Chapter 2 Installation Preparation

Chapter 2 Installation Preparation 2.1 Precautions To avoid any device impairment and bodily injury because of improper use, please follow the precautions listed below: Before cleaning the switch, please unplug the switch connector first. Do not clean the switch with wet cloth or with liquid. Do not place the switch near water or any damp area. Prevent water or moisture from entering the switch chassis. Do not place the switch on the unstable cases or desks, as the switch might be damaged severely in case of a fall. Ensure proper ventilation of the room and keep the switch ventilation hole free of obstruction. The switch can operate normally under correct voltage input. Make sure that the operating voltage is consistent with that labeled on the switch. Do not open the chassis while the switch is in operation to protect the safe of the operator and the switch. Before changing I/O board, wear ESD-protective gloves for fear of damaging the board with ESD.

2.2 Requirements on Environment S3552F must be used indoors. The following conditions must be met regardless of whether you install the switch in a 19-inch standard cabinet or install it directly on table-top. Make sure that enough room is left for the air-intake hole and the ventilation hole of the switch, so that the heat dissipation of the switch chassis can be guaranteed. Make sure that the ventilation and heat dissipation systems of the cabinet and the table-top are good. Make sure that the cabinet and the table-top are stable enough to bear the weight of the switch and the accessories. Make sure that the cabinet and the table-top are 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 To ensure the normal operation and service life of a switch, the user needs to maintain the temperature and the humidity of the equipment room at a certain level. If the

2-1

Installation Manual Quidway S3552F Ethernet Switch

Chapter 2 Installation Preparation

humidity level in the equipment room is too high for a long time, it will lead to bad insulation of the insulating material or even leakage. 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 shrinking of insulation washers. Meanwhile, electrostatic phenomena are likely to happen in the dry weather environment, which will jeopardize the CMOS circuit of the switch. The higher the temperature, the greater the damage to the switch will be. 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 life span seriously.

2.2.2 Cleanness Requirements Dust will hazard safe operation of the equipment. 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 relative indoor humidity is low, which will not only shorten the device’s service life, but also incur communication failures. 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 an equipment room Mechanical active material Dust particle

Unit

Content

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 air content of salts, acids, and sulfides in an equipment room. These harmful gases will accelerate metal corrosion and aging process of certain parts. The equipment room should be protected from harmful gases such as SO2, H2S, NH3 and Cl2, the value limits of which are shown in the following Table. Table 2-2 Value limits on harmful gas contents in an equipment room Max. (mg/m3)

Chapter 2 Installation Preparation

2.2.3 Anti-interference Requirements A switch in use may be affected by the interference sources outside the system in a way of capacitance coupling, inductance coupling, radiation of electromagnetic wave, public impedance coupling (including the grounding system) or conducting line (power cord, signaling line and transmission line, etc.). Therefore, the following should be considered: If AC supply system is TN system, AC power socket should be a monophase three-wire power socket with Protection Earth (PE). Thereby, the filter circuit in the equipment can effectively filter interference from the power supply system. Keep the switch far away from radio launcher, radar launcher, and high-frequency devices working in high current. Adopt the measure of electromagnetic shielding if necessary. For example, you can adopt shielded interface cable. Interface cable must be run indoors, and outdoor cabling is not permitted, otherwise, over-voltage and over-current may damage the device.

2.2.4 Laser Usage Security S3552F belongs to class-1 laser devices. In operating status, it is prohibited to stare into the open optical interface because the laser being transmitted through the optical fiber will produce a small beam of light, because it has very high power density, 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.

2.3 Installation Tools Flat-blade screwdriver Phillips screwdriver ESD-preventive wrist strap

Caution: The installation tools are not shipped with S3552F, so you have to prepare them beforehand.

Chapter 3 Installation

Caution: On the mounting screw of the chassis of any Quidway series switches, there is a seal which must be kept intact before the sales agent performs maintenance on the switch. The user should contact local agent for permission if it is necessary to open the chassis. Otherwise, he/she will bear the responsibility for possible damages.

3.1 Installing a Switch 3.1.1 Installing the Switch on a 19-Inch Rack A switch can be mounted in a 19-inch standard rack. The mounting procedure is described below: Step 1: Check the grounding and stability of the cabinet. Fix the mounting ears at both sides of the front panel of the switch with screws. Step 2: Place the switch on a shelf in the cabinet. Depending on the actual situation, slide the switch along the guides of the cabinet to an appropriate position. Step 3: Use screws to fix the mounting ears on the fixing guides at both sides of the cabinet. Make sure that the switch is securely fixed in the cabinet by the brackets on each slot and the mounting ears.

Figure 3-1 Switch mounting (on a 19-inch rack)

Installation Manual Quidway S3552F Ethernet Switch

Chapter 3 Installation

Note: The mounting ears are used for fixing rather than bearing. When the switch is mounted on a 19-inch standard rack, it should be borne by slide rails (fixed on the rack).

3.1.2 Free-Standing the Switch on a Tabletop If there is no 19-inch standard rack, you may have to place the switch on clean table-top, which is a relatively easy way to operate. The user needs only pay attention to the following during such operation: Make sure that the table is stable and well grounded. Leave about 10 centimeters of space around the switch for heat dissipation. Do not place heavy objects on the top of the switch.

3.2 Connection of Power Cord and Ground Wire 3.2.1 Connecting AC Power Cord I. AC power socket (Recommended) A monophase three-wire power socket with a neutral point connector, or a multi-functional power socket for the computer is recommended. The neutral point of the power in a building must be well grounded. Normally, the neutral point of the power supply system in a building is buried in the ground during the construction and wiring. The user must make sure that the power supply for the building is grounded. Neutral point

Installation Manual Quidway S3552F Ethernet Switch

Chapter 3 Installation

Caution: The correct connection of the switch ground wire is the primary guarantee for the lightning protection and anti-interference; so the user must connect the ground wire correctly.

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 (also called PE). This chassis must be well grounded so that the faradism and leakage electricity can be safely released to the ground to enhance the switch capability of withstanding electromagnetic interference. The switch should be grounded in the following way. If there is grounding strip in the Ethernet switch installation environment, attach one end of the yellow-and-green protection ground wire to the grounding screw of the grounding strip and fasten the captive nuts. Note that the fire main and lightning rod of a building are not suitable for grounding the switch. The ground wire of a switch shall be connected to the grounding device of the equipment room.

5.2.2 Loading Software from Console Port Using XModem I. 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.

Chapter 6 Maintenance and Troubleshooting 6.1 Dealing with Load Failure If loading fails, the original version will remain in the system. In this case, check that the physical ports are correctly and well connected. If they are not, reconnect them correctly and restart loading procedures. If there are no problems with the physical connections, please carefully check information about the loading procedures for input errors on the HyperTerminal. 1)

When using XModem, check that you have reset the baud rate of the HyperTerminal to 9600bps after loading the software with a baud rate other than 9600 bps;

2)

When using TFTP, check that you have provided: Correct server and switch IP addresses; Correct name of the software to be loaded; Correct path for TFTP Server to operate on program files.

3)

When using FTP, check that you have provided: Correct server and switch IP addresses; Correct name of the software to be loaded; Correct username and password.

If loading fails when there are neither physical connection problems nor input errors, please contact the local agents of Huawei Technologies Co., Ltd. for help.

6.2 Password Loss If the Boot ROM password of the switch is lost, please contact the local agent.

6.3 Power System Failure You can check whether the power system of the switch fails by viewing the power LED on the front panel. If it is normal, the power LED should stay ON. Otherwise, please check whether The switch power cord is correctly connected. The power input to the switch matches the requirement for the switch.

faults, there will be no screen display at the configuration terminal or the displayed characters will be totally illegible.

I. Nothing being displayed on the terminal If there is no output information after the configuration terminal is powered on, please check whether The power supply is normal. The Console cable is connected correctly. If no problems are found after the above-mentioned items have been checked, the cause may lie in the Console cable or the settings of the terminal (such as HyperTerminal) parameters. Please perform the corresponding check.

II. Displaying illegible characters on the terminal If there is illegible display at the configuration terminal, the cause might lie in parameter setting errors at the terminal (such as HyperTerminal). Please confirm parameter (such as HyperTerminal) settings for the terminal: baud rate should be set to 9600, data bit to 8, parity to none, stop bit to 1 and flow control to none, and select VT100 as terminal emulation.

Appendix A Lightning Protection of the Switch

Appendix A Lightning Protection of the Switch A.1 Installation of Lightning Arrester for AC Power (Socket Strip with Lightning Protection)

Caution: Lightning arrester will not be shipped with the switch. You should purchase it by yourself if needed.

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. Grounding and polarity indicator (red) : On means that the lines are wrongly connected (either the ground wire is not well connected, or the live and zero lines are wrongly connected). Please check the power supply circuit. Power switch Normal operation indicator (green): On means that the arrester works normally. Otherwise, it means that the protection circuit has been damaged. Power socket (complied with IEC standard), connected to the power supply of the equipment room through power cord Mainboard

Caution: z

Make sure that the arrester is well grounded before using the lightning arrester for power.

z

After inserting AC power cord plug of switch into the socket of lightning arrester, if the green LED is on and the red LED does not alarm, it means that the lightning arrester of power is running and the function of lightning protection has taken effect.

z

Pay adequate attention if the red LED is on. You should correctly locate the problem, whether it is caused because the ground wire of the arrester is not well grounded or because the live and zero wires are connected in reverse direction. You may check that in the following way. When the red LED is on, use a multimeter to examine polarity at the power socket of the arrester. If it is same to that of the power socket in the equipment room, it means that arrester is not well grounded. If it is adverse to that of the power socket in the equipment room, it means that the power socket of the arrester is set to the reverse polarity. In this case, you should open the power socket of arrester to correct polarity. After that, if the red LED still alarms, it means that the arrester is not well grounded yet.

A.2 Installation of Lightning Arrester for Network Port

Note: Lightning arrester for network port is specially designed for the Ethernet port of 10/100M electrical interface (RJ-45 connector is adopted in this case).

Caution: Lightning arrester for network port will not be provided along with the switch, and you should purchase it by yourself if needed.

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.

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.

Note: The instruction of lightning arrester for network port contains the technical specifications, installation and maintenance guide of the arrester. Please carefully read it before installing the arrester.

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: z

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.

z

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.

z

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.
