Anchoring to a raised floor
Additional information for installing the frame anchors
After a frame with two fully provisioned switches is completely installed with
all plug-ins and cabling, the footprint holds a worst-case weight of up to
725 kg (1,600 lbs). (No practical hardware setup would ever reach this weight
because it is based on having only 12-port DS3s in the switch plus every
possible optional heavier add-on.) For installations on a raised floor, the M12
anchor rods to help support the weight. Add an extra 18-mm (23/32-in.) nut
and a 10-cm (4-in.) wide by 0.5-cm (3/16-in.) thick washer to each M12
threaded rod before the rod is inserted in the floor holes. The nuts and washers
are to help support the weight from underneath the frame base. The washer
must be wide enough to span inches evenly beyond an anchor opening and
thick enough not to bend from the weight. Once the frame is anchored, the
optional nuts and washers cannot be added.
