Maintenance - Cisco 7000 Series Hardware Installation And Maintenance Manual

Maintenance

This chapter provides maintenance procedures for the Cisco 7010 router and its components. Your
Cisco 7010 is configured to your order and ready for installation and startup when it leaves the
factory. In the future, 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. Software and microcode component upgrades require specific part numbers and
other frequently updated information; therefore, only basic hardware replacement guidelines are
included in this publication. Detailed, up-to-date instructions (called configuration notes) are
shipped with the replacement parts or upgrade kits.
The replaceable system components fall into two categories: those that support online insertion and
removal (OIR) and those that require you to shutdown the system power before replacement.
Because interface processors support OIR, you can remove and replace them while the system is
operating. However, you must shutdown the system power before removing the RP, the SP (or SSP),
RSP7000, RSP7000CI, or any of the internal components (the fan tray, power supply, and arbiter).
Access to the internal components also requires that you remove the chassis cover panel and power
harness cover in the noninterface processor end of the router, which exposes the power supply
backplane connection. If the power is not shutdown, the high current present in the wiring, and on
the backplane if the backplane cover is removed, becomes a hazard. Therefore, always make sure that
the system power switch is turned off before removing any internal components or interior chassis
panels.
This chapter contains information on the following:
•
RP, SP, SSP, RSP7000, RSP7000CI, and interface processor 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)
•
Internal chassis component replacement (instructions for accessing the chassis interior to replace
the following components):
— Fan tray
— Power supply
— Arbiter
