There are two port status LEDs on both sides (yellow LED on the left and green LED on the right) of each 10/100BASE-TX Ethernet port of S3100 series. They indicate the active, link, duplex, and speed statuses of the port.

In addition, there are an A/L LED and a D/S LED on each model of S3100 series. These two LEDs indicate the mode of the port status LEDs. When the A/L LED is on, the port status LEDs respectively indicate the active status and link status of ports. When the D/S LED is on, the port status LEDs respectively indicate the duplex status and speed status of ports. Either the A/L LED or the D/S LED is on at a specific time. For details, see Table 1-3.

Table 1-3 Description of port status LEDs on S3100 series

Port status mode LED	Port status LED		Description
The A/L LED is on	Yellow LED (left)	BLINKING	The port is in the active state and there is traffic on the port.

Chapter 2  Installation Preparation

2.1  Precautions

To avoid any device impairment and body injury resulting from improper use, please take the following precautions:

l           Before cleaning the switch, disconnect the power. Do not clean the switch with wet cloth or liquid.

l           Keep the switch away from water or dampness. Prevent water or moisture from entering the switch chassis.

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

l           Keep the switch room drafty and the switch ventilation hole free of obstruction.

l           The switch can operate normally only under correct voltage input. Make sure that the operating voltage is consistent with that labeled on the switch.

l           To prevent electric shock, do not open the chassis while the switch is operating, and do not open the chassis arbitrarily even when the switch is powered off.

l           Before changing interface cards, wear an ESD-preventive wrist strap to prevent the cards from being damaged by electrostatic discharge.

2.2  Requirements on Environment

S3100 Series Ethernet Switches must be used indoors. When you install your switch in a cabinet or on a desk, you must ensure:

l           Enough space is reserved near the air-intake hole and the ventilation hole of the switch for heat dissipation of the switch chassis.

l           The cabinet or the workbench takes good ventilation and heat dissipation system.

l           The cabinet or the desk is solid enough to bear the weight of the switch and the accessories.

l           The cabinet or the desk is 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

You should keep your equipment room within the proper temperature and humidity ranges to ensure the normal operation and working life of your switch. If the humidity in the equipment room is too high for a long time, it may decrease the insulation attribute of insulating material or even cause electric leakage of insulating material, and, sometimes, may change the mechanical performance of material and cause the rustiness and corrosion of metal parts. If the relative humidity is too low, the captive screws may become loose due to the shrinking of insulation washers; in addition, electrostatic is more likely to be produced in a dry environment, which may damage the circuit of the switch. High temperature may cause even greater damage to the switch. High temperature for a long time will speed up the aging of insulation material, greatly lower the reliability of the switch and greatly reduce the life span of the switch.

For the temperature and humidity requirements of different models, refer to section 1.4  “Technical Specifications”.

2.2.2  Cleanness Requirements

Dust is a potential hazard to the safe operation of the switch. 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 indoor relative humidity is low; in this case, it may not only shorten the device’s working life, but also incur communication failure. 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 the equipment room

Physical active substance	Unit	Content
Dust particle	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 content of chloride, acid, and sulfide in the air of the equipment room. These kinds of harmful gas will accelerate metal corrosion and aging of certain parts. The equipment room should be protected from the intrusion of harmful gases such as SO₂, H₂S, NH₃ and Cl₂. The limits of these kinds of harmful gas are shown in the following table.

Table 2-2 Limits on harmful gas in the equipment room

Gas	Max content (mg/m³)
SO2	0.2
H2S	0.006
NH3	0.05
Cl2	0.01

 

2.2.3  Anti-interference Requirements

A switch in use may be affected by the interference from outside the system by way of capacitance coupling, inductance coupling, electromagnetic radiation, public impedance (including the grounding system) coupling or conducting line (power line, signaling line, and transmission line). Therefore, you should pay attention to the following:

l           If AC supply system is TN system, AC power socket should be a single-phase three-line power socket with Protection Earth (PE) so that the filter circuit on the equipment can effectively filter out the interference coming from the power supply system.

l           Keep the switch far away from high-power radio transmitters, radars, and high-frequency heavy-current devices.

l           Adopt electromagnetic shielding measure if necessary. For example, you can adopt shielded interface cable.

l           Wire interface cables indoors. Do not wire cables outdoors in case that over-voltage and over-current damage the device.

2.2.4  Laser Usage Security

S3100 Series Ethernet Switches are category-1 laser equipment.

 

 

2.3  Installation Tools

l           Phillips screwdriver

l           Flat-blade screwdriver

l           ESD-preventive wrist strap

I. AC power socket (recommended)

You are recommended to use a mono-phase three-core power socket with a neutral point or a multi-function power socket for computers. The neutral point of the power in your building must be well grounded. Normally, the neutral point of the power supply system in your building has already been grounded during the construction and wiring; but you should make sure this is the fact.

Figure 3-13 Recommended AC power socket

II. Connecting AC power cable

1)         Connect one end of the grounding cable (delivered with the switch) to the grounding screw on the rear of the chassis and the other end to the ground nearby.

2)         Connect one end of the power cable to the power socket on the rear panel of the chassis and the other end to an outside AC power socket.

3)         Check whether the PWR LED on the front panel of the switch is ON. If yes, the power is properly connected.

2)         Check whether the PWR LED on the front panel of the switch is ON. If yes, the power is properly connected.

 

 

3.2.3  Connecting Grounding Cable

 

 

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 (commonly known as PGND). This chassis ground must be securely connected to the earth so that the faradism and leakage electricity can be safely released to the earth, enhancing the EMS capability of the switch.

Ground the switch as follows:

l           When a grounding strip is available at the installation site, attach one end of the yellow-green grounding cable 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 your building are not suitable for grounding the switch. The grounding cable of the switch should be connected to the construction engineering ground of the equipment room.)

(1) Power input	(2) Grounding screw
(3) Protection grounding cable	(4) Grounding strip

Figure 3-17 Ground the switch through a grounding strip

l           When there is no grounding strip but there is cement floor nearby where a grounding body is allowed to be buried, hammer an angle steel/steel pipe no shorter than 0.5 m (19.7 in.) into the earth, with the yellow-green grounding cable of the switch welded onto the angle steel/steel pipe and the jointing point being processed against erosion.

Chapter 5  Boot ROM and Host Software Loading

Traditionally, the loading of switch software is accomplished through the serial port. This approach is slow, inconvenient, and cannot be used for remote real-time loading. To resolve these problems, the TFTP and FTP modules are introduced into the switch. With these modules, the software and files can be loaded through Ethernet port conveniently.

This chapter introduces how to load Boot ROM and host software into a switch locally and how to do this remotely.

5.1  Introduction to Loading Approaches

You can load the software locally by using:

l           XModem via console port

l           TFTP via Ethernet port

l           FTP via Ethernet port

You can load the software remotely by using:

l           FTP

l           TFTP

 

 

5.2  Local Software Loading

If your terminal is directly connected to the switch, you can load Boot ROM and host software locally.

Before loading the software, make sure that your terminal is correctly connected to the switch to ensure the successful loading.

5.2.2  Loading Software Using XModem Through Console Port

I. Introduction to XModem

XModem is a file transfer protocol that is widely used due to its simplicity and good performance. XModem transfers files via console port. It supports two types of data packets (128 bytes and 1 KB), two check methods (checksum and CRC), and error packet retransmission mechanism (generally the maximum number of retransmission attempts is ten).

The XModem transmission procedure is completed by the cooperation of a receiving program and a sending program: The receiving program sends a negotiation packet to negotiate a packet check method. After the negotiation, the sending program starts to transmit data packets. When receiving a complete packet, the receiving program checks the packet using the agreed method. If the check succeeds, the receiving program sends an acknowledgement packet and the sending program proceeds to send another packet; otherwise, the receiving program sends a negative acknowledgement packet and the sending program retransmits the packet.

Step 4: Restart the switch.

<H3C> reboot

 

 

After the above operations, the Boot ROM and host software loading is completed.

Pay attention to the following:

l           Host software loading takes effect only after you restart the switch with the reboot command.

l           If the space of the flash memory is not enough, you can delete the useless files in the flash memory before software downloading.

l           No power-breaking is permitted during software loading.

5.3.2  Remote Loading Using TFTP

The remote loading by using TFTP is similar to the remote loading by using FTP. The only difference is that it is TFTP that you use when loading software to the switch. In this case, the switch can only be used as a TFTP client.

 

Chapter 6  Maintenance and Troubleshooting

6.1  Software Loading Failure

If software loading fails, the system keeps running in original version.

In this case, check if the physical ports are properly connected:

l           If not, reconnect them correctly and restart the loading procedure.

l           If so, check the loading procedure information displayed on the HyperTerminal for input errors. If there is any input error, restart the loading procedure with correct input. For example:

1)         When using XModem, verify that you have reset the bits per second of the HyperTerminal to 9600 bps after loading the software with a bits per second other than 9600 bps;

2)         When using TFTP, verify that you have provided:

l           Correct server and switch IP addresses,

l           Correct name of the software to be loaded,

l           Correct working path of TFTP server;

3)         When using FTP, verify that you have provided:

l           Correct server and switch IP addresses,

l           Correct name of the software to be loaded,

l           Correct username and password.

If software loading fails but there are neither physical connection problems nor input errors, please contact your agent for help.

6.3  Power System Failure

You can check whether the power system of the switch fails by viewing the POWER indicator on the front panel. If it is in normal operation, the POWER indicator should stay on. Otherwise, please check that:

l           The switch power cable is correctly connected.

l           The power input to the switch matches the requirement as labeled on the switch.

6.4  Configuration System Failure

After the switch is powered on and the system is normal, the booting information will be displayed on the configuration terminal. If the configuration system has any faults, there will not be any screen display at the configuration terminal or the displayed characters will be totally illegible.

I. Troubleshooting when there is no terminal display

If there is no output information after the configuration is powered on, please check that:

l           The power supply is normal

l           The console cable is properly connected

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. Troubleshooting when the terminal display is illegible

If there is illegible display at the configuration terminal, the cause might lie in the parameter setting error at the terminal (such as HyperTerminal). Please confirm the following terminal parameter (such as HyperTerminal) settings:

l           Bits per second: 9600

l           Data bits: 8

l           Parity check: None

l           Stop bits: 1

l           Flow control: None

l           Terminal emulation: VT100.
