HP 6400/8400 HP StorageWorks power UID replacement instructions (533484-001, M - Page 2

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. 1 2  Figure 1 Removing disk enclosure bezel ears and thumbscrews b.
