Base Module Diagnostic LEDs
Meaning
Flashes for 1 to 3 minutes, indicating that diagnostic tests are
running. When it lights again and remains on, the ARN is
operational.
Lights for 1 to 3 minutes, indicating that diagnostic tests were
successful and the ARN is booting.
Lights again and remains on when diagnostic failure occurs.
Lights and remains on when the ARN is on and receiving
power.
Lights and remains on when the redundant power supply
(optional) is operating.
Lights and remains on when the ARN cooling fan is 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.
