Meaning
Lights and remains on when the redundant power supply (optional) is
operating.
Lights and remains on if one or more ARN cooling fans stop operating.
Lights and remains on when the base module is operating properly.
Flashes slowly to indicate that the module is running its diagnostic
tests. Flashes rapidly to indicate that the module failed its diagnostic
tests.
Lights and remains on when adapter module #1 is operating properly.
Flashes slowly to indicate that the module is running its diagnostic
tests. Flashes rapidly to indicate that the module failed its diagnostic
tests.
Lights and remains on when adapter module #2 is operating properly.
Flashes slowly to indicate that the module is running its diagnostic
tests. Flashes rapidly to indicate that the module failed its diagnostic
tests.
Lights and remains on when an expansion module is installed and
operating properly. Flashes slowly to indicate that the module is running
its diagnostic tests. Flashes rapidly to indicate that the module failed its
diagnostic tests.
Lights and remains on when an RMON DCM is installed and operating
properly. Flashes slowly to indicate that the module is running its
diagnostic tests. Flashes rapidly to indicate that the module failed its
diagnostic tests.
Lights and remains on when the ARN contains a flash memory card in
its PCMCIA slot.
