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 operating voltage is in the required range.

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

·     When installing the switch, wear an ESD wrist strap and make sure it 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, but make sure:

·     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 and humidity

Maintain temperature and humidity in the equipment room at acceptable ranges.

·     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 in Hardware Information and Specifications.

Cleanliness

Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table 1-2 describes the dust concentration limits in the equipment room for the S5560S-EI switch series. Table 1-3 describes the dust concentration limits in the equipment room for the S5130S-HI switch series.

Grounding the switch

	WARNING! ·     Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. ·     As a best practice to guarantee the grounding effect, ground the switch by connecting the grounding cable provided with the switch to the grounding strip in the equipment room.

 

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.

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

 

	NOTE: ·     The power and grounding terminals in this section are for illustration only. ·     For more information about lightning protection, see H3C Lightning Protection Guide.

 

Grounding the switch with a grounding strip

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

 

If a grounding strip is available at the installation site, connect the grounding cable to the grounding strip.

Connecting the grounding cable to the chassis

1.     Remove the grounding screw from 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.

Connecting the grounding cable to a grounding strip

1.     Cut the grounding cable to a length required for connecting to the grounding strip.

2.     Use a wire stripper to strip 20 mm (0.79 in) of insulation off the end of the grounding cable. Then use needle-nose pliers to bend the bare metal part to the shape as shown in Figure 2-17. Make sure the bended part can securely attached to the grounding post on the grounding strip.

3.     Attach the bended part of the grounding cable to the grounding post and use the hex nut to fasten the bended part to the post.

(3) Grounding cable	(4) Hex nut

 

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

If the installation site does not have any grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube into the earth ground to serve as a grounding conductor.

The dimensions of the angle iron must be a minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel tube must be zinc-coated and its wall thickness must be a minimum of 3.5 mm (0.14 in).

Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.

3 Accessing the switch for the first time

Connecting the switch to a configuration terminal

You can connect the switch to a configuration terminal by using the serial console port or the micro USB console port. Only the micro USB console port takes effect if you connect both the serial console port and micro USB console port.

In Figure 3-1, the switch is connected to a configuration terminal (PC as an example) from the serial console port.

Figure 3-1 Connecting the switch to a configuration terminal

 

As shown in Table 3-1, three types of console cables can be used for connecting the switch to a configuration terminal. As a best practice, use a serial console cable for connection. The switch is not provided with a serial console cable or a micro USB console cable. Prepare an H3C console cable or prepare a micro USB console cable yourself.

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.

Configure the terminal parameters as follows:

·     Bits per second—9,600.

·     Data bits—8.

·     Parity—None.

·     Stop bits—1.

·     Flow control—None.

Powering on the switch

Before powering on the switch, verify that the following conditions are met:

·     The power cord is correctly connected.

·     The input power voltage meets the requirement of the switch.

·     The console cable is correctly connected.

·     The PC has started, and its serial port settings are consistent with the console port settings on the switch.

Power 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 completes, you can access the CLI to configure the switch.

For more information about the configuration commands and CLI, see the configuration guides and command references for the switch series.

4 Setting up an IRF fabric

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

Only switches of the same series support IRF connection.

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 IRF physical 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 the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.
6.     Connect the IRF physical ports	Connect IRF physical 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 the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.

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 form an IRF fabric only with switches from the same switch series. For the physical ports that can be used for IRF connections on each switch model and the restrictions for using the ports, see Table 4-1. The IRF physical ports can set up IRF connections only when operating at their highest speeds. For example, a 10-GE port must operate at 10 Gbps. A GE port must operate at 1 Gbps.

Figure 4-2 and Figure 4-3 show the topologies of an IRF fabric made up of three S5130S-52S-HI 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 IRF physical ports on the member switches

Identify the IRF physical 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.

Table 4-1 IRF physical ports and use restrictions

Device model	Candidate IRF physical ports	Restrictions for using the ports for IRF connections
S5560S-28F-EI S5560S-28S-EI S5560S-28S-PWR-EI S5130S-28S-HI S5130S-28S-PWR-HI S5130S-28S-UPWR-HI S5560S-52F-EI S5560S-52S-EI S5560S-52S-PWR-EI S5130S-52S-HI S5130S-52S-PWR-HI	The following ports on the front panel: ·     Four SFP+ ports ·     10/100/1000BASE-T autosensing ports (supported only in F630x and later) ·     SFP ports (supported only in F630x and later)	The port must operate at its highest speed. ·     SFP+ port—10 Gbps ·     10/100/1000BASE-T autosensing port—1 Gbps ·     SFP port—1 Gbps All physical ports to be bound to an IRF port must have the same data rate. For a 52-port switch model, the 52 ports are divided into two groups: ports 1 to 24, port 51, and port 52 in one group and ports 25 to 50 in the other group. To bind multiple ports to an IRF port, make sure the ports are in the same group. The ports in one group can be bound to different IRF ports.
S5560S-28P-EI S5560S-52P-EI	The following ports on the front panel: ·     10/100/1000BASE-T autosensing Ethernet ports ·     SFP ports	The ports must operate at 1 Gbps. For a 52-port switch model, the 52 ports are divided into two groups: ports 1 to 24, port 51, and port 52 in one group and ports 25 to 50 in the other group. To bind multiple ports to an IRF port, make sure the ports are in the same group. The ports in one group can be bound to different IRF ports.
S5130S-28C-HI S5130S-28C-PWR-HI S5130S-52C-HI S5130S-52C-PWR-HI	The following ports on the front panel and the expansion module: ·     10/100/1000BASE-T autosensing Ethernet ports ·     SFP ports ·     SFP+ ports	The port must operate at its highest speed. ·     SFP+ port—10 Gbps ·     10/100/1000BASE-T autosensing port—1 Gbps ·     SFP port—1 Gbps All physical ports to be bound to an IRF port must have the same data rate. For a 52-port switch model, the 52 ports are divided into two groups: ports 1 to 24, port 51, and port 52 in one group and ports 25 to 48 and ports on the expansion module in the other group. To bind multiple ports to an IRF port, make sure the ports are in the same group. The ports in one group can be bound to different IRF ports.

 

Planning the cabling scheme

Use the following cables to connect the IRF physical ports on the switches:

·     10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cable.

·     SFP port—GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver module and twisted pair cable or GE SFP cable. For the available transceiver models and cables, see ports in Hardware Information and Specifications.

·     SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available transceiver models and cables, see ports in Hardware Information and Specifications.

If the IRF member switches are far away from one another, use SFP/SFP+ transceiver modules and optical fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or SFP/SFP+ cables.

As a best practice, use ring topology to connect the switches. The following describes cabling schemes in ring topology by using SFP+ cables and SFP+ transceiver modules and fibers to connect four switches.

Connecting the IRF member switches in one rack

Use SFP+ cables to connect the IRF member switches 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 shows an example for connecting 4 top of rack IRF member switches by using SFP+ transceiver modules and optical fibers. The topology is the same as Figure 4-5.

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 the fundamentals configuration guide for the switch series) 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 IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.

Connecting the IRF physical ports

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

Wear an ESD wrist strap when you connect IRF physical ports. For how to connect SFP/SFP+ cables or SFP/SFP+ transceiver modules and fibers, see H3C SFP/SFP+/XFP/SFP28 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 the fundamentals configuration guide for the switch series.)

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.

Table 4-2 Displaying and maintaining IRF configuration and running status

Task	Command
Display information about the IRF fabric.	display irf
Display all members’ IRF configurations that take effect at a reboot.	display irf configuration
Display IRF fabric topology information.	display irf topology

 

	NOTE: To avoid IP address collision and network problems, configure a minimum of one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.
