TS3400 Tape Library Maintenance Information
Replacing the Accessor Flat Cable Plate Assembly
The Accessor flat cable forms the communication and control path between the
Library Control Blade and the Accessor. The cable loops back upon itself lengthwise,
on a plate assembly along the length of the library, as the accessor moves backward
and forward accessing cartridge slots and loading/unloading the tape drives.

2. In the Operator Panel top menu, select Unlock Magazine , and press Enter.
