    Hi.

    I have a S2500 that also acts as our Primary Router and another S2500 that will be uplinked to the Router soon, in the same closet, though just as a standard switch.

    I just received some fiber to run as our backbone, so I plugged a SFP into a SFP port on the router and also on the second S2500, so they could then communicate. I wanted to test to see if I had to configure anything to get the fiber to work, once I ran it.

    I searched in vain for data on how to connect a fiber backbone, but all I could find was stuff on stacking, so I assume Aruba uses stacking when connecting a fiber backbone?

    Anyway, the problem is when I unplugged the SFP from the main router all ports on the router went black and the network was dead, though the router was still running.

    I plugged the SFP and fiber back in to the original ports and the router ports lit up and all is well.

    Problem is, I don't want the second S2500 to be connected to the router via that fiber.

    My main question is; How can I undo what I did?

    And, not as important, how do I uplink my two closets via fiber? Is it through stacking?

    Thank you!

    What physical interfaces did you use to connect the fiber?

    Hi Thanks for the response
    Here is what I have:

    Also, I just disabled the split detection via the GUI. Hopefully, that
    prevents the router from going dark on secondary shutdown.

    OK...so if port 1/3 is in use and active, that is acting as a stacking port on the Aruba switch.  Is port 0 or 1 avaialble?  If so, you can just use those as a normal switch interconnect/uplink like any other port on the switch.

    OK. Good.
    But, how do I remove these two switches from being stack members?
    My Router is reading as Secondary when I plug in the other S2500, but it
    then says Primary when I unplug the other switch. Wow, I dug myself in this
    time.lol

    Thanks for your help Seth!

    OK...on the second unit, issue this command after it's been removed from the stack...

     

    restore factory-default stacking

    You can also do this to use ports 1/2 and 1/3 as regular uplinks...this will remove them from being "stack" ports..

     

    delete stacking interface stack 1/2

    Thank you. I will issue that command to gladly get rid of them. But, how do
    I remove the switch from the stack? I deleted it from via the GUI, under
    configuration, stacking, but I can only communicate with it via the
    routers' IP.
    Sorry about this.

    No worries but I'd call into support and have them help you walk through this just so you gracefully exist this config with no unknown artifacts
