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 mixing a variety of 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 F12/F24 and Switch E12/E24 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. Contact
your supplier for details.
■
The Expansion Module slot at the rear of the Switch allows you to
install a Matrix Module. The Matrix Module provides four ports and
allows you to interconnect up to four Switch units using Matrix
Cables.
ATTENTION: While power is on, a unit may reset if another unit is
connected back-to-back using a matrix cable; or a stack may reset if
another unit is added to the stack.
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 32. 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
