reboot.

2.Plug one end of a stack cable into the “Up” (right) port of the top unit.

3.Plug the other end of the stack cable into the “Down” (left) port of the next unit.

4.Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the “Up” port on the top unit and ending at the “Down” port on the bottom unit (stacking up to 8 units).

5.For ring-topology stacking, complete the connections by plugging one end of a stack cable into the Up port on the bottom unit and the other end into the Down port on the top unit.

6.Select the Master unit in the stack by pressing in the Master button on only oneof 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.

Connecting to a Power Source

To connect a switch to a power source:

1.Insert the power cable plug directly into the AC receptacle located at the back of the switch.
