Smartrack User Manual
4.2.2 Planning an island installation
Smartracks may be mounted back to back, either in an island, or, with
one end of each bay against a wall, in a peninsula configuration.
On a solid floor, all wiring will normally be taken out through the top
wiring access ports. Where raised computer type flooring is used, some or
all of the wiring may enter through the base of the racks.
Note that the 'keyhole' fixing positions in the back of each rack must be
used in back-to-back installations, to provide stability. Use M6 nuts and
bolts to fix back-to-back racks together.
A knockout panel is provided in the centre of Smartrack's rear panel,
which may be removed if interwiring between back-to-back racks is
required. If using the knockout panels, use a grommet strip around the
inside edges to prevent chafing.
4.3. Wall fixings
Each Smartrack weighs between 75-85kg, depending on version used, and is
fixed to the wall at four points. Making an allowance for cable of 20-25kg per
rack, this means that each fixing has to support no more than 30kg. The actual
fixing used will depend very much on the wall material and condition, but on a
brick or concrete wall, 50 x 5mm woodscrews, used in conjunction with correctly
installed plastic wall plugs, should be more than sufficient.
On uneven surfaces, it may be necessary to mount 50 x 50mm wooden battens
to the wall, and fix the Smartracks to the battens. In this case, ensure that the bat-
ten fixings are sufficient to take the total weight of all the Smartracks to be so
mounted.
Having marked out the wall, drill, plug and fit mounting screws, protruding about
20mm from the wall.
4.4. Assembly and mounting
a) If the bottom Smartrack in a stack will stand on the floor, fit the four plastic
feet provided by screwing them up into the threaded inserts on the base of
the rack.
