Placing Units On Top Of Each Other; Stacking Units - 3Com 3C17203 Getting Started Manual

Placing Units On
Top of Each Other

Stacking 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
■
Using the Expansion Module slot at the rear of the Switch, you can stack
Switch units together in two ways:
The SuperStack 3 Switch Cascade Stacking Kit (3C17227) consists of
■
two Cascade Modules and a Cascade Cable. This kit allows you to
connect two Switch 4400 units together.
The SuperStack 3 Cascade Extender Kit (3C17228) consists of one
■
Cascade Module, one Cascade Cable and one Cascade Extender Unit.
This kit allows you to connect any of the combinations of Switch 4400
units shown in "Stacking Units"
Kit enables you to add one additional Switch to your stack.
For more information contact your supplier, and refer to the user
documentation that accompanies these Cascade Kits.
CAUTION: The SuperStack 3 Switch 4400 SE cannot be stacked with
non-SE Switches unless you are running the 4400 enhanced feature set.
