Selecting a Site
Before you install the switch, review the following considerations about its
location.
■
AT-8948, x900-48FE, and AT-9900 switches require an ambient temperature
from 0º C to 50ºC (32º F to 122º F).
■
AT-9924Ts, x900-24X switches require an ambient temperature from 0º C to
40ºC (32º F to 104º F).
■
There should be adequate airflow around the switch and its vents.
■
The site should be dust-free and without moisture.
■
Humidity can be from 5% to 80% non-condensing.
■
You need a reliable and earthed (grounded) power supply source, preferably
dedicated and filtered.
■
Cabling must not be exposed to sources of electrical noise, such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■
Related network devices can be connected to the switch but cannot exceed
maximum cable lengths specified in the Hardware Reference.
■
You may need to remove doors to accommodate cords and cables.
■
Ensure easy access to the switch’s power and cable connections.
