Rack Requirement Guidelines
Rack size and strength
■Ensure that the rack complies with one of these standards:
■A
■A
The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the switch's mounting brackets, which measure 19 in. (48.2 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.
■Ensure that the rack is one of the following standard lengths:
■23.62 in. (600 mm)
■30 in. (762 mm)
■21.5 in. (546 mm)
Rack connection to building structure
■Ensure that the rack rails are spaced widely enough to accommodate the switch chassis' external dimensions of 1.75 in. (4.45 cm) height, 17.5 in. (44.5 cm) width, and 10.5 in. (26.7 cm) depth. The outer edges of the
The spacing of rails and adjacent racks must also allow for the clearances around the switch and rack.
■The rack must be strong enough to support the weight of the switch.
■Ensure that the spacing of rails and adjacent racks allows for the proper clearance around the switch and rack.
■Secure the rack to the building structure.
■If earthquakes are a possibility in your geographical area, secure the rack to the floor.
■Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.
One pair of mounting brackets for mounting the switch on two posts is supplied with each switch. You can order a
