MSL5000 and 6000 Series Tape Libraries User Guide

Introduction
31HP StorageWorks MSL5000 and MSL6000 Series Tape Libraries User Guide
Library Controller Board
The library controller board contains a single microprocessor and associated logic
devices to control all robotics operations and manage overall library functions.
The microprocessor enables the SCSI interface between the library and the host
system.
Note: The SCSI terminator must always be connected to the library controller board for
proper operation when configured as standalone or master.
The library controller board is installed in a card cage at the rear of the library and
can be serviced with a #1 Phillips screwdriver (see Figure 6). If a replacement
controller board is needed, contact your authorized service provider. Step-by-step
procedures will be included with the replacement.
Note: For MSL Series libraries, the library controller board must be installed in the
right-hand slot of the card cage area (upper card cage area for the four-drive models).
The remaining slots on the library do not support the connections that are required for
the library controller board to operate correctly.
