Stacking Up To Four
Units
You can stack up to four Switch units with a single SuperStack II Switch
Matrix Module and the appropriate number of Matrix Cables.
You only need one Matrix Module for each stack.
To stack up to four Switch units:
1
Power-off all the units.
2
Arrange the 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 25. When positioning the units, note that Matrix Cables
are 1m (3.28ft) long.
3
Install the Matrix Module into one of the 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.
4
Connect the Matrix Cables, as shown in Figure 9
:
a
Connect a Matrix Cable to the port marked Unit 1 on the Matrix
Module. Connect the other end of this cable to the matrix port of the
Switch that contains the Matrix Module.
b
Connect a second Matrix Cable to the port marked Unit 2 on the
Matrix Module. Connect the other end of this cable to the matrix port
of the second Switch.
c
Repeat steps
a
and
b
for any additional Switch units.
