Installing the Switch
You can install the switch on a level surface, such as a desktop or bench, or in a
standard 19-inch rack. The switch is heavier at the rear than at the front.
Therefore use the brackets supplied with the switch when rack-mounting
because they are designed to fully support the weight.
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.alliedtelesis.com/support/
software .
■ 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:
• Phillips # 2 screwdriver to loosen the blanking plate, if any
• 4 sets of rack-mount screws and nuts, and a suitable screwdriver
To install a DC version of the PSU, you need an appropriate DC power
source, DC supply cable, ring connectors, and a crimp tool.
■ Prepare the cabinet in a suitable location
Follow guidelines described in “Selecting a Site” on page 5 to choose an
appropriate location and modify the rack as necessary.
■ Because the switch is deep, we recommend two people mount the switch in
the rack and tighten the screws.
■ If you have an optional expansion module for the AT-9924Ts or x900-24X
switches, install it in the switch first.
Refer to the Expansion Module Installation Guide for the x900-24X Series Switch
for details.
Warning Both AC and DC versions of this equipment must be earthed through
the power cables provided.
