Before You Start: Site Preparation
Before installing the C1048P port extender, make sure that your installation
site meets these requirements:
•
Clearance: There is adequate space in front of the PE so you can read the
LEDs, and adequate space around and behind the switch for cabling,
power connections, and ventilation. The AC power cord can reach from
the power outlet to the utility-panel connector. Airflow around the PE and
through the rear vents is unobstructed.
•
Cabling: The cabling is routed to avoid sources of electrical noise, such as
radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is safely away from other
devices that might damage the cables. If necessary, allow one RU space
between devices to provide room for cabling.
•
Temperature: The ambient temperature range around the operating PE is
from 0 to 45°C (32 to 113°F).
•
Altitude: Altitude at the installation site is below 10,000 feet (3048 m).
•
Humidity: The relative humidity around the operating PE is 8% to 85%
(non-condensing) with a maximum humidity gradation of 10% per hour.
•
Dust: The PE is installed in an environment as free as possible from dust
and foreign conductive material (such as metal flakes from construction
activities). Cooling mechanisms, such as fans and blowers in the switch,
can draw dust and other particles causing contaminant buildup inside the
chassis, which can result in system malfunction.
