5.5.3 Line Card Problems
If you need to remove or replace a line card as part of the troubleshooting steps below, see Chapter 6,
Upgrading and Maintaining the Cisco 6260 System, for instructions.
Table 5-5 Line Card Problems
Symptom Steps to Take
All LEDs are off.
1. Check the Power LED on the NI-2 card and the Input OK LEDs on the PEMs. If none
of the LEDS are lit, or if the red Out Fail LED on either PEM is lit, troubleshoot the
PEMsee the Alarms section on page 5-17.
2. If the NI-2 card Power LED is off, remove the card from its slot and check for bent
or broken pins on both the card and the backplane. If you find damaged pins on the
card, replace it. If you find damaged pins on the backplane, contact the Cisco TAC.
All ports on a card fail to come
up (modems do not train). Status
LED might be red, indicating
that the line card failed to boot or
failed its power-on self test.
1. Enter the show ipc nodes command to find out whether there is a communication
problem between the line card and the NI-2 card. There should be an entry in the
resulting display for each line card (SMB IP Slot n) and for the NI-2 card (IPC
Master). If there is an entry for each card, go to step 4.
2. If one or more cards are not listed, enter show oir status. If the resulting display
indicates that the card in question is loading new code, wait a few minutes and reenter
the command. (Usually, 2 to 3 minutes is long enough to wait.) The card status should
change to
running.
3. Enter the command show dsl int atm slot#/port#. If the status says Microcode
downloading
, wait 10 minutes. When the download is complete, the card reboots and
comes up normally.
4. Check the ALARM LEDs on the NI-2 card or enter show facility-alarm status to
determine the alarm status of the system. If any alarms are indicated, see the
System-Wide Problems section on page 5-3 for instructions on how to
troubleshoot alarms.
5. Enter the command show dsl status and examine the results to ensure that the card is
configured to be in its current slot. (In the Names column of the resulting display, the
slot number appears as part of the port ID. For example, in ATM19/2, the slot number
is 19. Nothing is displayed for slots that are not configured.) If necessary, use the slot
command to update the configuration, or move the card to the correct slot. If the line
card is a 4xflexi
1
, it will not function unless you use the slot command to configure
either CAP or DMT operation.
6. Reset the line card by disconnecting it from the backplane and reseating it in its slot.
7. Install the card in another slot.
8. If the problem persists, replace the line card.
