Installation and Safety Guide

Installing the Switch
Ports on the switch are suitable only for connections within buildings (intra-
building) and with cables unexposed to the outside.
You can install the switch on a level surface, such as a desktop or bench, or in a
standard 19-inch rack. Some switches are heavier at the rear than at the front.
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
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.
• Rack-mount screws and nuts, and a suitable screwdriver. The
SwitchBlade x908 requires eight sets of screws and nuts. All other
switches required four sets.
• For DC installations, you need an appropriate DC power source, DC
supply cable, ring connectors, and a crimp tool for screw terminal style
connectors or appropriate connectors for the PSU model.
■Prepare the cabinet in a suitable location
Follow guidelines described in “Selecting a Site” on page 6 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.

Preparation for NEBS

For Network Equipment Building System (NEBS) installations of the x900-24XT-N,
do the following to ensure rack-mounted installations are earthed:
■Remove non-conductive coatings, such as lacquer and enamel, from the rack
rail where hardware will contact it. Remove coatings from unplated
connectors, braided strap, and bus bars, and bring them to a bright finish.
Coat them with an antioxidant before connecting them. During installation,
thread-forming screws with star washers may be used for this purpose.
