(IPMI).
A red LED indicates a hardware error such as a power failure, fan failure, or overheat-

Power requirements and consumption

There are 4x 1600W redundant power supplies. The power supplies can accept either 110V
(ac) or 240V (ac) input.
With all system resources under full load, the maximum power consumption is 2800W (at an
ambient temperature of 35 C). Idle power consumption is 350W (at an ambient temperature
of 25 C).
The following table identifies valid power configurations:
Max input
Number of working
power per
power supplies
power
supply
4 (Normal mode) 700W
3 (1 failed supply) 933W
2 (2 failed supplies) 1400W
The minimal requirements for a VCA are two 120V/20A circuits with two power supplies per
circuit. If any single power supply fails, the system will continue to operate at full load.
A circuit overload can occur when:
One whole circuit fails; or
Two power supplies on the same circuit fail.
With a maximum of two failed power supplies, a single 240V/20A circuit will support the
VCA running at full load. However, a fully redundant system requires two separate 240V/20A
curcuits with two power supplies per circuit; this configuration can tolerate the loss of any
two power supplies or one complete 240V/20A circuit.
