Chapter 2 Preparing Your Site for Installation
Site Planning
Allow the following clearances for normal system maintenance:
•
At the back of the chassis for maintenance—To 4 ft (91.44 cm to 121.92 cm)
•
At the back of the chassis for airflow obstructions—At least 4 inches (7.6 cm)
•
In the front of the chassis for maintenance—3 to 4 ft (91.44 cm to 121.92 cm)
•
In the front of the chassis for airflow obstructions—At least 4 inches (7.6 cm)
To avoid problems during installation and ongoing operation, follow these general precautions when you
plan the equipment locations and connections:
•
Use the show environment all command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and creates reports on any occurrences. If warning messages are displayed, take
immediate action to identify the cause and correct the problem.
•
Keep the Cisco RFGW-10 UEQAM off of the floor and out of areas that collect dust.
•
Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
Locating for Proper Airflow
Ensure the location of the Cisco RFGW-10 UEQAM has enough airflow to keep the system operating
within the environmental characteristics and the air temperature is sufficient to compensate for the heat
dissipated by the system.
Avoid locating the Cisco RFGW-10 UEQAM in a location in which the chassis air intake vents could
draw in the exhaust air from adjacent equipment. Consider how the air flows through the Cisco
RFGW-10 UEQAM. The Cisco RFGW-10 UEQAM airflow direction is front to back with ambient air
drawn in from the venting located on the chassis front sides.
Site Planning Checklist
Table 2-7 is provided to help you perform and account for all the site planning tasks.

Site Planning Requirements Yes/No
The site meets the environmental requirements.
The site air conditioning system can compensate for the heat dissipation of the Cisco RFGW-10 UEQAM.
The floor space that the Cisco RFGW-10 UEQAM occupy can support the weight of the system.
Electrical service to the site complies with the requirements.
The electrical circuit servicing the Cisco RFGW-10 UEQAM complies with the requirements.
Consideration has been given to the console port wiring, and limitations of the cabling involved, according to
TIA/EIA-232F.
The Cisco RFGW-10 UEQAM Ethernet cabling distances are within limitations.
The equipment rack in which you plan to install the Cisco RFGW-10 UEQAM chassis complies with
requirements.
Careful consideration has be given to safety, ease of maintenance, and proper airflow in selecting the location
of the rack.
