Maintaining the Cisco 10005 ESR
The Cisco 10005 ESR is configured to your order and ready for installation when
it arrives. After you install the system, you may have to perform specific
maintenance procedures to ensure the router operates properly. These routine
procedures include replacing the filter, upgrading system components, or
replacing field replaceable units (FRUs). This chapter contains the information
necessary to perform that maintenance for the Cisco 10005 ESR.
Note Detailed instructions are also shipped with FRUs and upgrade kits.
System components fall into two categories: hot swappable components that do
not require you to power off the system before replacing them, and those
components that do require you to power off the system before you replace them.
For example, all line cards are hot-swappable and can be replaced without
powering off the system, but you must power off the system before replacing a
single power module or a single Performance Routing Engine (PRE).
Note To prevent alarms from activating, you must administratively shut down a line
card before hot swapping it.

Spare Parts
Service providers usually draw on their own experience with similar equipment
as they try to determine the number of spare parts of a given item to keep on hand.
In developing a strategy for spare parts, the service providers must
•Evaluate the criticality of the equipment.
•Estimate the mean time between failures, a key component of any spares
strategy.
•Calculate the number of production routers (and associated components) they
need to have on hand. For example, if they have the critical mass to shift
capacity to other locations or other devices, they may be able to carry fewer
spares.
Service providers may also subscribe to services that supply them with
replacement parts, sometimes with turnaround times as short as 4 hours.

Chapter 3 Maintaining the Cisco 10005 ESR
Redundancy
Service providers trying to decide on the level of redundancy appropriate for their
operations must examine their business models. The service provider invests more
heavily in high network reliability if the business model
•Calls for protected services
•Provides customer service-level agreements
•Accommodates customers that require a high degree of reliability
•Emphasizes overall reliability as opposed to cost
In addition, the service provider discusses the situation with the supplier to
identify those software and hardware features likely to experience the most stress
and thus to have the shortest mean time between failures. The point is to
determine, not just whether or not redundancy is to be used, but also the quantity
to be used (1:1, 2:1, or greater).
Some service providers have redundant chassis, but not redundant routing
engines. This approach gives them increased flexibility, so that they can provide
reliable service and accommodate a growing number of customers. Customers
requiring the highest levels of network reliability and availability often add
redundancy by connecting to two different service providers.

Required Maintenance Tools
The tools required to perform the maintenance procedures described in this
chapter are:
•A Number 2 Phillips screwdriver
•A flat-blade screwdriver
•An electrostatic discharge (ESD) grounding strap
Backing Up the PCMCIA Flash Memory Card
Cisco recommends that you create a duplicate PCMCIA card that contains the
current boot software image and the current software configuration. You can use
the backup card to quickly recover from a major system failure. You can also use
a backup card to load a new PRE module and avoid the time-consuming
reconfiguration process. For instructions to create a backup PCMCIA card, refer
to the Cisco 10000 Series ESR Software Configuration Guide.
Formatting Flash Memory Cards and Disks
The Flash memory disk card that shipped with your router contains the default
Cisco IOS image for booting your router. This section explains how to format an
ATA f l a s h d i s k .
Caution The formatting procedure erases all information on Flash memory disks or cards.
Flash memory ATA disks and Flash memory cards use similar commands. The
primary syntax change is that disk0: or disk1: refers to Flash memory ATA disks
while slot0: or slot1: refers to Flash memory cards.
To format a Flash memory disk:
Step 1 Ensure there is a Flash memory disk in PCMCIA slot 0 or slot 1 of the PRE.
Step 2 To format the disk, enter the format diskn:command at the privileged EXEC
mode prompt.

Shutting Down the System
The following example shows the expected output after you enter the format
disk0: command:
Router# format disk0:
All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): MyNewdisk
Formatting sector 1
Format device slot0 completed
Router#
The Flash memory disk is now ready for use.
Shutting Down the System
Although most components in the Cisco 10005 ESR are hot-swappable, you
might have to shut down the system under certain circumstances—for example, if
you are replacing the only power module or the only PRE in a nonredundant
system.
To shut down the system:
Step 1 Notify appropriate personnel that you plan to shut down the system and that a
shutdown results in loss of service. Appropriate personnel includes the regional
alarm or network monitoring center, central office personnel, and customers.
Step 2 Before you shut down the router, use the copy command to save any configuration
changes to NVRAM, and also, if you wish, to a PCMCIA Flash card. (See the
Cisco 10000 Series ESR Software Configuration Guide for instructions about
using the copy command.)
Step 3 Power down the system by setting the switches on all power modules to the 0 (off)
or standby position. (Your system can have one or two power modules.)
Warning Before you work on a system that has a standby/off switch, turn off the power
by pressing the power switch to standby and unplugging the power cord.

Removing and Replacing Field-Replaceable Units
This section contains procedures to remove and replace all of the field replaceable
units (FRUs) for the Cisco 10005 ESR.
Replacing the Air Filter
If the air filter is dirty or clogged, the fan assembly might not be able to provide
sufficient cooling air flow through the chassis, causing the system to overheat. To
prevent an overheating problem, replace the air filter every 6 months. In dirty or
dusty environments, replace the filter more frequently.
Note If you want to reuse the air filter, use a vacuum cleaner to remove the dust.
The air filter is accessible from the rear of the chassis. It occupies a vertical slot
on the left side of the chassis.
To replace the air filter:
Step 1 Use a flat blade screwdriver to turn the cam fastener on the air filter cover one half
of a rotation (180 degrees) (Figure 3-1).

Removing and Replacing Field-Replaceable Units
Step 5 To replace the filter cover, insert the tab on the bottom of the cover into the slot at
the bottom of the air filter compartment. Pivot the cover up into place.
Step 6 Turn the cam fastener ½ of a rotation (180 degrees) to secure the filter to the
chassis.
Replacing the Fan Assembly
The fan assembly supports hot-swapping (for up to 2 minutes) and can be replaced
without interruption to system operation.
The fan assembly is accessible from the rear of the chassis. It occupies a vertical
slot on the right side of the unit.
Caution To prevent the system from overheating, be sure that the replacement fan
assembly is out of its box and packaging, so it is ready to install as soon as the
defective module is removed.
To replace the fan assembly:
Step 1 Move any interface cables away from the fan assembly.
Step 2 Loosen the captive screw on the fan assembly and slide the assembly out of the
chassis (Figure 3-4).
Warning The fans might still be turning when you remove the fan assembly from the
chassis. Keep fingers, screwdrivers, and other objects away from the openings
in the fan assembly’s housing.

Step 3 Slide the new fan assembly into the chassis, being sure it makes a secure
connection to the midplane.
•If the fan assembly is operating properly, its LED turns green and the fans
start to turn.
•If the LED turns red, try reseating the fan assembly.
Step 4 Tighten the captive screw to secure the fan assembly to the chassis.
Step 5 Rerun all interface cables through the cable management bracket.
Installing Power Entry Modules
This section contains the procedures to install or replace AC or DC PEMs.
Note If you are adding a second PEM for redundancy, or if you have redundant PEMs,
it is not necessary to shut down the system before replacing a PEM.
