AV411B Base 2.5 inch Drive Chassis does not include power supplies consequently demands zero (0) kVA and
generates no (0) kW heat.
NOTE: Site power can be connected to the PDUs at either the top or bottom of the racks.
Grounding
The site and equipment must meet all of the following three conditions of installation for grounding.
• An insulated grounding conductor that is identical in size and insulation material and thickness
to the grounded and ungrounded branch-circuit supply conductors. It must be green, with
or without yellow stripes, and must be installed as a part of the branch circuit that supplies
the unit or system.
• The grounding conductor mentioned above should be grounded to earth at the service
equipment or other acceptable building earth ground such as the building frame in the case
of a high rise steel-frame structure.
• The attachment-plug receptacles in the vicinity of the unit or system must include a ground
. The grounding conductors serving these receptacles must be connected to earth ground
at the service equipment or other acceptable building earth ground such as the building
frame in the case of a high-rise steel-frame structure.
Power connection
The AC power input for the P9500 disk array has a duplex PDU structure. This duplex structure
enables the entire rack to remain powered on if power is removed from one of the two power
distribution panels.
CAUTION: When installing a system, connect the AC cables between the PDUs and PDPs
correctly. Otherwise, a system failure can occur when one of the AC inputs is interrupted.
AC Power - PDU Options
The P9500 is configured for input power using separate rackmount PDU products. PDUs are
available for three phase or single phase power for NEMA and IEC compliance applications.
NOTE: When ordering systems, Hewlett Packard Enterprise does not allow mixtures of different
phase PDUs in a system (even though there are no technical issues). Only upgrade orders can
ship with difference phase PDUs in a system.
