• Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with
mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992
standard.
• The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear
mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).
• Required clearances between the chassis and the edges of its rack or the interior of its cabinet are as
follows:
◦ 4.5 inches (11.4 cm) between the front of the chassis and the interior of the cabinet (required for
cabling).
◦ 3.0 inches (7.6 cm) between the rear of the chassis and the interior of the cabinet (required for
airflow in the cabinet if used).
◦ No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).
Additionally, you must have power receptacles located within reach of the power cords used with the switch.
Statement 1048

Rack Stabilization
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor
before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.
Warning
Clearance Requirements
You must provide the chassis with adequate clearance between the chassis and any other rack, device, or
structure so that you can properly install the chassis, route cables, provide airflow, and maintain the switch.
For the clearances required for an installation of this chassis in a four-post rack, see the following figure.
