GR4000 Installation Guide Version 1.00 - Preliminary
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.
Do not look into the optical outlet/inlet ports directly.
The GR4000 or GS4000 contains a lithium battery for the real-time clock.
Mishandling this battery may cause overheating, damage, or in an extreme case,
explosion or fire. Do not remove the battery, attempt to disassemble it, or expose it
to temperatures of over 100°C (212°F). Also, do not incinerate or dispose of this
battery in water.
Remove dust on or around the device regularly. Accumulated dust can choke off
ventilation to components, causes fans to fail, and could cause a fire or an electric
shock.
Once the device is powered up, an inrush of electrical current occurs. Do not
operate this device during a reduced voltage condition (brownout). Similarly, do not
allow the voltage of a power facility under your control to decrease. A brownout
condition also affects the other equipment besides the GR4000 or GS4000 if
connected to the same power facility.
Before attaching or detaching a power cable, make sure that the switch of the
targeted power unit is turned OFF.
When replacing a fan unit while powered on, it must be done within one minute
after being detached. If replacement takes more than one minute, the temperature
inside the device will start to rise and could affect other components.
When carrying or packing the device and its optional units, wear a wrist strap to
prevent static electricity. Without a wrist strap, the device might be damaged by
static electricity.
