Introduction
The AC version of the IBM
subsystem that provides up to 500-Watt DC with 100–240 VAC input with current and remote
sense regulation. The power subsystem consists of one or two 500-Watt power supply modules. A
system with two modules forms a redundant, hot-swappable (1+1) power subsystem. There is a
single bi-color LED to indicate power supply status. Refer to Table 10 for conditions of the power
supply LEDs.
Table 10.
