About this guide

This guide provides information about:

•Maintaining the MSA

•Servicing the MSA

WARNING!

To reduce the risk of personal injury from electric shock and hazardous energy levels, do not exceed the

level of repairs speciﬁed in these procedures. Troubleshooting and repair procedures included in this

document are detailed to allow only subassembly/module-level repair. Because of the complexity of the

individual boards and subassemblies, do not attempt to make repairs at the component level or to make

modiﬁcations to any printed wiring board. Improper repairs can create conditions that are hazardous.

NOTE:

Any indications of component replacement or printed wiring board modiﬁcations may void any warranty.

Intended audience

This guide is intended for use by system administrators and technicians who are experienced with the

following:

•SAN management

•Network administration

•Network installation

Prerequisites

Before servicing the MSA, make sure that you consider the following:

•Knowledge of operating system

•Knowledge of related hardware/software

•Previous version of the product and/or ﬁrmware version
