Problem Description

When a WS-F6K-DFC3 daughter board is installed on a WS-X6548-RJ-45 or a WS-X6548-RJ-21 linecard, the linecard will not be recognized by the system and will fail to come online.

Background

A resistor was added to some versions of the WS-X6548-RJ-45 and WS-X6548-RJ-21 linecards, which is incompatible with the WS-F6K-DFC3 daughterboard. When a WS-F6K-DFC3 daughter board and a WS-X6548-RJ-45 or WS-X6548-RJ-21 linecard are mated and installed in a system, if that system is reloaded, the affected linecard and associated daughter board will fail to come back online. The reason they fail to come back online is when the system boots-up, this additional resistor forces the linecard and daughter board to power up too quickly, the system detects they have powered up prior to the Supervisor becoming active and it proactively shuts the linecard and daughter board down. Testing has shown that this problem does not occur if the linecard and daughterboard are brought online through Online Insertion and Removal (OIR). There is only an issue when the entire system is reloaded. As the DFC3 is only supported using Native IOS, this document only covers Native IOS examples.

Problem Symptoms

When a WS-F6K-DFC3 is installed on an affected WS-X6548-RJ-45 or WS-X6548-RJ-21 linecard, the linecard is installed in a chassis the chassis is reloaded and the following system messages are displayed:

On the Supervisor (IOS):

*Mar 17 09:51:39: %PMB-SP-4-CANTPWROFF: Attempts to power down slot 3 failed, card will be disabled.
 *Mar 17 09:51:39: %OIR-SP-3-UNKNOWN: Unknown card in slot 3, card is being disabled
 *Mar 17 09:55:48: %OIR-SP-6-REMCARD: Card removed from slot 3, interfaces disabled
 *Mar 17 09:56:02: %OIR-SP-3-UNKNOWN: Unknown card in slot 3, card is being disabled

After these system messages are displayed, the show module command indicates that the linecard is not present.

IOS Example:

Router#show module 4
% no module in that slot

Workaround/Solution

This problem only occurs when a WS-F6K-DFC3 is installed on the affected hardware versions of the linecards.

Confirm that the linecard is within the affected hardware version that is specified in the Products Affected section. If the product is at the affected hardware level, a replacement can be requested. Use the normal return merchandise authorization (RMA) process to request your replacement.

Note: The RMA will be processed/shipped within 10 business days.

How To Identify Hardware Levels

Example shows a module in slot 3.

NATIVE IOS:

C6000#sh idprom module 3 1
IDPROM image:

  (FRU is 'SFM-capable 48-port 10/100 Mbps RJ45')

IDPROM image block #0:

  block-signature = 0xABAB, block-version = 1,
  block-length = 144, block-checksum = 4525

  *** common-block ***
  IDPROM capacity (bytes) = 256  IDPROM block-count = 2 
  FRU type = (0x6003,258)
  OEM String = 'Cisco Systems'
