Stacking Two Units

WITCH
Units in the Switch 1100/3300 family can be stacked together and then
treated as a single manageable unit with one IP address.
The Matrix Port on the rear of the Switch allows you to connect two
Switch units back-to-back. For this you need a Matrix Cable (part number
3C16965). Contact your supplier for details.
The Switches in a stack are numbered 1 to 4, from the bottom up, for
management purposes. The SuperStack II Switch 3300 MM will always be
identified as Unit 1 and should therefore be positioned at the bottom of
the stack.
You can stack two Switch units with a single Matrix Cable. To do this:
1 Power-off both 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
Other" on page 25. When positioning the units, note that Matrix Cables
are 1m (3.28ft) long.
3 Connect one end of the Matrix Cable to the Matrix Port of the top
Switch, and the other end to the Matrix Port of the lower Switch (See
Figure 8).
4 If you use the management software of the units:
Ensure that both units have the same version of management
software
Ensure that you re-configure the stack-wide features on both units
For more information about management software, see
Switch" on page 32.
