Table 4-4 TCC+ Card Faults and Recommended Responses
Fault Type Response
The show cable clock command shows that no
TCC+ cards are installed:
Router# show cable clock
Number of TCCplus Cards in the Chassis: 0
TCCplus Cards are not yet configured
Router#
The console also typically displays the error
message %UBR10KTCC-1-NOTCC: No working
TCCplus card available in the system.
1. Verify that at least one TCC+ card is installed in the chassis. If not,
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.
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.
4. Replace the TCC+ card with a known, working TCC+ card.
An IPC error message (IPCGRP-3-SYSCALL)
occurs for the TCC+ card slots (slot 1/1 or slot
2/1).
1. If this message results after a line card is reset using the hw-module
reset command, it is an informational-only message that indicates
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:
%UBR10KTCC-1-BADTCC: TCCplus card in
slot put under maintenance: reason
The Cisco uBR10012 router detected that the TCC+ card in the indicated
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
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.
