LEDs

OK LED, one tricolor:

• Off—PIC is offline and safe to remove from the router

• Green—PIC is operating normally

• Yellow—PIC is initializing

• Red—PIC has an error or failure

APP LED, one green per port:

• Off—Service is not running

• Green—Service is running under acceptable load

Port LEDs, one tricolor per port:

• Off—Not enabled

• Green—Online with no alarms or failures

• Yellow—Online with alarms for remote failures

• Red—Active with a local alarm; router has detected a failure
