The manual covers installation procedures for both factory-configured expanders and add-on units, and is intended for Digital Customer Services personnel and qualified self-maintenance customers.

Key topics include:

• System Overview: Descriptions of the B400X expander, its mass storage area, power supply, fan tray, and connector panels.
• Installation Procedures: Detailed step-by-step instructions for preparing the system for expansion, unpacking, positioning the expander, modifying it, installing modules and storage devices, and connecting all necessary cables (Q-bus, DSSI, SCSI, power, and ground).
• System Configuration and Verification: Guidance on configuring modules, checking system configuration worksheets, and verifying system operation after installation.
• Appendixes: In-depth information on configuring the KFQSA storage adapter, programming parameters for RF-Series ISEs, related documentation, maintenance notes, and a list of field replaceable units (FRUs).

The document also includes important warnings, cautions, and notes related to safety and equipment handling throughout the installation process.
