16OC3X/POS-I-LC-B

800-19733-02

Updated Cisco IOS? software releases will work on versions -02 and below.

Note: This is not a permanent fix for cards which are reverted back to old Cisco IOS software releases.

Problem Description

Some 16OC3X/POS line cards were assembled with a specific vendor's "optics module" and "programmable logic device" (PLD) combination may not boot with certain versions of IOS.

Background

A specific type of optics module introduced on the 16OC3X/POS Line Card in Feb 2002 requires a new IOS or a PLD change to boot up. Not all cards shipped during this time have this combination of optics & PLD so they will work without this issue. About 150 total cards are potentially affected.

This card was first supported in release 12.0(21)S and 12.0(21)ST. Also IOS versions 12.0(21)S1, 12.0(21)S2, 12.0(21)S3, 12.0(21)ST, 12.0(21)ST1, and 12.0(21)ST2 will all exhibit this failure on this Line Card with this specific optic/PLD combination.

Problem Symptoms

The defective line card gets stuck in the IOS-STRT state during initial power on/boot up with no fibers installed or with unlit fiber connections. If the fibers are already lit from another source, such as a far end back-to-back connection, this issue does not occur.

The defective card will start if loopback fibers are plugged in, regardless of the configuration state of the ports (shutdown or no shut"). If a defective card is brought up this way, removing the fibers will cause the card to eventually crash with a "fabric ping failure".

Workaround/Solution

Cisco recommends a loading one of the following Cisco IOS software releases below to resolve this issue for this specific optic/PLD combination:

  • 12.0(21)S4 or later

  • 12.0(21)ST3 or later

  • 12.0(22)S or later

How To Identify Hardware Levels

Use the show diag command to help identify failing boards. If the command output has 800-19733-01, or 800-19733-02 with Deviation: 0, then look at the port coloring to further identify suspect boards. Silver or gray colored ports are the suspect boards. If the output of the show diag command is 800-19733-02 with Deviation: D063311, or if the board is a higher version (800-19733-03 or higher), then boards with either port color are good and new software is not needed.

Note:  If the memory is removed to Identify the PLD version and is not correctly seated when re-inserted then the boot process will hang at IOS START and recursively reboot. If this occurs then reseat the memory.

These silver and gray colored ports (in the first photo below) in combination with old PLD (17-6468-02) at location U3006 won't work without new Cisco IOS software releases listed above.

These 'silver/gray' colored ports will work with the new PLD (17-7091-01) at Location U3006, and any IOS version which supports the 16OC3X/POS-I-LC-B can be used:

These blue colored ports work regardless of PLD version or Cisco IOS software release.
