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. About Your System 19
