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. In SX1024 and SX1400 PS1 and
PS2 are combined into one LED.
