Maintenance Procedures for the Cisco 7513, Cisco 7513-MX, and
Cisco 7576
Cisco 7576
To replace internal spares, all of which are inside the noninterface processor end of the router, you must
remove the chassis cover panel and expose the chassis interior. The Cisco 7513, Cisco 7513-MX, and
Cisco 7576 are housed in the same chassis and use the same power supplies. If a procedure is specific to
one model or the other, it is noted within that procedure.

one model or the other, it is noted within that procedure.
Warning
If the power is not shut down before removing chassis cover panels, high current can become a
hazard. When the power harness cover is removed, the high current present in the wiring and on the
backplane also becomes a hazard. Removing metal cover panels when the system is operating also
compromises the EMI integrity of the system. Therefore, always turn off the system power before
removing metal cover panels, and remove cover panels only when it is necessary to replace internal
components.
