Chapter 2  Installation Preparation

2.1  Safety Precautions

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

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

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

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

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

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

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

2.2  Installation Site

The S5510 series must be used indoors. You can mount your switch in a rack or on a tabletop/workbench, but make sure:

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

l           The rack or table/workbench has a good ventilation system.

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

l           The rack or table/workbench 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 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 1.4  Technical Specifications of S5510 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 the following table:

Table 2-1 Dust content limits in an equipment room

Substance	Unit	Content
Dust	Particles/m³	≤ 3 X 104 (No visible dust on the tabletop for three days)
Remark: the diameter of a dust particle ≥ 5μm

 

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 the following table.

Table 2-2 Harmful gas limits in the equipment room

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

 

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:

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

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

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

l           Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.

2.2.4  Laser Safety

The S5510 series are class-1 laser devices.

When the optical ports on your S5510 switch are operating, do not stare into the optical ports because the laser light emitted by the optical fiber can hurt your retina.

 

 

2.3  Installation Tools

l           Flat-blade screwdriver

l           Phillips screwdriver

l           ESD-preventive wrist strap

3.1.2  Desk Mounting

When a 19-inch standard cabinet is not available, you can simply place the switch on a clean desk. When doing so, you should ensure that:

l           The desk is stable and well grounded.

l           A clearance about 10 cm (3.9 in) is reserved around the switch for heat dissipation.

l           No heavy object is placed on the switch.

3.2  Installing Power Module

 

 

3.2.1  Installing a Power Module

Step 1: Draw on the ESD-preventive wrist strap and ensure that the strap is well grounded.

Step 2: Remove the dummy panel from the power slot.

Step 3: Keeping the power module to be installed in the right direction, with one hand taking hold of the handle before the module and the other hand holding the module on the palm, smoothly slide the module into the power slot until the plug on the module completely fits into the socket in the chassis. Note that, the right direction is that the letters on the module is in the up direction; if you install the module with upset down, being restricted by the specially-designed structure inside the chassis, you will not be able to completely insert the module into the slot.

Step 4: Fasten the captive screws at both sides of the power module with a Phillips screwdriver.

3.2.2  Removing a Power Module

Step 1: Draw on the ESD-preventive wrist strap and ensure that the strap is well grounded.

Step 2: Power down the module to be removed.

Step 3: Loosen the captive screws at both sides of the power module with a Phillips screwdriver.

Step 4: With one hand taking hold of the handle before the power module to be removed and the other hand press down on the top of the switch, pull the module completely out off the socket in the chassis and smoothly out of the power slot.

 

 

3.3  Connecting the Power Cord and the Ground Wire

3.3.1  Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)

You are recommended to use a monophase three-line power socket with a ground contact or a general purpose PC power socket, making sure that the power point is well connected to building ground. Normally, the ground point of the power source in a building was buried in the ground during the construction and wiring. Still, you must make sure of that.

Figure 3-14 Power socket (recommended)

II. Connecting the AC-input power cord

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear of the chassis and the other end to the ground as near as possible.

Step 2: Connect one end of the power cord to the power socket on the rear of the chassis, and plug the other end to the AC power jack of the power source.

Step 3: Verify that the PWR LED on the front panel of the switch is ON.

 

 

3.3.2  Connecting the DC-Input Power Cord

+: -48V working ground

-: -48 to -60 V

NULL: reserved

Figure 3-15 DC-input power connector (partial)

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear of the chassis and the other end to the ground as near as possible.

Step 2: Directly insert the component into DC-input socket on the cabinet, and then fix the screws 1 and 2 carried by the connector itself to the appropriate holes on the cabinet socket using a small flathead screwdriver, see Figure 3-16.

Figure 3-16 Illustration for fixing RPS connector to the cabinet

Step 3: Verify that the power LED PWR1/PWR2 on the front panel of the switch is ON.

 

 

3.3.3  Connecting the Ground Wire

 

 

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:

l           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.)

(1) Power input on the switch	(2) Grounding screw on the switch
(3) Ground wire	(4) Grounding strip

Figure 3-17 Grounding the switch through a grounding strip

l           When there is no grounding strip but earth near the equipment room that allows a grounding body to be buried, hammer an angle iron/steel pipe longer than 0.5 m into the earth, weld the yellow-green ground wire of the switch onto the angle iron/steel pipe, and process the joint against erosion.

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.

 

 

5.2  Loading Software Locally

If your terminal is directly connected to the switch, you can load Boot ROM and host software locally. But before that, make sure they are correctly connected.

5.2.2  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.

The app to boot at the next time is: flash:/SWITCH.bin

<H3C> reboot

 

 

To validate the downloaded Boot ROM and host software, you must reboot the switch. In case of inadequate Flash memory space, you can delete some of the program files in Flash, those that are no longer in use for example, after completing Boot ROM loading. Then FTP the host program to the switch.

 

 

5.3.2  Loading Software Remotely Using TFTP

TFTP is similar to FTP in remote software downloading. But with TFTP, the switch can only be used as the client to download software to its Flash memory from the TFTP server. After that, the remaining steps are the same as remote loading using FTP.

 

Chapter 6  Maintenance and Troubleshooting

6.1  Dealing with Loading Failures

If software loading fails, the system operates with the original version.

To address the failure cause, take these steps:

1)         Verify that the physical ports are correctly and securely connected. If they are not, reconnect them correctly and restart loading.

2)         Check information about the loading procedures for input errors on the HyperTerminal.

l           If XModem is used, verify that you have reset the baud rate of the HyperTerminal to 9600 bps after loading the software with another baud rate.

l           If TFTP is used, verify that you have correctly specified the TFTP parameters: server and switch IP addresses; name of the software to be loaded; and path for the TFTP server to operate on program files.

l           If FTP is used, verify that you have correctly specified the FTP parameters: server and switch IP addresses; name of the software to be loaded; and username and password.

3)         Contact your sales agent for help if you cannot address the problem after taking the preceding two steps.

6.2  Dealing with Password Loss

6.2.1  Dealing with User Password Loss

If you lost your user password, enter the Boot Menu first:

       BOOT  MENU

 

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):

Select <7> and have the switch reboot. The user password is deleted at the reboot to allow you access the switch without password.

6.2.2  Recovering the Boot ROM Password

Contact your sales agent for help.

6.3  Dealing with Power System Failures

You can know whether the power system has failed by reading the power LED (PWR) on the front panel. If the power system is operating normally, the power LED is constant ON. If not, verify that:

l           The switch power cord is correctly connected.

l           The power source can work with the switch.

6.4  Dealing with Configuration System Failures

If the switch is operating normally after it is powered up, it displays the start-up information on the console terminal. If the configuration system has failed, it displays illegible characters or nothing at all.

I. No information on the terminal

Take these steps to address the problem:

1)         Verify that:

l           The power system is operating normally.

l           The console cable is connected correctly.

2)         Verify that the console cable is in good condition and the terminal (HyperTerminal for example) parameter settings are correct.

II. Illegible characters on the terminal

Make sure you have set on your terminal (HyperTerminal):

Baud rate = 9600

Data bits = 8

Parity check = none

Stop bits = 1

Flow control = none

Terminal emulation = VT100

Reconfigure the parameters if their values are different.
