Fibre Channel Connection Problems
The ACL will not operate with a full-height tape drive installed in the middle two half-
height drive bays. Verify that the full-height tape drive is in either the upper or lower two
half-height drive bays.
Use the Status screen to check the link connection for your tape drive. If the screen
shows Logged Out:
!
Check that the Fibre speed is set to Automatic (on the RMI) or Auto Detect (on the
OCP), or that the correct fibre speed is selected. If you are unsure of the speed of
the HBA or switch that the ACL is connected to, try Automatic (on the RMI) or Auto
Detect (on the OCP).
!
Check that the correct port type, fabric or loop, is selected. Loop requires
additional configuration. If you are unsure of the correct port type, try Automatic (on
the RMI) or Auto Detect (on the OCP). If the screen shows No Link, the Speed
Status is – and the Link LED on the back of the drive is off:
!
The speed is probably set incorrectly. Try setting the speed to Automatic (on the
RMI interface) or Auto Detect (on the OCP).

If there are still issues, change the port type to Auto Detect. If the screen shows No
Light:
!
The cable is not plugged in correctly. Check that it is connected correctly to Port A
of the tape drive.

Caution. This ACL is designed to operate when installed in a rack using the rack rail kit.
Operating the ACL without installing it in the rails, such as on a table or rack shelf, could result
in device errors. Placing any weight on top of the device might also cause errors.
Caution. Shipping Lock: The shipping lock must be removed for the robotics to work
