Cisco Systems 7500 Series Manual De Usuario

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.
