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 to 40º C (32 to 104º F) and
a humidity range of 5 to 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 radios,
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-9800
Series Hardware Reference for cable length specifications
Installing the Switch
This equipment must be earthed.
Follow these steps to install the switch:
1.
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 www.alliedtelesyn.co.nz/
support/at9800/.
2.
Gather the tools and equipment you will need
If installing a DC version of the switch, you will need a DC power source,
DC supply cable, and ring connectors (see step 8).
If the switch is to be connected to a redundant power supply, you will need
a redundant power supply unit and cable (see step 10).
3.
Choose a suitable site for the switch
Either a flat surface or 19 inch rack.
4.
Unpack the switch
Verify the package contents. If any items are damaged or missing, contact
your sales representative.
