HP 3PAR T-Class Installation and Deinstallation Guide

Providing for Service Access
HP 3PAR Storage System cabinets feature locking rear doors, removable side panels and fascias
to improve access for installing, cabling, and servicing components. See Table 2 (page 14) for
storage system cabinet dimensions.

When establishing an operating site for storage system, provide for adequate access to cabinets
by following the recommendations in Table 3 (page 14).
NOTE: A T800 storage system provides circuit breakers located at both the front and rear of the
system. It is necessary to maintain access to both the front and rear circuit breakers.

NOTE: HP 3PAR cabinets do not require side access during operation. HP recommends leaving
at least 3 ft (91.4 cm) of space on either the left or right side of the cabinet during installation to
allow for the removal of at least one side panel.
Meeting Structural Requirements
Before installing a storage system, establish an operating site to meet the physical, electrical, and
atmospheric requirements of the system.
Weight and Pressure Loads
Depending on the configuration, a storage system may weigh up to 2,000 lb (907 kg). Table 4
(page 14) provides the maximum weights and pressure loads per leveling foot for a cabinet. Use
these values to approximate the structural support required by a system configuration.

Raised Floor Requirements
There are additional structural considerations when installing a storage system in an environment
with raised flooring.
NOTE: This section assumes a standard raised floor construction consisting of the following: 24
in. (61 cm) square or 24 in. (61 cm) X 36 in. (91.5 cm) panels, steel or aluminum stringers, and
pedestal supports attaching to an underlying concrete slab or steel deck.
Prior to installation, verify the raised floor at the operating site meets the specifications described
in Table 5 (page 15).
