InServ E-Class Storage Server controller node power supply units are located on both sides of
the controller nodes. Each controller node has a corresponding power supply (e.g. node 0,
power supply 0; node 1, power supply 1). The battery is integral to the controller node power
supply. The LEDs are located on the rear of the power supply units as follows (Figure 8-12):
