This section contains the procedure for replacing an XEM2 Ethernet line
card in the x950 Switch. The illustrations in the procedure show the XEM2-
12XT line card. The procedure is the same for all cards. Please review the
following guidelines before performing the procedure:
All XEM2 line cards are hot-swappable. You do not have to power

off or reboot the switch when installing or replacing a line card.
When powered on, an XEM2 line card might require up to thirty

seconds to initialize its management software and begin
forwarding network traffic.
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
Switches.
Note
The XEM2 Line Cards are also used in the SBx908 GEN2 Switch.
Please note that you have to reboot that switch when hotswapping
the XEM2-1CQ Line Card.
This procedure requires a #2 Phillips-head screwdriver (not provided).
To remove an XEM2 line card from the switch, perform the following
procedure:
1. Label and remove all cables from the line card.
2. If the line card has fiber optic transceivers, install dust covers on the
ports.
3. If the line card has transceivers or direct attach cables, label and
remove the transceivers or cables.
Warning
The temperature of an operational transceiver may exceed 70° C
(158° F). Exercise caution when removing or handling transceivers
with unprotected hands.  E43
