Overview
The EM-422 is an uplink module with two slots for XFP (10-
Gigabit Small Form Factor Pluggable) transceivers. It is
designed for use with high-speed switches, such as the XGS-
4528F. After installing the EM-422 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-422.

1 Hardware Installation
Follow these steps to install the EM-422 in a switch.
"Modules are NOT hot swappable!
1Turn off your switch and unplug all power supply cords
(including any backup power supply cords) from the
switch.
2Loosen the screws from the
cover plate and remove the
cover plate from an
expansion slot on the switch.
Do not discard the cover
plate. You can put the cover
plate back on if you remove
the new module.
"Before you continue, wear an anti-static wrist
strap or touch any grounded or metal objects to
discharge any bodily static electricity.
3Remove the EM-422 from its protective anti-static
packaging. Hold the EM-422 by its edge to avoid touching
the onboard circuit components.
