Chapter 2 Preparation

Chapter 2 Preparation 2.1 Safety Precautions To avoid any device impairment and bodily injury caused by improper use, observe these rules: z

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

z

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

z

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

z

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

z

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

z

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

z

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

2.2 Installation Site The S3900 series must be used indoors. You can mount your switch in a cabinet or on a desk, but make sure: z

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

z

The cabinet or desk has a good ventilation system.

z

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

z

The cabinet or desk 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

Chapter 2 Preparation

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 1.11 “Features of the S3900 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 Table 2-1: Table 2-1 Dust content limits in an equipment room Substance

Unit

Content ≤ 3 × 10

Dust

(No visible dust on the tabletop for three days)

Remark: the diameter of a dust particle ≥ 5 μm

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 Table 2-2. Table 2-2 Harmful gas limits in the equipment room Maximum (mg/m3)

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:

Huawei Technologies Proprietary 2-2

Installation Manual Quidway S3900 Series Ethernet Switches z

Chapter 2 Preparation

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

z

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

z

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

z

Route interface cables only indoors to prevent signal ports from getting damaged by over-voltage or over-current caused by lightning strikes.

2.2.4 Laser Safety The S3900 series are class-1 laser devices. If the extended optical boards 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.

Caution: Staring into the laser beam produced by the fiber can hurt your eyes.

Caution: z

Before powering on the switch, connect the ground wire.

z

The length of the DC power cord must be less than 3 m (9.8 ft.).

z

Only the PoE power supply recommended by Huawei can be used for the S3928P-PWR-SI, S3928P-PWR-EI, and S3952P-PWR-EI. The –48 VDC from the equipment room cannot be used directly. Otherwise, devices may be damaged.

3.2.3 Connecting the Ground Wire

Caution: Correctly connecting the switch ground wire is crucial to the lightning protection and electromagnetic susceptibility (EMS) of a switch.

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: z

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.)

Chapter 5 Loading Boot ROM and Host Software

Chapter 5 Loading Boot ROM and Host Software Switch software loading through serial ports in the past is time consuming and cannot be operated remotely. To address these problems, TFTP and FTP are used to allow software and file downloading through Ethernet ports. The following subsections describe how to load software and files in these two approaches.

5.1 Introduction to Loading Approaches To load software remotely, use FTP or TFTP. To load software at the local, use XModem at the Console port or TFTP/FTP at an Ethernet port.

Note: Ensure that the Boot ROM and host software versions that you download can work with each other.

5.2 File attribute in Boot ROM 5.2.1 Introduction to File Attribute In Boot ROM, application files, configuration files, and Web files support three kinds of attributes: main, backup, and none, which are described in Table 5-1. Table 5-1 File Attribute Attribute

Usage

Feature

main

Indicates the main boot file, which is used by a device to boot.

Only one application file, one configuration file, and one Web file in the Flash can have the main attribute.

(*)

backup

Indicates a boot file with the backup attribute. When a device cannot boot with the main boot file, it will use the backup boot file to boot.

Only one application file, one configuration file, and one Web file in the Flash can have the backup attribute.

(b)

Huawei Technologies Proprietary 5-1

Installation Manual Quidway S3900 Series Ethernet Switches

Attribute

none

Chapter 5 Loading Boot ROM and Host Software

Usage

Feature

Indicates a file having neither the main attribute nor the backup attribute.

—

Identification No special identification

Note: z

The suffixes of application, configuration, and Web files are app, cfg, and web respectively.

z

A file can have both the main attribute and the backup attribute. Such a file is displayed with identification of (*b).

If you specify a file to have the main attribute when there is already a main boot file, the original main boot file will lose the main attribute, ensuring that only one application file, one configuration file, and one web file in the Flash have the main attribute. The same is true for the backup attribute. Operations of a file are separate from those of the attributes. For example, when you delete a main boot file from the Flash, the main attribute of the file remains. If you download a valid file with the same name to the Flash, the new file will have the main attribute. The file attribute feature is backward compatible. When you upgrade the Boot ROM of a device, the original default app boot file has the main attribute.

5.2.2 Impact of File Attributes on Downloading and Booting I. Downloading When you download an application, configuration, or Web file from the boot menu through TFTP or FTP, the device identifies the file by its suffix and checks the validity of the file if it is an app file. Then, the device displays a message for you to confirm if you want to set it as a boot file. You can set file attributes at prompt.

Note: If a downloaded file has the same name as that of an existing file in the Flash, the new file will overwrite the original one, while having the same attributes.

Huawei Technologies Proprietary 5-2

Installation Manual Quidway S3900 Series Ethernet Switches

Chapter 5 Loading Boot ROM and Host Software

II. Booting When a device boots, it first uses the application file with the main attribute. If the boot operation fails, the device selects the application file with the backup attribute to try again. If the boot operation fails again, the device displays an error message and repeats the above procedure.

Note: z

If the device boots failed with an application file with main attribute, it will display an alert message.

z

If the specified application file does not exist, the switch will automatically choose an existing valid application file to boot.

5.2.3 Setting the Attribute of a File You can set the attribute of a file from the Boot menu. The following takes an application file for example to describe the required steps:

I. Enter the Boot menu and input 2 to select “2. Select application file to boot” and enter the corresponding submenu. 1. Download application file to flash 2. Select application file to boot 3. Display all files in flash 4. Delete file from flash 5. Modify bootrom password 6. Enter bootrom upgrade menu 7. Skip current configuration file 8. Set bootrom password recovery 9. Set switch startup mode 0. Reboot Enter your choice(0-9):2 Select application file to boot 1. set application files 2. set configuration files 3. set web files 0. return Enter your choice(0-3):1

II. Set the attributes of application, configuration, or Web files as needed. In this example, enter 1 to select “1. set application files”.

If a file has neither the main attribute nor the backup attribute after you change the attributes of other files, the device will give the file the attribute of none and display an alert message.

IV. If you change the attribute of an application file to main, the device will display a message for you to confirm whether you want to boot the device immediately. Do you want to run s3900-2.app now? Yes or No(Y/N) y

If you enter y, the device will reboot immediately. If you enter n, the device will return to the [Select application file to boot] submenu.

5.3.2 Loading Software from Console Port Using XModem I. Introduction to XModem XModem is a file transfer protocol widely used for its simplicity and good performance. XModem transfers files through the Console port, supporting data packets of 128 bytes and 1 KB. With respect to reliability, it supports checksum, CRC, and the error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is ten. XModem transfer is completed by receiving and sending programs together. Receiving program initiates packet checking method negotiation by sending the negotiation character. If negotiation passes, the sending program starts packet transfer. Upon 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 receipt of the acknowledgement, the sending program continues to send the next packet; upon receipt of the reject, it retransmits the packet.

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.

Appendix A Lightning Protection of the Switch

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.
