Cleaning, And Working With, Internal Devices - NEC Storage ST1220 User Manual

User Guide
Do not use the equipment in the place where corrosive gases exist.
Make sure not to locate or use the server in the place where corrosive gases
(sulphur dioxide, hydrogen sulphide, nitrogen dioxide, chlorine, ammonia,
ozone, etc) exist.
Also, do not set it in the environment where the air (or dust) includes
components accelerating corrosion (ex. sulphur, sodium chloride) or conductive
metals. There is a risk of a fire due to corrosion and/or short-circuits of an
internal printed board.
Do not lift the unit by its handle or front bezel.
The handle or the front bezel may be disengaged, causing personal injury or
damages to the Disk Expansion Unit and surrounding devices. Carry the unit
with somebody else, holding firmly the bottom of the Disk Expansion Unit.

Cleaning, and Working with, Internal Devices

Do not disassemble, repair, or alter the Disk Expansion Unit.
Do not attempt to disassemble, repair, or alter the Disk Expansion Unit on any
occasion other than those described in this User's Guide. Failure to follow this
instruction may cause an electric shock or fire as well as malfunctions of the
chassis.
Disconnect the power plug before cleaning the Disk Expansion Unit.
Make sure to power off the Disk Expansion Unit and disconnect the power plug
from the power outlet before cleaning or installing/removing option boards.
Touching any internal device of the Disk Expansion Unit when its power cord is
connected to a power source may cause an electric shock or a fire due to short
circuits, even if the Disk Expansion Unit is powered off.
Occasionally disconnect the power plug from the outlet and clean the plug with
a dry cloth. Heat may be generated if condensation forms on a dusty plug,
causing a fire.
High temperature
Immediately after the Disk Expansion Unit is powered off, its internal
components such as hard disk drives are very hot. Let the installed components
fully cool down before installing/removing anything.
Make sure to complete cable and board installations.
Always install the power cable, interface cable, and option boards firmly. An
incomplete installation may cause a contact failure, resulting in smoke or fire.
