Preparing the floor for a Multiservice Switch cabinet
Prepare the floor for a Nortel Networks Multiservice Switch cabinet before
installing the cabinet.
Prerequisites
• Ensure that your floor plan takes into consideration all of the information
in
“Site preparation” (page 77).
Procedure steps
1 After the floor plan is complete, mark the floor to show the positions of all
cabinets (and associated anchoring holes and cutouts, if required) and
other equipment. The figure
“Multiservice Switch cabinet footprint”
(page 402) shows the footprint for a cabinet.
If you are installing one cabinet only, position the anchoring holes outside
the cabinet footprint. If you are installing more than one cabinet, position
the anchoring holes inside the cabinet footprint so that space around the
cabinets will not be obstructed. The anchoring hardware swivels 360
degrees.
To properly stabilize a cabinet, you must anchor at least two diagonal
corners of the cabinet. For increased safety, anchor all four corners.
Anchoring is mandatory for cabinets containing one device if the device is
in the top of the cabinet.
If you have a raised floor, drill the anchoring holes and cable cutouts
during the site preparation, before installation begins. If you have a non-
raised floor and are anchoring the cabinets, drill the anchoring holes as
part of the installation.
