System Status Indicators
The System Status Indicators are located just to the left of the primary power supply unit, and
labeled "System." .
The system status indicators should display as follows:
• When the switch is plugged in, within three minutes the STATUS LED should light up green.
• The PSU LED for the plugged in PSU should light up green.
• The PSU LED for the second PSU should light up green only if a second PSU is installed in the
switch for redundancy and Hot-Swap ability and it is connected to a power source. If two PSUs
are installed and only one PSU is connected to a power supply the second PSU LED will be red.
If only one PSU is installed in the switch, the second PSU LED will be off.
