intended primarily for high-speed interconnection of enterprise networks and Gigabit
applications to desktop. When used in Metropolitan Area Network (MAN), they can
provide MAN convergence with multi-port Gigabit optical ports.
The following are the models that S5000 Series can provide by far.
S5012G: It is powered by AC supply and provides 12 10/100/1000BASE-T
auto-negotiation Ethernet ports (RJ-45 connector) and 4 Combo GBIC (Gigabit
Interface Converter) ports.
S5012G-DC: It is powered by DC supply. Its port configuration is identical with that of
the S5012G.

Note:
zThe following describes the meaning of a Combo port:
Take S5012G Ethernet Switch as an example, Combo GBIC port (numbered 9+) and its
corresponding 10/100/1000BASE-T Ethernet port (numbered 9) are optional in optical
or electronic type. The user can select one from them according to real networking
environment. But these two ports cannot work simultaneously. Besides, only the
Ethernet port is in the valid operating state when the two ports are all connected. In the
same way, for the switch S5012T-12/10GBC, Combo RJ45 port and its corresponding
GBIC port are also optional in optical or electronic type. Only the Combo RJ45 port is in
the valid operating state when the two ports are connected.
zGBIC is a kind of hot-swappable data communication connector.
Note:
S5012G and S5012G-DC switches share similar structures, except for their power
sockets. Unless otherwise specified, S5012G is introduced as a representative.
For the same reason, S5012T is introduced as a representative of S5012T-12/10GBC
and S5012T-12/10GBC-DC; S5024G is introduced as a representative of
S5024G-24/20TP and S5024G-24/20TP-DC.

Chapter 2 Installation Preparation
2.1 Safety Requirements
To avoid any device impairment and bodily injury because of improper uses, please
follow the precautions listed below:
zBefore cleaning the switch, please unplug the switch connector first. Do not clean
the switch with wet cloth or with liquid.
zDo not place the switch near water or any damp area. Prevent water or moisture
from entering the switch chassis.
zDo not place the switch on the unstable cases or desks, as the switch might be
damaged severely in case of a fall.
zEnsure proper ventilation of the room and keep the switch ventilation hole free of
obstruction.
zThe switch can operate normally under correct voltage input. Make sure that the
operating voltage is consistent with that labeled on the switch.
zDo not open the chassis while the switch is in operation to protect the safe of the
operator and the switch.
2.2 Examine Installation Location
S5000 Series can only be used indoors. The following conditions must be met
regardless of whether you install the switch in 19-inch standard rack or directly on the
tabletop.
zMake sure that enough room is left for the air-intake hole and the ventilation hole
of the switch, so that the heat dissipation of the switch chassis can be guaranteed.
zMake sure that the ventilation and heat dissipation systems of the rack and the
tabletop are good.
zMake sure that the rack and the table are stable enough to bear the weight of the
switch and the accessories.
zMake sure that the rack and the table are well grounded.
2.2.1 Temperature/Humidity Requirements
To ensure the normal operation and service lifetime of a switch, proper temperature
and humidity should be maintained in the equipment room. Long-lasting high humidity
in the equipment room is prone to poor insulation or even creepage of the insulating
material. Sometimes, the mechanical performance deterioration, the rustiness and
corrosion of some metal parts are also more likely to occur. If the relative humidity is too
low, the captive screws may become loose due to the insulation washer contraction.

Installation Manual
Quidway S5000 Series Ethernet Switches Chapter 2 Installation Preparation
Huawei Technologies Proprietary
2-2
Meanwhile, the electrostatic is likely to be produced in the dry environment, which will
jeopardize the CMOS circuit of the switch. The higher the temperature, the greater the
damage it will do to the Switch. Long-lasting high temperature will speed up the aging
process of the insulating materials, greatly lower the reliability of the switch, and
therefore affect its service life seriously.
2.2.2 Cleanness Requirements
Dust is a hazard to the operating safety of the Switch. The indoor dust accumulated on
the chassis can cause electrostatic adsorption, which may result in the poor contact of
the connector or metal contact point. This happens more frequently when indoor
relative humidity is low, which will not only shorten the service life of the switch, but also
cause communication failure.
The required specifications on dust content and particle diameter in an equipment room
are shown in the following table.
Table 2-1 Limit on dust content in equipment room
Mechanical active
material Unit Content
Dust particle particle/m³ ≤3 x 104(No visible dust on desk in three
days)
Note: Dust particle Diameter ≥5µm
Besides the dust specifications, the equipment room of the Switch should also meet the
rigorous requirements for the content of salt, acid and sulfide. These harmful gases
could accelerate the metal erosion and the aging process of some parts. Incursion of
harmful gases, such as SO2, H2S, NO2, NH3, and Cl2, should be prevented. The specific
limitation values of these harmful gases are given in the following table.
Table 2-2 Harmful gas limits in an equipment room
Gas Max. (mg/m³)
SO20.2
H2S 0.006
NH30.05
Cl20.01
2.2.3 Anti-interference Requirements
Any possible interference sources, no matter outside or inside the system, affect the
Switch in use in a way of capacitance coupling, inductance coupling, radiation of

Installation Manual

2-3
electromagnetic wave, common impedance (including the grounding system) coupling
or conducting line (power line, signaling line and transmission line etc.). To prevent the
interference, you should:
zIf AC supply system is TN system, AC power socket should be a single-phase
three-line power socket with Protection Earth (PE). Thereby, the filtering circuit in
the equipment can effectively filter interference from the power supply system.
zKeep the switch far away from radio launcher, radar launcher, and high-frequency
devices working in high current.
zAdopt the measure of electromagnetic shielding if necessary. For example, you
can adopt shielded interface cable.
zInterface cable must be run indoors, and outdoor cabling is not permitted, in case
that over-voltage and over-current damage the device.
2.2.4 Laser Usage Security
S5000 Series belong to class-1 laser devices.
In operating status, it is prohibited to stare into the open optical port because the laser
being transmitted through the optical fiber will produces a small beam of light which has
very high power density and is invisible to human eyes. When a beam of light enters the
eye, retina may be burned.
Caution:
Staring at the laser beam inside the fiber could hurt your eyes.
2.3 Installation Tools
zPhillips screwdriver
zFlat-blade screwdriver
zESD-preventive wrist strap
Caution:
The installation tools are not shipped with S5000 Series. You will have to prepare them
beforehand.

Chapter 3 Installation
Caution:
On a mounting screw of Quidway series switches' chassis, there is an anti-dismantle
seal of Huawei Technologies. The seal must be kept intact before the sales agent
performs maintenance on the switch. Users should contact local agent for permission if
it is necessary to open the chassis. Otherwise, users will bear responsibility for possible
damages.
3.1 Installing the Switch
3.1.1 Racking-Mounting the Switch in 19-inch Rack
The switch can be mounted in a 19-inch standard rack. The installing procedure is
described below:
Step 1: Check grounding and stability of the rack. Fix the mounting brackets at both
sides of the front panel of the switch with screws.
Step 2: Place the switch on a shelf in the rack. Depending on the actual situation, slide
the switch along the guides of the rack to an appropriate position. Ensure there is
proper room between the switch and the guides.
Step 3: Use screws to fix the mounting ears on the fixing guides at both sides of the
rack. Make sure that the switch is securely fixed in the rack by the shelf on each slot
and the mounting ears.

Note:
The mounting ears are used for fixing rather than bearing. When mounted in a 19-inch
standard rack, the switch is borne by slide rails (fixed on the rack).
3.1.2 Free-Standing the Switch on a Tabletop
If you have no 19-inch standard rack, you may just place the switch on a clean tabletop,
which is a relatively easy way to operate. You need to pay attention only to the following
during such operation:
zMake sure that the table is stable and well grounded.
zLeave about 10 cm of space around the switch for heat dissipation.
zDo not place heavy objects on top of the switch.
3.2 Connection of Power Cord and Grounding wire
3.2.1 Connecting AC Power Cord
I. AC power socket (Recommended)
A monophase 3-wire power socket with a neutral point, or a multi-functional power
socket for the computer is recommended. The neutral point of the power in a building
must be reliably grounded. Normally, the neutral point of the power supply system in a
building is buried in the ground during the construction and wiring. Make sure that the
power supply for the building is grounded.

NEG(-): -48V RTN(+): -48V working ground
Figure 3-3 DC power socket
Step 1: Connect one end of the chassis group cable, which is attached to the switch in
delivery, to the grounding screw on the rear panel of the switch. Ground the other end to
the nearest connecting point.
Step 2: Connect the DC power terminals of the switch to the corresponding terminals of
the -48V DC power system with power cord, with NEG(-) to the -48V input and RTN(+)
to the working ground of the -48V power supply.
Note:
In connecting power cords to the DC power terminals of the switch, first screw off the
terminal screw and insert the power cord, then screw on it.
Step 3: Check the state of the PWR LED on the front panel. ON means the power cords
are connected correctly.
Caution:
You should first connect the grounding cable before powering on the switch.

3.2.3 Redundant Power Input (Optional)
Caution:
The redundant power cord is not hot-swappable.
I. Redundant power input
To make S5000 Series more reliable, redundant power module is provided. The
module has a 12V DC external port, which is connected to Huawei RPS (Redundant
Power System) through DC power cord. The RPS is an external AC-DC or DC-DC
transformer system.
The following figure illustrates the input socket of the redundant power of S5000 Series.

II. Connecting redundant power cord
Step 1: Make sure the switch has been powered off and the RPS DC output has been
turned off.
Step 2: Plug one end of the DC power cord of RPS into the redundant power socket on
the rear panel of the switch and the other end into the DC output socket of RPS.
Step 3: Turn on the switch power and RPS DC output.
Step 4: Check if the state indicator in RPS panel (OK) is on. On means RPS is working
normally. Check if the RUN indicator in the switch panel is blinking. Blinking means the
redundant power input of the switch has been correctly connected.

Caution:
The correct connection of the switch grounding wire is the primary guarantee for the
lightning protection and anti-interference; so users must connect the grounding wire
correctly.
Note:
The following figures just illustrate processing method of grounding screws or
grounding at power input end, but no switch type and accurate positions of power input
end and grounding screws are specified.
The power input end of the switch is connected with a noise filter, whose central ground
is directly connected to the chassis, forming the so-called chassis ground (also called
PE). This chassis must be well grounded so that the faradism and leakage electricity
can be safely released to the ground to enhance the switch capability of withstanding
electromagnetic interference. The switch should be grounded in the following way.
zIf there is grounding strip in the Ethernet switch installation environment, attach
one end of the yellow-green protection grounding wire to the grounding screw of
the grounding strip and fasten the captive nuts. Note that the fire main and
lightning rod of a building are not suitable for grounding the switch. The grounding
wire of a switch shall be connected to the grounding device of the equipment
room.

zIf there is no grounding strip but earth nearby and the grounding body is allowed to
be buried, you can simply hammer an angle steel or steel pipe no shorter than
0.5m into the earth. In this case, the yellow-green protection grounding wire
should be welded with the angle steel (steel pipe) and the joint should be
processed against eroding.
