    Service Procedures

    This document describes how to replace parts or add new parts to a system.

    Before you service the system, ensure that you have received the new part and have correctly identified its intended location in the system. Go to the Unisphere Service section for instructions on how to identify failures, order new parts and safely handle hardware components.

    When servicing the system, only add or replace one component at a time. New hardware added while simultaneously servicing other components may not be recognized by the system and can cause errors.

    Note:  Review the information in Safety precautions for handling replaceable units before handling replaceable parts.
