Models Covered by this Guide
■XEM-1XP provides a single XFP port
■XEM-12S provides 12 SFP ports
■XEM-12T and XEM-12T-N provide 12 10/100/1000Mbps RJ-45 ports
Package Contents
One warranty card and this Installation Guide are included with each expansion
module. Contact your sales representative if either is damaged or missing.
Overview
Two front bays in the x900-24X Series switch allow quick and easy installation of
optional expansion modules (XEMs). These modules enable economical
combinations of speed and port density with the x900-24X Series gigabit link
aggregation switch.
For example, add one 10GbE expansion module to provide a single high-speed,
high capacity fiber connection; add a second 10GbE module for redundancy or
as bandwidth needs increase. Add one or two 12-port RJ-45 copper expansion
modules to provide maximum gigabit Ethernet port density in a compact 1RU
chassis. For flexible port options, add one or two 12-port SFP expansion
modules to aggregate copper and fiber links from data centres and enterprise
networks, while providing long haul fiber links.

Installation Procedure
Before you begin:
■Unpack the expansion module.
In an anti-static environment, remove the expansion module from its packing
material. Be sure to observe ESD precautions.
Caution Failure to observe proper anti-static procedures may damage the
unit. If you are unsure about correct procedures, contact your authorised
Allied Telesis distributor or reseller.
■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.
■Read the safety information for the switch.
Safety information is available in the Installation and Safety Guide that is on
the CD-ROM for the x900-24X Series switch. Or you can download this
document from www.alliedtelesis.com/support/software.
■Gather necessary tools.
You may need a Phillips #2 screwdriver to adjust the retaining screws on a
blank faceplate.
Procedure
If you want to swap expansion modules, first save your configuration file as
necessary (with create config and set config commands).
1. If connected, disconnect the switch from its redundant power supply.
2. Disconnect the switch from its AC or DC power supply.
3. Loosen the thumbscrews to the faceplate or existing expansion module,
and remove it.
Keep the faceplate for future use. If you remove the expansion module,
cover the bay with the faceplate to prevent dust and debris from entering it
and to maintain proper airflow.
4. Carefully slide the module into the empty bay until you feel it engage the
rear plug.

5. Secure the module by tightening the thumbscrews on it.
6. Apply power to the switch by re-attaching the power cord.
7. If you disconnected a redundant power supply, reconnect it.
8. Restart the switch and verify installation with the show log command to
confirm there is no error message about installation in the log file.
If you are connected to the asyn0 port, any error message is displayed
during startup self-tests.
