If a foreign object falls into the device when the cover is off, turn power off and
unplug the power cable from the outlet. Using the device with power on could cause
a fire or electric shock. Do not attempt to remove the object while the power is on.
Do not put the device on an unstable or uneven place. Instead, put the device on a
stable and flat surface to prevent it from falling and causing damage.
When installing the GR4000 or GS4000 on a desk, lay it down horizontally in it’s
normal orientation. If you stand it vertically or lean it against a wall, it could fall and
be damaged and potentially cause injury.
Do not remove the cover when it is operating, since this can cause you to receive a
shock.
Make sure that the device 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.
In the event that the device or any of it’s components is damaged, immediately turn

Do not use a power source or voltage that exceeds the specifications of the GR4000
or GS4000. Observe the instructions on the device chassis.
The current capacity of a distribution panel must be greater than that of the
operating current fed to the circuit breaker. If not, the circuit breaker may not work
properly when a circuit abnormality is detected. This condition could cause a fire.
Because DC power cables are connected using screw terminals instead of plugs,
attaching or removing a DC power cable to or from the device must be done by a
trained maintenance person. Mishandling DC power cables can cause a fire or an
electric shock.
Make sure that the circuit breaker of a power facility is set to OFF before attaching
or removing a DC power cable. Attaching or removing a DC power cable with the
circuit breaker set to ON will cause an electric shock.
When replacing a power supply unit or installing an additional one, remove the
power cable from the power supply unit to be replaced. Even if the power switch is
turned OFF, electricity is still present in the cables connected to the device, which
can cause a fire or electric shock.
When using a DC power cable, attach an insulating sheath at the cable terminal.
Using a unsheathed DC power cable could causes an electric shock.
After attaching a power cable, attach the cover to the terminal plate when using DC
power supply unit. Otherwise one of the power supply unit terminals could short
out or you could receive a shock.
Installing or replacing an optional unit, such as a network interface (NIF) must be
done by a trained maintenance person.
When connecting the device to the DC power supply unit, use the EARTH
(GROUND) terminal to avoid an electric shock or the trouble related to electric
noises.
To measure the voltage at a DC-powered device, the end terminal is attached to the
DC power unit. To avoid a fire or an electric shock, do not insert small pins or paper
clips into the terminal.

GR4000 Installation Guide Version 1.00 - Preliminary
520-10-014-20X xiii
Do not allow a heavy object to be placed 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 an electric shock.
There will be a maximum of 3.5 mA of leakage current with the GR4000-80E1,
GS4000-80E1, GR4000-160E1, and GS4000-160E1 and a maximum of 6 mA
leakage current with the GR4000-320E (AC) and GS4000-320E (AC). When
connecting the device to the AC power supply unit, use only grounded power
outlets. Failing to use grounded outlets creates a shock hazard. Furthermore, you
could introduce unwanted electrical noise into the device, which could degrade
performance.
Since a substantial amound of leakage current flows in the GR4000-320E (AC), be
careful when handling it and comply with the instuctions in the label below:
Use the power cable packed with the device. Similarly, do not use the device’s power
cable for the equipment other than the GR4000 or GS4000. In both cases, using an
improper cable could 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 person to replace it. Using
damaged cables could easily cause a fire or an electric shock.
Do not use adapters to connect multiple power cables to the same outlet. Doing this
can cause a fire or cause a circuit breaker to trip due to an overloaded circuit.
This device may have multiple power supplies installed, each having a separate
source of mains power. When turning power OFF to the device, make sure that all
the power switches and circuit breakers attached to the device are set to OFF.
Comply with the instructions written on the label attached to the device:
Do not block the ventilation slots. If you block the ventilation slots, the inside of the
device will overheat and could cause a fire. Reserve at least 70 mm of space from
the ventilation slots of each device to ensure proper air flow through the ventilation
slots.
As shown in the drawings below, the ventilation slots are on the front, back, right,
and left sides for the GR4000-80E1, GR4000-160E1, GS4000-80E1 and GS4000-
160E1, and they are on the right and left sides of the GR4000-80E2, GR4000-
160E2, GR4000-320E (AC), GR4000-320E (DC), GS4000-80E2, GS4000-160E2,
GS4000-320E (AC), and GS4000-320E (DC).

GR4000 Installation Guide Version 1.00 - Preliminary
xiv 520-10-014-20X
Cooling fans are mounted in the device. Therefore, do not put an object near the
ventilation slots. Doing this causes heat inside the device to accumulate and might
damage it. Also, do not put your head near the ventilation slots, since your hair
could be sicked into the into the device, causing injury.
Wait at least two seconds before restarting a GR4000 or GS4000 once it has been
powered off.
While the access lamp (ACC LED) for a basic control unit (BCU) is lit, the memory
card (MC) 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.
When moving the device, do not hold the handle of a power supply unit. These
handles are not intended for this purpose and could break off, causing the power
supply unit and the device to fall, which could cause injury to you. The device itself
could also be damaged, which could cause a shock or fire hazard.
Do not install optional components from a GR4000 or GS4000 into devices other
than another GR4000 or GS4000. Doing this could cause a fire or an electric shock.

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.

CLASS1 LASER PRODUCT
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.

When installing a packet routing (switching) unit into the device, open its levers as
shown in the figure below. If you try to install it with its levers closed or open too
wide, the levers could be damaged when being inserted into the slot.
Levers
When carrying or packing optional units, such as NIFs, BCUs, PRUs, PSUs, memory
modules, memory cards, and power supplies, do not touch the electronic
components or circuitry on the solder side. To avoid damage, always store these
boards and components in approved anti-static bags.

Do not put objects on a packet routing (switching) unit. Doing this might deform the
outer frame of a packet routing (switching) unit Comply with the instructions
written on the label put on a packet routing (switching) unit . (See below.)
No Pile Up
Not For Handling
Caution
Do not hold the area marked with in the figure below when mounting or
removing a Packet Routing Unit (PRU) from a GR4000 model, or a Packet Switching
Unit (PSU) from a GS4000 model. Doing so might deform the outer frame of the PRU
or PSU, and the NIF might be damaged if you try to insert it into a PRU or PSU with
its deformed outer frame.
Do not place the device in direct sunlight or near other heat sources that may cause
damage.
If the device is placed near a radio or 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.
Adjust the antenna of a TV or a radio to another direction.
Use a different AC outlet for the TV or radio from that used for the GR4000
or GS4000.

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, since these substances may deform, discolor or damage the device.
Unplug the power cable from the outlet when the device is not used for long periods.
If you are using the DC power supply unit, switch off the circuit breaker at the
power facility.
Always dispose of exhausted devices or boards in an environmentally responsible
manner and as required by your local regulations. The GR4000 or GS4000 contains
lithium batteries, circuit boards containing copper, lead and tin, cables and
connectors, all of which can be recycled.
Do not install optional components or accessories for the GR4000 or GS4000 on
devices other than the GR4000 or GS4000. Doing so could cause a fire or an electric
shock.
The GR4000-80E2, GR4000-160E2, GS4000-80E2, and GS4000-160E2 must be
installed in a restricted-access location. This location should ensure that access to
the device can be gained only by service personnel through the use of a special tool,
lock and key, or other means of security, and is controlled by the authority
responsible for the location.
