24 25MAXDATA PLATINUM 7200 IR M6Platform Description

Power Subsystem

The power subsystem consists of the following:

• Power supply modules

• Plug-in VRM converters

• The Power Distribution Board

The power subsystem can be configured with two power supply modules installed for 1+1 redundancy

at 220 VAC.

Power Supply Modules

The output rating of the power supply is 1470 W when operated between 170 VAC and 264 VAC. It

is a current-sharing power supply with auto-ranging input. The power supply is approximately 7.75

inches wide by 13.5 inches deep by 1.4 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 two DC outputs: 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 either embedded or plug-in VRM

converters. The power supply is capable of power-safe monitoring.

In an N+1 configuration, the 12 VDC outputs have active (forced) current sharing. The two externally

enabled outputs have the following maximum ratings:

• +12 VDC: 121 A

• +3.3 VDCSB: 5 A

Each power supply module requires one power cord to supply AC power to the system. When two

power supply modules and two power cords are installed, the system supports (1+1) power cord

redundancy. This feature allows the system to be powered by two separate AC sources. In the 1+1

configuration, the system continues to operate, without interruption, if one of the AC sources fails.
