930-watt AC Power Supply  
Power Supplies  
The Switch 4007 can contain two back-loading,  
Switch 4007 power supplies are autosensing. Each  
power supply (Figure 3) can automatically sense the  
type of input voltage to which it is being connected at  
the electrical outlet.  
930-watt, modular AC power supplies (Model  
Number 3CB9EP9). The power supplies provide  
power to the management modules, switch fabric  
module, interface modules, fans, and backplane.  
The power supplies are load sharing in that all power  
supplies provide an equal amount of the load current.  
Each 930-watt power supply has its own power cord  
and is shipped separately from the chassis. The type  
of power cord depends on your country location.  
Figure 3 shows a 930-watt AC power supply in a

for setting up your Switch 4007:  
There is at least 91.4 cm (36 in.) in back of the  
chassis to:  
Location Requirements  
Precautionary Guidelines  
Ventilation Requirements  
Power Requirements  
Safety Information  
Remove and replace power supplies.  
Maintain proper cooling.  
If the chassis is the first device in your rack, then  
mount it about 10.2 cm (4 in.) up from the floor.  
The power source is within approximately 2 meters  
(6.6 feet) of the location where you plan to install  
the Switch 4007.  
Location Requirements  
Install a Switch 4007 in an area that meets the  
following requirements:  
Each of the power supplies connects to a  
dedicated circuit. Do not connect the power  
supplies to a power strip.  
Ambient (room) temperature: 0 °C to 50 °C (32 °F  
to 122 °F). The default internal operating  
temperature threshold for the Switch 4007 is  
approximately 60 °C (140 °F).  
The surface on which you want to locate the  
Switch 4007 chassis is level.  
Have the required cables available at your site to  
make physical connections in your switch  
configuration.  
Relative humidity: between 10 and 90 percent,  
noncondensing.  
The table or rack on which you mount the chassis  
supports at least three times the weight of a fully  
loaded chassis.  
Precautionary Guidelines  
Ambient temperature for the Switch 4007 must  
not exceed 50 °C (122 °F).  
The recommended minimum space that is required  
between the front of the chassis and another  
vertical surface (such as a rack door) is 8 cm (3 in.).  
Safety regulations stipulate that for a Switch 4007  
chassis, the table, shelf, or rack on which the  
switch rests can support at least 115.65 kg (255  
lb), which is three times the weight of a fully  
loaded Switch 4007 chassis.  
There is a sufficient amount of space on each side  
of the Switch 4007 chassis to accommodate any  
cables along the side of the chassis.

Site Requirements for the Switch 4007  
31  
For rack installations, the selected rack is grounded  
in accordance with the rack manufacturers  
recommendations.  
To ensure that you tighten screws to Torque  
Specification, use a torque screwdriver.  
The following list shows the amount of rack space  
that is needed to install a Switch 4007 chassis in a  
Telco rack or a Metric rack.  
To reduce the possibility of personal injury or  
serious damage to the chassis, use  
at least two  
to install the chassis. This is especially  
people  
important for rack installations, because you must  
hold the chassis in place while you secure the  
chassis to the rack.  
Height — 30.98 cm / 12.2 in.  
The height of the chassis, allowing for some  
extension beyond the location of the upper and  
lower unit dividing lines.  
Bolt the rack to the floor.  
Make certain that the rack is properly aligned and  
squared. Use a framing tool to ensure that the rack  
is squared.  
Telco Rack Unit — 7 RU  
The unit of measure is 1 Rack Unit (1.75 in. or  
4.45 cm).  
Brace the top of the rack against the wall.  
Metric Rack Unit — 12.5 SU  
Provide sufficient space in front of and behind the  
chassis so that you can service it easily and provide  
proper ventilation.  
The unit of measure is 1 System Unit  
(25 millimeters).  
Front clearance — 8 cm / 3 in.  
Provide at least 7 cm (2.76 in.) on each side of  
the Switch 4007 chassis to ensure proper  
cooling in the chassis.  
This is the recommended minimum space required  
between the front of the chassis and another  
vertical surface (such as a rack door).  
Provide at least 91.4 cm (36 in.) in back of the  
switch to remove and replace power supplies in  
the Switch 4007 chassis.  
Rack-Mount Installation Recommendations  
Use at least two people to install any chassis.  
Use the following guidelines to tighten screws to  
Torque Specification:  
Before you install a chassis into a rack, make certain  
that the rack you are using is properly aligned and  
squared. Use a framing square to ensure that the rack  
is squared. Doing so makes installing the chassis into  
the rack easier.  
Faceplate thumbscrews — 3-5 in/lb  
(inch-pounds)  
#10 screws for holding the chassis onto the  
rail — 22-25 in/lb  
Power supplies to the chassis — 5-7 in/lb

The Switch 4007 supports a range of network  
management methods and contains an embedded  
Web-based management agent.  
The EME management module provides the following  
management and control capabilities:  
Configurations — When you are logged in using  
the Administer password, you can configure the  
management module and monitor the chassis  
environment.  
This chapter contains:  
EME Management Module Architecture  
Switch 4007 Setup Wizard  
Transcend Network Supervisor  
Web Management Tools  
Inventory — The management module provides a  
complete inventory of switch contents, including  
fans and power supplies. The inventory lists current  
software revisions for all installed modules. The  
inventory system also supports a scratchpad  
feature so that you can add custom information to  
the management module display.  
EME Management Module Architecture  
The Enterprise Management Engine (EME)  
management module is the primary communication  
mechanism into the chassis and any installed switch  
fabric modules and interface modules.  
SNMP Support — SNMP (Simple Network  
Management Protocol) is a protocol that the  
Internet Engineering Task Force defined. The  
management module acts as an agent in an  
SNMP-managed environment. The agent responds  
to SNMP requests and generates SNMP traps.  
The EME is an SNMP-based network management  
module that manages and controls the Switch 4007  
chassis and its modules.  
Telnet Support — With the management module  
telnet command, you can connect a  
management module to any other Telnet device.  
The management module also supports incoming  
Telnet sessions so that you can manage a  
management module from a workstation with  
Telnet support, or from another management  
module.

MAINTAINING THE SWITCH 4007  
6
This chapter describes the routine maintenance to  
perform to keep your Switch 4007 chassis working at  
its best. This chapter also provides instructions for  
replacing power supplies and fan trays.  
Routine Maintenance  
On a regular basis, inspect your Switch 4007 chassis  
to verify that all blank faceplates are securely attached  
to the chassis, and the fans are running.  
WARNING: Only trained electrical service personnel  
should perform switch connections and  
disconnections.  
CAUTION: The Switch 4007 sends a fan fault  
message when one fan fails in the fan tray. However,  
the switch can continue to run if one fan fails in the  
fan tray. If a second or third fan fails, in that fan tray,  
no trap message is generated. Replace the fan tray  
within 48 hours of receiving the trap message or  
contact your service representative.  
WARNING: Hazardous energy levels exist inside of  
the chassis. Do not place hands or objects into the  
switch or touch components on an inserted module.  
There are no user-serviceable parts on either the  
load-sharing power supplies or on the fan trays. If  
these components fail, remove them as described in  
this chapter and return them to your supplier. Keep  
replacement power supply units and fan trays at your  
site so that they are available if needed.  
Ventilation to the switch is unobstructed.  
All modules are securely seated in the backplane  
and firmly attached to the chassis.  
Module LEDs are functioning normally and show  
normal readings.  
This chapter provides information about the  
Switch 4007 chassis and contains the following  
topics:

Software-driven power management  
(Intelligent Power Management) also  
provides protection against the  
possibility of a catastrophic power  
failure. If the switch is operating in

power supply fails, an installed EME  
powers off selected (low power class)  
Switch 4007 modules until the power  
deficit is corrected. Intelligent Power  
Management ensures that key  
To support redundancy, install one or more power  
supplies beyond the minimum number that is  
required to support the chassis and its modules  
(n + 1 redundancy).  
Power Availability and Power Supply Capacity  
This section explains the following concepts  
concerning power supply management:  
components and resources continue to  
operate, even under extreme failure  
conditions.  
Power available to modules — The amount of  
power that is available to Switch 4007 modules is  
determined by the number of power supplies that  
are installed.  
Power capacity of a power supply — The  
power capacity of a power supply unit is the  
maximum amount of power that the power supply  
delivers.  
Power Management  
The Enterprise Management Engine (EME) works  
protects network integrity using power management.  
The EME determines how much power a Switch 4007  
module requires before it permits the module to  
power on.  
When you manage power in your Switch, consider  
the system overhead, that is, the power that the  
Switch 4007 itself (including fans, signalling, and  
EMEs) consumes. Before you install any new module  
into a chassis, assess the power budget by calculating  
the total power requirements for all installed  
modules, fans, and management modules.  
The EME manages power use in the chassis by:  
Preventing newly installed modules from receiving  
power when there is not enough power available.  
Allowing you to prioritize the order in which  
modules power off (if there is insufficient power  
available).

Power Management  
69  
See the documentation that is supplied with each  
module to determine your module power  
requirements. Take into account any modules that  
you plan to install, as well as those that are already  
installed.  
Rather, a factory-defined power limit (which is  
based on the number of installed power supplies)  
ensures that power that is equivalent to at least  
one power supply is available to replace power  
that is lost when a power supply fails.  
The amount of power that installed modules in a  
chassis require must not be greater than the  
Power Supply Modes  
number of installed power supplies, minus one  
(n-1). When you reserve power that is equivalent  
to one power supply in power fault-tolerant mode,  
the failure of a single power supply has no impact  
on installed modules that are already powered on.  
The Switch 4007 runs in either of two power supply  
modes:  
Fault-Tolerant Mode  
Non-Fault Tolerant Mode  
If a power supply fails while the switch is running in  
power fault-tolerant mode:  
For optimal power redundancy in either power mode,  
run the Switch 4007 with two power supplies.  
EMEs respond by automatically disabling power  
Fault-Tolerant Mode  
fault-tolerant mode.  
A user-selectable mode in which power that is  
equivalent to one power supply is held in reserve. This  
reserve power is not available to installed modules  
until a power supply fails, or until you switch the  
power mode from power fault-tolerant mode to  
power non-fault-tolerant mode.  
Power formerly reserved (unavailable to installed  
modules) is made available by power class and slot  
location to power-enabled Switch 4007 modules  
to prevent them from powering off (as an attempt  
to bring power consumption under the  
now-reduced power budget).  
All modules that had power before the power  
supply failure continue to receive power without  
interruption.  
While the chassis is running in fault-tolerant mode:  
All installed power supplies are functioning and  
contributing power to the chassis and modules.  
Upon power supply recovery, the EME  
automatically reenables power fault-tolerant  
mode.  
No single power supply is a dedicated standby  
power supply.

APPENDIX B: INTELLIGENT POWER SUBSYSTEM  
Operate the Switch 4007 in power fault-tolerant  
mode to ensure that power that is equivalent to at  
least one power supply is available to replace power  
that is lost if a single power supply fails.  
While the switch is running in power  
non-fault-tolerant mode, the amount of power that is  
available to modules is determined by the number  
and type of power supplies that are installed.  
To set the Switch 4007 to power fault-tolerant mode  
or to power non-fault-tolerant mode, enter the set  
power modecommand at the EME prompt.  
If a power supply fails while the chassis is running in  
power non-fault-tolerant mode:  
Installed management modules may shut down  
selected Switch 4007 interface modules and  
switch fabric modules in an attempt to bring  
installed module power consumption under the  
now-reduced power budget.  
When you attempt to set the Switch 4007 to power  
fault-tolerant mode, EMEs determine if there is  
sufficient unallocated power budget available to  
place power that is equivalent to one power supply in  
reserve.  
Installed interface modules and switch fabric  
modules continue to operate without interruption  
if the output of remaining installed power supplies  
is sufficient to provide adequate power to all  
installed modules.  
If there is sufficient unallocated power budget, the  
Switch 4007 sets to power fault-tolerant mode.  
If there is insufficient unallocated power budget,  
the Switch 4007 remains in power  
non-fault-tolerant mode.  
To prevent management modules from automatically  
disabling power fault-tolerant mode in response to a  
power supply failure, ensure that two power supplies  
are installed. If a power supply failure occurs under  
any condition, an alert is sent to the management  
application.  
Non-Fault Tolerant Mode  
A user-selectable mode in which 100 percent of the  
power that can be allocated to all modules is available  
to them (no power is held in reserve). This is the  
default mode for power supplies as shipped.
