6100 switch SM transceiver "waiting for link"

  • 1.  6100 switch SM transceiver "waiting for link"

    Posted Apr 19, 2024 10:51 AM


    I have a 6100 (JL678A) switch that I try to connect to a singlemode uplink using a J9151D (part number 1990-3883) transceiver.

    Unfortunately the status remains "waiting for link" when I plug in the cable.

    "show int brief" says:

    "1/1/26         1       access 10G-LR           yes     down    Waiting for link        --      --"

     The log says:

    "Transceiver 10G-LR inserted in 1/1/26 is supported. An HPE pluggable module that is supported in this interface"

    My firmware version is PL.10.12.1000.

    I have another device (a custom built machine) that works with this transceiver and cable.

    I did try a few things (some out of desperation):

    • reboot the switch
    • allow unsupported transceiver
    • try a second, identical transceiver
    • change MTU from 1500 to 9000
    • change speed

    Any idea what could be wrong?

    Kind regards,

    The J9151D 1990-3883 is not documented in the  AOS-S and AOS-CX Transceiver Guide Edition 16.


    • Distance between switch and peer device?
    • Peer device and transceiver type?
    • What type of cable is used?

    Note firmware 10.12.xxxx SSR go end-support 15 May 2024, please use the latest LSR release what is 10.13.1000 at this moment.
