5. Plug in the power supply power cord.

The status LED on the power supply and the fault LED on the front panel of

the RA4000 should now be green, indicating that the new supply and the

storage system are fully operational.

In an RA4000 with the Redundant Power Supply option installed, two

identical power supplies power the RA4000. If either supply is faulty (amber

LED on the supply is lit), it can be replaced with the RA4000 power on,

without affecting normal system operation.

1. Unplug the power cord from the failed supply.

If the system is running, be careful not to disturb the power cord for

the other power supply.

2. Press the catch on the power supply handle and pivot the handle open to

release the power supply. Pull the supply from the chassis.

See Figure 4-23.
