Alarm LEDs
Table 1 -6 and Tab le 1-7 list the alarm LED colors and their meanings.
Power Status LEDs
The switch can operate with one or two DC power sources. Each DC input has an associated LED that
shows the status of the corresponding DC input. If power is present on the circuit, the LED is green. If
power is not present, the LED color depends on the alarm configuration. If alarms are configured, the
LED is red when power is not present; otherwise, the LED is off.
If the switch has dual power sources, the switch draws power from the power source with the higher
voltage. If one of the DC sources fails, the alternate DC source powers the switch, and the corresponding
power status LED is green. The power status for the failed DC source is either off or red, depending on
the alarm configuration.
Table 1 -8 lists the power status LED colors and meanings.
Note The Power A and Power B LEDs show that power is not present on the switch if the power input drops
below the low valid level. The power status LEDs only show that power is present if the voltage at the
switch input exceeds the valid level.
For information about the power LED colors during the boot fast sequence, see the “Verifying Switch
Operation” section on page2-47.
