8.4.3 Replacing a Redundant Power Supply
CAUTION
To support the warm-swap option, ensure that you
replace the power supply SBB with a BA35X-HA
Rev. L01 or later.
The warm-swapping method of replacing a power supply can be used when there
are two power supplies. This method allows you to remove the defective power
supply while the other power supply continues to supply dc power to the pedes-
tal.
The input voltage for each ac power supply is controlled by a single switch on
the ac distribution unit. Setting this switch to off removes power from all power
supplies in the pedestal. To remove power from a single power supply, simply
disconnect the power cable from that power supply and remove the unit.
Use the following procedure to replace a pedestal redundant power supply:
1. Open the door on the front bezel and remove the bezel from the pedestal by
pushing down on the locking tabs at the bottom of the bezel. Unplug the
power cord from the power supply SBB.
2. Press the two locking tabs to release the defective power supply SBB and
slide it out of the pedestal (see Figure 8-3).
3. Insert the new power supply SBB into the guide slots and push it in until the
tabs lock into place. Connect the power cord to the power supply SBB.
4. Observe the LEDs on the new power supply to ensure that the power supply
is functioning properly (see Tables 8-1 and 8-2). Observe the LEDs on both
the power supply and the storage devices for normal operating indications.
5. Replace the front bezel and ensure the bezel locking tabs snap into place and
close the bezel door.
