Chapter 5 Maintaining Your Cisco 7505 Router; Ol-5008-03 B0 - Cisco 7500 Series Configuration Manual

Maintaining Your Cisco 7505 Router
Your Cisco 7505 router is configured to your order and is ready for installation and startup when it leaves
the factory. After you install and configure your Cisco 7505 router, you might have to perform specific
maintenance procedures and operations to ensure that the router is operating properly, to upgrade
specific system components, or to replace components with spare parts or field-replaceable units
(FRUs). This chapter describes maintenance operations required to maintain your Cisco 7505 router; it
includes procedures for installing, adding, and replacing internal router components and replaceable
spare parts.
Detailed, up-to-date instructions (called configuration notes) are available on Cisco.com.
Note
The replaceable system components fall into two categories: those that support online insertion and
removal (OIR) and those that do not (requiring you to turn off the system power before replacement).
For example, you can remove interface processors and replace them while the system is operating;
however, you must shut down the system power before removing the RSP and the single power supply
in a Cisco 7505 with one power supply installed, or before accessing the chassis interior for any other
reason.
This chapter contains specific component replacement instructions for upgrading, removing, or
replacing the following components:
Front panel
•
• Fan tray
Chassis interface (CI) board
•
• Power supply
Caution To help prevent problems, before performing any procedures in this chapter, review the
Recommendations" section on page
Note Interface processor-specific configuration information is included in the companion Interface Processor
Installation and Configuration Guide, which shipped with your Cisco 7505 router, as well as in the
individual configuration notes that shipped with your spare interface processors.
