Do not handle the CPU blade if it is installed in the Blade Enclosure.
To install or remove an option from the CPU blade, first turn off the power of
the CPU blade and remove the CPU blade from the Blade Enclosure. If you
touch parts on the CPU blade with it connected to the Blade Enclosure, you
may get an electric shock.
Do not install or remove more than one CPU blade at a time.
Install or remove CPU blades one by one. If you install or remove more than
one CPU blade at a time or a CPU blade with the cover of another slot
removed, you may be electrically shocked.
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
(sulfur dioxide, hydrogen sulfide, 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. sulfur, sodium chloride) or conductive
metals. There is a risk of a fire due to corrosion and shorts of an internal
printed board.
Keep water or foreign matter away from the CPU blade.
Do not let any form of liquid (water etc.) or foreign matter (e.g., pins or paper
clips) enter the server. Failure to follow this warning may cause an electric
shock, a fire, or a failure of the server. When such things accidentally enter
the server, immediately turn off the power and disconnect the power plug
from the outlet. Do not disassemble the server. Contact your service
representative.
Make sure to complete device installation.
Always install a CPU blade, hard disk drive and board firmly. An incompletely
installed device may cause a contact failure, resulting in smoking or fire.
Do not use any unauthorized interface cable.
Use only interface cables provided by NEC and locate a proper device and
connector before connecting a cable. Using an authorized cable or
connecting a cable to an improper destination may cause a short circuit,
resulting in a fire.
Also, observe the following notes on using and connecting an interface cable.
Do not use any damaged cable connector.
Do not step on the cable.
Do not place any object on the cable.
Do not use the Blade Enclosure with loose cable connections.
