HP 3PAR T-Class Installation and Deinstallation Guide

NOTE: It is necessary to remove the side panels of a T800 cabinet when routing the main power
cords up through the top of the cabinet.
• To remove a side panel, use a #2 Phillips screwdriver to loosen the screws securing the side
panel. Using the handle, pull toward you while lifting up slightly“Removing a Side Panel from
the Cabinet” (page 52)

Adjusting Power Cables
After placing the cabinet, assess the power requirements of the system and determine if the operating
site can support redundant power as described in Section (page 17).
For optimal data accessibility, HP strongly recommends:
• A redundant power configuration using independent sources to provide a separate dedicated
200-240 VAC electrical circuit for each PDU in the system.
• A fully redundant power configuration within the system, as described in “Supporting Redundant
Power” (page 17).
NOTE: If a cabinet does not have components installed in the top four bays (bays 0–3, or the
highest 16U of the cabinet), the two upper PDUs (PDU 0 and PDU 1) are not used to power the
system and do not need to be connected. Redundant power is still supplied to the lower bays in
the cabinet through PDU 2 and PDU 3.
