    Hey Guys,

     

    I have one question, maybe you can answer it, i am pretty sure. I wanted to test some SFPs and DACs from Brocade. They didn't work with my 7210 controllers. I know that there is the compatibility list from Aruba.

     

    We are going to buy 4x 10G-Aruba-SFP and 4x 10G-Brocade SFP to connect the Controllers with our Brocade VCS-Fabric..

     

    This was the Message of the controller after checking the transceiver:

     

    DAC-Cable-10G:

    Module is SFP/SFP+
    Manufacturer        : BROCADE
    Part Number         : 58-1000026-01   , rev: A
    S/N                 : CAX109520000394
    Date Code           : 091224 Lot:
    Optional Signals    : LOS, Tx Disable
    Supported Modes     : 10GBASE-DAC-A, Copper Pigtail Connector
    Wavelength          : 1024 nm
    Cablelength         : 1m

     

    SFP-10G:

    Module is SFP/SFP+
    Manufacturer        : BROCADE
    Part Number         : 57-0000075-01   , rev: A
    S/N                 : AAA314133007311
    Date Code           : 140403 Lot:
    Optional Signals    : LOS, Tx Fault, Tx Disable
    Supported Modes     : 10GBASE-SR, LC Connector
    Wavelength          : 850 nm

     

    Question: What does the message mean? (I marked it red)

     

    Regards,

    Thomas

    Generally speaking, unsupported SFPs either work (link and pass traffic) or don't (uni-directional link, errors, doesn't pass traffic). It can be difficult to troubleshoot exactly why one doesn't work.

    Hi

     

    I'm not entirely sure about the error message, but LOS usually means loss of signal.

     

    I also believe that the TX disable is an indication that the transmitter is turned of, why i don't know. I would guess some kind of incompatibility, obviously :D

     

    Btw, TX means transmit, but i guess you knew that :D
