Preparing for installation

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installing an H3C S3100V2-52TP switch. Note that the recommendations do not cover every possible hazardous condition.

• Before cleaning the switch, unplug the power cord of the switch. 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 severely damaged 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 in the range labeled on the switch.

• To avoid electrical shocks, do not open the chassis when the switch is operating or when the switch

is just powered off.

• When replacing interface cards, hot-swappable power modules and fan trays, wear an

ESD-preventive wrist strap to avoid damaging the units.

Examining the installation site

The H3C S3100V2-52TP Switch must be used indoors. You can mount the switch in a rack or on a workbench, but make sure:

• Adequate clearance is reserved at the air inlet and 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 earthed.

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

Page 9

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 significantly lowers reliability and service life of the switch.

For the temperature and humidity requirements of this switch, see Table 6.

Cleanness

Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure.

Table 1 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m³)

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

NOTE:

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

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 2.

Table 2 Harmful gas li

mits in the equipment room

Gas Maximum concentration (mg/m

)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions:

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

protection earth (PE) to 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.

Page 10

Laser safety

The H3C S3100V2-52TP Switch is a line of Class 1 laser devices.

CAUTION:

Do not stare into any fiber port when the switch has power. The laser li

ht emitted from the optical fiber

may hurt your eyes.

Installation tools

• Flat-blade screwdriver

• Phillips screwdriver

• ESD-preventive wrist strap

All these installation tools are user supplied.

Page 14

IMPORTANT:

• Ensure good ventilation and 10 cm (3.9 in) of clearance around the chassis for heat dissipation.

• Avoid placing heavy objects on the switch.

Grounding the switch

WARNING!

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

NOTE:

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

The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground. You must securely connect this chassis ground to the earth so that the faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the switch.

You can ground the switch in one of the following ways, depending on the grounding conditions available at the installation site:

• Grounding the switch with a grounding strip

• Grounding the switch with a grounding conductor buried in the earth ground

• Grounding the switch with the PE wire of an AC power supply

Grounding cable

The S3100V2-52TP Switch is provided with a yellow-green grounding cable. One end of the cable has an OT terminal, and the other end is naked and soldered, as shown in Figure 8.

Connecting the grounding cable to a grounding strip

Follow these steps to connect the grounding cable to a grounding strip:

Step1 Remove the hex nut from the grounding strip. Step2 Cut the grounding cable to a proper length according to the distance between the switch and the

grounding strip.

Step3 Make the connector on the grounding cable:

• If you have an OT terminal, follow callout A in Figure 10 t

o make the connector: Peel 5 mm (0.20 in) of insulation sheath by using a wire stripper, and then insert the naked metal part through the insulation covering into the end of the OT terminal. 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.

Page 16

• If you do not have an OT terminal, follow callout B in Figure 10 to make the connector: Peel the

insulation s h e a t h by an appropriate length by using a wire stripper, and then bend the naked metal part.

Step4 Connect the made connector to the grounding post of the grounding strip, and then fasten it with a hex

nut, as shown in Figure 11.

Setting up an IRF fabric

You can use H3C Intelligent Resilient Framework (IRF) technology to connect and virtualize S3100V2-52TP switches into a virtual switch called an “IRF fabric” or “IRF virtual device” for flattened network topology, and high availability, scalability, and manageability.

This chapter includes these sections:

• IRF fabric setup flowchart

• Planning IRF fabric setup

• Configuring basic IRF settings

• Connecting the physical IRF ports

• Accessing the IRF fabric to verify the configuration

Follow these steps to set up an IRF fabric:

Step Description

1. Plan IRF fabric setup

Plan the installation site and IRF fabric setup parameters. Complete the following tasks:

• Planning IRF fabric size and the installation site

• Identifying the master switch and planning IRF member IDs

• Planning IRF topology and connections

• Identifying physical IRF ports on the member switches

• Planning the cabling scheme

2. Install IRF member

switches

See “Installing the switch in a 19-inch rack” or “Mounting the switch on a

workbench.”

3. Connect ground wires

and power cords

See “Grounding the switch” or “Connecting the power cord.”

4. Power on the switches

N/A

5. Configure basic IRF

settings

For more information about IRF, see the H3C S3100V2-52TP Switch IRF Configuration Guide.

6. Connect the physical IRF

ports

Connect physical IRF ports on switches. Use Ethernet cables, SFP transceiver modules, and fibers to connect ports over a long distance, or use SFP IRF modules to connect ports over a short distance.

All switches except the master switch automatically reboot, and the IRF fabric is established.

Planning IRF fabric setup

Planning IRF fabric size and the installation site

Choose S3100V2-52TP switch models and identify the number of required IRF member switches, depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of all member switches.

Plan the installation site depending on your network solution, as follows:

• Place all IRF member switches in one rack for centralized high-density access.

• Distribute the IRF member switches in different racks for dispersed access.

NOTE:

An IRF fabric can have up to nine S3100V2-52TP switches. As your business grows, you can plug an S3100V2-52TP switch into an IRF fabric to increase the switchin

capacity without any topology change

or replacement.

Identifying the master switch and planning IRF member IDs

Determine which switch you want to use as t he master for mana g ing all m e mber swi t ches in the IR F fabric. An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the command line interface of the master switch.

Page 32

NOTE:

IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see the

H3C S3100V2-52TP Switch IRF Configuration Guide

Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID.

Planning IRF topology and connections

You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.

You connect the IRF member switches through IRF ports. An IRF port is a logical interface for the internal connection between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. An IRF port is activated when you bind a physical port to it.

When connecting IRF member switches, you must connect the physical ports of IRF-port1 on one switch to the physical ports of IRF-port2 on its neighbor switch.

The S3100V2-52TP switches can provide IRF connections through the GE Ethernet ports and GE SFP ports, and you can bind several GE ports to an IRF port for increased bandwidth and availability.

NOTE:

• Figure 24 an

d Figure 25 show the topologies for an IRF fabric made up of three S3100V2-52TP

switches.

• The IRF port connections in the two fi

ures are for illustration only, and more connection methods are

available.

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection scheme.

When using a combo interface for IRF connection, configure the fiber or copper port of the combo interface as active. For how to configure the combo interface state, see the H3C S3100V2-52TP Switch Layer 2—LAN Switching Configuration Guide.

Planning the cabling scheme

Use GE Ethernet twisted pairs, SFP IRF modules or SFP transceiver modules, and fibers to connect the IRF member switches. If the IRF member switches are far away from one another, choose GE Ethernet twisted pairs or the SFP transceiver modules with optical fibers. If the IRF member switches are all in one rack, choose SFP IRF modules.

Table 10

Lists the SFP transceiver modules and SFP IRF modules available for IRF connections.

The following subsections describe several IRF connection schemes and use SFP IRF modules or SFP transceiver modules with optical cables for example. All these schemes use a ring topology.

Connecting the IRF member switches in one rack

NOTE:

This example uses nine switches.

You can connect the IRF member switches in one rack (see Figure 26), and Figure 27 shows the IRF fabric topology.

Connecting the IRF member switches in different racks

NOTE:

This example uses nine switches.

You can install IRF member switches in different racks side by side. Figure 28 shows an example for connecting nine IRF member switches in different racks, and Figure 27 sh

ows the IRF fabric topology.

Figure 28 Connect the IRF member switches in different racks

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see the H3C S3100V2-52TP Switch Fundamentals Configuration Guide) to configure their member IDs, member priorities, and IRF port bindings.

Follow these guidelines when you configure the switches:

• Assign the master switch higher member priority than any other switch.

• Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You perform

IRF port binding before or after connecting IRF physical ports depending on the software release.

• Execute the display irf configuration command to verify the basic IRF settings.

For more information about configuring basic IRF settings, see the H3C S3100V2-52TP Switch IRF Configuration Guide.

Connecting the physical IRF ports

Connect IRF member switches with GE Ethernet cables, SFP IRF modules or SFP transceiver modules, and fibers as planned.

Page 36

NOTE:

Wear an ESD-preventive wrist strap when you connect SFP IRF modules or SFP transceiver modules and fibers. For how to connect them, see the

H3C Pluggable SFP/SFP+/XFP Transceiver Modules Installatio

Guide

Accessing the IRF fabric to verify the configuration

When you are finished configuring basic IRF settings and connecting IRF ports, follow these steps to verify the basic functionality of the IRF fabric:

Step1 Log in to the IRF fabric through the console port of any member switch. Step2 Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the remote

network management station can reach each other.

Step3 Use Telnet, web or SNMP to access the IRF fabric from the network management station. (See the H3C

S3100V2-52TP Switch Fundamentals Configuration Guide.)

Step4 Check that you can manage all member switches as if they were one node. Step5 Display the running status of the IRF fabric by using the commands in Table 4.

Maintenance and troubleshooting

Software loading failure

The switch runs with the original software version after it has failed to load new version of software. To identify and remove the loading failure cause, perform the following check procedure:

• Check that the physical ports are properly connected.

• If the physical connection is loose or incorrect, reconnect the physical ports and make another try

to load software.

• If the physical connection is secure and correct, view the loading procedure information displayed

on the HyperTerminal to check for input errors, and make another try to load software.

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 software loading fails for any other cause than physical connection problems and input errors, please contact your sales agent for help.

Boot ROM password loss

Contact your sales agent for help.

Power system failure

The switch uses the system status LED (PWR) on the front panel to show how the power system of the switch is operating. If the system status LED is off, a power supply failure has occurred. Check the following items:

• The power cord is well connected to the switch, and the AC receptacle on the switch and the AC

power receptacle are normal.

• The external AC power supply system is operating properly.

• The operating temperature of the switch is normal, and the power module has good ventilation

(over-temperature can cause a power module to stop working and enter the protection state).

NOTE:

If the problem persists, contact your local sales agent or service engineer.

Fan failure

You can look at the system status LED and the seven-segment LED of an S3100V2-52TP switch to identify a fan failure. If both LEDs are behaving as described in Table 5,

a fan failure occurs.

Table 5 LED behaviors for fan failure

LED Mark State

System status LED PWR Steady red

Seven-segment LED Unit

The LED displays F for fan failure.

The S3100V2-52TP Switch uses fixed fans. If a fixed fan failure occurs, you cannot solve the problem yourself. Contact your sales agent or service engineer.

NOTE:

To ensure the normal operation of the switch, contact the local sales a

ent or service engineer as soon as

possible when a fixed fan failure occurs.

Page 39

Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays booting information when the switch is powered on. If the setup is incorrect, the configuration terminal would display nothing or garbled text.

No terminal display

If the configuration terminal displays nothing when the switch is powered on, check that:

• The power supply is normal.

• The console cable is properly connected.

• The console cable has no problem and the terminal settings are correct.

Garbled terminal display

If terminal display is garbled, check that the following settings are configured for the terminal, for example, HyperTerminal:

• Baud rate—9,600

• Data bits—8

• Parity—none

• Stop bits—1

• Flow control—none

• Emulation—VT100
