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.

data, voice, and video services. The modular design of the Cisco 2800 series routers provides maximum

flexibility, allowing you to configure your router to meet evolving needs. The Cisco 2800 series routers

incorporate data, security, and voice services in a single system for fast, scalable delivery of crucial

business applications. The routers offer features such as hardware-based VPN encryption acceleration,

intrusion-protection and firewall functions, and optional integrated call processing and voice mail. The

routers offer a wide variety of network modules and interfaces, voice digital signal processor (DSP)

slots, high-density interfaces for a wide range of connectivity requirements, and sufficient performance

and slot density for future network expansion requirements and advanced applications.

The Cisco 2800 series consists of four versions. The Cisco 2801 routers and Cisco 2811 routers are one

rack unit in height and have two 10/100 LAN ports. The more powerful Cisco 2821 routers and

Cisco 2851 routers are two rack units in height and have two 10/100/1000 LAN ports. The higher-end

router platforms of the Cisco 2800 series offer increased performance, increased slot density including

network module slots ad extension voice module slots and increased inline power output.

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 40^oC. They operate at the highest speed in ambient temperatures above 40^oC.

The Cisco 2811 router has three fans that operate at a slower speed to conserve power and reduce fan

noise at ambient temperatures below 32^oC. They operate at high speed in ambient temperatures above

32^oC.

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 40^oC. They operate at high speed in ambient

temperatures above 40^oC.

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

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.

1. Interface abbreviations: fa = Fast Ethernet; gi = Gigabit Ethernet; usb = universal serial bus; bri = ISDN basic rate interface.

2. The interfaces listed are examples only; other possible interface types are not listed.

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.

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.
