This document contains instructions for replacing the air filter and the chassis blower in the
Cisco 7000 and Cisco 7507.
Note
therefore, throughout this document, both chassis are referred to as the chassis, with differences
clearly noted.
The air filter, which is integrated with the top front chassis panel, should be kept clean by periodic
vacuuming, and should be replaced if it becomes torn, worn, or dirty. You can access the filter while
the system is operating by removing the bottom front chassis panel. The blower, which is located in
the front interior of the chassis, need only be replaced if the existing blower fails. You must turn all
system power off and remove the top and bottom front chassis panels to access the blower.
