Stacking Units
Units in the Switch 1100/3300 family can be stacked together and then
treated as a single manageable unit with one IP address.
You can stack Switch units together in two ways:
■
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 Expansion Module slot at the rear of a Switch 1100/3300 allows
you to install a Matrix Module (part number 3C16960). The Matrix
Module provides four ports and allows you to interconnect up to four
Switch units using Matrix Cables.
Stacking Two Units 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 “Placing Units On Top of Each
Other” on page 25. When positioning the units, note that Matrix Cables
are 1m (3.28ft) long.
3
As shown in Figure 8, 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
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 “Managing the
Switch” on page 32.
