2530-48G doesn't recognise SFP+ direct attach cable

    Hi,

     

    Just started configuring some new 2530-48G (J9281B) switches and ran into the following problem.

     

    Together with the switches we ordered a few SFP+ direct attach cables (J9775A) as they were listed as an accessory.

     

    When the interfaces refused to come up, I looked at the logs and saw the following entries:

     

    W 01/01/90 00:00:19 00536 FFI: port 49 Transceiver type not supported in this
    port.
    W 01/01/90 00:00:19 00536 FFI: port 50 Transceiver type not supported in this
    port.

     

    As expected the following command doesn't return anything:

     

    switch1# show tech transceivers

    transceivers

    Transceiver Technical Information:
    Port # | Type | Prod # | Serial # | Part #
    -------+-----------+------------+------------------+----------

     


    === The command has completed successfully. ===

     

    How come these cables don't work, when HP lists these as compatible on the product page of the switch? 

     

    The cable is listed on the following page, under the tab services and options.

     

    http://www8.hp.com/be/nl/products/networking-switches/product-detail.html?oid=5333809#!tab=oas

     

    I haven't upgraded the firmware yet, as it should work regardless of version.

     

    switch1# show version

    Anyone got an idea?

    In the meantime I've upgrade the firmware to the latest one to see if it makes a difference.

     

    switch1# show version
    Image stamp:
    /ws/swbuildm/rel_orlando_qaoff/code/build/lakes(swbuildm_rel_orlando_qaoff_rel_
    orlando)
    Jan 30 2015 18:50:46
    YA.15.16.0006
    72
    Boot Image: Primary

     

    As a result, the sfp cable still doesn't work, but now I get more info from the show tech transceivers command:

     

    switch1# show tech transceivers

    transceivers

    Transceiver Technical Information:
    Port # | Type | Prod # | Serial # | Part #
    -------+-----------+------------+------------------+----------
    49 | ?? | ?? | unsupported | 8121-1300
    50 | ?? | ?? | unsupported | 8121-1300


    The following transceivers have extra information:
    Port # Message
    -------- -------------------------------------
    Port 49 Transceiver type not supported in this port.
    Port 50 Transceiver type not supported in this port.

     


    === The command has completed successfully. ===

     

    All suggestions are welcome.

    The switch you have doesn't support 10Gig and the DAC is only 10Gig. There are 4 versions of the 2530 that do support 10Gig and that DAC:


    HP 2530-48G-PoE+-2SFP+ Switch (J9853A)
    HP 2530-48G-2SFP+ Switch (J9855A)
    HP 2530-24G-PoE+-2SFP+ Switch (J9854A)
    HP 2530-24G-2SFP+ Switch (J9856A)

     

    SFP = 1Gig
    SFP+ = 10Gig

     

    To use the 4 SFP ports on your switch, you need a transceiver. There is one that will give you another RJ45 for GigT and then options for fiber cables. So if you want the DAC type functionality, you would need 2 RJ45 transceivers and a Cat5,6,6a, or 7 cable.

     

    X121 1G SFP RJ45 Transceiver (J8177C)
    X121 1G SFP LC SX Transceiver (J4858C)
    X121 1G SFP LC LX Transceiver (J4858C)
    X121 1G SFP LC LH Transceiver (J4858C)
    X122 1G SFP LC BX-D Transceiver (J9142B) This is special and only uses one fiber strand
    X122 1G SFP LC BX-D Transceiver (J9142B) This is for the other end of the transceiver above

    For 100Mb - X111 100M SFP LC FX Transceiver (J9045C)

     

    By the way, there is a really cool tool online that will help configure a switch: http://h17007.www1.hp.com/us/en/networking/products/configurator/index.aspx

     

    Hope this helps.
