3-2 CHAPTER 3: TROUBLESHOOTING

POWER LED Does Not Light

Make sure that the front and rear cards are pushed fully home, and that the rack enclosure is powered ON.

ISDN/CHANNEL LEDs Do Not Light

Ensure that the Bridge/Router Module is powered on and that the POWER LED is lit. Check the connections at both ends of the ISDN cable. Check that the ISDN port is configured using the CO PO command. See the AccessBuilder ISDN Access Router Software Reference guide for more information about this command. If the LED still fails to light, check the ISDN service by connecting the ISDN port to an alternative ISDN socket. If all of these options fail, contact your ISDN service provider.

Other LEDs Do Not Light

During normal operation the remaining unit LEDs should light and extinguish depending on the action being taken. If the LEDs fail to light in accordance with their function then contact your supplying 3Com reseller for advice.

Bridge/Router Does not Connect to the Remote Device

Check the connections between the Bridge/Router Module, the LAN and the ISDN line. Check that the number you are dialling is correct and that it is connected to a remote device. Check that the remote device is configured to answer incoming calls.

Bridge/Router Disconnects While On-line

Check for any loose connections between your LAN, Bridge/Router Module and the ISDN wall socket. Excessive line noise or interference may also cause an interruption to the line signals in which case you should dial the remote unit again. If this problem persists, contact your 3Com reseller for advice.
