4. Beaconing
When a blinking amber LED indicator displays by a port and a yellow triangle attention
indicator displays over the port's connector, beaconing is enabled. See Table 4 on page 72 for
details on port operating states and the status symbol and indicator operation.
5. Not Installed
The port optics are not installed, or the feature that provides additional port function is not
enabled.
6. 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 selecting 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).

7. 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.
