HSR95 Cabinet and Rackmount HSC95 Controller Install Manual

This manual, "HSR95 Cabinet and Rackmount HSC95 Controller Installation Manual," provides comprehensive procedures for the installation, upgrade, and maintenance of the HSR95 cabinet and rackmount HSC95 controllers. It is specifically intended for Digital Multivendor Services engineers and other qualified personnel.

Key areas covered in the document include:

• System Overview: An introduction to the HSR95 cabinet, which can house one or two rackmount HSC95 controllers and up to eight StorageWorks building block (SBB) shelves. It describes the HSC95 controller as a high-speed server for data management between disk/tape drives and a host system, connecting via CI, SDI/STI/SCSI, and EIA cables. It also highlights the unique mechanical details and operator controls of the rackmount HSC95 configuration compared to standard models.
• Installation Procedures: Detailed steps for site preparation (environmental, power, floor space requirements), unpacking, leveling the HSR95 cabinet, and physically installing components such as add-on HSC95 controllers and SBB shelves. This includes instructions for mounting slides, brackets, and cable management trays.
• Cabling and Connections: Comprehensive guidance on connecting various cables, including CI, console, SDI/STI, and SCSI cables. It provides specific routing guidelines, tie-wrap instructions, and details on connecting power cables to the system's power controllers.
• Switch Settings and Configuration: Critical procedures for checking and setting switch positions on K.pli2, K.si, and especially the LINK Module (L0118–YA). This section emphasizes the importance of correctly setting node address switches and slot count timing switches to prevent VAXcluster disturbances.
• Power Application and Initial Checkout: Instructions for safely applying power to the rackmount HSC95 controller and performing an initial UART Echo Test to ensure proper communication.
• System Parameter Configuration: Procedures for setting key system parameters such as the System Identification Number, HSC Controller System Name, and Storage Allocation Class using utilities like SETSHO and KSUTIL, and configuring the HSC SCSI Data Channels for single-path and dual-path setups.
• Device Integrity Tests: A significant portion of the manual is dedicated to explaining seven different device integrity tests (ILRX33, ILMEMY, ILCACH, ILDISK, ILTAPE, ILTCOM, ILEXER). For each test, it outlines system requirements, operating instructions, test termination, parameter entry, progress reports, test summaries, and detailed error messages with troubleshooting hints. These tests are crucial for verifying hardware functionality and diagnosing issues.
• K.scsi Module Replacement: A dedicated appendix describes the process of removing and replacing a K.scsi data channel module, including verifying jumper and terminator settings, and interpreting LED status and diagnostic codes.
• Safety Information: Throughout the document, explicit warnings are provided regarding hazardous voltages, electrostatic discharge (ESD) precautions, and the safe handling of heavy equipment to prevent injury and damage.

The manual serves as a vital resource for ensuring the correct installation, configuration, and maintenance of Digital's HSR95 cabinet and HSC95 controllers.
