Re: how to cable for stacking 2910al

  1. Plan what you intend to do!
  2. Plug it all all in (modules + cables) [maybe not the cables yet- depends on what your network looks like --> spanning tree and loop issues]
  3. check the config - you should now have a new port (A1) in each switch in VLAN1
  4. Choose your main VLAN and untag that on A1 on each switch
  5. Tag all the other VLANs on A1 on each switch that need to communicate
  6. check spanning tree, especially if you have those 8 switches in a big loop

How do I cable the switches together, the interconnect kit j9165a has two modules that plug into the back say module a is on the left and module b on right
