14 The FRU Replace window appears. Follow the instructions on the screen to complete replacement of the power supply.
15 From the Step 1 window, complete the following steps:
a At the rear of the cabinet, look for a disk array power-fan module with a blue Service Action Allowed indicator. Refer to “Controller Module Connectors and LEDs” on page 16 for the location of the indicator lights on the power-fan module.
b If the Service Action Allowed indicator is illuminated blue, return to Server Management Client and click OK.
Note: If the Service Action Allowed indicator is not illuminated blue, return to Server Management Client, and click Cancel. Notify Teradata customer services of the problem you encountered. Make sure to use a contact method that is in accordance with your service contract (for example, initiate or update an incident through Teradata @ Your Service).
16 From the Step 2 window, complete the following:
Caution: When replacing the power-fan module, take care to avoid damaging the fibre optic cables. Bending or damaging fibre cables can result in degraded performance or data loss. Fibre cables are fragile and can break easily. Do not pinch the cables with tie wraps, step on them, or bend them at sharp angles.
a At the rear of the cabinet, find the power-fan module that has a blue indicator light on. b Turn off the failed power-fan module. Make sure to power down only the failed power-
fan module.
