DC Power Supply
Each DC power supply weighs approximately 2.2 lb and has two independent pairs of
DC input lugs, a fan, and LEDs for monitoring the status of the power supply. The DC
power supply in the services gateway is a hot-insertable and hot-removable
field-replaceable unit (FRU) when the second power supply is installed and running. You
