Cleaning And Handling Of Internal Devices - NEC Bull NovaScale R620 Series Setup Manual

Cleaning and Handling of Internal Devices

Do not disassemble, repair, or alter the server.
Unless described herein, never attempt to disassemble, repair, or alter the server. There is a risk of
an electric shock or fire as well as malfunction.
Do not look into the CD-ROM drive.
The CD-ROM drive uses a laser beam. Do not look or insert a mirror inside while the system is on. A
laser beam is invisible; if your eyes get exposed to it, there is a risk of losing eyesight.
Do not detach a lithium battery yourself.
This equipment has a lithium battery. Do not detach it yourself. If the battery is exposed to fire or
water, it could explode.
When the lithium battery is running down and the server does not work correctly, contact your sales
agent instead of disassembling, replacing or recharging it yourself.
Disconnect the power plugs before cleaning the server.
Even though built-in options for the server can be replaced while the power cords are connected to
power source, be sure to follow the instructions described in this User's Guide. Do not touch any
internal device of the server unless instructed by this User's Guide. There is a risk of an electric
shock.
Make sure to power off the server and disconnect the power plug from a power outlet before
cleaning or installing/removing internal optional devices. Touching any internal device of the server
with its power cords connected to power source may cause an electric shock even if the server is
off-powered.
Disconnect the power plug from the outlet occasionally and clean the plug with a dry cloth. Heat will
be generated if condensation is formed on a dusty plug, which may cause a fire.
High temperature
Immediately after powering off the system, system components such as hard disk may be very hot.
Wait for the server to cool down completely before adding/removing components.
Make sure to completely insert cables and boards.
Completely insert all power cords, interface cables and/or boards. An incompletely inserted
component may cause a contact failure, resulting in fire and/or smoke.
Protect the unused connectors with the protective cap.
The unused power cord connectors are covered with a protective cap to prevent short circuits and
electrical hazards. When removing the power cord connector from the internal devices, attach the
protective cap to the connector. Failure to follow this warning may cause a fire or an electric shock.
