Note: The stacking transceiver must only be installed in the port 25 SFP
slot.
To connect up to eight switches in a stack, perform the following steps:
1. Install SFP stacking transceivers into the por t 25 slot for each switch
in the stack.
2. Plug one end of a stack cable into the Tx (top ) port of the top unit
3. Plug the other end of the stack cable into the Rx (bottom) port of the
next unit.
4. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain
starting at the Tx port on the top unit and ending at th e Rx port on the
bottom unit (stacking up to 8 units).
