Figure 3-7. Connecting Switches in a Stack
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 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.
6.Select the Master unit in the stack by pressing the push button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the stack will not function.
Note: The stacking feature requires that all stacking transceiver ports be connected and the switches powered on. If one stack link is not connected, the switches will operate as independent switches. If one of the switches in a stack is not powered on or fails, the remaining switches will operate as independent switches.
