1.

Verify that at least one TCC+ card is installed in the chassis. If not,

TCC+ cards are installed:

 

install a TCC+ card, because it is required for normal operations.

2.

If only one TCC+ card is installed, it might not have been properly

initialized, so remove it from its slot, wait approximately 30 seconds,

 

and reinsert it.

TCCplus Cards are not yet configured

3.

If only one TCC+ card is installed, its slot might be fault, so remove

 

the card from its slot and install it in the other TCC+ card slot.

 

 

The console also typically displays the error

An IPC error message (IPCGRP-3-SYSCALL)

1.

If this message results after a line card is reset using the hw-module

occurs for the TCC+ card slots (slot 1/1 or slot

 

reset command, it is an informational-only message that indicates

2/1).

 

only that an IPC message was missed while the processor was

 

 

performing the reset of the line card. This error message can be

 

 

ignored.

 

2.

Upgrade the Cisco uBR10012 router to Cisco IOS Release

 

 

12.2(11)BC2 or later release.

 

 

The console displays the following error message:

The Cisco uBR10012 router detected that the TCC+ card in the indicated

%UBR10KTCC-1-BADTCC: TCCplus card in

slot was faulty. If a redundant card is installed, the system passed control

to it. The faulty TCC+ card has been put into maintenance mode. The

slot put under maintenance: reason

following errors are possible:

 

 

Holdover rcvd by Active Card—The active TCC+ card generated a

 

 

holdover interrupt to indicate an error in its clock source.

 

Holdover rcvd by Backup Card—The backup TCC+ card generated a

 

 

holdover interrupt to indicate an error in the clock source being

 

 

received by either the Active or Backup card.

 

Bad Clock reported by CLC(s)—A cable interface line card reported

 

 

that the clock signal being received from the TCC+ card is faulty.

 

TRU Loss of Sync—The clock hardware on the TCC+ card reported a

 

Unknown—An unknown failure occurred, possibly a hardware

 

 

failure.

 

To correct the problem:

 

1.

If an external clock source is being used, check that the clock source

 

 

is valid national clock source, such as a GPS receiver or BITS clock.

 

2.

If the clock source is valid, remove and reinsert the faulty TCC+ card.

 

3.

If the MAINTENANCE LED on the faulty TCC+ card is still lit,

 

 

replace the card.
