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.
Prerequisites
• Ensure your floor plan takes into consideration all of the information in
“Site preparation” (page 53).
Procedure steps
1 After you complete a floor plan, mark the floor to show the positions of all
cabinets and other equipment. The figure “Seismic cabinet footprint”
(page 324) shows the footprint for a seismic cabinet.
2 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.
3 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 324).
4 Drill all anchoring holes if you have a raised floor. If you do not have a
raised floor, drill all holes during installation.
5 Clean each hole thoroughly with a vacuum cleaner.
6 Cover the holes with acetate tape to prevent them from being filled with
debris.
7 Cut out any holes for routing cables under a raised floor. A 5 in. x 14 in.
(12 cm x 35 cm) floor cutout can accommodate all cables from a fully
configured cabinet.
8 Smooth any sharp edges on the cutouts that could damage cables.
