Connecting to the Stack’s Backplane
Plug one end of the provided stack cable in the “Down” port of the top unit and the
other end to the “Up” port of the next unit. Repeat this step 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 8 units).The VDSL Switch-VS2512A
supports a wrap-around stacking feature. If a connection is made between the
“Down” port of the bottom switch in the stack and the “Up” port of the top switch,
then all switches in the stack will remain connected, even if one fails.

Select the Master unit in the stack by pushing the push button in on the front of the
switch.
Note: Only one switch in the stack can act as Master.
