Power Supply Subsystem
The 12 V hot-swap power supply modules are rated at 1390 W over an input range of 200
- 240 VAC, and at 990 W over an input range of 100-127 VAC.
The power supply module has two outputs, that is, +12 V and +5 Vsb. The standby
voltages +5 Vsb is active anytime AC input power is applied to the power supply.
The power supply module is connected to the main board directly and can be used in 1+1
redundant mode.
Note: Two power supplies must be installed and plugged in when a 110 V outlet is used. Hot-
swapping and redundancy are not available under this condition.
One power supply can be used when it is connected to a 220 VAC outlet. Under this
condition, redundancy is available and a power supply can be hot-swapped if necessary.
Note: This value is applied to one power supply.
