Preventing electrostatic discharge
Electrostatic discharge (ESD) can cause component damage, especially during servicing operations.
Static charges occur when objects are separated or rubbed together. The voltage level of a static
charge is determined by the following factors:
•
Types of materials
•
Relative humidity — low humidity increases ESD voltage
•
Rate of change — a standard air conditioner cools the air and lowers humidity. The faster the air
is cooled and dried, the greater the likelihood of ESD.
•
Separation — refers to the static discharge that can be generated when two objects are separated.
For example, printer paper is often stored in cool dry conditions. If opened and used immediately,
the act of removing the paper from its box generates static. To allow the static to discharge
gradually over time, leave the box open in the computer room for several hours before use.
Follow these precautions to minimize possible ESD-induced failures in your computer room:
•
Install conductive flooring (conductive adhesive must be used when laying tiles).
•
Use conductive wax if waxed floors are installed.
•
Ensure that all equipment and flooring are properly grounded and are at the same ground potential.
•
Install ESD grounding kick plates provided (XP24000 DKC and each DKU).
•
Use conductive tables and chairs.
•
Store spare electric parts in antistatic containers.
•
Use the ESD strap provided with the DKC.
NOTE:
Straps not shipped with DKU for XP240000 or XP20000.
•
Maintain recommended humidity level and airflow rates.
Safety requirements
When making decisions concerning site safety, your first concern should be the safety of your personnel
and then the safety of your equipment.
Fundamental safeguards for disk arrays should include a site well away from any sources of potential
damage.
If you have any questions on site safety, consult your HP representative, your insurance carrier, and
local building inspectors for safety recommendations.
Fire safety requirements
WARNING!
Do not install or operate the disk array in an environment where there is a risk of fire or explosion
due to the presence of highly flammable gases, volatile liquids, or combustible dust.
