AC Power Supply
Each AC power supply weighs approximately 2.3 lb and consists of one AC appliance
inlet, a fan, and LEDs for monitoring the status of the power supply. The AC power supply
is a hot-insertable and hot-removable field-replaceable unit (FRU) when the second
power supply is installed and running. You can install the replacement power supply
without powering off the services gateway. The AC power supply gives an output of 650
W and supports both low line voltage (100–127 VAC) and high line voltage (200–240
VAC).
Figure 7 on page 24 shows the AC power supply.

Figure 8 on page 24 shows the location of the LEDs on an AC power supply. Each AC
