LED Name
LED State
Device Status
System Status LED
Blinking Green
System is powering up.
Green
Normal operations. Due to power supply and fan redundancy,
this LED will remain green if a single fan or power supply is
missing or in a failed state.
Blue
The locater function is active.
Amber
Two or more fans (any combination of fan modules or PSU
fans) are disconnected or malfunctioning. The switch will
automatically execute a “graceful shutdown” shortly.
Green
All fan and power modules are operating normally.
Amber
Single fan module is removed or malfunctioning. It is also
amber when a PSU is completely removed or has a stuck
fan rotor.
Red
Two or more fans (any combination of fan modules or PSU
fans) are disconnected or malfunctioning. The switch will
automatically execute a “graceful shutdown” shortly.
Green
PSU is functioning and fully operational. AC is present, Aux
output is ON, and Main output is ON.
Off
PSU has been removed or is not operating properly due to AC
cord being unplugged, its fan rotor being stuck, or an internal
fault.

Status
Yellow
Port is software disabled.
Flashing Yellow
Port failed diagnostics.
Rear Status Indicators
Fan and power supply modules are accessed from the rear panel. Each fan and power supply module
contains an LED that reports the module status.
Fan Status LEDs are on the fan modules, as displayed in Figure A-3.
Table A-3 provides status conditions that correspond to fan status LED states.
The AC Power Supply Status LEDs are on the power supply modules, as displayed in Figure A-4.

LED State
Status
Off
The fan module is not detected. If it is inserted, it may not be seated properly.
Green
The fan is operating normally. This LED state is exclusive to its fan module, and
independent of the states of its neighboring fans and power supplies.
Red
The fan has failed.
