Rack Requirements for EX4300 Switches
You can mount the switch on two-post racks or four-post racks.
Rack requirements consist of:
•
Rack type
•
Mounting bracket hole spacing
•
Rack size and strength
•
Rack connection to the building structure
Table 59 on page 91
provides the rack requirements and specifications for the switch.
Table 59: Rack Requirements and Specifications for the Switch
Guidelines
Rack Requirement
Use a two-post rack or a four-post rack. You can mount the switch on any two-post or
four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or
4.45 cm) increments and that meets the size and strength requirements to support the
weight.
A U is the standard rack unit defined in
Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Industry Association
(
http://www.eia.org
) .
Rack type
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the
switch can be mounted in any rack that provides holes spaced at that distance.
Mounting bracket hole spacing
•
Ensure that the rack complies with the size and strength standards of a 19-in. rack as
defined in
Cabinets, Racks, Panels, and Associated Equipment
(document number
EIA-310–D) published by the Electronics Industry Association (
http://www.eia.org
) .
•
Ensure that the rack rails are spaced widely enough to accommodate the external
dimensions of the switch chassis. The outer edges of the front mount 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 provides for proper clearance
around the switch and rack.
Rack size and strength
•
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.
Rack connection to building structure
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.
