8 AT-9900 Series Switch
How to Install the Switch
Warning All AC and DC versions of this equipment must be earthed.
The switch is heavier at the rear than at the front. Therefore, to fully support
the switch in a rack we recommended that you use the supplied 19-inch
rack-mount kit. Using this kit is especially critical if the front mounting flange on
the rack is easily deformed, or the switch is installed in areas subject to shocks
such as earth tremors or heavy vibrations.
Prepare to install the switch
1. Read the safety information
Read the safety information included in this Quick Install Guide. This Quick
Install Guide is also on the Documentation and Tools CD-ROM and you can
download a copy from http:// www.alliedtelesyn.co.nz/support.
2. Gather the tools and equipment you will need
You will need a Phillips #2 screwdriver and cage nuts to attach the brackets
to your rack. Cage nuts are not supplied.
To install a switch with a DC power supply unit, you will need an
appropriate DC power source, DC supply cable, ring connectors, and a
crimp tool.
3. Choose a suitable operating location
Follow the guidelines described in “Selecting a Site” on page 7 to choose a
suitable location.
You can install the switch either in a 19-inch rack, on a flat bench, or against
a wall.
4. Unpack the switch
Verify the package contents. If any items are damaged or missing, contact
your authorised distributor or reseller.
