before connecting the system to the power source. Statement 1004  
Follow these guidelines when working on equipment powered by electricity:  
Locate the emergency power-off switch in the room in which you are working. Then, if an electrical  
accident occurs, you can quickly turn off the power.  
Disconnect all power before doing the following:  
Installing or removing a chassis  
Working near power supplies  
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power  
extension cables, frayed power cords, and missing safety grounds.  
Do not work alone if hazardous conditions exist.  
Never assume that power is disconnected from a circuit. Always check.  
Never open the enclosure of the router’s internal power supply.  
If an electrical accident occurs, proceed as follows:  
Use caution; do not become a victim yourself.  
Turn off power to the device.  
If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and  
then call for help.  
Determine if the person needs rescue breathing or external cardiac compressions; then take  
appropriate action.  
In addition, use the following guidelines when working with any equipment that is disconnected from a  
power source, but still connected to telephone wiring or other network cabling:  
Never install telephone wiring during a lightning storm.  
Never install telephone jacks in wet locations unless the jack is specifically designed for it.  
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at  
the network interface.  
Use caution when installing or modifying telephone lines.

General Site Requirements  
Preventing Electrostatic Discharge Damage  
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if  
electronic printed circuit cards are improperly handled and can cause complete or intermittent failures.  
Always follow ESD prevention procedures when removing and replacing modules:  
Ensure that the router chassis is electrically connected to earth ground.  
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to  
an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To  
guard against ESD damage and shocks, the wrist strap and cord must operate effectively.  
If no wrist strap is available, ground yourself by touching a metal part of the chassis.  
Caution  
For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should  
be between 1 and 10 megohms (Mohm).  
General Site Requirements  
This section describes the requirements your site must meet for safe installation and operation of your  
router. Ensure that the site is properly prepared before beginning installation. If you are experiencing  
shutdowns or unusually high errors with your existing equipment, this section can also help you isolate  
the cause of failures and prevent future problems.  
Power Supply Considerations  
Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise).  
Install a power conditioner if necessary.  
Warning  
The device is designed for connection to TN and IT power systems. Statement 1007  
The AC power supply includes the following features:  
Autoselects either 110 V or 220 V operation.  
All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates  
the correct voltage, frequency [AC-powered systems only], current draw, and power dissipation for  
the unit.)

Site Environment  
Cisco 2800 series routers can be placed on a desktop or installed in a rack. This Cisco 2811 router can  
also be wall mounted. The location of your router and the layout of your equipment rack or wiring room  
are extremely important considerations for proper operation. Equipment placed too close together,  
inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make  
maintenance difficult. Plan for access to both front and rear panels of the router.  
When planning your site layout and equipment locations, remember the precautions described in the next  
section “Site Configuration,” to help avoid equipment failures and reduce the possibility of  
environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high  
number of errors with your existing equipment, these precautions may help you isolate the cause of the  
failures and prevent future problems.

General Site Requirements  
Site Configuration  
The following precautions will help you plan an acceptable operating environment for your router and  
will help you avoid environmentally caused equipment failures:  
Ensure that the room where your router operates has adequate air circulation. Electrical equipment  
generates heat. Without adequate air circulation, ambient air temperature may not cool equipment  
to acceptable operating temperatures.  
Always follow ESD-prevention procedures described in the “Preventing Electrostatic Discharge  
Damage” section on page 3 to avoid damage to equipment. Damage from static discharge can cause  
immediate or intermittent equipment failure.  
Ensure that the chassis cover and module rear panels are secure. All empty network module slots,  
interface card slots, and power supply bays must have filler panels installed. The chassis is designed  
to allow cooling air to flow within it, through specially designed cooling slots. A chassis with  
uncovered openings permits air leaks, which may interrupt and reduce the flow of air across internal  
components.  
Equipment Racks  
Cisco 2800 series routers include brackets for use with a 19-inch rack or, if specified in your order,  
optional larger brackets for use with a 23-inch rack.  
Note  
Brackets for a 23-inch rack are not available for Cisco 2801 routers.  
The following information will help you plan your equipment rack configuration:  
Allow clearance around the rack for maintenance.  
Allow at least one rack unit of vertical space between routers.  
Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each  
router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.  
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports  
of the equipment above.  
When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or  
exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated  
into the rack.  
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through  
the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can  
be found by experimenting with different configurations.  
When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the  
equipment by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to  
allow the router under test a maximum of cooling air and clean power.

Port and Cable Information for Cisco 2800 Series  
Routers  
This document provides information about cables needed to install your Cisco 2800 series integrated  
services router. It includes the following sections:  
Console and Auxiliary Port Considerations  
The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary  
ports provide access to the router either locally using a console terminal connected to the console port,  
or remotely using a modem connected to the auxiliary port. This section discusses important cabling  
information to consider before connecting the router to a console terminal or modem.  
The main difference between the console and auxiliary ports is that the auxiliary port supports hardware  
flow control and the console port does not. Flow control paces the transmission of data between a  
sending device and a receiving device. Flow control ensures that the receiving device can absorb the data  
sent to it before the sending device sends more. When the buffers on the receiving device are full, a  
message is sent to the sending device to suspend transmission until the data in the buffers has been  
processed. Because the auxiliary port supports flow control, it is ideally suited for use with the  
high-speed transmissions of a modem. Console terminals send data at slower speeds than modems;  
therefore, the console port is ideally suited for use with console terminals.  
Console Port Connections  
The router has an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and  
the adapter used, this port appears as a DTE or DCE device at the end of the cable.  
For connection to a PC running terminal emulation software, your router is provided with an RJ-45 to  
DB-9 adapter cable.  
To connect the router to an ASCII terminal, use the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter  
(provided with the Cisco 2801 router only).

Preparing to Connect to a Network  
The default parameters for the console port are 9600 baud, 8 data bits, 1 stop bit, and no parity. The  
console port does not support hardware flow control. For detailed information about installing a console  
For cable and port pinouts, refer to the online document Cisco Modular Access Router Cable  
Specifications. This document is located on Cisco.com.  
Auxiliary Port Connections  
The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control.  
Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the  
cable.  
For connection to a modem, your router is provided with an RJ-45-to-DB-25 adapter cable. (A  
DB-9-to-DB-25 adapter is also included with the Cisco 2801 router.)  
For detailed information about connecting devices to the auxiliary port, see the “Connecting to a Console  
Routers” online document.  
For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications online  
document on Cisco.com.  
Preparing to Connect to a Network  
When setting up your router, consider distance limitations and potential electromagnetic interference  
(EMI) as defined by the applicable local and international regulations.  
Network connection considerations are provided for several types of network interfaces and are  
described in the following sections:  
Refer to the following online documents for more information about network connections and interfaces:  
Warning  
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network  
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some  
LAN and WAN ports both use RJ-45 connectors. Statement 1021

Preparing to Connect to a Network  
Ethernet Connections  
The IEEE has established Ethernet as standard IEEE 802.3. Cisco 2800 series routers support the  
following Ethernet implementations:  
1000BASE-T—1000 Mbps full-duplex transmission over a Category 5 or better unshielded  
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).  
Note  
The Cisco 2801 and Cisco 2811 routers do not support the 1000BASE-T Ethernet  
implementation.  
100BASE-T—100 Mbps full-duplex transmission over a Category 5 or better unshielded  
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).  
10BASE-T—10 Mbps full-duplex transmission over a Category 5 or better unshielded twisted-pair  
(UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).  
Refer to the Cisco Modular Access Router Cable Specifications online document for information about  
Ethernet cables, connectors, and pinouts.  
Serial Connections  
Serial connections are provided by WAN interface cards and network modules. For more information on  
WAN interface cards, refer to the Cisco Interface Cards Installation Guide. For more information on  
network modules, refer to the Cisco Network Modules Hardware Installation Guide. These documents  
are accessible online at Cisco.com.  
Before you connect a device to a serial port, you need to know the following:  
Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are  
connecting to the synchronous serial interface  
Type of connector, male or female, required to connect to the device  
Signaling standard required by the device  
Configuring Serial Connections  
The serial ports on the asynchronous/synchronous serial network modules and the serial WAN interface  
card use DB-60 connectors. Serial ports can be configured as DTE or DCE, depending on the serial cable  
used.  
Serial DTE or DCE Devices  
A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE  
device provides a clock signal that paces the communications between the device and the router. A DTE  
device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation  
that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a  
jumper to select either DTE or DCE mode.) Table 1 lists typical DTE and DCE devices.

1. If pins protrude from the base of the connector, the connector is male.  
2. If the connector has holes to accept pins, the connector is female.  
Signaling Standards Supported  
The synchronous serial ports available for the router support the following signaling standards:  
EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco DB-60 shielded serial  
transition cable that has the appropriate connector for the standard you specify. The documentation for  
the device you want to connect should indicate the standard used for that device. The router end of the  
shielded serial transition cable has a DB-60 connector, which connects to the DB-60 port on a serial  
WAN interface card. The other end of the serial transition cable is available with a connector appropriate  
for the standard you specify.  
The synchronous serial port can be configured as DTE or DCE, depending on the attached cable (except  
EIA-530, which is DTE only). To order a shielded cable, contact customer service. See the “Obtaining  
Technical Assistance” section of the “” online document.  
Note  
All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device.  
Although manufacturing your own serial cables is not recommended (because of the small size of the  
pins on the DB-60 serial connector), cable pinouts are provided in the Cisco Modular Access Router  
Distance Limitations  
Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the  
greater the distance. All serial signals are subject to distance limits, beyond which a signal significantly  
degrades or is completely lost.  
Note  
Only the serial WAN interface card supports bit rates above 128 Kbps.  
Table 2 lists the recommended maximum speeds and distances for each serial interface type; however,  
you might get good results at speeds and distances greater than those listed, if you understand the  
electrical problems that might arise and can compensate for them. For instance, the recommended  
maximum rate for V.35 is 2 Mbps, but 4 Mbps is commonly used.

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232 signals. The  
recommended distance limits for EIA/TIA-449 shown in Table 2 are also valid for V.35, X.21, and  
EIA-530. Typically, EIA/TIA-449 and EIA-530 can support 2-Mbps rates, and V.35 can support 4-Mbps  
rates.  
Asynchronous/Synchronous Serial Module Baud Rates  
The following baud-rate limitations apply to the slow-speed serial interfaces found in the  
asynchronous/synchronous serial modules:  
Asynchronous interface—Maximum baud rate is 115.2 kbps.  
Synchronous interface—Maximum baud rate is 128-kbps full duplex.  
ISDN BRI Connections  
The BRI WAN interface cards provide Integrated Services Digital Network (ISDN) Basic Rate Interface  
(BRI) connections. The BRI modules and BRI WAN interface cards are available with either an S/T  
interface that requires an external Network Terminator 1 (NT1), or a U interface that has a built-in NT1.  
You can install the BRI modules in any available slot in the chassis.  
Warning  
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF  
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,  
detach the end away from the unit first. Statement 1026  
Use a BRI cable (not included) to connect the BRI WAN interface card directly to an ISDN. Table 3 lists  
the specifications for ISDN BRI cables. Also, refer to the Cisco Modular Access Router Cable  
Specifications online document for pinouts. This document is located on Cisco.com.

Setting Up the Chassis  
For Installing CompactFlash Memory Cards  
Note  
If there are internal FRUs to be removed or installed, perform the installation or removal before you  
install the chassis in a rack on a wall. To remove internal FRUs, you have to remove the chassis cover;  
this requires removal of the chassis from the rack.  
If the required internal FRUs are already installed, proceed to the next section, “Setting Up the Chassis”.  
Setting Up the Chassis  
Note  
Cisco 2800 series routers are normally ordered with modules and interface cards preinstalled. Before you  
remove or install any modules or interface cards, see the documents that accompany those items or to  
the online Cisco 2800 series hardware installation documentation at the following URL:  
For module and interface card compatibility information, see the data sheet for each module and  
interface card.  
Warning  
Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.  
Statement 1  
You can set any Cisco 2800 series router on a desktop or install it in a rack. A Cisco 2811 router can also  
be mounted on a wall or other flat surface. See the applicable instructions in the following sections.  
Caution  
To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front.  
Always hold the chassis by the metal body.  
Rack-Mounting the Chassis  
If you are planning to rack-mount the router, do so before making network and power connections. If  
you need to install network modules or interface cards, you can do so either before or after  
rack-mounting the router. Ideally, you would install modules and interface cards when you have the best  
access to the rear panel of the router. Internal modules, such as advanced integration modules (AIMs) or  
packet voice data modules (PVDMs), should be installed prior to rack-mounting.

Setting Up the Chassis  
Cisco 2811, Cisco 2821, and Cisco 2851 routers can be installed in 19 (48.26-cm)- and 23-inch  
(58.42-cm) racks. Cisco 2801 routers can be installed only in 19-inch racks, and cannot be center  
mounted. Use the standard brackets shipped with the router for mounting the chassis in a 19-inch rack;  
you can order optional larger brackets for mounting the chassis in a 23-inch rack.  
Note  
Brackets for 23-inch (58.42-cm) equipment racks are not available for Cisco 2801 routers.  
You can mount the router in the following ways:  
Center mounting—Brackets attached in the center of the chassis with only the front panel facing  
forward. (This option is not available on Cisco 2801 routers.)  
Front mounting—Brackets attached at the front of the chassis with the front panel facing forward.  
Rear mounting—Brackets attached at the rear of the chassis with the rear panel facing forward.  
The brackets are shown in Figure 5, Figure 6, and Figure 7.

Wiring Procedure for DC Input  
To connect a router to a DC power source, perform the following steps:  
Step 1  
Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the  
circuit breaker for the DC circuit, switch the circuit breaker to the OFF position, and tape the  
circuit-breaker switch in the OFF position.  
Warning  
Before performing any of the following procedures, ensure that power is removed from the DC circuit.  
Statement 1003  
Tip  
Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.  
Warning  
When stranded wiring is required, use approved wiring terminations, such as closed-loop or  
spade-type with upturned lugs. These terminations should be the appropriate size for the wires and  
should clamp both the insulation and conductor. Statement 1002  
Step 2  
Strip the wires to the appropriate length for the terminals. The strip length is 3/16 to 1/4 inch (5 to 6 mm)  
for Amp/Tyco No. 32957 terminals.  
Step 3  
Step 4  
Crimp the terminals to the power input and safety ground wires.  
Remove the plastic covers from the terminal block. Save the covers for reinstallation after you finish  
wiring.  
Step 5  
Connect the wires to the terminal block, starting with the safety ground wire. Connect each wire to the  
appropriate terminal as shown in Figure 1. Tighten the terminal screws to 8.0 0.5 in-lb  
(0.9 0.05 N-m).  
Warning  
The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated.  
The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The  
ground wire should always be connected first and disconnected last. Statement 239  
Warning  
Caution  
An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure  
that no exposed portion of the DC-input power source wire extends from the terminal block plug.  
Statement 122  
Do not overtorque the terminal block contact screws. Recommended torque is 8.0 0.5 in-lb  
(0.90 0.05 N-m).

In Figure 6, source A and source B share common positive terminal connections. This is allowed only if  
Va equals Vb (within 0.25 V).  
Caution  
When connecting source A and source B with common positive terminals, if source A and source B  
voltages are unequal by more than 0.25 V, the higher-voltage source can discharge into the lower-voltage  
source through the A- and B- input terminals. Excessive discharging currents through these terminals  
can cause one or both of the dual input DC power supply's internal A- or B- fuses to open, resulting in  
lack of redundancy or system failure. When source A and source B are within 0.25 V, discharge current  
is minimal.  
Note  
When source A and source B are wired with common negative terminals, as in Figure 5, discharging does  
not occur and there is no restriction requiring that source A and source B voltages be equal.

Connection Procedures and Precautions  
Connect each WAN, LAN, and voice cable to the appropriate connector on the chassis or on a network  
module or interface card.  
Position the cables carefully, so that they do not put strain on the connectors.  
Organize cables in bundles so that cables do not intertwine.  
Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition cables,  
if necessary.  
Install cable ties in accordance with site requirements.  
For cable pinouts, refer to the Cisco Modular Access Router Cable Specifications document.  
Connecting to a Console Terminal or Modem  
Your router has asynchronous serial console and auxiliary ports for system management. These ports  
provide administrative access to your router either locally (with a console terminal or PC) or remotely  
(with a modem).  
Cisco provides the following cables for connecting your router to a console terminal, PC, or modem:  
One console cable (RJ-45-to-DB-9, blue)  
One modem cable (RJ-45-to-DB-25, black) (Cisco 2811, Cisco 2821, and Cisco 2851 only)  
One DB-9-to-DB-25 adapter (Cisco 2801 only)  
This section describes how to connect a console terminal or PC to the console port and how to connect  
a modem to the auxiliary port. Table 4 summarizes the system management connections.

Solving Problems  
Solving Problems  
The key to solving problems is to isolate the problem to a specific subsystem by comparing what the  
router is doing to what it should be doing.  
The LEDs on the front and rear panel of the router enable you to determine router performance and  
operation. LEDs are described in the following sections:  
When solving problems, consider the following router subsystems:  
Power and cooling systems—External power source, power cable, router power supply and circuit  
breaker, and router blower and fan. Also consider inadequate ventilation or air circulation.  
Modules—LEDs on the modules help identify a failure.  
Cables—External cables that connect the router to the network.  
Troubleshooting the Power and Cooling Systems  
Both the system LED and the fans can help you troubleshoot a power problem. Check the following  
items to help isolate the problem:  
Normal Indications  
With the power switch on, the normal indications are:  
SYS PWR LED on green and continuous  
Fans operating  
AUX/PWR LED on green and continuous, if the IP phone power module or Cisco Redundant Power  
Supply (RPS) is installed  
Fault Indications  
Check the following symptoms to locate or eliminate faults in the power and cooling systems:  
With the power switch on, is the SYS PWR LED on?  
If the LED is green and continuous, the router is receiving power and is functional.  
If the LED is amber, the router is receiving power but is not functional.  
If the LED is off, check the power source and power cable.  
With the power switch on and the SYS PWR LED on and green, do the fans operate?  
If no, check the fans.  
If yes, the power system is functioning.  
With the power switch on and the PWR SYS LED off, do the fans operate?  
If yes, the router is receiving power. The fans are connected directly to the DC outputs of the  
power supply.  
If no, check the power source and power cable.

Installing Slot Dividers in Network Module Slots  
Installing Slot Dividers in Network Module Slots  
In a Cisco 2851 router, you can install a slot divider in the network module slot to reduce the slot width  
from extended double-wide to extended single-wide. Use of a slot divider alone (without a filler panel)  
creates a slot width suitable for an enhanced extended single-wide (NME-X) network module. Use of a  
slot divider with a filler panel creates a slot width suitable for an enhanced single-wide (NME) or older  
version (NM) single-wide network module.  
Figure 1 shows a slot divider with captive screw for the network module slot in Cisco 2851 routers.  
Figure 1  
Slot Divider for Network Module Slots  
Install slot dividers into network module slots as follows:  
Step 1  
Insert the top rails of the slot divider between the two guide rails in the top of the network module slot.  
See Figure 2.

Installing and Removing Filler Panels in Network Module Slots  
Installing and Removing Filler Panels in Network Module Slots  
You can install filler panels in extended-wide network module slots to reduce the slot width. Use one  
filler panel to reduce an extended single-wide slot (NME-X) to standard single-wide (NME). Use two  
filler panels to reduce an extended double-wide slot (NME-XD) to standard double-wide (NMD).  
Figure 5 shows a filler panel for network module slots.  
Figure 5  
Filler Panel for Network Module Slots  
You can use filler panels in the following configurations:  
In a Cisco 2821 router, use one filler panel to reduce the extended single-wide slot (NME-X) to  
standard single-wide slot (NME).  
In a Cisco 2851 router, use filler panels as follows:  
To create a slot for a standard double-wide network module (NMD), use two filler panels at the  
far right. See Figure 6.  
To create a slot for an extended single-wide network module (NME-X), use one filler panel at  
the far right, a slot divider in the middle, and a blank panel at the right. See Figure 7.  
To create a slot for a standard single-wide network module (NME or NM), use one filler panel  
at the far right, a slot divider in the middle, a blank panel at the right, and a filler panel next to  
the slot divider. See Figure 8.

Installing and Removing PVDMs  
Cisco 2801 and Cisco 2811 routers hold up to two Cisco packet voice data modules, version 2 (PVDM2)  
to support enhanced versions of digital signal processors (DSPs). Cisco 2821 and Cisco 2851 routers  
hold up to three PVDM-IIs. If only one is PVDM installed, it must be located in the PVDM 0 connector.  
Before you remove or install a PVDM, remove the chassis cover as described in the “Removing the  
Note  
PVDM-II connectors in the Cisco 2800 series routers are not compatible with older PVDM versions.  
Caution  
When you remove or install PVDMs, always wear an ESD-preventive wrist strap, and ensure that it  
makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the  
chassis.  
Caution  
Handle PVDMs by the edges only. PVDMs are ESD-sensitive components and can be damaged by  
mishandling.

Replacing the Power Supply  
Removing the Existing Power Supply  
To remove a power supply from a Cisco 2811 router, perform the following steps.  
Caution  
Step 1  
Do not disconnect the flat ribbon cable (shown in Figure 33). The cable is of adequate length to perform  
the power supply replacement procedure. Removing the flat ribbon cable without the proper tools may  
cause damage to components in the router.  
Disconnect the power output cable connector (or connectors—see note below) from the power supply.  
Power supply connectors have a locking feature on the power supply end that you must release. Do not  
disconnect any power cables from the system board.  
Note  
The AC-input power supply in a Cisco 2811 router uses only one power output cable. The  
DC-input power supply and the ILP supply each use two power output cables that must be  
disconnected. On the ILP supply, the ILP cable is also hooked to cable guides on the power  
supply and the chassis, so it must be both disconnected and unhooked from the power supply.  
See Figure 40.  
Step 2  
Remove the air duct by squeezing it gently at the bottom and lifting it straight up. See Figure 33. Note  
that there are four snaps on the air duct, two on each side. By squeezing the air duct, the snaps are  
released from the sheet metal retainers in the chassis that capture them.

Removing and Installing CompactFlash Memory  
Cards in Cisco 2800 Series Routers  
This document describes installing and replacing CompactFlash memory cards in Cisco 2800 series  
integrated services routers. It contains the following sections:  
Preventing Electrostatic Discharge Damage  
CompactFlash memory cards are sensitive to electrostatic discharge (ESD) damage, which can occur  
when electronic cards or components are handled improperly, results in complete or intermittent failures.  
To prevent ESD damage, follow these guidelines:  
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.  
Connect the equipment end of the strap to an unfinished chassis surface.  
Place a removed CompactFlash memory card on an antistatic surface or in a static shielding bag. If  
the card will be returned to the factory, immediately place it in a static shielding bag.  
Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages  
on the body only; ESD voltages on clothing can still cause damage.  
Do not remove the wrist strap until the installation is complete.  
Caution  
For safety, periodically check the resistance value of the antistatic strap. The measurement should be  
between 1 and 10 megohms (Mohms).  
Removing a CompactFlash Memory Card  
To remove a CompactFlash memory card from the chassis, perform the following steps (see Figure 1):

Installing a CompactFlash Memory Card  
Caution  
Step 1  
Do not remove a CompactFlash memory card from the chassis while it is being accessed. The CF LED  
blinks to indicate when flash memory is being accessed. Removing the CompactFlash memory card from  
the router while flash memory is being accessed can cause damage to your router.  
Press the ejector button next to the CompactFlash memory card. The ejector button moves outward so  
that it projects from the panel.  
Step 2  
Step 3  
Step 4  
Press the ejector button again. This ejects the CompactFlash memory card part-way out of its slot.  
Pull the CompactFlash memory card out of its slot.  
Push the ejector button in until the button is flush with the bezel.  
Caution  
To prevent damage to the ejector mechanism, the ejector button must remain pressed all the way in (flush  
against the bezel) when not being used to eject a CompactFlash memory card.

Note  
If the ejector button is projecting out from the panel, push it in until it is flush with the bezel.  
Step 2  
Insert the CompactFlash memory card into the slot until it is fully seated. The ejector button remains  
flush with the panel.  
Note  
If the ejector button is projecting from the panel after you insert the CompactFlash memory card,  
remove the CompactFlash memory card, press the ejector button until it clicks, and reinsert the  
CompactFlash memory card.
