Overview

This guide demonstrates how to replace a bus bar clip in an Open Vault system. == Acronyms and Terms == * HDD - Hard Disk Drive * Mini-SAS - Mini Serial Attached SCSI * SCSI - Small Computer System Interface === Additional Notes === It is not absolutely necessary to remove trays from the Open Vault chassis to replace the Powerblade cable. This section of the replacement guide may be treated as a preference.

The types of cables, allowed in cable tray, and the wiring methods permitted in cable trays can be found in NEC Section 392.10 (A). This Section also lists various corresponding NEC Articles which describe the conditions of use and installation requirements for a particular class or type of cable. Additional considerations such as fill capacity, allowable ampacity, cable splicing within trays, and securing and supporting cables are addressed in Article 392. Users should be familiar with all these Articles and check the manufacturer’s specifications, to verify selected cables meet all application requirements and NEC requirements.
