The following safety suggestions do not cover all possible dangers.
2.1.1 Safety Precautions for Installing the System
Keep the chassis clean and free from any dust.
Do not place the equipment in a walking area.
Do not wear loose clothes or any other things that may be caught by the chassis during installation and
maintenance.
Turn off all power supplies and remove the power sockets and cables before dismantling the cabinet.
2.1.2 Movement Safety
Do not frequently move the device.
When moving the device, note the balance and avoid hurting legs and feet or straining the back.
Before moving the device, turn off all power supplies and dismantle all power modules.
2.1.3 Electric Safety
Observe local regulations and specifications when performing electric operations. Relevant operators must be
qualified.
Carefully check any potential danger in the working area, such as ungrounded power supply, unreliable
grounding of the power supply, and damp/wet ground or floor.
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.
Try to avoid maintaining the switch that is powered-on alone.
Be sure to make a careful check before you shut down the power supply.
Do not place the equipment in a damp location. Do not let any liquid enter the chassis.
1. Any nonstandard and inaccurate electric operation may cause an accident such as fire or electrical shock,
thus causing severe even fatal damages to human bodies and equipment.
2.Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.

2.1.4 Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
1.Proper grounding of the equipment and floor
2.Indoor dust prevention
3.Proper humidity conditions
2.1.5 Laser Safety
Among the modules supported by the RG-S2924GT/8SFP-XS-P, a great number of optical modules are Class I
laser products. Therefore, pay attention to the following when you use 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 stare into any optical port.
Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
The RG-S2924GT/8SFP-XS-P must be used indoors. To ensure the normal working and a prolonged durable life of
the equipment, the installation site must meet the following requirements.
2.2.1 Ventilation Requirements
For the RG-S2924GT/8SFP-XS-P, you must ensure that sufficient space(at least 10cm distance from both sides and
the backplane of the cabinet) is reserved at the ventilation openings to ensure the normal ventilation. After various
cables have been connected, they should be arranged into bundles or placed on the cabling rack to avoid blocking
the air inlets.
2.2.2 Temperature and Humidity Requirements
To ensure the normal operation and prolong the service life of RG-S2924GT/8SFP-XS-P, you should keep proper
temperature and humidity in the equipment room.
If the equipment room has temperature and humidity that do not meet the requirements for a long time, the
equipment may be damaged.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. Sometimes the materials may suffer from mechanical performance change and metallic parts may
get rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity
may occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance
may degrade significantly and its useful life may be shortened in the case of long-term exposure that
expedites the aging process.
Therefore, the ambient temperature and humidity of the RG-S2924GT/8SFP-XS-P must meet the requirements
listed in Table 2-1:
Table 2-1 Temperature and humidity requirements of the RG-S2924GT/8SFP-XS-P

Temperature Relative Humidity
0ºC-50ºC 10%-90%
The ambient temperature and humidity are measured at the point that is 1.5 m above the floor and 0.4 m before the
equipment when there is no protective plate in front or back of the equipment rack.
2.2.3 Cleanness Requirements
Dust poses a severe 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 useful life of the equipment, but also causing
communication faults. Table 2-2 shows the requirements for the dust content and granularity in the equipment room.
Table 2-2 Requirements for the dust content and granularity in the equipment room
Maximum diameter (μm) 0.5 1 3 5
Maximum density (Particles/m3) 1.4 x 10 7 x 10 2.4 x 10 1.3 x 10
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 such as sulfur dioxide, sulfured hydrogen, nitrogen
dioxide, and chlorine), whose requirements are listed in Table 2-3.
Table 2-3 Requirements for harmful gases in the equipment room
Gas Average (mg/m3) Maximum (mg/m3)
Sulfur dioxide 0.2 1.5
Sulfured hydrogen 0.006 0.03
Nitrogen dioxide 0.04 0.15
Ammonia 0.05 0.15
Chlorine 0.01 0.3
2.2.4 EMI
During applications, the switch may be subject to external interferences that affect the device through conduction
manners such as capacitance coupling, inductive coupling, electromagnetic wave emission, common impedance
(including grounding systems), and wires (power cables, signal cables and outgoing transmission cables). For that
purpose, note that:
For the AC power supply system TN, single-phase three-core power socket with protective earthing
conductors (PE) should be adopted to effectively filter out interference from the power grid through the
filtering circuit.
The switch should be located at places free from large power radio launch pad, radar launch pad, and
high-frequency large-current devices.
If necessary, electromagnetic shielding should be adopted. For example, use interface cables to shield
cables.
Interface cables should be laid inside the equipment room. Outdoor cabling is prohibited, avoiding damages
to device signal interfaces caused by over-voltage or over-current of lightning.

2.3 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S2900E series. It is the chief
condition to prevent lightning stroke and resist 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.
2.3.1 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.
2.3.2 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, irrelevant to the equipment.
2.3.3 EMC Grounding
The grounding required for EMC design includes shielding ground, filter ground, noise and interference suppression,
and level reference. All the above constitute the comprehensive grounding requirements.The grounding resistance
should be less than 1 ohm. The RG-S2924GT/8SFP-XS-P backplane is reserved with one grounding pole, as
shown in 0.
Figure 2-1 Schematic diagram of the RG-S2924GT/8SFP-XS-P grounding
2.4 Lightning Resistance Considerations
When the AC power cable is imported outdoors and directly connected to the power port of the switch, lightning line
bank should be adopted to prevent the switch from being hit by lightning shocks. The lightning line bank can be fixed
on the the cabinet, work station, or the equipment room's wall through line buckles and screws. In applications, the
AC first enters the lightning line bank and then the switch.
1The lightning line banks are not provided and should be purchased by users as required.
2For the usage of lightning line banks, refer to their related manuals.

2.5 EMI Consideration
Various interference sources, from either outside or inside the equipment or application system, affect the system in
the conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation.
There are two types of electromagnetic interferences: radiated interference and conducted interference, depending
on the type of the transmission path.
When the energy, often RF energy, from a component arrives at a sensitive component via the space, the energy is
known as radiated interference. The interference source can be either a part of the interfered system or a completely
electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection
between the source and the sensitive component, along which cable the interference conducts from one unit to
another. Conducted interference often affects the power supply of the equipment, but can be controlled by a filter.
Radiated interference may affect any signal path in the equipment and is difficult to shield.
1.Effective measures should be taken for the power system to prevent the interference from the electric grid.
2.The working ground of the switch should be preferably separated and kept as far as possible from the grounding
device of the power equipment or the anti-lightning grounding device.
3.Keep the equipment away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
4.Measures must be taken to shield static electricity.
2.6 Precaution 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 equipment should be
connected to the Rx end of the peer equipment, and the Rx end of this equipment to the Tx end of the peer
equipment.
2.7 Precaution for Power Module Installation
The power module installation is needed for the RG-S2924GT/8SFP-XS-P switches, as shown in Figure 2-2:
Figure 2-2 Schematic diagram of the RG-S2924GT/8SFP-XS-P power module installation

The power module is hot-swappable. It’s recommended to disable all power switches when plugging in/out the
power module and enable the switch with the power module inserted and installed.
