Chapter 2  Installation Preparation

2.1  Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

l           Before cleaning the switch, unplug the power plug of the switch first. Do not clean the switch with wet cloth or liquid.

l           Do not place the switch near water or any damp area. Prevent water or moisture from entering the switch chassis.

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

l           Ensure proper ventilation of the equipment room and keep the ventilation vents of the switch free of obstruction.

l           Make sure that the operating voltage is the same one labeled on the switch.

l           Do not open the chassis while the switch is operating or when electrical hazards are present to avoid electrical shocks.

l           When replacing interface cards, wear ESD-protective gloves to avoid damaging the cards.

2.2  Installation Site

The S5510 series must be used indoors. You can mount your switch in a rack or on a tabletop/workbench, but make sure:

l           Adequate clearance is reserved at the air inlet/exhaust vents for ventilation.

l           The rack or table/workbench has a good ventilation system.

l           The rack is sturdy enough to support the device and its accessories.

l           The rack or table/workbench is well earthed.

To ensure normal operation and long service life of your VG, install it in an environment that meets the requirements described in the following subsections.

2.2.1  Temperature/Humidity

You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity may lead to bad insulation, electricity leakage, mechanical property changes, and corrosion. However, if the relative humidity is two low, captive screws may become loose as the result of contraction of insulation washers and static electricity may be produced in a dry environment to jeopardize the CMOS circuits on the device. High temperature is the most undesirable condition, because it accelerates aging of insulation materials and can thus significantly lower reliability and service life of your switch.

For the temperature and humidity requirements of different models, refer to section 1.5  Technical Specifications of S5510 Series.

2.2.2  Cleanness

Dust is a hazard to the operating safety of your device. The dust accumulated on the chassis can be adsorbed by static electricity and result in poor contact of metal connectors or metal contact points. This can not only shorten the service life of your device but also cause communications failures. When the relative indoor humidity is low, electrostatic adsorption is more likely to happen. The contents of the dust must be limited as shown in the following table:

Table 2-1 Dust content limits in an equipment room

Substance	Unit	Concentration limit
Dust	Particles/m³	≤ 3 X 104 (No visible dust on the tabletop for three days)
Remark: the diameter of a dust particle ≥ 5μm

 

Besides dust, there are rigorous limits on the harmful gases that can accelerate the erosion and aging of metals, such as salts, acids, and sulfides, as shown in the following table.

Table 2-2 Harmful gas limits in the equipment room

Gas	Maximum concentration (mg/m3)
SO2	0.2
H2S	0.006
NH3	0.05
Cl2	0.01

 

2.2.3  Electromagnetic Susceptibility

The operation of your switch can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance (including the grounding system) coupling, and leads (power cords, signaling cables and output wires. To eliminate the interferences, make sure to:

l           For the AC power supply that adopts TN system, use a monophase three-line power socket with Protection Earth (PE) to effectively filter interference from the power grid.

l           Keep the device far from radio transmitting stations, radar stations, and high-frequency devices.

l           Use electromagnetic shielding when necessary, for example, use shielded interface cables.

l           Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.

2.2.4  Laser Safety

The S5510 series are class-1 laser devices.

When the optical ports on your switch are operating, do not stare into the optical ports because the laser light emitted by the optical fiber can hurt your retina.

 

 

2.3  Installation Tools

l           Flat-blade screwdriver

l           Phillips screwdriver

l           ESD-preventive wrist strap

When a 19-inch standard cabinet is not available, you can simply place the switch on a clean desk. When doing so, you should ensure that:

l           The desk is stable and well grounded.

l           A clearance about 10 cm (3.9 in) is reserved around the switch for heat dissipation.

l           No heavy object is placed on the switch.

3.2  Installing Power Module

 

 

3.2.1  Installing a Power Module

Step 1: Draw on the ESD-preventive wrist strap and ensure that the strap is well grounded.

Step 2: Remove the dummy panel from the power slot.

Step 3: Keeping the power module to be installed in the right direction, with one hand taking hold of the handle before the module and the other hand holding the module on the palm, smoothly slide the module into the power slot until the plug on the module completely fits into the socket in the chassis. Note that, the right direction is that the letters on the module is in the up direction; if you install the module with upset down, being restricted by the specially-designed structure inside the chassis, you will not be able to completely insert the module into the slot.

Step 4: Fasten the captive screws at both sides of the power module with a Phillips screwdriver.

3.2.2  Removing a Power Module

Step 1: Draw on the ESD-preventive wrist strap and ensure that the strap is well grounded.

Step 2: Power down the module to be removed.

Step 3: Loosen the captive screws at both sides of the power module with a Phillips screwdriver.

Step 4: With one hand taking hold of the handle before the power module to be removed and the other hand press down on the top of the switch, pull the module completely out off the socket in the chassis and smoothly out of the power slot.

 

 

3.3  Connecting the Power Cord and the Ground Wire

3.3.1  Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)

You are recommended to use a monophase three-line power socket with a ground contact or a general purpose PC power socket, making sure that the power point is well connected to building ground. Normally, the ground point of the power source in a building was buried in the ground during the construction and wiring. Still, you must make sure of that.

Figure 3-14 Power socket (recommended)

II. Connecting the AC-input power cord

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear of the chassis and the other end to the ground as near as possible.

Step 2: Connect one end of the power cord to the power socket on the rear of the chassis, and plug the other end to the AC power jack of the power source.

Step 3: Verify that the PWR LED on the front panel of the switch is ON.

 

 

3.3.2  Connecting the DC-Input Power Cord

+: -48V working ground

-: -48 to -60 V

NULL: reserved

Figure 3-15 DC-input power connector (partial)

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear of the chassis and the other end to the ground as near as possible.

Step 2: Directly insert the component into DC-input socket on the cabinet, and then fix the screws 1 and 2 carried by the connector itself to the appropriate holes on the cabinet socket using a small flathead screwdriver, see Figure 3-16.

Figure 3-16 Illustration for fixing RPS connector to the cabinet

Step 3: Verify that the power LED PWR1/PWR2 on the front panel of the switch is ON.

 

 

3.3.3  Connecting the Ground Wire

 

 

The power input end of the switch is connected with a noise filter, whose central ground is directly connected to the chassis, forming the chassis ground (commonly known as PGND). This chassis ground must be securely connected to the earth ground so that the faradism and leakage electricity can be safely released to the ground, 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 ground wire 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 a building are not suitable for grounding the switch. The ground wire of the switch should be connected to the grounding device for the equipment room.)

(3) Ground wire	(4) Grounding strip

Figure 3-17 Grounding the switch through a grounding strip

l           When there is no grounding strip but earth near the equipment room that allows a grounding body to be buried, hammer an angle iron/steel pipe longer than 0.5 m into the earth, weld the yellow-green ground wire of the switch onto the angle iron/steel pipe, and process the joint against erosion.

3.5.2  Connecting the Console Cable

Follow these steps to connect a terminal device, a PC for example, to the switch:

Step 1: Plug the DB-9 (female) connector of the Console cable to the serial port of the PC where the switch is to be configured.

Step 2: Connect the RJ-45 connector of the console cable to the Console port of the switch.

 

 

 

3.6  Verifying Installation

l           The correct power source is used.

l           The ground wire is securely connected.

l           Both of the console cable and power cord are correctly connected.

l           All the interface cables are routed indoors. If there are cables outdoors, verify that the socket strip with lightning protection and lightning arresters for network ports have been correctly connected.

 

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.

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 wire 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 wire of the arrester, and securely tightening its ground wire to the grounding screw of the switch.

Step 3: Use the multimeter to measure whether the ground wire 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.

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:

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.

Lightning arrester for the network port is not well grounded. The ground wire 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.

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.
