StorageWorks SCSI Controller Shelf Upgrade/Add-On Kits Installation Guide

This document, "DIGITAL StorageWorks SCSI Controller Shelf Upgrade/Add-On Kits Installation Guide," provides detailed procedures for installing the DS-BA356-MD Series array controller shelves.

The guide primarily addresses two scenarios:

1. Shelf Upgrade: Replacing an older BA350-M series shelf with a new DS-BA356-MD shelf. This involves steps for removing the old shelf (disconnecting power, cables, modules, and mounting brackets) and then installing the replacement shelf in the same orientation.
2. Shelf Add-On: Installing a new DS-BA356-MD controller shelf as an additional unit. This includes procedures for selecting and installing the correct mounting brackets (screw-mounted or tab-mounted) based on cabinet type, inserting the shelf, and installing its internal components.

Key aspects covered in the guide include:

• Required Tools and Equipment: A list of necessary tools like screwdrivers, pliers, and ESD (Electrostatic Discharge) safety gear.
• Inventory Lists: Components included in the upgrade/add-on kits and user-ordered parts.
• Shelf Orientation: Guidance on horizontal, front-vertical, and rear-vertical mounting configurations.
• Safety Precautions: Warnings about sharp cabinet rails, proper lifting techniques, and critical ESD measures to prevent damage to hardware and ensure personnel safety.
• Installation Steps: Detailed instructions for installing I/O cables, cache modules, and controller modules, often with figures to illustrate the process.
• Post-Installation: Directives to connect power, dress cables, and refer to separate array controller configuration guides for setup and testing.

The document emphasizes adherence to a specific "Check List" for upgrades to prevent data loss and damage. It is intended for customers and employees responsible for these installation and configuration tasks.
