Power Subsystem; Power Supply Modules - Intel S7000FC4UR - Server System - 0 MB RAM Product Manual

Power Subsystem

The power subsystem consists of:
•
Power supply modules (see below)
•
Power distribution board (see
1+1 power supply redundancy or operation with a single power supply is supported under
all configurations at 220 VAC. At 100 or 115 VAC, 1+1 power supply redundancy or
operation with only one power supply is supported only if the power supply DC limits are
not exceeded.
If your desired configuration exceeds the power supply limits, two power supplies are
required. The two power supplies will operate in current-sharing mode to deliver the
additional power needed for your configuration. The two power supplies must be sourced
from separate AC circuits so they do not exceed maximum AC inlet current. Exceeding
the maximum AC inlet current may cause a circuit breaker to trip.
In a redundant configuration, the system supports one fault at a time, either one fan fault
or one power supply fault, and it supports hot-swapping one component at a time.

Power Supply Modules

The output rating of each power supply is 1570 watts when operated between 180 VAC
and 264 VAC. It is current-sharing with auto-ranging input. The power supply is 7.75
inches wide, 14.5 inches deep, and 1.47 inches high. The power supply modules have
universal AC input with Power Factor Correction (PFC) Distributed Power Supplies
(DPS). The AC input receptacle is an IEC-320 C14.
The power supply has DC outputs of 12 V and 3.3 VSB. The 12 V main power is
distributed through the server and is converted locally at the point-of-load using
embedded VRM converters. The power supply is capable of power-safe monitoring.
The maximum AC input current is:
•
100 - 127 VAC: 12 A
•
200 - 240 VAC: 7 A
The maximum input current listed is the maximum AC inlet current that can be drawn by
the power supply / supplies. If two power supplies are installed, then this value is the
maximum combined input current for both AC inlets.
In an N+1 configuration, the 12 VDC outputs have active (forced) current-sharing. The
two externally enabled outputs have these maximum ratings:
•
+12 VDC: 121 A
•
+3.3 VDCSB: 5 A
