Installing a Clock Module into the Cisco MDS 9506 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 Step 2 Remove the new clock module from the antistatic bag. Hold the module with the connector away from you and carefully press the module onto the backplane connector. Note You must install the new clock module in the same position that you removed it. Step 3 Step 4 Step 5 Step 6 Replace the three securing screws on the clock module. Grasp both power supply handles and slide the power supply into the power supply bay, ensuring that the power supply is fully seated in the bay. Tighten the captive screws on the power supply to 8 in-lb. Provide power to the PEMs 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 7 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. 2-86 Cisco MDS 9500 Series Hardware Installation Guide OL-17467-02
