Ensuring a Successful Installation
After connecting the ARN to the network, you can ensure a successful installation
by checking the diagnostic LEDs on the front panel of the base module (refer to
Figure 3-1 ).
When you power on the ARN, the following sequence of front panel LED activity
should occur:
• All base module LEDs light momentarily; this tests that the LEDs are
operational.
• The Run, Boot, and Fail LEDs count through a short, initial startup sequence.
• The Pwr (power) LED lights and remains on.
• The Run LED begins flashing and continues to flash until the ARN completes
all diagnostic tests.
• As the diagnostic procedure tests each module, the LED representing that
module flashes slowly. If the module passes its diagnostic test, the LED
remains on. If the module fails its diagnostic test, the Fail LED remains on
and the module LED flashes rapidly.
• After completing the diagnostic testing procedure, the boot process begins.
The Run and Boot LEDs indicate the boot status as shown in
Table 3-11 .
• After the boot process completes, the Run LED lights and the Boot LED turns
off, indicating that the ARN is operational.
If the LEDs on the ARN light in this sequence, your installation is successful.
Contact your network administrator to verify that the ARN is now connected to
the network.
