Troubleshooting the Dial Shelf Processor Subsystem

—If power is supplied to the router shelf but the enabled LED remains off, the system has detected a hardware failure. You need to replace the interconnect port adapter.

•Is the link LED on?

The link LED indicates an active connection to the dial shelf. This LED lights when the dial shelf interconnect port adapter is receiving a carrier signal from the dial shelf.

—If the link LED remains off, check the dial shelf interconnect cable connection and tighten the jack screws at both ends of the cable.

—If the connection is good but the link LED remains off, proceed to the section “Troubleshooting the Dial Shelf Controller Card.”

Troubleshooting the Dial Shelf Processor Subsystem

The following sections describe troubleshooting procedures for the DSC card, modem cards, VoIP card, and trunk cards.

Troubleshooting the Dial Shelf Controller Card

Check the following to help isolate a problem with the dial shelf controller card:

•Are the two power LEDs on?

Verify that the power LED and MBus LED light after the dial shelf controller card has been completely inserted into the dial shelf and the system is powered on.

—If both the MBus and power LEDs are on, the card should boot normally. During the boot sequence, the four alarm LEDs should momentarily flash and then turn off. In addition, the two four-character alphanumeric displays show status messages.

After the boot sequence completes, the alphanumeric display should read:

MSTR

If the boot sequence does not finish, contact a service representative for assistance.

—If either the power or MBus LED remains off, try removing and reinserting the card. If the problem persists, contact your service representative. You might need to replace the card.

If the problem persists with a new card installed, remove the dial shelf controller card from the dial shelf slot and examine the backplane for bent connector pins.

To inspect the backplane pins, first power OFF the system to avoid hazards caused by high voltages present on the backplane connectors. Next, remove cards in neighboring slots to allow an unimpeded view of the backplane connectors. Then, using a flashlight, verify that the backplane connectors are in good condition. If you discover bent pins, you need a new backplane. The backplane is an FRU. Contact your service representative to order a new backplane.

•You can also use the show command to diagnose a problem with the dial shelf controller card. Enter the following command:

router> enable

enter password <password>

router# show diag <type {shelf slot}>

Ctrl-Z
