Readying The Equipment; Installing Rack Rails; Installing Rack Rails For The 1U Power Unit - HP R12000 User Manual

•
Elevated operating ambient temperature—If the equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment might be greater than room
ambient temperature. Install the equipment in an environment compatible with the operating
temperature.
•
Reduced air flow—In the rack, the rate of air flow required for safe operation of the equipment must not
be compromised.
•
Circuit overloading—Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing
this concern.
•
Reliable earthing—Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit, such
as the use of power strips.
•
Electrical requirements—All models require a dedicated (unshared) branch circuit, including an
unshared grounding conductor, that is suitably rated for the specific UPS as stated in "UPS input
specifications (on page 114)."

Installing rack rails

IMPORTANT:
shipping brackets are used with the rail supports. See the optional shipping steps in the rack rail
and component installation sections.
Reinforcement plates are required for rails that support the 2U power unit and 3U battery packs. Plates are
not needed for those rails that support the 1U power unit or 1U battery packs.

Installing rack rails for the 1U power unit
