Powering the VSS2249RQ Storage
Chapter 5
Server
This chapter discusses the available system power configurations and includes
procedures—and important considerations—for controlling power to the
VSS2249RQ Storage Server.
System Power Overview
This section provides an overview of the system-compatible PMs. Input
specifications are also included.
ABOUT THE SYSTEM POWER CONFIGURATION
The VSS2249RQ Storage Server power configuration includes two power sleds,
each containing one factory-installed 12V DC 1600W PSU and one
factory-installed 3.3V power adapter board that provides standby power to the
drives. Regardless of the desired power configuration, both PSUs must be of
the same capacity and form factor.
PMs have active load-sharing and support 1+1 redundancy. This configuration
enables the PMs to operate in an active/passive mode, so during normal system
operation, each PM is functioning at the most efficient level.
If there is a PM failure, the system defaults to the second PM without fault.
During a PM hot-swap, the remaining PM powers the VSS2249RQ Storage
Server until the hot-swap is completed. (PM hot-swaps should be performed
within five minutes to ensure redundancy.) Though a single PM can power the
VSS2249RQ Storage Server indefinitely, both are required to ensure
redundancy.

CAUTION: Use only VES-approved power cords. Do not use any other type of cords
or extension cords. To obtain additional power cords, please contact a Viking
Enterprise Solutions™ sales representative.
CAUTION: A change in power module capacity and/or length will likely require a
change in the power adapter board. Contact a Viking Enterprise Solutions™ support
representative for assistance in upgrading the system power configuration.
