3.2.1.3 Power Supply Status LEDs
There are two power supply inlets in the system (for redundancy). The system can operate with
only one power supply connected. In case the power supply is an FRU, a second power supply
unit can be added to support hot-swap ability. Each power supply unit has a single 2 color LED
on the right side of the unit, that indicates the status of the unit.
The primary power supply (PS) unit is located on the left side, and the secondary unit is located
on the right side.
