Figure 9 A stack of two units

Stacking Multiple You can connect up to four Switch units to form a stack. If you connect Units more than two units, you need a SuperStack II Switch Matrix Module and

the appropriate number of Matrix Cables.

You only need one Matrix Module for each stack.

To stack multiple Switch units:

1Arrange your Switch units as required. They can be rack-mounted or free-standing; if you choose to have them free-standing, remember to position the rubber feet as detailed in “Placing Units On Top of Each Other” on page 27. When positioning Switch units, note that Matrix Cables are 1m (3.28ft) long.

2Install the Matrix Module into one of the Switch units. You can find instructions for doing this in the documentation that accompanies the Matrix Module. We recommend that for ease of configuration, the Matrix Module should be installed in the bottom Switch of your stack.
