Installing a Clock Module into the Cisco MDS 9509 Director

Caution Always wear an ESD wrist strap when handling modules or coming into contact with internal components.

To install the clock module, follow these steps:

Step 1 Remove the new clock module from the antistatic bag.

Step 2 Hold the module with the connectors away from you.

Step 3 Carefully press the module onto the two matching connectors on the backplane.

Note You must install the new clock module in the same position that you removed it.

Step 4 Replace the four screws to secure the clock module onto the backplane.

Step 5 Repeat Step 1 through Step 4 to install any additional clock modules.

Step 6 Replace the back panel safety cover using the 18 screws.

Step 7 Provide power to the power supplies as described in the “Connecting the Power Supplies” section on page 2-28.

Caution In a system with dual power supplies, connect each power supply to a separate power source. In case of a power source failure, the second source will most likely still be available.

Step 8 Verify power supply operation by checking that the power supply LEDs are in the following states:

•INPUT OK LED is green.

•FAN OK LED is green.

•OUTPUT FAIL LED is off.
