Maintenance

This chapter provides maintenance procedures for the Cisco 7000 router and its spare and
field-replaceable units (FRUs). Your Cisco 7000 router is configured to your order and ready for
installation and startup when it leaves the factory. As your communication requirements change, you
may want to upgrade your system, add components, or change the initial configuration. This
chapter describes the procedures for installing, replacing, and reconfiguring interface processors,
and for adding and replacing internal system components such as the system blower, arbiter board,
and front panel components. Software and microcode component upgrades require specific part
numbers and other frequently updated information; therefore, only basic replacement guidelines are
included in this publication. Detailed, up-to-date instructions (called configuration notes) are
shipped with the replacement parts.
The replaceable system components fall into two categories: those that support online insertion and
removal (OIR) and those that require you to shut down the system power before replacement.
Redundant power supplies, interface processors, and the air filter support OIR and can be replaced
while the system is operating. You must, however, turn off all power supplies before replacing the
RP, the SP (or SSP), RSP7000, RSP7000CI, or any of the internal components (the LED board,
arbiter board, or system blower). Access to the internal components also requires that you remove
the front panels to access the chassis interior, which exposes the power supply wiring and backplane.
Warning If all power supplies are not shut down, the high current (100A) present in the wiring and
on the front of the backplane becomes a hazard; therefore, always make sure that all power supply
switches are turned OFF before removing the front chassis panels and exposing the chassis interior.
This chapter contains information on the following:
• RP, SP, SSP, RSP7000, RSP7000CI, and interface processors installation and configuration
(general instructions for installing, replacing, upgrading, and reconfiguring the processor
modules and associated components and, when necessary, instructions for using software
configuration commands)
• Power supply installation and replacement
• Air filter cleaning and replacement
• Internal chassis component replacement (instructions for removing the front chassis panels and
replacing the system blower, the arbiter board, and the LED board)
Warning Before performing any procedures in this chapter, review the section “Safety
Recommendations” in the chapter “Preparing for Installation.”
