Product overview

Introduction

H3C S5120-SI Switch Series is a line of Layer 2 Gigabit Ethernet switching products developed by Hangzhou H3C Technologies Co., Ltd. (hereinafter referred to as H3C). The S5120-SI switches are intelligent manageable switches designed for network environments where high performance, high-density port distribution, and easy installation are required.

With 10/100/1000 Mbps Ethernet interfaces, the S5120-SI switches are mainly deployed at the access layer in enterprise networks requiring Gigabit to the Desktop (GTTD) application and at the distribution layer in metropolitan-area networks (MANs). In the latter deployment, the S5120-SI Switch Series provides GE el ect rical inte rfac es fo r use r acc ess o r low-end switch convergence in the downlink direction. In the uplink direction, they are aggregated to large-capacity Layer 3 switches or switches at the exchange office through their GE interfaces.

Table 1 and Table 2 show the models and system specifications of the S5120-SI Switch Series.

Preparing for installation

Safety precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

• Before cleaning the switch, unplug the power cord of the switch first. Do not clean the switch with

wet cloth or liquid.

• Do not place the switch near water or in a damp environment. Prevent water or moisture from

entering the switch chassis.

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

of a fall.

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

obstruction.

• Connect the yellow-green protection grounding cable before power-on.

• Make sure that the operating voltage is as required.

• Do not open the chassis to avoid electrical shocks when the switch is operating or just when the

switch is powered off.

Examining the installation site

The S512 0-SI Switch Series must be used indoors. You can mount the switch in a rack or on a work bench, but make sure:

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

• The rack or workbench has a good ventilation system.

• The rack is sturdy enough to support the switch and its accessories.

• The rack or workbench is well grounded.

To ensure normal operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.

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 metal corrosion. However, if the relative humidity is too 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 circuits on the device. A high temperature is the most undesirable condition, because it accelerates the aging of insulation materials and thus significantly lowers reliability and service life of the switch.

For the temperature and humidity requirements of different models, see overview”.

Table 1 in the chapter “Product

Page 24

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. Especially when the indoor relative humidity is low, electrostatic adsorption is more likely to happen. This can not only shorten the service life of your device but also cause communications failures. The following table lists the dust concentration limit.

Table 12 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m

Dust

Note: The dust diameter is greater than or equal to 5 m.

 3 x 104 (no visible dust on the tabletop over three days)

Besides dust, there are rigorous limits on the content of harmful substances in the air that can accelerate the corrosion and aging of metals, such as chloride, acid, and sulfide in the equipment room. The equipment room must be protected against ingression of harmful gases such as SO For specific requirements, see the following table.

Table 13 Harmful gas limits in the equipment room

Gas Maximum concentration (mg/m

H2S 0.006

NH3 0.05

Cl2 0.01

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, pay attention to the following:

0.2

)

, H2S, NH3, and Cl2.

)

• The AC power system is a TN system, so use a single-phase three-wire power socket with a

protection earth (PE) to effectively filter interference from the power grid.

• Keep the switch far away from radio transmitting stations, radar stations, and high-frequency

devices.

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

• Route interface cables only indoors to prevent signal ports from getting damaged by over-voltage

or over-current caused by lightning strikes.

Laser safety

The S5120-SI Switch Series is a line of class 1 laser devices.

brackets and trays. To do so, put the switch on the support tray and slide the switch to an appropriate location, and then fix the mounting brackets.

Mounting the switch on a workbench

In many cases, standard 19-inch racks are not available. Therefore, switches are often placed on clean workbenches. To place the switch on a workbench, follow these steps:

Page 33

Step1 Place the switch with bottom up carefully, and then clean the round holes on the chassis bottom with dry

cloth.

Step2 Attach the rubber feet to the four round holes on the chassis bottom. Step3 Place the switch with upside up on the workbench.

During the operation, you simply need to follow these guidelines:

• Make sure that the workbench is flat and sturdy.

• Ensure good ventilation and a space of 10 cm (3.94 in) around the chassis for heat dissipation.

• Avoid heavy objects on the switch.

Figure 29 Expansion screw

Installation procedure

Follow these steps to mount the switch to a wall:

Step1 As shown in Figure 30, drill two holes 5 mm (0.20 in) across in the wall on the same horizontal line, with

a distance of X mm.

Page 34

NOTE:

Figure 30 Hole distance

Xmm

• The distance X between holes varies with devices. For specific distances, see

Table 15.

• Drill two holes according to the sizes of anchor kits and screws so that anchor kits could go into the

holes, only the edges could remain outside the wall, and the screws could be fixed on the wall tightly.

Step2 Insert anchor kits into the holes and keep only the edges outside the wall, as shown in Figure 31. Step3 Drive screws into the anchor kits, keeping the inside of screw head at least 1.5 mm (0.06 in) away from

the edge of the anchor kit so that the switch could hang on the screws securely.

Figure 31 Install the expansion screws

NOTE:

When you drive the screw to the anchor kit, the front end

of the anchor kit expands to press against the

hole so that the screw can be fixed on the wall.

Step4 Align the two installation holes at the bottom of the switch with these two screws to hang the switch, as

CAUTION:

• Apply magnet mounting to only the above two models. Otherwise, a falloff or mis-operation may occur.

• Select the installation location carefully. In the case of poor surface, magnet mounting may not be

reliable.

• Put the switch at a stable place free from vibrations or shocks. Otherwise, personal injuries or equipmen

damage may occur.

• Avoid installing the switch at a high place because bodily injuries or equipment dama

e may occur in

case of a falloff.

• Avoid frequently moving the desk-mounted switch because such movements may damage the surface

coating.

• To install the device vertically, keep the front panel of the switch facing downwards and the two sides

with ventilation holes vertical to the ground.

• Make sure that the weight of external cables does not bring about a falloff, which may result in bodil

injuries or equipment damage.

• Keep magnetic cards away from magnets to avoid erasure of any information.

• Keep computers and monitors that are easily influenced by magnetic fields away from magnets.

Otherwise, faults may occur to these electronic devices.

Page 37

Connecting the grounding cable

CAUTION:

• Correctly connecting the switch grounding cable is crucial to the lightning protection and

electromagnetic susceptibility (EMS) of a switch.

• The power interface and grounding terminals in this section are for illustration only.

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.

When a grounding strip is available

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 (the grounding screw and the grounding hole are on the rear panel of the switch and are marked with a grounding sign). To do this, follow these steps:

Step1 Remove the grounding screw from the rear panel of the switch chassis. Step2 Put the supplied OT terminal of the grounding cable on the grounding screw. Step3 Fasten the grounding screw, which is attached with the OT terminal of the grounding cable, into the

grounding screw hole with a screwdriver.

Figure 35 Connect the grounding cable to the grounding hole of switch

(1) Rear panel of the switch (2) Grounding sign (3) Grounding hole (4) OT terminal (5) Grounding cable (6) Grounding screw

To attach the other end of the grounding cable to the grounding strip in the equipment room, follow these steps:

Page 38

Step4 Cut the grounding cable to a proper length according to the distance between the switch and the

grounding strip.

Step5 Peel 5 mm (0.20 in) of insulation sheath, and then insert the naked metal part through the insulation

covering into the end of the OT terminal.

Step6 Secure the metal part of the cable to the OT terminal with a crimper, and then cover it with the insulation

covering. Then heat the insulation covering with a blower to make it completely cover the metal part.

Step7 Connect the OT terminal to the grounding pole of the grounding strip, and then fasten it with a hex nut.

Figure 36 Connect the grounding cable to the grounding strip

(1) Grounding post (2) Grounding strip (3) Grounding cable (4) Hex nut

CAUTION:

• Only the grounding cables supplied with the S5120-28P-HPWR-SI and S5120-28P-PWR-SI provide OT

terminals at the ends connecting the grounding strip. For other switch models, prepare proper OT terminals by yourself.

• The fire main and lightning rod of a building are not suitable for grounding the switch. The

cable of the switch should be connected to the grounding device for the equipment room.

Where a grounding conductor can be buried

When there is no grounding strip, but an area with exposed earth is available nearby where a grounding conductor can be buried, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube into the earth. The angle iron should have a dimension no less than 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in) and the steel tube should have a wall thickness no less than 3.5 mm (0.14 in) and be zinc-coated. Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.

Loading software

Introduction

The S5120-SI Switch Series does not provide independent Boot ROM program but integrates it with the application program in host software package with the extension name of .bin.

• Loading boot files: Download the host software package to the flash memory on the switch and set

the attribute (main, backup, or none) of the boot files.

• Upgrading the Boot ROM program: Use Boot ROM files in the host software package to upgrade

the Boot ROM program of the switch.

NOTE:

The entire Boot ROM program consists of the basic segment and extended segment.

• The basic segment is used for basic initialization of the system.

• The extended segment provides abundant human-computer interaction (HCI) functions and available

network interfaces. It can be used to upgrade the applications and boot the system.

Boot ROM program (stored together with application programs in the host software package with an extension name of .bin) used for upgrade are complete Boot ROM program.

• The procedures for loading Boot ROM files and boot files are similar except that you need to select

different items (1 for loading boot files, and 6 for loading Boot ROM files) in the Boot ROM menu. This document takes the loading of Boot ROM files as examples.

Loading files by using XMODEM through the console port

Introduction to XMODEM

XMODEM is a file transfer protocol widely used for its simplicity. XMODEM transfers files through the console port, supporting data packets of 128 bytes. With respect to reliability, it supports checksum, CRC, and the error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is 10.

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.

Loading a Boot ROM file

Loading files at the CLI

By connecting a terminal to the switch, you can load the Boot ROM and boot files of the switch remotely at the CLI.

Loading files by using FTP

Run FTP Server on the local host, configure username admin and the password, and specify the path of the file to be downloaded (suppose the IP address of the FTP server is 10.10.110.1). Then, telnet to the switch and send the host program file to the switch using FTP.

Assume the Boot ROM and boot files are stored in the file named update.bin, follow these steps after you telnet to the switch.

Step1 Download the file to the switch by using FTP.

<H3C> ftp 10.10.110.1 Trying ... Press CTRL+K to abort Connected. 220 WFTPD 2.0 service (by Texas Imperial Software) ready for new user User(none):admin 331 Give me your password, please Password: 230 Logged in successfully [ftp] get update.bin update.bin [ftp] bye

with the attribute, the attribute

Step2 Load the Boot ROM file.

<H3C> bootrom update file update.bin This command will update bootrom file on the specified board(s), Continue? [Y/N]:y Now updating bootrom, please wait...

Step3 Load the boot file, and specify the file as the main boot file.

<H3C> boot-loader file update.bin main This command will set the boot file. Continue? [Y/N]:y The specified file will be used as the main boot file at the next reboot on slot 1! <H3C> display boot-loader Current boot app is: flash:/update.bin Next main boot app is: flash:/update.bin

Page 68

Next backup boot app is: flash:/update.bin <H3C> reboot

NOTE:

• After loading the boot file, use the reboot command to restart the switch to make the upgrade take effec

(make sure you have saved other configurations before restart).

• If the flash memory does not have enough space, load the Boot ROM file first, and then delete certain

boot files from the flash memory (delete the unused host program files); then, load the boot file to the switch through FTP for upgrade.

• Avoid any power failure during the loading process.

Loading files by using TFTP

Loading a file through TFTP is similar to loading a file through FTP. The switch can serve only as a TFTP client that downloads the file from the TFTP server to its flash memory. The procedure after download is the same as loading the file remotely through FTP.

Page 69

Maintenance and troubleshooting

File loading failure

If file loading fails, the system runs steadily by using the original system files. In this case, check whether the physical ports are properly connected.

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

• If so, view the loading procedure information displayed on the HyperTerminal to check for input

errors. If there is any input error, restart the loading procedure with correct input.

Common input errors include:

• Failure to set the baud rate of the HyperTerminal to 9,600 bps when loading files at a baud rate

other than 9,600 bps through XMODEM.

• Entering an incorrect IP address, software name, or path of the TFTP server when using TFTP.

• Entering an incorrect IP address, software name, username, or password when using FTP.

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

Power supply failure

The S5120-28P-HPWR-SI adopts AC power input, RPS power input, or both RPS and AC power inputs. Other S5120-SI switches adopt AC power input only.

You can determine whether the power system of a switch functions properly by viewing the power LED or RPS power LED on the front panel.

With AC power input

When AC power input is used for power supply of a switch, you can check the power LED. The power LED stays on when power system is normal. Otherwise, please check whether:

• The power cord is correctly connected, the power receptacle on the switch and the AC power socket

function normally.

• The power input to the switch is normal.

• The operating temperature of the switch is in the appropriate range and good ventilation is ensured

for the power supply unit. PoE switches support over-temperature protection, allowing the internal power module to enter the protection state if the temperature is too high and then restore power supply after the temperature becomes normal.

With RPS power input

When RPS power input is adopted, you can check the power LED or RPS power LED to judge the status of the power system. Both LEDs stay on when the power system functions normally. Otherwise, please check whether:

• The RPS DC power cord is correctly connected.

• The RPS power supply is normal.

• The operating temperature of the switch is in the appropriate range and good ventilation is ensured

for the power supply unit. PoE switches support over-temperature protection, allowing the internal power module to enter the protection state if the temperature is too high and restore power supply after the temperature becomes normal.

With both AC and RPS power supplies

When both the AC and RPS power supplies are adopted, you can check the power LED and the RPS power LED to determine the status of each power input.

1. The power LED is off.

In this case, both the AC and RPS power inputs are abnormal. Please check that:

• The power cord is correctly connected, the power receptacle on the switch and the AC power socket

function normally.

• The AC power input to the switch is normal.

• The RPS DC power cord is correctly connected and the RPS power supply is normal.

• The operating temperature of the switch is in the appropriate range and a good ventilation is

ensured for the power supply unit. PoE switches support over-temperature protection, allowing the internal power module to enter the protection state if the temperature is too high and then restore power supply after the temperature becomes normal.

2. The power LED is on while the RPS LED is off.

The RPS power input is abnormal, please check that:

• The RPS DC power cord is correctly connected.

Page 71

• The RPS power input is normal.

NOTE:

If the cause cannot be located in the preceding steps and the problem persists, contact your local sales agent or service engineer.

Configuration terminal 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.

Troubleshooting when there is no terminal display

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

• The power supply is normal

• 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.

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). Verify the following terminal parameter (such as hyper terminal) settings:

• Baud rate: 9,600

• Data bits: 8

• Parity: none

• Stop bits: 1

• Flow control: none

• Emulation: VT100.

Appendix A Lightning Protection of the Switch

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.

Figure 59 Diagram of lightning arrester

(1) Working LED (green) On means the circuit is working normally; off means the circuit is

damaged. (2) Grounding/pole detection LED (red) On indicates a wrong wire connection (the wire is not grounded or

the live line and null line are reversely connected), and you need to

check the power supply line. (3) Power switch (4) IEC standard socket It is used to connect to the power supply in the equipment room

through a power cord. (5) Overload automatic protector It can reset automatically. (6) Multifunctional socket It is used to connect the power module of the device.

Page 73

CAUTION:

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

• 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.

• 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 polarit y. 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.
