LED Fault LED Description
On Off Off Normal operation. EPS/RPS is not connected or not powered
On On Off Normal operation. EPS/RPS is available.
On On/Off Blinking Unit has experienced a fault and another LED will be blinking to
determine fault.
Off On Blinking EPS/RPS is running unit in failover mode. No AC power to the unit, or
the internal power supply has failed
Off Off Off Unit is un-powerd by AC input line and the external EPS/RPS
On Blinking Blinking EPS/RPS unit has experienced a fault
On Blinking Off EPS/RPS unit is unavailable to power the unit in the event of an internal
power supply failure. The external EPS/RPS is designed to provide
power to one of its connected switch devices at a time. The Power
Status LED on the external EPS/RPS unit will also be blinking for this
device.
