Selecting a Site

The switch can be installed in a standard 19-inch rack or on a level surface such

as a desktop or bench. 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 0-50º C (32-122º F) and a

humidity range of 5-95% non-condensing.

■

Has a reliable and earthed (grounded) power supply circuit, 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. See the AT-8800

Series Hardware Reference for cable length specifications.

Installing the Switch

This equipment must be earthed.

Follow these steps to install the switch:

Read the safety information

For safety information, see the Safety and Statutory Information booklet. A

copy of this booklet is supplied with each switch, and can also be found on

the Documentation and Tools CD-ROM or at

software.

Gather the tools and equipment you will need

If the switch is to be connected to a redundant power supply, you will need

a redundant power supply unit and cable (see step 8).

To install the switch in a rack you will need screws and cage nuts to attach

the brackets to your rack. These are supplied with the switch.

Choose a suitable site for the switch

Either a flat surface or 19 inch rack.

Unpack the switch

Verify the package contents. If any items are damaged or missing, contact

your sales representative.
