NOTE:

The available chassis models and accessories vary by country and region. This document describes only the preceding models. For the chassis models and accessories available in your country or region, contact the local H3C marketing personnel.

 

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

·          Before cleaning the switch, remove all power cords from 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 good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.

·          Make sure the power input voltage is as required by the power module.

·          To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.

·          During switch installation, wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably grounded.

Examining the installation site

The switch must be used indoors. You can mount your switch in a rack or on a workbench. Make sure the following requirements are met:

·          Adequate clearance is reserved at the air inlet and outlet vents for ventilation.

·          The rack or workbench has a good ventilation system.

·          Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the switch from the cold aisle and exhausts to the hot aisle.

·          Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the neighboring device from entering the device.

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

·          The rack or workbench is reliably grounded.

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

Temperature/humidity

Maintain temperature and humidity in the equipment room as described in "Appendix A Chassis views and technical specifications."

·          Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.

·          Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure.

·          High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch.

For the temperature and humidity requirements of different switch models, see "Technical specifications"

Cleanliness

Dust buildup on the chassis might 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 1-1 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:

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:

·          A conduction pattern of capacitance coupling.

·          Inductance coupling.

·          Electromagnetic wave radiation.

·          Common impedance (including the grounding system) coupling.

To prevent EMI, use the following guidelines:

·          If AC power is used, use a single-phase three-wire power receptacle with 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.

·          To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.

Grounding the switch

WARNING

WARNING!

Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. For information about lightning protection for the switch, see H3C Lightning Protection Guide.

 

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 (commonly known as PGND). You must securely connect this chassis ground to the earth to minimize the potential for system damage, maximize the safety at the site, and minimize EMI susceptibility of the system.

 

 

NOTE:

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

 

Grounding the switch with a grounding strip

CAUTION

CAUTION:

·      Connect the grounding cable to the grounding strip in the equipment room. Do not connect it to a fire main or lightning rod.

·      To guarantee the grounding effect and avoid switch damage, use the grounding cable provided with the switch to connect the switch to a grounding strip in the equipment room.

 

If a grounding strip is available at the installation site, use the grounding cable provided with the switch to connect the switch to the grounding strip.

Connecting the grounding cable to the chassis

1.        Remove the grounding screw from the grounding hole in the rear panel of the switch chassis.

2.        Use the grounding screw to attach the ring terminal of the grounding cable to the grounding screw hole. Fasten the screw.

 

IMPORTANT

IMPORTANT:

Orient the grounding cable as shown in Figure 2-10 so that you can easily install or remove the removable components.

Installing and removing a fan tray

CAUTION

CAUTION:

·      You can power on the switch only when the switch has two fan trays of the same model installed.

·      Do not leave any slots empty when the switch is operating. Install a module or filler panel in the slots.

·      If both fan trays fail while the switch is operating, replace them within 2 minutes.

·      If one fan tray fails while the switch is operating, perform either of the following tasks:

¡  If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and make sure the failed fan tray is in position before the replacement.

¡  If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.

·      If you power cycle the switch after a fan tray fails, the switch will fail to start up.

 

The switch comes with empty fan tray slots. It supports the LSWM1FANSCE and LSWM1FANSCBE fan trays.

·          The LSWM1FANSCE fan tray provides power module-side intake and port- and chassis-side exhaust airflows. The fan tray handle is blue.

·          The LSWM1FANSCBE fan tray provides port- and chassis-side intake and power module-side exhaust airflows. The fan tray handle is red.

Select the LSWM1FANSCE or LSWM1FANSCBE fan trays for the switch based on the ventilation requirements at the installation site.

Installing a fan tray

1.        Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably grounded.

2.        Unpack the fan tray and verify that the fan tray model is as required.

3.        Orient the fan tray with the TOP mark facing up.

4.        Align the fan tray with the fan tray slot. Holding the fan tray handles, slide the fan tray into the slot along the guide rails. Make sure the fan tray is fully seated in the slot and has a firm contact with the backplane.

To prevent damage to the fan tray or the connectors in the chassis, insert the fan tray gently. If you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.

Figure 2-13 Installing a fan tray

 

IMPORTANT

IMPORTANT:

·      At the first login to the switch, use the fan prefer-direction command to set the airflow direction of the switch to be the same as the airflow direction of the fan trays. If the fan trays have a different airflow direction than the switch, the system outputs traps and logs to notify you to replace the fan trays.

·      By default, the switch uses the same airflow direction (power-to-port) as the LSWM1FANSCBE fan tray.

 

Removing a fan tray

WARNING

WARNING!

·      To avoid bodily injury, disturbing the dynamic balance of the fan tray, and causing loud noises, do not touch the rotation axis, or any bare wires, fan blades, or terminals on the fan tray.

You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs.

The following are the required terminal settings:

·          Bits per second—9,600.

·          Data bits—8.

·          Parity—None.

·          Stop bits—1.

·          Flow control—None.

Starting the switch

Pre-start checklist

Before powering on the switch, verify the following items:

·          The power cord is correctly connected.

·          The input power voltage is as required by the switch.

·          The console cable is correctly connected.

·          The PC has started, and the terminal parameters have been correctly configured.

Powering on the switch

During the startup process, you can access Boot ROM menus to perform tasks such as software upgrade and file management. The Boot ROM interface and menu options differ with software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device.

After the startup process is completed, you can access the CLI to configure the switch.

4 Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S6520X-EI or S6520X-HI switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

An S6520X-EI or S6520X-HI switch can set up an IRF fabric only with switches from the same switch series.

IRF fabric setup flowchart

Figure 4-1 IRF fabric setup flowchart

 

To set up an IRF fabric:

 

Step

Description

1.       Plan IRF fabric setup

Plan the installation site and IRF fabric setup parameters:

·         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" and "Connecting the power cord."

4.       Power on the switches

N/A

5.       Configure basic IRF settings

See H3C S6520X-EI & S6520X-HI Switch Series Virtual Technologies Configuration Guide, depending on the software version.

6.       Connect the physical IRF ports

Connect physical IRF ports on switches.

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

 

Planning IRF fabric setup

This section describes issues that an IRF fabric setup plan must cover.

Planning IRF fabric size and the installation site

Choose 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 to implement the ToR access solution for a data center.

 

 

NOTE:

For the maximum IRF member devices supported by the switch, see the release notes that come with the switch.

 

Identifying the master switch and planning IRF member IDs

Determine which switch you want to use as the master for managing all member switches in the IRF fabric.

An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the CLI of the master switch. IRF member switches 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 H3C S6520X-EI & S6520X-HI Switch Series Virtual Technologies 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 reliable ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Instead, the IRF fabric changes to a daisy chain topology without interrupting network services.

You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind a minimum of one physical port to it.

When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.

The switch can provide 5G/10GE/25G/40GE/100GE IRF connections. See Table 4-1 for the available IRF physical ports. You can bind several IRF physical ports to an IRF port for increased bandwidth and availability.

Figure 4-2 and Figure 4-3 show the topologies of an IRF fabric made up of three S6520X-54QC-EI switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure 4-2 IRF fabric in daisy chain topology

 

Figure 4-3 IRF fabric in ring topology

 

Identifying physical IRF ports on the member switches

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

Table 4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.

·          For the cables used for connecting 5G/2.5G/1000BASE-T and 10G/5G/2.5G/1000BASE-T autosensing Ethernet ports, see "Appendix C Ports and LEDs."

For a short-distance IRF connection in an equipment room, use a twisted pair/SFP+/QSFP+/SFP28/QSFP28 cable.

For a long-distance IRF connection, use SFP+/QSFP+/SFP28/QSFP28 transceiver modules and optical fibers.

The following subsections describe several H3C recommended IRF connection schemes by using SFP+ cables and SFP+ transceiver modules and fibers. All these schemes use a ring topology.

 

IMPORTANT

IMPORTANT:

In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different sides, you must measure the distance between them to select an appropriate cable.

 

Connecting the IRF member switches in one rack

Connect the IRF member switches (9 switches in this example) in a rack as shown in Figure 4-4. The switches in the ring topology (see Figure 4-5) are in the same order as connected in the rack.

Figure 4-4 Connecting the switches in one rack

 

Figure 4-5 IRF fabric topology

 

Connecting the IRF member switches in a ToR solution

You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.

Figure 4-6 ToR cabling

 

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see H3C S6520X-EI & S6520X-HI Switch Series 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.

·          To bind the ports on an interface card to an IRF port, you must install the interface card first.

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

For more information about configuring basic IRF settings, see H3C S6520X-EI & S6520X-HI Switch Series Virtual Technologies Configuration Guide.

Connecting the physical IRF ports

Use twisted pair/SFP+/QSFP+/SFP28/QSFP28 cables or SFP+/QSFP+/SFP28/QSFP28 transceiver modules and fibers to connect the IRF member switches as planned.

Wear an ESD wrist strap when you connect twisted pair/SFP+/QSFP+/SFP28/QSFP28 cables or SFP+/QSFP+/SFP28/QSFP28 transceiver modules and fibers. For how to connect them, H3C Transceiver Modules and Network Cables Installation Guide.

Verifying the IRF fabric setup

To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF ports:

1.        Log in to the IRF fabric through the console port of any member switch.

2.        Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other.

3.        Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (See H3C S6520X-EI & S6520X-HI Switch Series Fundamentals Configuration Guide.)

4.        Verify that you can manage all member switches as if they were one node.

5.        Display the running status of the IRF fabric by using the commands in Table 4-2.

Connecting cables to the ports on interface cards

To connect cables to the ports on interface cards, follow these guidelines:

·          Do not bundle cables in their first 20 m (65.62 ft).

·          Separate power cords and twisted pair cables at and around the distribution frame.

·          For ports adjacent to one another on the device, the peer ports on the distribution frame is preferably not adjacent, for example:

·          If the device connects to one distribution frame, connect port 1 on the device to port 1 on the distribution frame and port 2 on the device to port 3 on the distribution frame.

·          If the device connects to two distribution frames, connect port 1 on the device to port 1 on distribution frame 1 and port 2 on the device to port 1 on distribution frame 2.

·          Keep the device and cables away from the interference source, such as a two-way radio and a high-power variable-frequency drive.

IMPORTANT

IMPORTANT:

·      A QSFP-100G-SR4-MM85 transceiver module supports one-to-four splitting. You can use it to connect a 100G QSFP28 port to four 25G SFP28 ports. The QSFP28 transceiver module and SFP28 transceiver modules to be connected must be the same in specifications, including central wavelength and fiber type.

·      QSFP28 ports do not support QSFP+ to SFP+ cables and cannot be split to 10GE ports by using QSFP+ transceiver modules.

 

 

NOTE:

·      As a best practice, use H3C transceiver modules and network cables for the switch.

·      The H3C transceiver modules and network cables are subject to change over time. For the most recent list of H3C transceiver modules and cables, contact H3C Support or marketing staff.

·      For the specifications of H3C transceiver modules and network cables, see H3C Transceiver Modules User Guide.
