Problem Description

The "FTA-MISMATCH" alarm might be triggered when a fan tray assembly from a specific batch of NCS2006-FTA fan tray assemblies is inserted into a system with line cards that require high cooling.

Background

A specific batch of NCS2006-FTA fan tray assemblies had a blank CLEI Code field, "N/A" in the Product ID field, and an incorrect Version ID when the EEPROM was programmed.

The "FTA-MISMATCH" alarm is triggered if a fan tray assembly from that batch is inserted into a system that contains at least one of these line cards:

NCS2K-MR-MXP-LIC= 10/40/100G MR Muxponder - Licensable for Encryption
NCS2K-200G-CK-C= 50G/100G/200G CPAK Multi Rate Line Card - SD FEC C Band
NCS2K-100G-CK-C= 100G CPAK Multi-Rate Line Card - CP-DQPSK - C-Band
NCS2K-100ME-CKC= 100G CPAK Multi-Rate Line Card - CP-DQPSK - Metro - C-Band
NCS2K-400G-XP= 400G CFP2 MR XPonder
NCS2K-400GXP-L-K9= 400G CFP2 MR XP licensed 100G client bandwidth + 1 port WDM
15454-M-WSE-K9= WSE Card

 

Problem Symptom

The problem symptoms are either:

  • The shelf raises an "FTA-MISMATCH" alarm when an affected NCS2006-FTA fan tray assembly is inserted. The "FTA-MISMATCH" alarm will be displayed if the system contains at least one of these cards: 100G, 200G, 400G, WSE, or MR-MXP.

  • The Cisco Transport Controller (CTC) Inventory output for the affected fan tray has a blank CLEI Code, "N/A" in the Product ID field, and an incorrect Version ID, as shown below.

Representative Picture:

Workaround/Solution

If the "FTA-MISMATCH" alarm is observed, complete these steps in order to recover:

  1. Check the fan tray serial number in the Serial Number Validation Tool to see whether the fan tray is affected.

  2. If the fan tray is affected, open a Cisco Technical Assistance Center (TAC) case for resolution of this issue.

 

Sample CTC Inventory output on a corrected NCS2006-FTA is as shown below:

How To Identify Affected Products

A unit is deemed affected if it meets these criteria:

  • On the CTC, the NCS2006-FTA fan tray assembly raises the "FTA-MISMATCH" alarm.

  • The CTC inventory of the fan tray displays the CLEI Code as blank, the Product ID as "N/A," and an incorrect Version ID, as described in the "Problem Symptom" section.

  • The serial number of the unit shows Affected in the Serial Number Validation Tool.
