Allied Telesis XEMs offer a high degree of flexibility that future-proofs your network

investment against changes in network infrastructure, topologies, and physical link requirements.



XEM expansion modules can be used in a variety of configurations to provide tailored

solutions that meet wide-ranging physical networking requirements. Whatever your network

needs, Allied Telesis has a XEM that is right for the job.



Achieve expandability with the XEM-12T, which has 12 copper ports to easily add

maximum Gigabit Ethernet port density to your network.



Enjoy flexibility with the XEM-12S, with 12 SFP ports to let you aggregate both copper

and fiber links.



Network scalability is simple with the XEM-STK. Use this high speed stacking XEM to

create a single "virtual chassis" from multiple x900 switches, increasing resiliency and port

density without increasing management complexity.



Achieve high performance with the XEM-1XP and XEM-2XP 10 Gigabit Ethernet XFP

XEMs. With true ten Gigabits per second throughput, these XEMs support hot-swappable

XFPs and provide high-speed, high-capacity fiber uplinks, up to 20Gbps of non-blocking

throughput per XEM.
