Quick Install Guide 7
Selecting a Site
You can install the switch in a standard 19-inch rack, on a level surface such as a
desktop or bench, or against a wall using the optional wall-mount kit. How to
install the the switch using the 19-inch rack-mount kit is described below. How
to install the switch using the wall-mount kit is described in the AT-9900 Series
Hardware Reference.
When you install the switch, choose a site that:
■ allows adequate airflow around the switch and its vents.
■ is free of dust and moisture.
■ will maintain an ambient temperature range of 0 º C to 50º C
(32º F to 122º F) and a humidity range of 5% to 80% non-condensing.
■ has a reliable and earthed (grounded) power supply, preferably dedicated
and filtered.
■ does not expose cabling to sources of electrical noise such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■ allows easy access to the switch’s power and cable connections.
■ allows all related network devices to be connected to the switch without
exceeding maximum cable length limitations as specified in the AT-9900
Series Hardware Reference.
■ ensures that when the switch is mounted in a rack, the switch is mounted
evenly to prevent uneven mechanical loading of the rack.
