Rack-Mount Installation 13
If you are installing the switch in a free-standing stack with other 3Com
equipment, arrange the smaller units above the larger ones. Do not have
a free-standing stack of more than four units.
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 3Com equipment, 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.
