which makes it impossible to be mounted on the rack. It also may cause the server to fall, resulting in
personal injury.
Do not attempt to connect or disconnect the interface cable while the power cord is plugged into
an outlet
Be sure to unplug the power cord from a power outlet before 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 a
cable or connector may cause an electric shock or a fire resulted from a short circuit.
Use only the specified 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 server with loose cable connections.
