HP StorageWorks power UID replacement instructions (533484-001, March 2009)

Removing the power UID
1. Power down the enclosure.
a. For the MSA6X/7X: Power down any attached servers (see
your server documentation). Press the On/Standby button on
the disk enclosure, and wait for the system power LED to go
from green to amber. Disconnect the power cords.
b. For the EVA: Power down the array (controller enclosure and
disk enclosures) with HP Command View EVA or, on the
EVA4400 only, the Web-based operator control panel
(WOCP). Powering down the controller enclosure also removes
power from the disk enclosures.
2. Remove all cabling from the external enclosure components. Ensure
all cabling is marked so as to facilitate recabling later.
3. Remove the enclosure bezels and enclosures from the rack.
WARNING!
A disk enclosure fully populated with disk drives is
heavy. Remove the disks and place them on a clean
surface, preferably stacked in the order removed,
before removing the enclosure. Otherwise, two people
are required to remove the enclosure from the rack to
prevent injury.
a. For the MSA6X/7X and EVA disk enclosures: Pull off the left
and right bezel ears (1, Figure 1), loosen the front panel
thumbscrews (2) that secure the enclosure faceplate to the front
of the rack, and remove the enclosure from the rack.
