    Hi all,

    Is there anything special to 'activate' 40G-ports on 6125XLG ?

    I want to connect 6125XLG #1 port FGE2/1/4 to 6125XLG #2 port FGE1/1/4
    Ports remain down, whatever the port config is.
    The reason is probably : transceivers are not seen.

    <PK5-SBY-BS-11>display transceiver interface FortyGigE 2/1/4
    The transceiver is absent.
    <PK5-SBY-BS-11>
    <PK5-SBY-BS-11>display transceiver interface
    FortyGigE1/1/1 transceiver information:
    The transceiver is absent.
    FortyGigE1/1/2 transceiver information:
    The transceiver is absent.
    FortyGigE1/1/3 transceiver information:
    The transceiver is absent.
    FortyGigE1/1/4 transceiver information:
    The transceiver is absent.
    FortyGigE2/1/1 transceiver information:
    The transceiver is absent.
    FortyGigE2/1/2 transceiver information:
    The transceiver is absent.
    FortyGigE2/1/3 transceiver information:
    The transceiver is absent.
    FortyGigE2/1/4 transceiver information:
    The transceiver is absent.
    ...

    Same issue with several transceivers, on different ports, on different 6125XLG switch.

    If I put the same transceiver (moved from 2/1/4) to one 5900AF-48G-4XG-2QSFP+ , it is reconized right away (even whit default port config + 'shutdown'):
    <CIT-PRE-SS-01>display transceiver interface FortyGigE 1/0/53
    FortyGigE1/0/53 transceiver information:
      Transceiver Type              : 40G_BASE_SR4_QSFP_PLUS
      Connector Type                : MPO
      Wavelength(nm)                : 850
      Transfer Distance(m)          : 100(OM3)
      Digital Diagnostic Monitoring : YES
      Vendor Name                   : HP
      Ordering Name                 : JG325B
    <CIT-PRE-SS-01>

    Transceivers are : HPE X140 40G QSFP+ MPO SR4 (JG325B)
    They are connected together with : HP 10m PremierFlex OM4 MPO/MPO 8 fibre Multi-Mode Optical Cable (QK729A)
    According to QuickSpecs 'HPE 6125XLG Ethernet Blade Switch', QSFP+ 'HPE X140 40G QSFP+ MPO SR4 Transceiver JG325B' are supported.

    Attached : picture of the QSFP+ used into the 6125XLG 

    Thanks!
