Power, System Error, and Unit Beaconing Indicators
The green or amber indicators on the far left of the front view simulate the
power and system error LEDs on the actual switch.
— Power Indicator. The green indicator (PWR) simulates the power LED on
the actual switch. When the indicator illuminates, the switch is connected
to facility AC power and is operational. The indicator will be on if either
power supply is operating.
— System Error Indicator. The amber system error light indicator (ERR)
simulates the system error light on the actual switch. When this indicator
illuminates, an event has occurred requiring immediate attention, such as
a system, power supply/fan, or port failure. View details of system errors
by clicking Logs > Event Log on the Element Manager menu bar. The
indicator in the Hardware View and the LED on the actual unit remains
illuminated until you clear the event by right-clicking on the front view
away from a hardware component and clicking Clear System Error
Light.
— Unit Beaconing Indicator. The amber system error indicator blinks if unit
beaconing is enabled. Enable and disable unit beaconing by right-clicking
on the front view away from a hardware component and clicking Enable
Unit Beaconing. You can only enable beaconing if there are no system
errors (the system error indicator is off).

Power Supply Status
Each AC power connector indicates the location of an internal power supply.
An amber, service-required LED indicator is located in the upper left corner
of each AC power connector. The indicator illuminates if the power supply
has failed and requires service. The indicator is off if the power supply is
active.
When a red and yellow diamond ( ) displays on a power connector, the
internal power supply for that connector has failed. Note that the switch
operates with one power supply failure; however, you should replace the
power supply as soon as possible to retain redundancy.
