Replacing Cisco 7507 and Cisco 7507-MX Internal Components
The replaceable internal components in the Cisco 7507 and Cisco 7507-MX are accessible by removing
the top and bottom front chassis panels. Always turn off the system power before removing the chassis
top front panel. With the top front panel removed, 100A of current is exposed on the front of the
backplane and around the power supply wiring harnesses. Replace the internal components only if you
are advised to do so by a Cisco service representative.
This section contains replacement procedures for the following equipment:
•
Chassis interface (MAS-7500CI=)
•
LED board (MAS-7KLED=)
•
