the cover is off, turn power off and unplug the
power cable from the outlet. Do not attempt
to remove the object while the power is on.
Do not put the router on an unstable or
uneven place. Put it on a stable and flat surface to prevent it from falling and
causing damage.
When installing the GR2000-B on a desk, lay it down horizontally on it’s rubber
feet. If you stand it vertically or lean it against a wall, it could fall down and cause
damage to itself or a person.
Make sure that the router is in a stable, secure position when mounting it into a
rack. If you try to install it without anchoring it to the rack, it could fall out of the
rack.
Do not put a metal object, such as a pin
or paperclip, or a vase or flower pot on the
GR2000-B. Water or object getting into
the chassis could cause a severe electrical
shock to anyone touching the router.
Do not use a power source or voltage that
exceeds the specifications of the
GR2000-B. Observe markings on the chassis.
To prevent electric shock, use only grounded power outlets.
Do not use adapters to connect multiple power cables to the same outlet. Doing
this can cause a fire and can cause a circuit breaker to trip due to an overloaded
circuit.
Do not put a heavy object on a power cable, since it could crush it. Similarly,
don’t pull, bend or otherwise mutilate the power cable, since this could cause a
fire or electric shock.
Use the power cable packed along with a chassis. If you use a power cable other
than this, it could cause a fire or an electric shock. In addition, do not use this
power cable for devices other than the GR2000-B. If you do, it could cause a fire
or electric shock.
Do not put a power cable under the device. Doing this might cause a fire or an
electric shock.
If the power cable is ever damaged so that the wires underneath the covering are
visible or cut, stop using it and ask a maintenance staff to replace it. If you
continue to use a damaged cable, it could easily cause a fire or electric shock.
Remove the cable lock metal, and
unplug the cable.

GR2K-GA-0007 xv
Rev. 5.00
Make sure that the power plug is clean when you insert it into the device or into
the AC source. A fire or an electric shock can be caused by dust or incomplete
connection.
Do not insert any foreign objects into
the device or the ventilation slots.
Doing so may cause fire or electric
shock.
Before removing the cover from the
GR2000-B, turn off the power switch
and unplug all the cables including the
power cable. Even if the power switch
is turned off, electricity continues to be conveyed into the electric circuit through
the cables connected to the device, which can cause a fire or electric shock.
Removing the cover from the device should be done
by a trained engineer or a maintenance staff. This
label is attached to the device.
If the device is dropped and any part is broken, turn
the power switch off, unplug the power cable from
the outlet, and contact service. Continued use may
cause fire or electric shock.
Do not remodel the device. Doing this causes a fire
or an electric shock.
Turn off the power switch when installing or
replacing additional network interface boards or
memory modules.
Do not install the GR2000-B in a dusty or humid location. Doing so may cause
fire or electric shock.
Condensation may form on the surface and inside of the GR2000-B if it is moved
from a cold to a warm location. Using the device in this condition may cause fire
or 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 block the ventilation slots. If
you block the ventilation slots, the
inside of the router will overheat and
cause a fire. Secure at least 70 mm of
space on each side of the GR2000-B to
ensure proper air flow through the ventilation slots.
Do not put a heavy object weighing more than 5 kg on the GR2000-B. If you do, it
could damage the router, or else make it fall over and causing damage or injury.
Do not stick your fingers into the
ventilation slots, or allow your hair to
get near the ventilation slots. This
can cause electrical shock or other
physical injuries cased by working
parts.

Caution
Move the device carefully. Before doing so, unplug the power and other cables.
Failure to follow this warning may damage the router or cables, or could cause
fire or electric shock.
Don’t pile this equipment up on top of on another when moving it. Try to store
each device in it’s own box when transporting it to prevent it from being deformed
or damaged.
Do not put the power cable near a heating apparatus. Doing so melts the coating
of the cable and can cause a fire or electric shock.
Always hold the power plug when
inserting or removing the power cable
into or from and outlet Pulling on the
cable can causes the wires to break.
This router contains a lithium battery
for the real-time clock. Mishandling this
battery may cause heat build-up,
damage, or in an extreme case,
explosion or fire. Do not remove the
battery from the router, attempt to
disassemble it, or expose it to
temperatures of over 100°C (212°F).
Do not step on the router or place heavy
objects on it weighing more than 5 kg
on the device. Doing so can damage it.
While the access indicator (ACCESS) for
a memory card is lit, the memory card is
being accessed. DO NOT pull out a
memory card or turn off the power
switch while the memory card is being
accessed. If so, you could permanently
damage the memory card. Some
commands require a long time to finish
accessing a memory card when they are
executed. Make sure that the access to a memory card is finished before pulling it
out or turning off the power switch.
Be careful with the laser outputs on optical network
interfaces. The board with the label below shows that a laser
is used in it. As the amount of its emission is small, there is
no risk of damaging your skin. Still, never look into the
output directly. There is nothing to see inside.
Wear a wrist strap to prevent static electricity. Without a wrist strap, the device
might be damaged due to static electricity.
Do not over tighten the attachment screws when connecting a cable to the router.
Over tightening the screws could cause them to break. Use only a small,
flat-blade screwdriver to tighten the screws so as not to exert excessive torque on
the screws.
Be careful how you handle the NIFs. Since they are static sensitive, handle NIFs
only by the board edges. When you store NIFs, place them in anti-static
packaging and protect them from physical damage.

Make sure that you have either a NIF in, or dummy panel installed over, an
option slot. If not, air may not circulate correctly inside the router.
For the installation of a network interface board, use a screw driver when
fastening screws and make sure that the screws are fixed firmly, but do not
overtighten.
Take care so that the fan cables, etc. are not snagged or crushed inside the router
when replacing the cover.
Clean the device only with a clean, dry cloth or use a cloth that has been
dampened (not wet) with water or another pH-neutral liquid. Do not use volatile
organic solutions such as benzene or paint thinner, chemicals, chemically
treated cloths or pesticides, which may deform, discolor or damage the router.
Do not place the router in direct sunlight or
near heat sources that may cause damage.
If the router is placed together with a radio
or a TV, they might affect each other in an
unfavorable way. If you hear the burst of
noise on a TV or a radio, do the following:
Place the device as far away from a TV or a
radio as possible.
Turn the antenna of a TV or a radio to
another direction.
Do not use the same outlet as the router.
Unplug the power cable from the outlet when the router is not used for long
periods.
Dispose of exhausted devices or boards, including lithium batteries, as required
by local regulations.
