Rear Panel LED:
In the SN5400 and SN5600 switches there are two power supply inlets in each system (for
redundancy). The system can operate with only one power supply connected. Each power supply
unit has two single color LEDs on the right side of the unit, that indicate the status of the unit.
When looking from the FRUs side, the first power supply (PS) unit is located on the left side of the
system, and the second unit is located on the right side.
