Installation guide

First unpack the TU tape drive cabinet. Then position the TU cabinet next
to the system cabinet (the tape cabinet can be positioned on either side of
the system cabinet, depending on the customer’s configuration). Install the
signal cables and power cable.
At the rear of the system cabinet:
1. Open the door.
2. Insert the tape unit signal cable into the designated I/O panel and
secure it with two screws.
3. Plug the tape unit power cord into the appropriate receptacle.
4. Refer to the TU81/TA81 and TU/81 PLUS Subsystem User’s Guide for
operating instructions.
The KLESI-B adapter runs a self-test during power-up. A yellow LED on
the module lights to indicate that the module passed self-test. The system
self-test display reports the status of all controllers (see Section 7.2 and
Section 7.3). For troubleshooting information, refer to the KLESI-B Module
User and Installation Guide.
