Connecting Cables
To reconnect the ARN:
1.Reconnect any console or network cables that you disconnected from the
front and back panel connectors.
2.Connect the appropriate cabling to the new Ethernet, token ring and/or
serial interfaces: COM, STP, AUI, or 10Base-T.
Refer to the Cable Guide for Routers and BNX Platforms for the cables
available from Bay Networks.

Ensuring a Successful Installation
After reconnecting the ARN to the network, you can ensure a successful upgrade
by checking the diagnostic LEDs on the front panel of the base module
(Figure

Figure 1-16.ARN Base Module Diagnostic LEDs
When you power on the ARN, the following sequence of front panel LED activity
should occur:
1.All base module LEDs light momentarily; this tests that the LEDs are
operational.

2.The Run, Boot, and Fail LEDs count through a short, initial startup sequence.
3.The Pwr (power) LED lights and remains on.
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.

After completing the diagnostic testing procedure, the boot process begins.

off, indicating that the ARN is operational.
If the LEDs on the ARN light in this sequence, your upgrade is successful.
Contact the network administrator to verify that the ARN is now connected to the
network.
If the LEDs do not light in this sequence, the network administrator can refer to
Configuring Remote Access to help troubleshoot the problem.
Note: If the ARN does not contain an expansion module, an adapter module, a
redundant power supply, a data collection module, or a Flash card, the LEDs
associated with these components remain off.
If you need additional assistance, contact your local Bay Networks Technical
Response Center.
Your Next Step
To connect the new interfaces to a network and modify the ARN configuration
file, you must follow the appropriate installation procedures. Refer to
