Guidelines
Ensure that the rack complies with one of these standards:
A 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document
number EIA-310–D) published by the Electronics Industry Association (
Ensure that the rack rails are spaced widely enough to accommodate the switch chassis' external
dimensions . The outer edges of the front-mounting brackets extend the width of the chassis to
19 in. (48.2 cm).
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 of a rack is supplied
with each switch. For mounting the switch on four posts of a rack or cabinet, you can
order a four-post rack-mount kit separately.
