How To Stack Units

If the Switch units are free-standing, up to eight units can be placed one
on top of the other. If you are mixing a variety of SuperStack
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.
Switch 4400 units can be stacked together and then treated as a single
manageable unit with one IP address. Any combination of 24-port and
48-port units is allowed in a single stack, as long as the total number of
front panel ports does not exceed the limit of 192 ports. The following
combinations are allowed:
4 x 48-port Switches
■
3 x 48-port Switches and 2 x 24-port Switches
■
2 x 48-port Switches and 4 x 24-port Switches
■
1 x 48-port Switch and 6 x 24-port Switches
■
8 x 24-port Switches
■
The SuperStack 3 Switch 4400 SE can only be stacked with non-SE
Switches if it has been upgraded using the Switch 4400 SE Enhanced
Software Upgrade (3C17207). An upgraded Switch 4400 SE cannot be
stacked with a normal Switch 4400 SE.
To stack two Switch 4400 units you will need to order the SuperStack 3
Switch Cascade Stacking Kit (3C17227). The kit consists of two Cascade
Modules and a Cascade Cable. Both Switches must have an unused
expansion slot to allow a Cascade Module to be fitted.
