z Turn off all powers and remove all the power cables before moving the chassis. z Do not move the switch alone. Work with another person. z Move the switch slowly and stably. Never move suddenly or twist your body. z Move the switch at stable and consistent paces with your peer. Keep balance of

your body.

3-1

Page 74

Installation Manual H3C S7502 Ethernet Switch Chapter 3 Installation Preparations

Caution:

Do not hold the power handles, but the handles on the rear of the chassis, or put fingers into the vent of chassis when moving the switch. Since the power handle and vent have not been designed to bear the weight of the entire chassis, it may hurt the switch chassis or even your body when you move the switch by handling them.

3.1.4 Anti-static Safety

To prevent the electric component from being damaged by the electrostatic discharge (ESD), take ESD measures for the area where the swit ch is located and pay attention to the following:

z Always wear an ESD-preventive wrist strap when installing the components,

especially the electric printed circuit boards, of the switch.

z Take the edge of the circuit board. Do not touch the components or the electric

printed circuit. Take the following steps to use the ESD-preventive wrist strap. Step 1: Put your hand through the wrist strap and wear it Step 2: Strain and tighten the strap, ensure that it makes good contact with your skin. Step 3: Insert it into the ESD-preventive wrist stra p ho le in the switc h cha ssis o r at t a ch

Page 75

Installation Manual H3C S7502 Ethernet Switch Chapter 3 Installation Preparations

3.1.5 Laser Safety

Some LPU of the S7502 has optical ports. In operating status, it is prohibited to stare into the open optical port because the laser emitted from it has very high power density and is harmful to your retina.

Caution:

Staring at the laser beam inside the fiber could hurt your eyes.

3.2 Examining Installation Site

The S7502 can only be used indoors. To ensure that the switch works normally and expand its service life, the installation environment shall meet the requirements described in the coming sections.

3.2.1 Temperature/Humidity Requirements

To ensure the normal operation and service life of a switch, a certain level of temperature and humidity should be maintained in the equipment room. If the humidity in the equipment room is too high and for a long time, it may go bad insulated or even power leakage may occur. Sometimes, high humidity may result in material mechanical performance changing or metal parts rusted. If the relative humidity is too low, the captive screws may become loose due to the shrinkage of the insulation washers. 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 on the switch. High temperature for a long time will speed up the aging process of the insulation materials, greatly lower the reliability of the switch and therefore affect its service life seriously.

Table 3-1 Temperature/humidity requirements

Specification Range

Operating temperature 0°C to 45°C (32°F to 113 °F) Relative humidity (noncondensing) 10% to 90%

3.2.2 Cleanness Requirements

Dust does serious harm to the normal operation of the switch. The indoor dust accumulated on the chassis can cause electrostatic adsorption, resulting in poor

3-3

Page 76

Installation Manual H3C S7502 Ethernet Switch Chapter 3 Installation Preparations

contact between connectors or metal contact points. This happens more frequently when the relative indoor humidity is low, which will not only shorten the service life of the switch, but also cause communication failures.

The required specifications on dust density and parti cle diameter in an equipment room are shown in the following table.

Table 3-2 Required specifications on dust density in an equipment room

Mechanical active

material

Concentration limit (particles/m³)

Dust particle ≤3 x 104 (No visible dust on desk over three days) Note: Dust particle diameter ≥ 5µm

Except the requirements on dust, rigorous requirements on ingredient of salts, acids and sulfides of air in an equipment room are also set. These harmful gases will speed up the metal corrosion and the aging processes of certain parts. The equipment room should be protected from the invasion of harmful gases such as SO and Cl

, the value limits of which are shown in Table 3-2:

, H2S, NO2, NH3

3.2.3 Anti-static Requirements

Any possible interference sources, no matter outside or inside the system, affect the switch in use may in a way of capacitance coupling, inductance coupling, radiation of electromagnetic wave, common impedance (including the grounding system) coupling or conducting line (power line, signaling line and transmission line etc.).Therefore, the following should be considered:

z Adopt effective measures to protect the power supply system against the power

grid interference.

z Separate the working ground of the switch from the ground device of the power

supply equipment or lightning-protection ground device as far as possible.

z Keep the switch far away from the radio launcher, radar launcher, and

high-frequency devices working in high current. If necessary, adopt electromagnetic shield.

3-4

Page 77

Installation Manual H3C S7502 Ethernet Switch Chapter 3 Installation Preparations

3.2.4 Grounding Requirements

A good grounding system is the basis for a switch to work stably and reliably and the important guarantee of lightning protection, anti-interference and ESD. A switch should be provided with good grounding system.

3.2.5 Power Supply Requirements

The S7502 provides 1+1 power redundancy backup. For AC power modules:

z Rated voltage range: 100 VAC to 240VAC, 50 Hz or 60 Hz z Input voltage range: 90 VAC to 264 VAC, 50 Hz or 60 Hz z Power output power: 300 W

For DC power modules:

z Rated voltage range: –48 VDC to –60 VDC z Input voltage range: –36 VDC to –72 VDC z Max output power: 296 W

3.3 Installation Planning

Since the S7502 is a kind of complex equipment, it is necessary to make a good plan and arrangement concerning installation position, networking measure, power supply and cabling before installing it.

3.3.1 Space Requirement

For better heat dissipation and equipment maintenance, it is recommended to keep the front and back of the switch more than 1 meters inclusive away from the walls or other devices. There can be other devices located beside the left and right of the switch. However, you shall keep the left and right of the switch more than 0.8 meters inclusive away from the walls. If the optional rack will be installed, the net height of equipment room should be more than 3 meters inclusive.

3.3.2 Rack-Mounting Requirements

Before rack-mounting a switch, make sure the rack meets the following requirements:

z Better mount a switch in an open rack. However, if you mount a switch in a closed

rack, make sure of good heat dissipation system.

z Make sure the rack stands steadily enough to well support the switch and

accessories.

z Make sure that the switch fits the rack size. Leave enough spaces beside the left

and right panels of the switch for chassis heat dissipation.

Fiber connectors are indispensable passive components in optical fiber communication

system. Their application enables the removable connection between optical channel,

which makes optical system debugging and maintenance more convenient and transit

dispatching more flexible. Among multiple fiber connectors, only SC, LC, and MT-RJ

will be introduced here.

z MT-RJ fiber connector: It integrates two channels of light sources into a single

fiber, which reduces the actual ports that are in use of a connector.

Figure 4-14 An MT-RJ connector

z SC fiber connector

z LC fiber connector

Figure 4-16 An LC connector

II. Connect an optical fiber

Step 1: Remove the protective cap from the connector and clean the fiber end.

Step 2: Remove the optical port cover of the switch. Insert one end of the fiber into the

optical port of the switch.

Step 3: Connect the other end of the fiber to the corresponding device.

Page 93

Installation Manual H3C S7502 Ethernet Switch Chapter 4 Hardware Installation

Caution:

When the optical port has not been connected with a fiber connector or its dustproof

cover is open, there might be some invisible radiation emitted from the optical port. So

do not stare into the optical port directly.

Cover the optical port if there is no connector plugged in.

4.7 Cabling

4.7.1 Table-Mounted Switch

If the chassis of a switch stands alone, you do not have to care about the inside or

outside cabinet cabling. All the port service cables can run along the left side of the

chassis (cabling channel), and the chassis power cables can run upward or downward

based on the specific conditions in the equipment room (lightning protection box,

terminal bar etc).

4.7.2 Rack-Mounted Switch

For the switches are mounted in a 19-inch standard rack, the service cables can be

bound to the cable binding rack at the left side of the chassis and be arranged to run on

the cable rack or in the raised floor according to the situation in an exchange equipment

room (whether the signal cable of the room is accessed from the cable rack on the top

of the chassis or the cable channel under the floor.) Collect all the transit data signal

cable connectors and locate them on the floor of the chassis instead of any places

outside the chassis for fear of unexpected damage. The power cables run out of the

rear left of the chassis and either on the cable rack or in the raised floor as near as

possible based on the specific conditions in the equipment room (lightning protection

box, terminal bar etc).

4.8 Cable Binding

4.8.1 Use of Labels

Correctly edit the label and paste it to a proper place on the bound cables.

4.8.2 Precautions for Cable Binding

z Bind the cables straight in the cabinet. No twisting or bending.

4-14

Page 94

Installation Manual H3C S7502 Ethernet Switch Chapter 4 Hardware Installation

Twisting

Bending

Figure 4-17 Cable binding example I

z The radius of the curve at which a cable is bent should be no less than twice of the

cable’s diameter. At the point where a cable runs out of a connector, the radius of

the curve at which the cable is bent should be no less than five times of its

diameter.

z Cables of different type (that is, power cable, signal cable, grounding cable, etc.)

should run and be bound separately in a cabinet. They cannot be bound together.

If they are close to each other, you can cable them in a crossing way. For parallel

cabling, the space between power cable and signal cable should be no less than

30mm;

z The cable binding rack and cable channel inside and outside a cabinet should be

smooth and stretch no sharp points.

z The metal hole through which a cable runs should have a smooth and fully surface

or an insulating bush;

z Use the right type of ties to bind the cables. Do not bind any cables with tied ties.

The following types of ties are provided: 100*2.5mm, 150*3.6mm, 300*3.6mm,

530*9mm, and 580*13mm;

z Bind the cables with ties and cut the extra parts. Trim the cut and leave no sharp

points. See the following figure:

4-15

Page 95

Installation Manual H3C S7502 Ethernet Switch Chapter 4 Hardware Installation

Figure 4-18 Cable binding example II

z Before bending the cables, bind them first. Mind that no tie binds the bended part

of any cables, for fear of cable core breaking due to excessive stress. See the

following figure.

Figure 4-19 Cable binding example III

z The spare cables or excessive parts should be folded and bound and located at

right places in a cabinet or on the cable channel. In the so-called right places, the

running device will not be affected or damaged and the cables will not be damaged,

either.

z 220V power cable and -48V power cable cannot be tied on the guides of any

mobile components;

z Keep excessive parts of power cables for those mobile components, such as

grounding cable of doors, to free the cables from possible stress. When installing

these components, make sure the excessive cables will not touch heat source,

sharp point, or keen edges. Use high temperature cables near the heat sources;

4-16

Figure 4-20 Cable fixing example

z Fix the terminal of harder power cables to free the terminal and the cable from

stress;

z No tapping screw can be used to fasten the cabling terminals;

z The power cables of the same type and in the same direction should be bound

together and kept clean and straight;

Follow the parameters defined in the following table for binding cables with ties.

Table 4-4 Tie-binding parameters

Cable bundle diameter (mm) Space between bundles (mm)

10 80~150

10~30 150~200

30 200~300

z No cable or bundle can tie a knot;

z The metal parts of crimping cold-pressed terminal blocks (such as air switch)

cannot stretch beyond the blocks.
