Chapter 6 Maintaining Your Cisco 7507 and Cisco 7507-MX Router

Maintenance Procedures for the Cisco 7507 and Cisco 7507-MX

Step 2 Listen for the blower; you should immediately hear it operating. In a noisy environment, it might not be

possible to hear the blower operating. If this is the case, place your hand near the exhaust vent and feel

for air coming from the vent. If you do not hear the blower or feel any air coming from the exhaust vent,

turn off the system power and do the following:

a. Remove the top and bottom front chassis 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.)

b. Check the blower power connector to ensure that it is fully seated in the backplane port; pinch the

sides of the connector and push it firmly into the port.

c. Check the two wires between the blower and the power connector: the red or purple +24V wire and

the black ground wire. Ensure that they have not pulled out of the power connector; pinch each wire

near the back connector and push it firmly into the connector.

d. Replace the front chassis panels. (See Step 1 through Step 9 in the procedure for replacing 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 Turn the power supplies back on, and check again for proper blower operation.

If after several attempts the blower does not operate, or if you experience trouble with the installation,

contact a service representative for assistance.

This completes the blower replacement procedure.
