Preparing Your Site for Installation
Rack Selection Guidelines
The Cisco RFGW-10 UEQAM can be mounted in most two-post or four-post, 19-inch equipment racks
that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D
19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.
Caution
When mounting a chassis in any type of rack equipment, make certain the inlet air to the chassis does
not exceed 104°F (40°C).
The distance between the center lines of the mounting holes on the two mounting posts must be 18.31
inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is
suitable for most 19-inch equipment racks.
We recommend that you mount the Cisco RFGW-10 UEQAM in an equipment rack that includes the
necessary rack-mounting hardware, which is suitable for most 19-inch equipment racks.
Consider installing the Cisco RFGW-10 UEQAM in a rack with the following features:

Equipment Rack Guidelines
The placement of the rack can affect personnel safety, system maintenance, and the system ability to
operate within the environmental characteristics described in
Cisco RFGW-10 UEQAM by following the guidelines below.
Locating for Safety
If the Cisco RFGW-10 UEQAM is the heaviest or the only piece of equipment in the rack, consider
installing it at or near the bottom to ensure that the rack center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, consult the document
GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.
Locating for Easy Maintenance
Keep at least 3 feet of clear space in front and behind the rack. This space ensures that you can remove
the Cisco RFGW-10 UEQAM components and perform routine maintenance and upgrades easily.
Avoid installing the Cisco RFGW-10 UEQAM in a congested rack and consider how the routing of
cables from other pieces of equipment in the same rack could affect access to the routers cards.
The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent
overheating inside the chassis.
OL-16264-04
NEBS-compliant, 19-inch (48.3 cm) wide rack.
EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the
Cisco RFGW-10 UEQAM. If the rack that you plan to install the system in has metric-threaded rails,
you must provide your own metric mounting hardware.
Perforated top and open bottom for ventilation to prevent overheating.
Leveling feet for stability.
