Problem Description

A limited quantity of V02 GLC-SX-MM-RGD units shipped between late February to early September 2016 and a limited quantity of V02 GLC-ZX-SM-RGD units shipped between late April to September 2016 with serial numbers that begin with 'ACW' might have an incompatibility issue if used in CGS 2520, IE 3010, CGR-2010 GRWIC (CGS), IE2000, or IE2000U switches.

When the issue occurs, the SFP appears inoperative and random host I2C error messages might be seen or high CPU usage until the module is removed or system power-cycled which temporarily resolves the problem.

Background

Cisco is aware of an occurrence where this has happened in a customer environment. Only a specific combination of products and SFPs are impacted.

Problem Symptom

These HARDWARE products with SFPs (GLC-SX-MM-RGD and GLC-ZX-SM-RGD) are impacted:

Table 1: Impacted Platform Switches

CGS 2520 Switches	IE 3010 Switches	CGR-2010 GWIC(CGS)	IE-2000 and IE-2000U Switches
CGS-2520-24TC, CGS-2520-16S-8PC	IE-3010-24TC, IE-3010-16S-8PC	GRWIC-D-ES-2S-8PC, GRWIC-D-ES-6S	IE-2000-16PTC-G-E, IE-2000-16PTC-G-L, IE-2000-16PTC-G-NX, IE-2000-16TC-G-E, IE-2000-16TC-G-L, IE-2000-16TC-G-N, IE-2000-16TC-G-X, IE-2000-4S-TS-G-B, IE-2000-4S-TS-G-L, IE-2000-4TS-G-B, IE-2000-4TS-G-L, IE-2000-8TC-G-B, IE-2000-8TC-G-E, IE-2000-8TC-G-L, IE-2000-8TC-G-N, IE-2000U-16TC-G, IE-2000U-16TC-G-X, IE-2000U-16TC-GP, IE-2000U-4S-G, IE-2000U-4TS-G, IE-2000U-8TC-G

 

When the issue occurs, the V02 SFP (GLC-SX-MM-RGD or GLC-ZX-SM-RDG) with serial numbers that start with 'ACW' appear inoperative and random host I2C error messages might be seen or there might be high CPU usage until the module is removed or the system power-cycled which temporarily resolves the problem.

Examples of error messages:

• %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding (the Power Supply Unit (PSU) is OK, do NOT request a Return Material Authorization (RMA), remove the SFP)
• CPU Proc = SFF8472 running way too high (~40%)

  %SYS-3-CPUHOG: Task is running for (2098)msecs, more than (2000)msecs (0/0),process = SFF8472. -Traceback= 0x15B0860z 0x15A967Cz 0x15A96FCz 0x167A654z 0x167C7ACz 0x167C95Cz 0x16523A0z 0x164C854z 0x16535DCz 0x1671E58z 0x1672088z 0x1177124z 0x1179C04z 0x16545ACz 0x12045E0z 0x1209420z

• Console Message - hulc_sfp_iic_intf_read_eeprom sfp _index 1 yeti_iic_read_retry fail
• Cisco IOS^® CLI - '#show int transceiver' = 'No transceiver present'

Workaround/Solution

Cisco will replace V02 (GLC-SX-MM-RGD and GLC-ZX-SM-RGD) parts that have 'ACW' at the start of the serial number only if it used on the switch product IDs (PIDs) referenced in the Problem Symptom section (CGS 2520, IE 3010, CGR-2010, GRWIC (CGS), IE2000, or IE2000U).

In order to replace the affected hardware, request an RMA through your normal support process.

Refer to the How to Identify Affected Products section for instructions on how to validate impacted units.

How To Identify Affected Products

Complete these steps:

1. Use Table 1 in the Problem Symptoms section in order to determine if the product switch is impacted. If the switch is not listed, there is not an incompatibility issue and no action is needed. If listed, continue to next step.
2. Identify the version and serial number of the GLC-SX-MM-RGD or GLC-ZX-SM-RGD. There are two methods that can be used to identify the version and serial numbers.

   Method 1: Visually Inspect the Physical Product Label

   For GLC-SX-MM-RGD, on the main serial number label on top of the unit, the serial number needs to begin with 'ACW'. The version ID (VID) is V02. The Cisco part number (CPN) is 10-2274-02.

   The side labels have a CLEI of WDUIAACBAB with an ECI of 186657 on the scannable side label barcode.

   Note: The serial number 'ACW' prefix needs to be verified along with one of the other attributes (V02, CPN, CLEI, or ECI).

   See this image:

   

   For GLC-ZX-SM-RGD, on the main serial number label on top of the unit, the serial number needs to begin with 'ACW'. The VID is V02. The CPN is 10-2266-02.

   The side labels have a CLEI of COUIAF5CAB with an ECI of 186659 on the scannable side label barcode.

   Note: The serial number 'ACW' prefix needs to be verified along with one of the other attributes (V02, CPN, CLEI, or ECI).

   See this image:

   

   Method 2: Find the Serial Number and Version Remotely from the Switch

   Enter the show inventory command in order to obtain the serial number and version of the SFP. See this image:

   

3. Once the serial numbers are obtained, use the Serial Number Validation Tool in order to verify affected units.

   The serial number date code range is between ACW1949xxxx and ACW2039xxxx for the GLC-SX-MM-RGD and ACW1947xxxx and ACW2032xxxx for the GLC-ZX-SM-RGD.
