Connecting Switches in a Stack 3

You can form a stack containing up to four MIL-SM4804G units. To connect switches in a stack, perform the following steps:

1.Enable the stacking ports on each unit (i.e., the Stack button pushed out)

Note: Pressing the Stack button during normal operation will cause the system to reboot.

2.Plug one end of a stack cable (ordered separately) into the Down (left) port of the top unit.

3.Plug the other end of the stack cable into the Up (right) port of the next unit.

4.Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the Down port on the top unit and ending at the Up port on the bottom unit (stacking up to 4 units).

5.(Optional) To form a wrap-around topology, plug one end of a stack cable into the Down port on the bottom unit and the other end into the Up port on the top unit.
