Unused CDU Ports
Any ports on the CDU that are not connected to an ERAU will cause the built-in-
test system in the InCell system to indicate a link error condition. This error
condition will be seen on the CDU front panel Link indicators and will also
appear as a Link error at the Alarm output.
In order to not set off the alarm, each unused CDU port must have a simplex fiber
optic jumper cable between the U/L and D/L fiber optic connectors. The jumper
must have SC/APC connectors on each end. Refer to the InCell Accessories
section of this manual for a jumper part number.
