Reference Guide for the Model RT328 and Model RH348 ISDN Routers

Test LED

When the router has been turned on for about 10 seconds, the Test LED blinks at a rate of about
0.5 Hz. If the Test LED does not blink, or if it stops blinking, there is a fault within the router.
Cycle the power and see if it recovers. If the error persists, you might have a hardware problem
and should contact technical support.

LAN Link LED

If the LAN Link LED does not light when the Ethernet connection is made, check the following:
• Physical Ethernet cables
Make sure that the connections are secure at the router and at the hub or workstation.
• Connected hub or workstation
Make sure that the connected hub or workstation is powered on.
• Configuration of the router
Make sure that you configured the router to use the correct Ethernet interface (AUI or UTP)
for your LAN connection. The factory default interface for a router that is not configured is the
UTP port.
• Correct Ethernet cable
If you are connecting a Model RT328 router directly to a workstation or to the uplink (MDI)
port of a hub, use the red crossover cable. If you are connecting a Model RT328 router to a
normal (MDI-X) hub port, use the white straight-through cable.
Workstations should be connected to the Model RH348 router hub ports using straight-through
cables.

Troubleshooting the ISDN Line

Within the first two minutes after power is turned on to the configured router, the ISDN D LED
should light. If the LED does not light, check the physical connection of the ISDN line, referring to
the installation information in this guide.
If the physical connection is correct, the problem should be diagnosed using the internal Manager
interface. Refer to instructions in this guide regarding the use of the Manager interface.
