Selecting a Site

The switch can be installed 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. When

installing 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 to 50º C (32 to 122º F) and

a humidity range of 5 to 95% 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.

■ will allow all related network devices to be connected to the switch

without exceeding maximum cable length limitations as specified in the

AT-8900 Series Hardware Reference.

■ will ensure that when a switch is mounted in a rack, it is mounted evenly

to prevent uneven mechanical loading of the rack.
