Part Number

WS-C3508G-XL-EN

800-06475-01

WS-C3512-XL-EN

800-05369-02

Switches with incorrect LEDs were manufactured within the Date Code range of 0449 through 0451. See: How to Identify Date Codes.

WS-C3524-XL-EN

800-05400-02

Switches with incorrect LEDs were manufactured within the Date Code range of 0449 through 0451. See: How to Identify Date Codes.

WS-C3524-PWR-XL-EN

800-06367-01

Switches with incorrect LEDs were manufactured within the Date Code range of 0449 through 0451. See: How to Identify Date Codes.

Problem Description

The wrong LEDs were installed in between 1000 and 1500 boards, which were later installed in switches. The incorrect LEDs produce a red light instead of amber when reporting a status mode that is normally reported with an amber light.

The switch features and functions are not affected by the incorrect LEDs and work normally.

Problem Symptoms

The incorrect LEDs produce a Red light instead of Amber:

Workaround/Solution

Replace affected units using the normal return materials authorization (RMA) process.

How To Identify Hardware Levels

Switches with the following Date Codes may have the incorrect LEDs installed:

  • FAA0449

  • FAA0450

  • FAA0451

See the section below on How to Identify Date Codes for further information.

How To Identify Date Codes

Date Codes are integrated into the first seven characters of an eleven-character System Serial Number: FAA0433A275. Date Codes are used to identify the specific time and place a switch was manufactured.

The first three letters are important because these represent the specific manufacturing location. In the following System Serial Numbers:

  • FAB0433A275

  • FAA0433A275

the switch with the FAB SSN was manufactured at a different location than the FAA switch, but during the same year and week (0433). The four subsequent numbers are the year (04) and the week (33) when the switch was manufactured. In the following System Serial Numbers:

  • FAA0430A275

  • FAA0433A275

the switch with the 0430 year and week code was made at the same location and during the same year, but on a different week from the switch with the 0433 year and week code.

Where to Find Serial Numbers

Serial Numbers can be found on

  • The packout box

  • The back of the switch

    If the switch is already installed in a network:

  • Telnet to the unit, or establish a direct connection to the switch console. The following switch information will appear, including the System Serial Number.

           Enterprise Edition Software
           Ethernet Address: 00-01-42-68-1D-40

           PCA Serial Number: FAA044933PS

            System Serial Number: FAA0449W1EE
           Power Supply S/N: APQ034704ZC
           PCB Serial Number: FAA044933PS,73-3121-04

    Another method is to type the show version command when you telnet into a 3500. A list of information will appear. You can find the serial number at the bottom of the screen:

           ..........Power supply part number: 34-0851-02
           Motherboard serial number: FAA03319K94
           Power supply serial number: NONE
           Model revision number: A0
           Model number: WS-C3512-XL-EN
           System serial number: FAA0449E04Q
           Configuration register is 0xF....................
    

    Another command you can use is the show version | include serial number command. (The | is the bar symbol on the keyboard above the Enter key.) This displays the following information:

           Motherboard serial number: FAA04499K94
           Power supply serial number: NONE
           System serial number: FAA0449E04Q
    

    Use the Date Code to determine if switch is within the Date Code range. (see the section above on How to Identify Date Codes)
