Cautions
Move the device carefully. Before doing so, unplug the power and other cables.
Failure to follow this warning may damage the device or cables, or could cause a fire
or electric shock.
Do not step on the device, place heavy objects on it, or lean against it. Doing so
could cause the device to be damaged directly, or indirectly from a fall.
The weight of each optional component for GR4000 or GS4000 is listed in the table
below. Be careful not to injure yourself when handling these components.

When detaching the AC power supply unit from GR4000-320E (AC) and GS4000-
320E (AC), or the DC power supply unit from GR4000-160E2, GS4000-160E2,
GR4000-320E (DC) and GS4000-320E (DC), do it by holding its handle firmly, so
that it cannot drop accidentally and cause injury. Comply with the instructions
written on the caution label attached on the device.
Do not install the device in a dusty or humid location. Doing so may cause a fire or
an electric shock.
Condensation may form on the surface and inside of the device if it is moved from a
cold to a warm location. Using the device in this condition may cause a fire or an
electric shock. After moving the device between two locations with a large
temperature variation, let the device stand for a few hours before using.
Do not put your hands into the device when it is operating, since you could be
injured by a moving part.
Do not put the power cable near a heater, since it could melt the power cable casing
a fire or an electric shock.
Always hold the power plug when inserting or removing the power cable into or from
the outlet. Pulling on the cable can causes the wires to break.
Be careful with optical network interfaces. The board with the label (shown below)
shows that a laser is used. Never directly look into the optical ports.
