6-4 Power Supply
The SuperServer 1027R-72BRFTP has a 700 watt redundant power supply (PWS-
703P-1R) consisting of two power modules. The power supply has an auto-switching
capability, which enables the it to automatically sense and operate at a 100V-240V
input voltage.
Battery Backup Power (BBP™) Feature
The SuperServer 1027R-72BRFTP features two redundant Battery Backup Power
modules. In the event that power to the SuperServer 1027R-72BRFTP is interrupted,
the BBP feature will provide power to the unit. Each BBP can provide 200 watts
(400 watts total) for five minutes, 100 watts (200 watts total) for 15 minutes or six
seconds of 350 watt (600 watts total) surge. The battery consumes 20 watts while
charging and 2 watts while idle. The redundant battery modules are located in the
front of the chassis.
The BBP modules have a hot-swap capability which allow them to be replaced
without powering down the system. However, when replacing BBP modules, the
IPMI needs to be reset. Please see the IPMI User Guide for more information.
Power Supply Failure
If either of the two power supply modules fail, the other module will take the full
load and allow the system to continue operation without interruption. The PWR Fail
LED will illuminate and remain on until the failed unit has been replaced. Replace-
ment units can be ordered directly from Supermicro. The power supplies have a
hot-swap capability, meaning you can replace the failed unit without powering down
the system.
If both power supply modules fail, the BBP modules will take over the full load. Both
power supplies can be swapped out at this time. IPMI also offers the option of setting
the system to gracefully shutdown to avoid loss of data due to sudden power loss.
