Connect network cabling.
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
®
3 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.
Creating an XRN
Distributed Fabric
Switch 4900 Series units and 3Com Switch 4050/4060 units can be
interconnected to create an XRN Distributed Fabric and then treated as a
single manageable unit with one IP address. A combination of any two of
these units is allowed to be interconnected.
