Placing Units On
Top of Each Other
If the Switch units are free-standing, up to four units can be placed one
on top of the other. If you are mixing a variety of SuperStack II Switch and
Hub units, the smaller units must be positioned at the top.
If you are placing Switch units one on top of the other, you must use the
self-adhesive rubber pads supplied. Apply the pads to the underside of
each Switch, sticking one in the marked area at each corner. Place the
Switch units on top of each other, ensuring that the pads of the upper
unit line up with the recesses of the lower unit.
Stacking Units
Switch 1100 and 3300 units 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 the Switch 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
To stack two Switch units, you only need one Matrix Cable. The Switch
units 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” above. When positioning Switch
units, note that Matrix Cables are 1m (3.28ft) long.
