    Hi,

     

    Can you please attach output of "request support information | no-more" command in a text file? We need to get the SFB HW version and Junos version.

     

    Thanks.

    Hi,

     

    It is a lot of information. Could I send the private message to you?

     

    Thank you very much.

    It looks like the complete RSI output might be too big of a file to attach to the post. Can you get the following output in a text file and attach to the post?

     

    show chassis hardware | no-more

    show version

    show configuration chassis | no-more

    show chassis alarms

     

    Also, can you try this command to bringup the SFB -

    request chassis sfb slot 0 online

     

    After entering command monitor the output of chassisd logs usign this command -

     

    monitor start chassisd

     

    Please also provide the chassisd logs after entering the command.

    Hi,

     

    From data you have provided, I see the chassis has 4 SFB cards installed, all are offline. I cannot determine the hardware model becasue they are not listed in the hardware output. Are these SFB boards or SFB 2 boards? Have these cards ever come online on this chassis? If yes, then what made them go offline?

     

    Could you also provide the following command output -

     

    request pfe execute command "show syslog messages" target spmb0 | no-more

    request pfe execute command "show nvram" target spmb0 | no-more

    show chassis environment | no-more

    show chassis fabric summary extended | no-more

    show chassis fabric degradation| no-more

    show chassis fpc

    show chassis fpc errros

    show log messages |no-more << Preferrably from the time when issue started.

    show chassis power

    show log inventory

     

    If the FPCs are currently powered on, please power them off and then re-seat one of the SFB's and provide the chassisd logs.

     

    Thanks for your patience!

    Hi,

     

    These cards have ever come online on this chassis. I don't know what made them go offline.

    show log messages |no-more << Preferably from the time when the issue started. -

    I don't know when and I already rebooted the node before.

    Re-seat the SFB means re-seat the RE, right? I'm going to do on Tuesday.

     

    Thank you very much.

    Hi,

     

    Did you get a chance to re-seat the SFB cards? I meant the fabric cards in the middle cage of the chassis, see the attached image for reference. The prcocedure is listed here -

     

    https://www.juniper.net/documentation/en_US/release-independent/junos/topics/task/installation/remove-mx2010-sfb.html

     

    What we need to make sure is that when the SFB card is re-seated, there is an entry in inventory logs, show chassis hardware output and gather output of "show chassis environment sfb". Even

     

    request pfe execute command "show jspec client" target spmb0 | no-more

    request pfe execute command "show chassis commands" target spmb0 | no-more

     

    Since in this case, none of the SFB cards is slots 0 to 4 are coming online, it is pointing to an Hardware issue with the Control Board to me.

     

    The SPMB manages FRUs & programs SFB's via PCIe. In this case, the PCIE  switch link between SPMB & SFB5 is down which prevents the SFB from coming online & getting the links trained, reporting failed ASICs.
    Please consider having the CB-RE FRU replaced.

    Hi,

     

    I found the root cause. I tried to upgrade to Junos: 16, it solved. Man LOL

     

    > show chassis hardware | match SFB
    SFB 0            REV 11   711-052892   CGJ3190          Switch Fabric Board 2
    SFB 1            REV 11   711-052892   CGG5294          Switch Fabric Board 2
    SFB 2            REV 11   711-052892   CGD5125          Switch Fabric Board 2
    SFB 3            REV 11   711-052892   CGJ2031          Switch Fabric Board 2

     

    Thank you very much.

    Hi,

     

    Thanks for the update, glad the issue is resolved. Just FYI -
    Junos 15.1F5 is required for SFB2 model, hence I had asked earlier whether the SFB model is SFB2.
