Maintenance Procedures for the Cisco 7513, Cisco 7513-MX, and Cisco 7576

Removing and Replacing the Cisco 7513, Cisco 7513-MX, and Cisco 7576 Blower

Module

In the Cisco 7513, Cisco 7513-MX, and Cisco 7576, the blower provides cooling air to the internal

system components. When you view the chassis from the noninterface processor end, the blower module

is located above the card cage. (See

place. The front panel LEDs are located on a printed circuit board inside the blower module. If one of

these LEDs fails, the blower module must be replaced. The LED board inside the blower module

assembly is not separately replaceable.

Warning

Although the system should not be operating when you remove the blower module, it is not necessary

to turn OFF system power before removing the blower module. However, with the system power ON

and the blower module removed, high current is exposed on the blower module power connector at

the backplane; do not insert conductive items into the empty blower module opening. After an

operating blower module is removed, the blower impeller blades will continue to spin for

approximately two minutes; do not insert anything into the module's vent holes while the impeller is

spinning.

With chassis power on and the blower module removed, no cooling air is circulating through the system.

Caution

Replace the blower module before the system overheats. The system will shut down approximately 2

minutes after reaching the shutdown temperature threshold.

Use the following procedure to remove and replace the blower module:

Loosen the captive screws that fasten each end of the blower module using a flat-blade screwdriver. (See

Step 1

Figure

Grasp the handle on the front of the module and slowly pull it straight out of the chassis. (See

Step 2

Figure

Replace the blower module. Using both hands to handle the module, and with the intake vents on the

Step 3

blower module facing down and the "Insert This Side Up" label facing up, insert the module into the

chassis opening. Keep the module as straight as possible as you guide it into the chassis.
