This chapter explains how to troubleshoot problems and/or conditions encountered during the initial installation and provisioning of the Cisco 6100 system.
Each subsection details the following information about installation and provisioning troubleshooting.
The following table lists the installation and provisioning troubleshooting procedures described in this chapter and the section names relative to the procedure.
| Maintenance Description | Section Name |
|---|---|
Multiplexer chassis modules not properly initializing | "Multiplexer chassis modules not properly initializing" |
Line concentration chassis modules not properly initializing | "Line concentration chassis modules not properly initializing" |
Voice calls cannot get through | "Voice calls not getting through" |
The system controller (SC) module status and active LEDs are not solid green after self-test.
Module may be in the wrong slot, may not be properly seated, or chassis may not be properly powered.
1. Ensure that the SC is installed in proper slot. Slots 12 and 30 in the multiplexer chassis (MC) are the only valid slots for the SC. Until SC redundancy is supported, only slot 12 is valid.
2. Remove SC from slot.
3. Reinsert, making sure the top and bottom of the module are squarely seated into the slot.
The module should begin executing its self-test. LEDs will cycle for approximately three to five seconds. On completion of the self-test, the status and active LEDs should be green, and the alarm LED should be off.
If the LEDs do not respond on insertion into slot, ensure that the MC is properly powered. Refer to the Cisco 6100 Set Up and Installation Manual for powering instructions.
4. If the LEDs are not as expected, remove SC and go through same procedure with spare SC.
5. If spare SC executes properly, return the initial SC to Cisco for repair.
The network interface (NI) module status and active LEDs are not solid green after self-test.
Module may be in wrong slot, or may not be properly seated.
1. Ensure that the NI is installed in proper slot. Slots 10 and 11 in the MC are the only valid slots for the NI. Until NI redundancy is supported, only slot 10 is valid.
2. Remove NI from slot. The transmit and receive transmission cables (optical or electrical, depending on the NI type) should not be connected at this point. If so, disconnect them.
3. Reinsert, making sure that the top and bottom of the module are squarely seated into the slot.
The module should begin executing its self-test. LEDs will cycle for approximately three to five seconds. On completion of the self-test, the status and active LEDs should be green, and the alarm LED should be off.
If the LEDs are not as expected, remove NI and go through same procedure with spare NI.
4. If spare NI executes properly, return the initial NI to Cisco for repair.
The ATU-C module(s) status and active LEDs are not solid green after self-test.
Module may be in wrong slot, or may not be properly seated.
1. Ensure that the ATU-C is installed in a proper slot. Slots 1-8, 13-20, 21-28, and 31-38 are the only valid slots for the ATU-C.
2. Remove ATU-C from slot.
3. Reinsert, making sure that the top and bottom of the module are squarely seated into the slot.
The module should begin executing its self-test. LEDs will cycle for approximately three to five seconds. On completion of the self-test, the status and active LEDs should be green, and the alarm LED should be off.
If the LEDs are not as expected, remove ATU-C and go through same procedure with spare ATU-C.
4. If spare ATU-C executes properly, return the initial ATU-C to Cisco for repair.
The LIM status and active LEDs are not solid green after self-test.
Module may be in wrong slot, or may not be properly seated.
1. Ensure that the LIM controller is installed in proper slot. Slots 11 and 12 in the line concentration chassis (LCC) are the only valid slots for the LIM controller. Until LIM controller redundancy is supported, only slot 11 is valid.
2. Remove LIM controller from slot.
3. Reinsert, making sure that the top and bottom of the module are squarely seated into the slot.
The module should begin executing its self-test. LEDs will cycle for approximately three to five seconds. On completion of the self-test, the status and active LEDs should be green, and the alarm LED should be off.
If the LEDs are not as expected, remove LIM controller and go through same procedure with spare LIM controller.
4. If spare LIM controller executes properly, return the initial LIM controller to Cisco for repair.
The LIM module(s) status and active LEDs are not solid green after self-test.
Module may be in wrong slot, or may not be properly seated.
1. Ensure that the LIM is installed in proper slot. Slots 1-10 and 13-22 in the LCC are the only valid slots for the LIMs.
2. Remove LIM from slot.
3. Reinsert, making sure that the top and bottom of the module are squarely seated into the slot.
The module should begin executing its self-test. LEDs will cycle for approximately three to five seconds. On completion of the self-test, the status and active LEDs should be green, and the alarm LED should be off.
If the LEDs are not as expected, remove LIM and go through same procedure with spare LIM.
4. If spare LIM executes properly, return the initial LIM to Cisco for repair.
There is no dial tone when the subscriber attempts to make a phone call.
Continuity in voice wiring path (Main Distribution Frame [MDF] to voice switch) is broken, POTS splitter module is not inserted, or class 5 voice switch line card not provisioned.
1. Check continuity path from Central Office (CO) POTS splitter module to class 5 switch line card.
2. If good, check continuity path from CO POTS splitter to Customer Premise Equipment (CPE) POTS splitter.
3. If good, ensure that dial tone can be achieved from CO voice switch line card (line card is provisioned and operational).
4. Make sure CO and CPE POTS splitters are compatible with each other and with phone set in use.
5. If problem persists, replace CO POTS splitter line card.
There is a dial tone, but the subscriber cannot place a call from the phone.
Faulty POTS splitter module.
1. If dial tone can be provided to the phone terminated to the CPE POTS splitter, but an outbound call cannot be placed, the CO POTS splitter may be faulty.
2. Replace CO POTS splitter line card.
There is a dial tone, but the subscriber cannot receive a call on the phone.
Faulty POTS splitter module.
1. If dial tone can be provided to the phone terminated to the CPE POTS splitter, but an outbound call cannot be placed, the CO POTS splitter may be faulty.
2. Replace CO POTS splitter module.
