StorageWorks SW500 Series Cabinet Cable Dist. Unit Install Gde

This document, the StorageWorks SW500-Series Cabinet Cable Distribution Unit Installation Guide (EK-SW5CU-IG.B01), provides instructions for two main procedures:

1. Replacing a Cable Distribution Unit (CDU): It outlines the steps for replacing an existing CDU, covering initial checks, safely powering down affected disk and tape drives (unless a dual power option is already configured, allowing the system to remain on), disconnecting the unit's primary power cable from both the source and the CDU, physically removing the old CDU, installing the replacement, reconnecting all power, and finally, restoring system operations. Key warnings include precautions against hazardous voltage and sharp cabinet edges.

2. Installing the Cabinet Dual Power Option: This section details how to add a second CDU (CDU B) to enable dual power capability. The process involves familiarizing with CDU locations, powering down drives (and potentially isolating the host system by disconnecting interface cables), preparing the cabinet, physically mounting CDU B, and connecting its internal power cords. It crucially emphasizes the proper application of 'A' and 'B' labels to differentiate primary power cables and 'CAUTION' labels for safety, ensuring the installation of redundant DC power supplies, connecting all power cables (CDU A to its source, CDU B to an auxiliary source), and finally, powering on both CDUs and verifying system function.

The document also includes general information, disclaimers, and compliance statements regarding FCC, UL, CSA, and TÜV standards.
