Modules
The RG-S5750-S series switches support the following modules: M5000E-02SFP/GT, M5000E-01XS and M5000E-02XS.
The M5000E-02SFP/GT module provides two 1000M fiber/copper combo ports. The 1000M copper port is the
10/100/1000M adaptive RJ45 port supporting the cat-5 UTP and STP; while the 1000M fiber port supports only the
100/1000Base-X mode, and it can be used together with multiple types of optical transceiver modules of Ruijie
Networks for different transmission distances. When you use this module for the RG-S5750-S series switches, the
1000M fiber ports support the SFP Bi-Directional (BIDI) module. For information about the supported SFP BIDI
modules and relevant usage, see the Appendix B.
M5000E-01XS provides a 10G SFP Plus port module and support the 10GBASE-SR/LR/LRM model. It can be used
with various optical transceiver modules of Ruijie Networks for different transmission distances. This module
supports one-meter or three-meter SFP Plus passive copper cable on the RG-S5750-S series switches. It can be
used together with XG-SFP-CU1M and XG-SFP-CU3M copper cable transceiver modules of Ruijie Networks.
The M5000E-02XS provides two 10G SFP Plus ports and supports the 10GBASE-SR/LR/LRM mode. It can be used
together with multiple types of optical transceiver modules manufactured by Ruijie Networks to adapt different
transmission distances. This module supports one-meter or three-meter SFP Plus passive copper cable on the

Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in the case of an accident.
Do no maintain the switch that is powered-on alone.
Make sure that the power is turned off when necessary.
Do not place the equipment in a damp place. Do not let any liquid enter the chassis.
Any non-standard and impropriate electric operations may cause an accident such as a fire or electrical
shock, thus causing severe even fatal damage to human bodies and equipment.
Direct or indirect touch through a wet object on high-voltage and commercial electricity may bring a fatal
danger.
Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
Connect the device's circuit to the ground.
Clear up the dust.
Maintain the proper humidity.
Laser
Among the modules supported by the RG-S5750-S series, many are Class I laser products. Therefore, pay attention to
the following when using them:
When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered with a dust
cap, to keep out dust and avoid burning your eyes.
Do not approach or stare into any optical port, as this may cause permanent damage to your eyes.
Installation Site Requirements
The RG-S5750-S series must be used indoors. To ensure its functioning and prolong its service life, the installation site
must meet the following requirements.
Ventilation Requirements
RG-S5750-S should be placed at least 10cm away from surrounding walls to effective ventilation and heat dissipation.
Cables should be bunched or put on the cable frame after being connected in order to prevent blocking the air intake.
Dust the device every three months to avoid blocking the ventilation openings.
Temperature and Humidity Requirements
The temperature and humidity in the room must be stable to ensure the device's proper functioning and prolong its
service life.
Continuous improper temperature and humidity will cause damage to the device.
High relative humidity will reduce the insulation of insulation materials and cause electric leakage. Sometimes it may
lead to changes in the mechanical characters of materials and rust metal components.
Low relative humidity will dry the insulation sheets and generate static electricity, which will damage the electric circuits
of the device.
High temperature will large affect the device's reliability, shorten its service life and accelerate its aging.
T
able 2-1 Temperature and humidity requirements of the RG-S5750-S series
Temperature Relative Humidity
0–50ºC 10%–90%
The working temperature and humidity are measured 1.5 m above the ground and 0.4 m away from the
front plat and when the chassis's front and rear protective plates are removed.
Cleanness Requirements
Dust poses the top threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the use life of the equipment, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.
Table 2-2
Substance Concentration Limit (particles/m3)
Dust particles (diameter ≥0.5μm) ≤3.5×106
Dust particles (diameter ≥5μm) ≤3×104
Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements; as such
poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room
should be protected from the intrusion of harmful gases (for example, SO
2
, H2S, NO2 and Cl2), whose requirements are
listed in the following table.
Table 2-3
Gas Average (mg/m3) Maximum (mg/m3)
SO2 0.3 1.0
H2S 0.1 0.5
NO2 0.5 1.0
Cl2 0.1 0.3
The Average refers to the average limit of harmful gas in one week. The Maximum value is the upper limit
of the harmful gas measured in one week for up to 30 minutes every day.
EMI
The switch is vulnerable to external interface caused by capacity coupling, inductance coupling, electromagnetic wave
radiation, common impedance (including grounding system) coupling and conducting wires (including power cords,
signal and output wires).
Therefore, the following points should be noted:
The AC power supplying system is the TN system. The single-phase three-wire socket with protecting grounding
must be used as the socket for the power supply to enable the device’s upper filter circuit to effective filter the
power interface.
The switch
should be far from high-power radio transmitting stations, radar stations and high-frequency and
large-current devices.
Electromagnetic shielding methods should be applied when necessary, such as using the shielded cable as the
interface cable.
Cables must be connected to interfaces inside the room to prevent damage to the device’s signal ports caused by
over-voltage and over-current generated by thunder and lightning.
System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S5750-S series, preventing
lightning stroke and resisting interference. Please carefully check the grounding conditions on the installation site
according to the grounding requirements, and perform grounding operations properly as required.
The correct connection of grounding lines guarantees the lighting and interference resistance of switches
and must be performed with precision.
Safety Grounding
The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when the insulating resistance decreases the power supply and the enclosure in the equipment, electric shock may
occur.
The building must provide protective grounding connection to ensure that the device is connected to the
protection location.
The installation and maintenance personnel must check whether the A.C. socket is well connected to the
protection location of the building, if not, they should use a protective grounding wire to connect the
grounding end of the A.C. socket to the building's protection location.
The power supply socket must be installed in a place that is near to the device and where users can
operate the device easily.
Before the installation of the device, make sure that ground connection is connected at first and
disconnected finally.
The sectional area of the protective grounding wire should be at least 0.75 mm
2
(18 AWG)
Use the 3-core power supply line. The sectional area of each pin should be at least 0.75 mm
2
or 18 AWG.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, downlead
conductor and the connector to the grounding system, which usually shares the power reference ground and
yellow/green safety cable ground. The lightning discharge ground is for the facility only, but unnecessary for equipment.
EMC Grounding
The grounding required for EMC design includes shielding grounding, filter grounding, noise and interference
suppression, and level reference. All the above constitute the comprehensive grounding requirements. The grounding
resistance should be less than 1Ω. The RG-S5750-S backplane has one grounding pole.
Figure 2-1 Grounding of the RG-S5750-S
Lightning Resistance
When the AC power cable is imported outdoors and directly connected to the power port of the switch, lightning
preventing wires should be adopted to prevent the switch from being hit by lightning shocks. The lightning preventing
wires can be fixed on the cabinet, work station, or the equipment room’s wall through line buckles and screws. In
applications, the AC current first enters the lightning preventing wires and then the switch.
The lightning preventing wires are not provided and should be purchased by users as required. For the
usage of lightning preventing wires, refer to their manuals.
EMI Consideration
All kinds of interference, from inside or outside of the device or application system, create impacts on the device by
transmission of capacity coupling, inductance coupling and electromagnetic waves.
Electromagnetic interference can be divided into two categories by transmission types, namely i.e. radiated interference
and conducted interference.
Power, normally RF power, transmitted from a device through space to a sensor is called radiated interference. The
origin of the interference source can either be part of or a unit separated electrically from the interfered system.
Conducted interference is transmitted through magnetic wires or signal cables from the source origin to sensors.
Generally, conducted interference affects the power supply of a device and can be controlled by a wave filter. Given
that radiated interference can interrupt any signal paths of the device, it is difficult to shield the device from such
interference.
The power supplying system should be effectively protected by an electricity shield.
Grounding devices of power supply power supplying equipment and anti-lightening grounding devices should be
used in the working area of switch and should be deployed far away from switch.
The switch should be placed far away from high-power radio transmitting stations, radar stations and
high-frequency and large-current devices.
Electrostatic shielding methods should be applied.
Precautions for Fiber Connections
Before you connect the fibers, check that the optical connector type and fiber type match the optical interface type used.
In addition, pay attention to the Tx and Rx directions of the fiber. The Tx end of this device should be connected to the
Rx end of the peer device, and the Rx end of this device to the Tx end of the peer device.
