Overview
The EM-412 is an uplink module with two slots for 10GBase-
CX4. It works up to a distance of 15 meters (49 feet) with the
advantage of having the lowest cost per port of all 10Gb
interconnects. It is designed for use with high-speed
switches, such as the XGS-4528F, XGS-4728F and the 10-
Gigabit Module (MI-7308) of MS-7206. After installing the EM-
412 in a switch, the switch can have 10 Gigabit connections
to a backbone switch or other network devices.
This guide helps you set up and use your EM-412.
