appropriate. Discontinue use to avoid the risk of fire or an electric shock.
 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 an 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 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 each device:

GR4000-320E (DC)
GS4000-320E (DC) 120 (264.5)
 Also, when handling these devices, make sure that you comply with any instructions written on
the labels attached on each device.

GS4000 Quick Start Guide, Revision 3
xii QSGGS4KX10-00 5794092-2X
 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.

GS4000 Quick Start Guide, Revision 3
QSGGS4KX10-00 5794092-2X 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 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).

GS4000 Quick Start Guide, Revision 3
xiv QSGGS4KX10-00 5794092-2X
 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.

GS4000 Quick Start Guide, Revision 3
QSGGS4KX10-00 5794092-2X xv
 In the following two cases, do not turn off power to the device until the BCU LED changes from
“Green (blinking)” to “Green (ON)”. Otherwise, the device might be damaged:
 Initial power entry (with the memory card mounted) after the device is unpacked or
 During a software update.
 When moving the device, do not hold the handle of a power supply. These handles are not
intended for this purpose and could break off, causing the power supply 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 modules from a GR4000 or GS4000 into devices other than another
GR4000 or GS4000. Doing this could cause a fire or an electric shock.

 When detaching the AC power supply from GR4000-320E (AC) and GS4000-320E (AC), or the
DC power supply 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

GS4000 Quick Start Guide, Revision 3
QSGGS4KX10-00 5794092-2X xvii
 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 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.

1.1 How to Use GS4000
This section describes about the usage of GS4000. Read the instructions written here well before starting to use GS4000. The
following cases are possible as the major usages of GS4000.
1. Working GS4000 as a layer 2 switch using one VLAN
2. Working GS4000 as a layer 2 switch using more tnan one VLANs
3. Working GS4000 as a layer 2 or layer 3 switch by setting an IP address for VLAN
In this section, the overviews related to the usage 1 to 3 above are given.
NOTE GS4000 can be used as a router. See the section “8.4 Details About GS4000 Operations” if you
want to use it as a router.
As shown in Figure 1-1 below, you can start communications through GS4000 only by connecting interface cables
to it without setting configuration information in case that you use only one VLAN.
