15 Chapter 3 Installation Preparation Chapter 3 Installation Preparation 3.1 Safety Information To avoid damage to human body and devices, please read the following safety recommendations carefully before installing S7500 Series Ethernet Switches. The recommendations do not cover every possible hazardous condition General Safety Recommendations Turn OFF all the powers and remove all the power cords before opening the chassis. Keep the chassis clean and dust-free. Keep the chassis and installation tools away from walk areas. Do not wear loose clothing, jewelry (including ring and necklace, and so on) or any other things that could get caught in the chassis when you install and maintain the switch Safety of Electricity Look carefully for possible hazards in your work area, such as ungrounded power extension cables, missing safety grounds, and moist floors. Locate the emergency power-off switch in the room before installation. Shut the power off at once in case accident occurs. Unplug all the power cords and external cables before moving the chassis. Better not maintain the equipment alone when it has been powered by electricity. Never assume that power is disconnected from a circuit. Always check. Do not place the switch on a moist area and avoid liquid flowing into the switch Safety of Moving S7500 Series Switches are rather big and heavy, so follow the recommendations below when moving them. Turn off all the powers and remove all the power cords before opening the chassis. Do not move the switch alone. Work with another person. Move the switch slowly and stably. Never move suddenly or twist your body. Move the switch at stable and consistent paces with your peer. Keep balance of your body. 3-1

16 Chapter 3 Installation Preparation Caution: Hold the handle at the back of the chassis, instead of holding the power handlers or putting fingers into the vent of chassis when moving the switch. Since the power handler and vent have not been designed to bear the weight of the entire chassis, it may hurt the switch or even your body when you carry the switch Wearing an ESD Wrist Strap To prevent the electric component from being damaged by the electrostatic discharge (ESD), take ESD measures for the area where the switch is located and note the points below: Always wear an ESD wrist strap when installing the parts, especially the electric printed circuit boards, of the switch. 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 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 wrist strap hole in the switch chassis or attach the alligator clips to the grounding screw of the chassis. Step 4: Make sure the ESD wrist strap is well grounded. Note: The ESD wrist strap is shipped with the S7500 Series Ethernet Switches. There is an ESD wrist strap hole above the SRPU slot of the S7500 Series Switch chassis. The grounding screw is located on the power distribution box sit on the back floor of the chassis. Caution: For safety case, check the resistance of the ESD wrist strap. The resistance between human body and the ground should be 1 to 10M ohm. 3-2

17 Chapter 3 Installation Preparation Safety of Laser Some LPUs of S7500 Series Ethernet Switches have optical interfaces. In operating status, it is prohibited to stare into the open optical interface because the laser being transmitted through the optical fiber will produces a small beam of light, it has very high power density and is invisible to human eyes, when a beam of light enters the eye, retina may be burned. Caution: Staring at the laser beam inside the fiber could hurt your eyes. 3.2 Examining Installation Site S7500 Series Ethernet Switches can only be used indoors. To ensure that the switch works normally and expand its service life, the installation environment shall meet the requirements below 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 for a long time, it will lead to bad insulation of the insulating material or even creepage. Sometimes, the mechanical performance changes of material, the rustiness and corrosion of some metal parts are also likely to occur. 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 Cleanness Requirements Dust is a big harm for the normal operation of the switch. The indoor dust accumulated on the chassis can cause electrostatic adsorption, resulting in the poor contact of the connector or metal contact point. 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 failure. The required specifications on dust content and particle diameter in an equipment room are shown in the following table. 3-3

18 Chapter 3 Installation Preparation Table 3-1 Required specifications on dust content in an equipment room Mechanical active material Unit Content Dust particle particle/m³ 3 x 10 4 (No visible dust on desk in 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 2, H 2 S, NO 2, NH 3 and Cl 2, the value limits of which are shown in the following table: Table 3-2 Value limits on harmful gas contents in an equipment room Gas Maximum (mg/m 3 ) SO H 2 S 0.06 NH Cl 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: Adopt effective measures to protect the power supply system against the power grid interference. 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. Keep the switch far away from the radio launcher, radar launcher, and high-frequency devices working in high currents. If necessary, adopt electromagnetic shield 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 user should provide good grounding system for the switch. 3-4

II. Connecting Category-5 Cables Step 1: Plug one end of the network cable into the Ethernet RJ-45 jack of the switch to be connected. Step 2: Plug the other end of the cable into the RJ-45 port of the peer device Connecting Fiber I. Introduction to Fiber Connector Before connecting the fibers, make sure the type of the connector and the fiber are consistent with that of the optical interface. 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. MT-RJ fiber connector: It integrates two channels of light sources into a single fiber, which actually reduces the ports of a connector. 4-15

37 Chapter 4 Switch Installation Figure 4-16 MT-RJ connector SC fiber connector Figure 4-17 SC connector LC fiber connector Figure 4-18 LC connector II. Connecting Fiber Step 1: Remove the protective cap of the fiber and clean the Step 2: Remove the protective cap from the optical interface of the switch, and plug one end of the fiber into this interface. Step 3: Connect the other end of the fiber connector to the corresponding device. Caution: When the optical interface has not been connected with a fiber connector or its dustproof cover is open, there might be some invisible radiation emitted from the optical interface. So do not stare into the optical interface directly. Cover the optical interface if there is no connector plugged in. 4-16

38 Chapter 4 Switch Installation 4.10 Recommendation on Installation Cabling Bench-Mounted Switch For only selling an integrated chassis, you do not have to care about the cabling inside or outside the cabinet. All the interface service cables run on the left side of the chassis (cabling channel), and the chassis power cords (including AC and DC power cords) run by the rear chassis panel Rack-Mounted Switch For the switches mounted in a 19-inch standard rack or B68-22 cabinet, the service cables are bound on the cable binding rack at the left side of the chassis and 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 cords run out of the rear left of the chassis and either on the cable rack or in the raised floor as near as possible according to the situation in an exchange equipment room (concerning DC power distribution cabinet, lightning protection box, terminal strip and so on) Cable Binding for Installation Correctly Use the Labels Correctly edit the label and paste it to the right place of the bound cables. For details, refer to the description of label usage in the appendix Precautions for Binding Cables Bind the cables straight in the cabinet. No twisting or bending. 4-17

39 Chapter 4 Switch Installation Twisting Bending Figure 4-19 Cable binding example I The cable body cannot be bent beyond twice of its diameter. The cable running out of a connector cannot be bent beyond five times of its diameter. Different cables (power cord, signal cable, ground wire, and so on.) 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 cord and signal cable should be no less than 30 mm; The cable binding rack and cable channel inside and outside a cabinet should be smooth and stretch no sharp points. The metal hole through which a cable runs through should have a smooth and fully surface or an insulating bush; Use the right type of ties to bind the cables. Do not bind any cables with tied ties. H3C technologies provides the following types of ties: 100 x 2.5 mm (3.9 x 0.01 in), 150 x 3.6 mm (5.9 x 0.1 in), 300 x 3.6 mm (11.8 x 0.1 in), 530 x 9 mm (20.9 x 0.4 in), and 580 x 13 mm (22.8 x 0.5 in); Bind the cables with ties and cut the extra parts. Trim the cut and leave no sharp points. See the following figure: 4-18

40 Chapter 4 Switch Installation Figure 4-20 Cable binding example II 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 4-21 Cable binding example III 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. 220V power cord and -48V power cord cannot be tied on the guides of any mobile components; Keep excessive parts of power cords for those mobile components, such as ground wire 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; 4-19

41 Chapter 4 Switch Installation For the cable terminals fixed with screw thread, the screws or nuts should be fastened and prevented from loosing. See the following figure; Flat Flat washer washer Spring washer Nut Figure 4-22 Cable fixing example Fix the terminal of harder power cords to free the terminal and the cable from stress; No tapping screw can be used to fasten the cabling terminals; The power cords 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 4-7 Tie-binding parameters Cable bundle diameter (mm, in) Space between bundles (mm, in) 10, to150, 3.1 to to 30, 0.4 to to 200, 5.9 to , to 300, 7.9 to 11.8 No cable or bundle can tie a knot; The metal parts of crimping cold-pressed terminal blocks (such as air switch) cannot stretch beyond the blocks. 4-20

42 Chapter 4 Switch Installation 4.12 Check after Installation Caution: Confirm that you have turned off the power before checking, otherwise, improper connection will hurt people or the component of the switch. After installing the switch, please check if the items listed in the following table are normal.

Loading software from Console port using XModem Introduction to XModem XModem is a file transfer protocol widely used due to its simplicity and good functions. XModem transfers files via Console port, supporting data packets of 128 bytes and 1KB. With respect to reliability, it supports checksum, CRC, and error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is ten. XModem transmission is completed by receiving program and sending program. Receiving program initiates packet checking method negotiation by sending the negotiation character. If the negotiation passes, sending program starts packet transmission. Upon the receipt of a complete packet, the receiving program checks it using the agreed-upon check method. If the check succeeds, the receiving program sends an acknowledgement character; if the check fails, it sends a reject character. Upon the receipt of the acknowledgement, the sending program continues to send the next packet; upon the receipt of the reject, it retransmits the packet.
