StorageWorks SH043-Series Cab Cable Dist Unit Inst Guide

This document, the "StorageWorks SH043-Series Cabinet Cable Distribution Unit Installation Guide," provides step-by-step instructions for two main procedures:

1. Replacing a Cable Distribution Unit (CDU): This section details how to swap out an existing CDU in an SH043-series cabinet. It covers preparing the system (e.g., spinning down drives), disconnecting the old CDU from power sources and internal connections, physically removing and installing the new unit, and then reconnecting power and restarting the system. It notes that the primary power cable can often be reused.
2. Installing the Cabinet Dual Power Option: This procedure explains how to add a second CDU (CDU B) to enable a redundant power configuration. Key steps include preparing the existing CDU (CDU A), installing and connecting CDU B with its internal power cords, meticulously applying specific safety labels to both primary power cables and the cabinet, ensuring redundant DC power supplies are present, and connecting both CDUs to separate power sources before system restart.

The guide emphasizes safety throughout, with warnings about hazardous voltage and sharp cabinet edges, particularly stressing the critical importance of correct labeling for dual power configurations to prevent electrical shock and operational confusion.
