9.3 Power Subsystem
The power subsystem consists of:
x Power supply modules (PSU)
x A power distribution board (PDB)
There are four power bays providing space for up to four power supply modules that connect to the power distribution
board (PDB). The dimensions of the power supply module is 3.72-inches (W) x 15.75-inches (D) x 1.57-inches (H),
(9.45[W] x 40.0[D] x 4.0[H] cm) There are two dual-motor fans located within each power supply module drawing air
through the hard drives and across the power distribution board. Each power supply module has a handle to assist
insertion and extraction without tools.
The PDB distributes the power in two ways. There are connectors on the back edge of the board that mate to the
power supplies. In addition, there are cables that route power up to the main board and to the hot-swap backplane.
The QSSC-S4R Server System power subsystem supports up to four 850W high efficiency power supplies that all
connect to the PDB.
The total system is rated 100-127/200-240V AC, 50/60 Hz, 28/14A. The minimum system configuration requires
installation of at least two PSU’s. The PSU is considered hot-swappable. The system can be configured to support
*True AC redundancy or non-AC redundancy.
NOTE: *True AC redundancy is recommended for systems used for critical business applications. This will
result in the system to continue operation during a power failure as the redundant part of the subsystem is
plugged into a separate AC source [e.g. Un-interruptable Power Supply (UPS)).
