Guidelines
Ensure that the rack is 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 ) .
With the use of adapters or approved wing devices to narrow
the opening between the rails, the switch fits into a
600 mm-wide rack or cabinet , as defined in the four-part
Equipment Engineering (EE); European telecommunications
standard for equipment practice (document number ETSI EN
300 119) published by the European Telecommunications
Standards Institute ( http://www.etsi.org
The rack rails must be spaced widely enough to accommodate
the switch chassis's external dimensions (see Chassis Physical
Specifications of an EX9204 Switch, Chassis Physical
Specifications of an EX9208 Switch, and
Specifications of an EX9214 Switch" on page
of rails and adjacent racks must also allow for the clearances
around the switch and rack.
In general, a center-mount rack is preferable to a front-mount
rack because the more even distribution of weight in the
center-mount rack provides greater stability.
The chassis height of 14.0 in. (35.6 cm) is approximately 8 U.
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.
The rack must be strong enough to support the weight of the
fully configured switch (see Chassis Physical Specifications of
an EX9204 Switch, Chassis Physical Specifications of an EX9208
Switch, and "Chassis Physical Specifications of an EX9214
Switch" on page 13). . If you stack the rack with fully configured
switches, the rack must be capable of supporting the combined
weight.
The switch can be mounted in any rack that provides holes or hole
patterns spaced at 1 U (1.75 in.) increments. The mounting
brackets used to attach the chassis to a rack are designed to
fasten to holes spaced at those distances.
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.
