Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Use the following procedure to remove the existing chassis blower:

Step 1 On each installed power supply, turn off the power switch and unplug the power cable from the power source.

Step 2 Remove the front panels. (See Step 1 through Step 6 in the procedure for removing front cover panels in the “Removing and Replacing the Cisco 7507 and Cisco 7507-MX Front Chassis Panels” section on page 6-6.)

Step 3 Locate the blower (see Figure 6-8), which is mounted to the bottom of the backplane. Also, locate the blower power connector, which is connected to a port in the backplane under the white power bar. Note the orientation of the power connector and its orientation in the backplane port.
