Installing System Memory in a BayStack ARN Router

4. The Run LED begins flashing and continues to flash until the ARN completes
all diagnostic tests.
5. 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.
6. After completing the diagnostic testing procedure, the boot process begins.
The Run and Boot LEDs indicate the boot status as shown in T
able 1-1.
7. After the boot process completes, the Run LED lights and the Boot LED turns
off, indicating that the ARN is operational.
If the LEDs do not light in this sequence, the network administrator can refer to
Configuring Remote Access to help troubleshoot the problem.
If you need additional assistance, contact your local Bay Networks Technical
Response Center.
Your Next Step
To reconnect the ARN to the network, you need only reboot a valid configuration
file. Refer to Installing and Operating BayStack ARN Routers or to the
Configuring Remote Access guide for instructions.
Contact your network administrator if you need additional information.

associated with these components remain off.
