HP SureStore 7400 Power Supply System/Configuration Specific Instructions

Replacement Procedure: HP StorageWorks Virtual Arrays and

Disk Systems Power Supply

Replace a power supply as soon as possible when troubleshooting indicates a power supply failure.

When a

power supply fails, the remaining power supply provides proper voltage to the disk system.

However, if the

remaining power supply fails before the first power supply is replaced, the disk system will turn off.

You do not need to turn off the array to replace a power supply.

Caution

Do not remove a power supply from an operating product until you

have the replacement parts and are ready to install them.

An empty slot will

cause uneven cooling and eventual overheating.

Caution

Parts can be damaged by electrostatic discharge.

Please ensure

that ESD measures are in place.

Step 1

Open the Power Supply Replacement Kit and inspect the contents.

Note

Two models of power supplies are available for the array

: the older A6211-69001 and the newer A6211-96002.

The A6211-69002 is not certified to operate with the A6211-69001 in the same array enclosure for an extended period of

time. To ensure proper array operation, the power supplies should not be mixed in the same array.

See Figure 1 for

instructions on locating the power supply part number.

Step 2

Disconnect power cord from module.

Step 3

Loosen the cam lever screws (A in Figure 1).

Step 4

Pull out both cam levers at the same time (B in Figure 1).

Step 5

Pull the module from the slot (C in Figure 1).

Caution

DO NOT leave the power supply slot empty for more than 2 minutes, as proper cooling/airflow

depends on the slot being filled.
