WARNING
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 any components on the CPU blade with it connected to 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.
CAUTION
Keep water or foreign matter away from the server.
Do not let any liquid such as water or foreign materials including pins or paper clips enter the server.
Failure to follow this warning may cause an electric shock, a fire, or 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, and contact the store where you purchased the product or your
maintenance service company.
Make sure to complete device installation.
Always install an interface cable, CPU blade, Solid State Drive, and option board firmly. An incompletely
installed device may cause a contact failure, resulting in smoking or fire.
Use only the specified interface cable.
Use only interface cables authorized by NEC and locate a proper device and connector before connecting
a cable. Using an unauthorized 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 server with loose cable connections.
• Do not use any damaged cable.
High temperature
Components including internal Solid State Drives in the server are extremely hot just after the server is
turned off. Allow the surface to cool before installing/removing.
Avoid contact with the server during thunderstorms.
Do not touch any part of the server including the cables when a thunderstorm is approaching. Also, do not
connect or disconnect any devices. There may be a risk of electric shock from lightning strike.
Keep animals away from the server.
Keep animals such as pets away from the server. Pet hair or other waste enters the server, which may
cause a fire or electric shock.
