Notes on Expansion

Check the precautions and working methods below when performing installation tasks for options
installed in the disk array unit.
Although users can install optional products themselves, RAID assumes no responsibility for
damage to the disk array unit or components or for effects resulting from use if they do so. It is
recommended that this work be performed by maintenance engineers of your maintenance service
agent who have detailed expert knowledge about the disk array unit.
Options and cables should be parts that RAID specifies. There is a charge for repairs associated
with malfunction, failure, or damage to the unit that occurs as a result of using parts other than
those specified.
About electrostatic countermeasures
The internal parts of the disk array unit are electronic parts that are weak against static electricity.
Be careful of component failure due to static electricity when working.
Wearing a wrist strap (arm band, antistatic glove, or other)
Wrap a wrist grounding strap around your wrist. If you do not have one, touching an uncoated
metal surface of the cabinet before touching a part discharges static electricity stored in your
body.
Also periodically touch a metal surface while working so that you discharge static electricity.
Workplace checks
- Work on a floor for which measures to prevent static electricity have been taken or on
concrete.
- If working on carpet or another location in which static electricity readily occurs, do the
work after taking measures to prevent static electricity.
Use of work stands
Place the disk array unit on an antistatic mat and do the work on that as well.
Clothing
- Do not work wearing clothing made of wool and synthetic fibers.
- Work wearing antistatic shoes.
- Remove precious metals (such as rings, bracelets, or watches) before working.
Parts handling
- Put parts to install in antistatic bags until inserting them in the disk array unit.
- Hold the edges of each part and do not touch pins or mounting parts.
- When storing or transporting parts, put them in antistatic bags.
