Installing a Stacking Transceiver
The stacking transceiver must be installed in the port 25 slot. It should be inserted before any of the
systems in the stack are powered on.
Slide the SFP transceiver into the SFP transceiver slot until it clicks into place. To remove, pull on the tab
at the bottom of the front of the transceiver.
Connecting Switches in a Stack Using a Transceiver
To connect up to eight switches in a stack, perform the following steps:
1. Install SFP stacking transceivers into the port 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 the Rx port on the bottom unit (stacking up to 8 units).
5. Complete the stack connections by plugging one end of a stack cable into the Tx port on the bottom
unit and the other end into the Rx port on the top unit.
