Allied Telesis AT-9900s manual Installing the Switch, Before you begin

AT-8900, AT-9900, AT-9900s Series Switches

Installing the Switch

The switch is heavier at the rear than at the front. Therefore, we recommend that you use the supplied 19-inch rack-mount kit to fully support the switch in a rack. Using this kit is essential if the front mounting flange on the rack is easily bent, or the switch is installed in areas subject to shocks such as earth tremors or heavy vibrations.

Before you begin

■Read the safety information.

For your well-being and that of the equipment, read the safety information in this document. You can also download this document from the Documentation and Tools CD-ROM or from www.alliedtelesyn.com

■Verify the package contents if you have not already done so.

See “Package Contents” on page 4. If any items are damaged or missing, contact your authorised distributor or reseller.

■Gather necessary tools and equipment.

You need a Phillips #2 screwdriver to adjust the retaining screws on the power supply unit (PSU) or fan-only module (FOM).

To install a DC version of the PSU, you need an appropriate DC power source, DC supply cable, ring connectors, and a crimp tool.

■Choose a suitable operating location.

Follow the guidelines described in “Selecting a Site” on page 5 to choose a suitable location.

■Decide whether two people are needed to mount the switch into the rack and tighten the screws (step 7).

■If you have an optional expansion module for the AT-9900s Series switch, install it in the switch first.

Refer to the Expansion Module Installation Guide for the AT-9900s Series Switch for details.

Warning Both AC and DC versions of this equipment must be earthed.
