Power Supply Indicator
Each hot-pluggable power supply has indicators that provide information about power status, fault, and
the presence of AC power (see Figure 1-6). Table 1-5 lists the power supply indicator codes.
NOTE: Only 2100-W power supply modules are supported on your system. The 2100-W power supply modules
require 180–240 V input from a PDU capable of providing AC current up to 29.2 A at 180 V input. If the power supply
modules are plugged into 110-V electrical outlets, the system will not power up.
