Chapter 2  Installation Preparation

2.1  Precautions

To avoid any device impairment and body injury resulting from improper use, please take the following precautions:

l           Before cleaning the switch, disconnect the power. Do not clean the switch with wet cloth or liquid.

l           Keep the switch away from water or dampness. Prevent water or moisture from entering the switch chassis.

l           Do not place the switch on an unstable case or desk, because the switch might be damaged severely in case of a fall.

l           Keep the switch room drafty and the switch ventilation hole free of obstruction.

l           The switch can operate normally only under correct voltage input. Make sure that the operating voltage is consistent with that labeled on the switch.

l           To prevent electric shock, do not open the chassis while the switch is operating, and do not open the chassis arbitrarily even when the switch is powered off.

l           Before changing interface cards, wear an ESD-preventive wrist strap to prevent the cards from being damaged by electrostatic discharge.

2.2  Requirements on Environment

S3100 Series Ethernet Switches must be used indoors. When you install your switch in a cabinet or on a desk, you must ensure:

l           Enough space is reserved near the air-intake hole and the ventilation hole of the switch for heat dissipation of the switch chassis.

l           The cabinet or the workbench takes good ventilation and heat dissipation system.

l           The cabinet or the desk is solid enough to bear the weight of the switch and the accessories.

l           The cabinet or the desk is well grounded.

To ensure normal operation and to prolong the life span of the switch, the following requirements on the installation site must also be satisfied.

2.2.1  Temperature/Humidity Requirements

You should keep your equipment room within the proper temperature and humidity ranges to ensure the normal operation and working life of your switch. If the humidity in the equipment room is too high for a long time, it may decrease the insulation attribute of insulating material or even cause electric leakage of insulating material, and, sometimes, may change the mechanical performance of material and cause the rustiness and corrosion of metal parts. If the relative humidity is too low, the captive screws may become loose due to the shrinking of insulation washers; in addition, electrostatic is more likely to be produced in a dry environment, which may damage the circuit of the switch. High temperature may cause even greater damage to the switch. High temperature for a long time will speed up the aging of insulation material, greatly lower the reliability of the switch and greatly reduce the life span of the switch.

For the temperature and humidity requirements of different models, refer to section 1.3  “Technical Specifications”.

2.2.2  Cleanness Requirements

Dust is a potential hazard to the safe operation of the switch. Falling on the equipment, it may cause electrostatic adsorption, and hence result in poor contact of the metal connectors or connection points. This is more likely to happen when the indoor relative humidity is low; in this case, it may not only shorten the device’s working life, but also incur communication failure. The requirements on dust content and particle diameter in the equipment room are shown in the following table.

Table 2-1 Requirements on dust content in the equipment room

Physical active substance	Unit	Content
Dust particle	particle/m³	≤ 3 x 104 (No visible dust on desk in three days)
Note: Dust particle diameter ≥ 5µm

 

Besides the requirements on dust, rigorous requirements are also set on the content of chloride, acid, and sulfide in the air of the equipment room. These kinds of harmful gas will accelerate metal corrosion and aging of certain parts. The equipment room should be protected from the intrusion of harmful gases such as SO₂, H₂S, NH₃ and Cl₂. The limits of these kinds of harmful gas are shown in the following Table.

Table 2-2 Limits on harmful gas in the equipment room

Gas	Max content (mg/m³)
SO2	0.2
H2S	0.006
NH3	0.05
Cl2	0.01

 

2.2.3  Anti-interference Requirements

A switch in use may be affected by the interference from outside the system by way of capacitance coupling, inductance coupling, electromagnetic radiation, public impedance (including the grounding system) coupling or conducting line (power line, signaling line and transmission line). Therefore, you should pay attention to the following:

l           If AC supply system is TN system, AC power socket should be a single-phase three-line power socket with Protection Earth (PE) so that the filter circuit on the equipment can effectively filter out the interference coming from the power supply system.

l           Keep the switch far away from high-power radio transmitters, radars, and high-frequency heavy-current devices.

l           Adopt electromagnetic shielding measure if necessary. For example, you can adopt shielded interface cable.

l           Wire interface cables indoors. Do not wire cables outdoors in case that overvoltage and overcurrent damage the device.

2.2.4  Laser Usage Security

S3100 series are category-1 laser equipment.

When an optional optical interface card of the S3100 series is operating, it is prohibited to stare into the optical interface because the laser beam emitted from the optical fiber takes high energy and may hurt your retina.

 

 

2.3  Installation Tools

l           Phillips screwdriver

l           Flat-blade screwdriver

l           ESD-preventive wrist strap

 

 

Chapter 3  Installation

 

 

3.1  Installing a Switch

3.1.1  Cabinet Mounting

You can install a switch into a 19-inch standard cabinet in one of the following four ways:

l           Use front mounting ears

l           Use front mounting ears and a tray

l           Use front mounting ears and rear mounting ears

l           Use front mounting ears and guide rails

The installation methods of a switch depend on the depth and width of the switch. For the specific installation methods, see Table 3-1 and Table 3-2.

Table 3-1 Installation methods for a switch with a width of 440 or 436 mm (17.3 or 17.2 in)

3.3.3  Connecting Grounding Cable

 

 

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 (commonly known as PGND). This chassis ground must be securely connected to the earth so that the faradism and leakage electricity can be safely released to the earth, enhancing the EMS capability of the switch.

Ground your switch as follows:

l           When a grounding strip is available at the installation site, attach one end of the yellow-green grounding cable of the switch to the grounding screw on the grounding strip and fasten the captive nut. (Note that the fire main and lightning rod of your building are not suitable for grounding the switch. The grounding cable of the switch should be connected to the construction engineering ground of the equipment room.)

Chapter 4  Lightning Protection of the Switch

4.1  Installation of Lightning Arrester for AC Power (Socket Strip with Lightning Protection)

 

 

If an outdoor AC power cord should be directly led to the switch, please serially connect the lightning arrester for AC power (Socket Strip with Lightning Protection) before you plug AC power cord into the switch, thus to prevent the possible damage to the switch due to lightning strike. You can use cable clips and screws to fasten the lightning arrester for AC power on the cabinet, workbench or the wall of equipment room.

Figure 4-1 Diagram of lightning arrester

 

 

4.2  Installation of Lightning Arrester for Network Port

 

 

 

If an outdoor network cable should be led to the switch, please serially connect the lightning arrester for network port before you plug this cable into the interface on the switch, in case of the possibility that the switch may be damaged due to lightning strike.

I. Required tools

l           Phillips screwdriver or Flat-blade screwdriver

l           Multimeter

l           Tilted cable cutter

II. Installation procedure

Step 1: Tear the protection paper at one side of the double faced adhesive tape apart from the tape, and stick the tape on the surface of the arrester. Tear the protection paper at another side apart from the tape, and stick the arrester onto the chassis of the switch. The arrester should be attached on the chassis as close to the grounding screw as possible.

Step 2: According to the distance to the grounding screw of the switch, cut the ground cable of the arrester, and securely tightening its ground cable to the grounding screw of the switch.

Step 3: Use the multimeter to measure whether the ground cable of the arrester contacts well with the grounding screw of chassis.

Step 4: According to the instruction of arrester for network port, connect the arrester with switch by the cables (be carefully with the cable direction. Outdoor network cable should be inserted into the arrester‘s IN end, and the cable connected to the switch should be inserted into the arrester’s OUT end). When you do that, observe whether the arrester indicators normally display.

 

 

Step 5: Use the nylon ties to bundle the cables neatly.

Figure 4-2 Installation diagram of lightning arrester for network port

III. Installation precautions

Fully consider the following items in the installation process, otherwise, the performance of the lightning arrester for network port will be affected:

l           Lightning arrester for network port is installed in reverse direction. In practice, the “IN” end should be connected to the outdoor network cable and the “OUT” end to the network port on the switch.

l           Lightning arrester for the network port is not well grounded. The ground cable for the arrester should be as short as possible, so to ensure its good contact with the grounding screw of the switch. After the connection, use the multimeter to confirm that.

l           The lightning arrester for the network port is not installed completely. If the switch has more than one network ports to interconnect with other devices via cables outdoor, you should install lightning arresters for all these network ports for protection.
