1-8 Precautions for Use
CAUTION
Do not connect any interface cable with the power cord of the server plugged to
a power source.
Make sure to power off the server and unplug the power cord from a power
outlet before installing/removing any optional internal device or
connecting/disconnecting any interface cable to/from the server. If the server is
off-powered but its power cord is plugged to a power source, touching an
internal device, cable, or connector may cause an electric shock or a fire
resulted from a short circuit.
Do not use any non-designated interface cable.
Use only interface cables designated by NEC; identify which component or
connector to attach beforehand. If you use a wrong cable or make a wrong
connection, there is a risk of short-circuit that could lead to a fire.
You also have to observe the following prohibitions about handling and
connecting interface cables:
„ 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 equipment with loose cable connections.
