• Keep this document at hand after you read it, so that you can always refer it later.
• For any operation involving the device, follow the directions and procedures given by
this document.
• Observe the cautions labeled on the device or those presented by this document. If you
fail to do so, you will cause damage to yourself or the device.
BEFORE USING GR4000/GS4000 SERIES ROUTERS AND SWITCHES
We have standard symbols displayed on the GR4000 or GS4000 and in the manuals to guide you
in using the GR4000 or GS4000 correctly and safely without injuring yourself and others, or
damaging equipment assets. Below are the symbols and their meanings.
*
Note: Anote is informational in nature. Unlike cautions and danger notices, notes are
not related to the physical injury or damage to the device.
!
Caution: If you ignore a caution and mistreat the GR4000 or GS4000, you could cause
physical damage to the router or surroundings, or interrupt service to your
networks users.
WARNING: IFYOU IGNORE INSTRUCTIONS PRECEDED BYAWARNING SYMBOL, YOU
COULD CAUSE PERSONAL INJURY OR DEATH TO YOURSELFAND OTHERS.
• Do not attempt to perform any operations not specifically described in the
documentation. In the event of a problem, turn off the power, unplug the power cable,
and contact a qualified service technician.

• 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 its 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 its components is damaged, immediately turn off
power and remove the power cable from the source. Contact a qualified service
technician. Using the device in a damaged condition could cause a fire or an electric
shock.
• Do not put a metal object, such as a pin or paperclip, or a vase or flower pot on the
GR4000 or GS4000. Water or objects falling into the chassis could cause a severe
electrical shock to anyone touching the device.
• To avoid injury, the GR4000-80E1, GR4000-80E2, GS4000-80E1 or GS4000-80E2
should be carried by no less than three people. The table below shows the weight of

• Also, when handling these devices, make sure that you comply with any instructions
written on the labels attached on each device.
• 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 or installing an additional one, remove the power cable
from the power supply 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
an electric shock.

• When using a DC power cable, attach an insulating sheath at the 0v and -48V/-60V
cable terminal. Using an unsheathed DC power cable could cause an electric shock.
• After attaching a power cable, attach the cover to the terminal plate when using DC
power supply. Otherwise one of the power supply terminals could short out or you
could receive a shock.
• Installing or replacing an optional module, such as a Network Interface (NIF), the
installation must be done by a trained maintenance person.
• When connecting the device to the DC power supply, use the EARTH (GROUND)
terminal to avoid an electric shock or the trouble
related to electric noises.
• To measure the voltage at the GS4000-80E2, GS4000-
160E2, GS4000-320E (AC), and GS4000-320E (DC),
the end terminals are attached to these devices. To
avoid a fire or an electric shock, do not insert small
pins or paper clips into the terminal.
• To measure the voltage at the GS4000-80E2, GS4000-
160E2, GS4000-320E (AC) and GS4000-320E (DC),
the end terminals are attached to these devices. Measuring the voltage should be done
only by engineers or qualified maintenance personnel.
• 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 of leakage current
with the GR4000-320E (AC) and GS4000-320E (AC). When connecting the device to the
AC power supply, 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 amount of leakage current flows in the GR4000-320E (AC), be
careful when handling it and comply with the instructions in the label below:
• 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).
• 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 sucked 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. Some commands can take a while to finish access to a memory card.
Always make sure that access to a memory card is completely finished before pulling
out a memory card or turning off the power switch.

• Always hold the power plug when inserting or removing the power cable into or from the
outlet. Pulling on the cable can cause the wires to break.
• Be careful with optical network interfaces. The
board with the label (shown at the right) shows
that a laser is used. Never directly look into the
optical ports.
• 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 supply is turned OFF.
• When replacing a fan 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 modules, 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 Unit (PRU for the GR4000) or Packet Switching Unit
(PSU for the GS4000) into the chassis, open its levers as shown in the figure at the right.
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.
• Whenever you use the GR4000 or GS4000 without one or
more of its option modules attach blank panels in place of
the option modules. Otherwise, air will not flow properly
through the device, which could cause the temperature
inside to rise beyond what its safe operating limit.
• When carrying or packing optional modules, such as NIFs,
BCUs, PRUs, PSUs, memory modules (DIMM), 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.
• The option modules for the GR4000 or GS4000 should be mounted only into those
devices. Option modules marked with “UL Listed Accessory” indicate that they have won
Underwriters Laboratories approval on the condition that they are mounted into the UL-
approved devices.
• Do not put objects on a Packet Routing (Switching) Unit. Doing this
might damage the outer frame of the module. Comply with the
instructions written on the label attached to the module (see right).
Do not look directry into the

• Do not hold the area marked with in the figure
at right when mounting or removing a PRU from the
GR4000 or a PSU from the GS4000. Doing so could
damage the outer frame of the PRU or PSU, and a NIF
could be damaged if you try to insert it into a PRU or
PSU with a damaged 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:
1. Place the device as far away from a TV or a radio as possible.
2. Adjust the antenna of a TV or a radio to another direction.
3. Use a different AC outlet for a 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, 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 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.
