Replacing AT-XEM2 Line Cards
This section contains the procedure for replacing AT-XEM2 Ethernet line
cards in the AT-SBx908 Gen2 Switch. The illustrations in the procedure
show the AT-XEM2-12XT line card. The procedure is the same for all
cards. Please review the following guidelines before performing the
procedure:
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
SwitchBlade x908 Gen2 Switches
.
All AT-XEM2 Line Cards are hot-swappable. You do not have to
power off the switch to install or replace them.
Ethernet line cards require up to thirty seconds before they
become fully operational.
All line cards, with the exception of the AT-XEM2-1CQ Card, can
be replaced with cards of the same model without having to reboot
the switch. For example, no reboot is required when replacing an
AT-XEM2-12XS Line Card with another AT-XEM2-12XS Line
Card.
All line cards, with the exception of the AT-XEM2-1CQ Card, can
be hotswapped with different card models without rebooting the
switch. For example, no reboot is required when replacing an AT-
XEM2-12XS Line Card with an AT-XEM2-4QS Line Card.
Rebooting the switch is required when you hotswap an AT-XEM2-
1CQ Line Card.
This procedure requires a #2 Phillips-head screwdriver (not provided).
To remove an AT-XEM2 Line Card from the switch, perform the following
procedure:
1. Label and remove the 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 connect cables, label and
remove them.
Warning
The temperature of an operational transceiver may exceed 70° C
(158° F). Exercise caution when removing or handling transceivers
with unprotected hands.
