SwitchBlade x8112 Chassis Switch and AT-SBx81CFC960 Card Installation Guide
If the problem is with the AT-SBx81XS16 or AT-SBx81XLEM Line Card,
check the following items:

Verify that the version of the AlliedWare Plus Operating System on
the AT-SBx81CFC960 Controller Fabric Card supports the card.
The AT-SBx81XS16 Line Card requires version 5.4.4 or later. The
AT-SBx81XLEM Line Card requires version 5.4.6 or later. To
determine the version number of the operating system on the
controller card, start a management session on the chassis and
issue the SHOW SYSTEM command in the Privileged Exec mode.
For instructions, refer to "Displaying the Management Software
Version Number" on page 307. If necessary, update the operating
system on the controller card. For instructions, refer to the
Software Reference for SwitchBlade x8100 Series Switches
 Verify that the line card is installed in a supported slot in the AT-
SBx8112 Chassis. The AT-SBx81XS16 and AT-SBx81XLEM Line
Cards are support in slots 1 to 4, 8, and 10. The cards are not
supported in slots 7, 9, 11, and 12. The controller card generates
an error message if a card is installed in an unsupported slot.
 Verify that the controller card in the chassis is the AT-
SBx81CFC960 Controller Fabric Card. The AT-SBx81XS16 and
AT-SBx81XLEM Line Cards are not compatible with the AT-
SBx81CFC400 Controller Fabric Card.
