Upgrade and Maintenance Guide
Preface
Electrostatic Discharge Guidelines
Document Conventions
This manual uses the following standard set of typographical conventions to introduce new terms, illustrate
screen displays, describe command syntax, and so forth.
Electrostatic Discharge Guidelines
Follow these ESD guidelines to ensure that your equipment is not damaged from improper handling:
When you install or perform maintenance tasks, you must wear a grounded ESD antistatic strap to
protect the hardware against electrostatic discharge. Make sure that the strap makes skin contact prior
to handling equipment.
Periodically check the resistance value of the antistatic strap to ensure it is functioning properly.
If you remove or replace system components, you must transport the component in a conductive
container or an ESD bag that has been grounded or neutralized.
Store any system components in their protective packaging until you are ready to install them.
Do not touch the electronic components on system hardware.
Safety Guidelines
Follow the safety precautions outlined in the
Safety and Compliance Guide
when installing and setting up
your equipment.
Caution:
Failure to follow these safety guidelines can result in injury or damage to the equipment. Mishandling of the
equipment voids all warranties. Read and follow safety guidelines and installation instructions carefully.
