Table Top Mounting the ONline Concentrator
You can set the ONline Con centrator directly on a tab le top or shelf that
can support at least 100 pounds (45 kg). A fully loaded concentrator
weighs about 75 lb s (3 4 kg). 3Com recommends yo u s et t he u n it on top of
the ONline cable tray as the cable tray provides a central area for cable
management and provides the req uired 1 3/4" (4.5 cm) of clearance for
sufficient air flow. Regardless of whether the cable tray is used or not, the
four (4) rubber feet must remain on the bottom o f the unit.
If the cable tray is used, place the ONline unit on top of the cable tray and
insert the rubber feet from the unit into the holes in the cable tray, which
stabilizes the unit on the tray.
If the cable tray is not use d, place the unit on the table or shelf.
