Rackmount Installation
Included with the Pro-Switch/8F are brackets allowing the switch to be
mounted in a standard EIA-sized, 19-inch rack. The Switch can be placed
in a wiring closet with other equipment.
Per form the following steps to rack mount the switch:
A. Align one bracket with the holes on one side of the switch and secure
it with the small bracket screws. Then attach the remaining bracket to
the other side of the Switch.
B. After attaching both mounting brackets, position the Pro-Switch/8F in
the rack by lining up the holes in the brackets with the appropriate
holes on the rack. Secure the Switch to the rack with a screwdriver
and the larger rack-mounting screws.
Note: For proper ventilation, allow at least 4” ( 10 cm ) of clearance at the front
and 3.4” ( 8 cm ) at the back of the Switch. This is especially impor tant for
an enclosed rack installation.
