Four-Post Shelf Kit

The four-post shelf kits allow the drive enclosure and components to be mounted in a variety of
four-post racks. Each enclosure or component requires its own mounting kit.
NOTE: Do not stack the enclosure on top of another one.
Four-post shelves are mounted to the front and rear rails of a four-post rack. Each side requires
two shelf halves and the corresponding mounting hardware. The shelf halves are expandable to
fit racks of different depths. Front shelf halves have left and right pieces, while the rear shelf half
can be used on either side of the rack. When the installation is complete on both the left and right
sides, the equipment can be placed on the shelves and secured to the RETMA rails.

Redundant Power Requirements

Each storage system component is supplied with redundant PCMs. The controller nodes and drive
enclosure are designed to continue operating even when AC power is lost to one of the PCMs.
For this feature to operate properly, each power supply line cord within an enclosure must be
attached to an independent electrical source, each controlled and protected by its own circuit
breaker. Multiple outlets in a power distribution unit or power strip do not constitute an independent
electrical source.
Additionally, each line cord must be plugged into an outlet that is capable of supporting the entire
load of its enclosure.
CAUTION:
power requirements before powering on the system. Special consideration must be given to this
requirement. Failure to do so may result in the overloading of the branch circuit if a power supply
fails, and shuts down the storage system, and cause similar failures in all the equipment connected
to the branch circuit.
CAUTION:
cord-retention mechanisms to prevent accidental disconnection during service activities. HP provides
cord retention mechanisms on HP power supplies but does not supply retention devices for
connection to the customer PDUs or outlets.
