Preparing The Floor For A Seismic Cabinet - Nortel Multiservice Switch 7400 Installation & Maintenance

Preparing the floor for a seismic cabinet

Prepare the floor for a seismic cabinet using one of the seismic anchoring kits.
Or, if you do not require seismic protection, you can anchor the seismic
cabinet to stabilize the cabinet and prevent it from tipping over.

Action
After you complete a floor plan, mark the floor to show the positions of all
cabinets and other equipment. The figure
(page 340) shows the footprint for a seismic cabinet.
Mark any cutouts for seismic anchoring brackets or stabilization anchors.
The stabilization anchor hardware swivels 360 degrees. Therefore, you can
place a stabilization anchor anywhere within the 2 3/8 in. (6 cm) radius of a
levelling foot.
For easy access to the stabilization anchor hardware, position the
stabilization anchors outside the cabinet footprint. For multiple cabinet
installations, position the anchors inside the cabinet footprint so that the
stabilization anchors do not obstruct materials around the cabinets.
Mark any cutouts for routing cables under a raised floor. Cutouts for cables
must be directly beneath the smaller grille at the base of the cabinet. See
the figure Seismic cabinet footprint (page
Drill all anchoring holes if you have a raised floor. If you do not have a raised
floor, drill all holes during installation.
Clean each hole thoroughly with a vacuum cleaner.
Cover the holes with acetate tape to prevent them from being filled with
debris.
Cut out any holes for routing cables under a raised floor. A 5.0 in. by 14 in.
(12 cm by 35 cm) floor cutout can accommodate all cables from a fully
configured cabinet.
Smooth any sharp edges on the cutouts that could damage cables.
