becoming fully operational after being powered on.
Note
Allied Telesis recommends saving a backup copy of the
configuration file in the switch before removing or replacing line
cards. For instructions, refer to the Software Reference for x950

To remove an XEM2 line card from the switch, perform the following
procedure:

ports.

remove the transceivers or cables.
