To avoid any equipment damage or bodily injury caused by incorrect 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.

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

· 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 replacing FRUs, including power supplies and fan trays, wear an ESD wrist strap to avoid damaging the units.

Examining the installation site

The switch must be used indoors. Mount your switch in a rack and verify the following items:

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

· The rack 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 bottom device from entering the top device.

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

· The rack 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 appropriate temperature and humidity in the equipment room.

· 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 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 "Appendix A Chassis views and 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.

Table1-1 Dust concentration limit in the equipment room

Substance	Particle diameter	Concentration limit
Dust particles	≥ 5 µm	≤ 3 x 10⁴ particles/m³ (No visible dust on desk in three days)
Dust (suspension)	≤ 75 µm	≤ 0.2 mg/m³
Dust (sedimentation)	75 µm to 150 µm	≤ 1.5 mg/(m²h)
Sand	≥ 150 µm	≤ 30 mg/m³

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table1-2.

Table1-2 Harmful gas limits in the equipment room

Gas	Maximum concentration (mg/m3)
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 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.

Laser safety

WARNING!

· The switch is a Class 1M laser device.

· Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the switch is operating.

Installation tools

No installation tools are provided with the switch. Prepare the following tools yourself:

· Phillips screwdriver.

· Flathead screwdriver.

· ESD wrist strap.

· Marker.

Attaching the mounting brackets, chassis rails, and grounding cable to the chassis

The switch has two mounting bracket installation positions on its two side panels: one near the network port side and one near the power supply side.

The switch provides a primary grounding point (with a grounding sign) and an auxiliary grounding point.

The S6805-54HF and S6805-54HT switches are identical in the mounting bracket installation positions and grounding point positions. Figure2-11 describes these positions on the S6805-54HF switch.

Figure2-11 Mounting bracket installation positions and grounding point positions on the S6805-54HF switch

(1) Mounting bracket installation position near the power supply side
(2) Primary grounding point	(3) Auxiliary grounding point
(4) Mounting bracket installation position near the port side

Attaching the mounting brackets and chassis rails to the chassis

IMPORTANT:

M4 screws are used to secure the mounting brackets and chassis rails to the switch. As a best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten M4 screws.

To attach the mounting brackets and chassis rails to the chassis:

1. Place the wide flange of a mounting bracket against a side panel of the chassis and align the round holes in the wide flange of the front mounting bracket with the screw holes in the side panel. Then use M4 screws (provided) to attach the mounting bracket to the chassis.

¡ To install the mounting brackets at the port side, see Figure2-12, Figure2-13, Figure2-14, and Figure2-18.

¡ To install the mounting brackets at the power supply side, see Figure2-15, Figure2-16, Figure2-17, and Figure2-19.

2. Determine the chassis rail installation position based on the mounting bracket installation position.

3. Place the chassis rail against the side panel of the chassis and align the installation holes in the chassis rail with rail mounting holes in the chassis. Then use M4 screws (provided) to attach the chassis rail to the chassis.

¡ For installation of chassis rails of rack mounting rail kit A (long slide rails) and rack mounting rail kit C, see Figure2-12, Figure2-15, Figure2-18, and Figure2-19.

¡ The chassis rails of rack mounting rail kit B (super-short slide rails) support narrow-spacing installation and wide-spacing installation. Select narrow-spacing (as shown in Figure2-13 and Figure2-16) or wide-spacing (as shown in Figure2-14 and Figure2-17) installation based on the distance between the front and rear rack posts.

4. Follow the same procedure to attach another mounting bracket and chassis rail to the opposite side.

Connecting the grounding cable to the chassis

IMPORTANT:

The primary and auxiliary grounding points are located on the left side panel of the chassis. The two grounding points might be not reachable after the switch is mounted in the rack. Connect the grounding cable to a grounding point before you mount the switch in the rack.

Select the primary or auxiliary grounding point as required. The following procedure connects the grounding cable to the primary grounding point (near the power supply side) on an S6805-54HF switch.

To connect the grounding cable to a grounding point:

1. Unpack the grounding cable and grounding screws (applicable to both the primary and auxiliary grounding points).

2. Use the grounding screws to attach the two-hole grounding lug to the grounding point and then fasten the screws, as shown in Figure2-20.

As a best practice, use a torque of 20 kgf-cm (1.96 Nm) to fasten the grounding screws.

Figure2-20 Attaching the grounding cable to the primary grounding point on an S6805-54HF switch

Attaching the slide rails to the rack

IMPORTANT:

M6 screws and cage nuts are used to attach the slide rails to the rack. Prepare M6 screws and cage nuts yourself. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.

Before mounting the switch in the rack, you must attach slide rails to the rack.

The installation procedure is the same for different types of slide rails. The following procedure attaches 1U long slide rails to the rack.

To attach the slide rails to the rack:

1. Identify the slide rail installation position on the rack based on the switch installation position.

2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.

3. Align the screw holes in one slide rail with the cage nuts in a rear rack post, and then use M6 screws (user-supplied) to attach the slide rail to the rack, as shown in Figure2-21.

4. Attach the other slide rail to the rear rack post on the opposite side.

Make sure the two slide rails are at the same height and can slide into the chassis rails smoothly.

Figure2-21 Installing the 1U long slide rails

Mounting the switch in the rack

The rack-mounting procedure is similar for the switches. The following procedure mounts an S6805-54HF switch in a rack.

This task requires two people.

To mount the switch in the rack:

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

2. Verify that the mounting brackets and chassis rails have been securely attached to the switch chassis.

3. Verify that the slide rails have been correctly attached to the rear rack posts.

4. Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails.

5. One person performs the following operations:

a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack posts.

b. Pushes the switch slowly for the slide rails to slide into the chassis rails smoothly until the mounting brackets are flush against the front rack posts.

- For long slide rails of rack mounting rail kit A and slide rails of rack mounting rail kit C, make sure the front ends of the slide rails reach out of the chassis rails.

- For super-short slide rails of rack mounting rail kit B, make sure the slide rails slide a minimum length of 90 mm (3.54 in) into the chassis rails.

6. The other person uses screws (user-supplied, rust-proofed) to attach the mounting brackets to the rack.

Grounding the switch by using a grounding strip

CAUTION:

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

· Do not connect the grounding cable 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.

· 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 so the faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the switch.

To ground the switch by using a grounding strip:

1. Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the switch chassis. For more information, see "Connecting the grounding cable to the chassis."

2. Remove the hex nut of a grounding post on the grounding strip.

3. Attach the ring terminal at the other end of the grounding cable to the grounding post on the grounding strip, and secure the ring terminal to the grounding post with the hex nut.

You can access the switch from the serial console port or the mini USB console port. As a best practice, use the serial console port to access the switch (the switch is provided with a serial console cable). To access the switch from the mini USB console port, prepare a mini USB console cable yourself.

In the following figure, the switch is connected to a PC from the serial console port.

Figure3-1 Connecting the switch to a terminal from the serial console port

Connecting the serial console cable

A serial console cable is an 8-core cable, with a crimped RJ-45 connector at one end for connecting to the serial console port of the switch, and a DB-9 female connector at the other end for connecting to the serial port on the console terminal.

Figure3-2 Serial console cable

Table3-1 Serial console cable pinout

RJ-45	Signal	DB-9	Signal
1	RTS	8	CTS
2	DTR	6	DSR
3	TXD	2	RXD
4	SG	5	SG
5	SG	5	SG
6	RXD	3	TXD
7	DSR	4	DTR
8	CTS	7	RTS

To connect the switch to a terminal (for example, a PC) by using the serial console cable:

1. Plug the DB-9 female connector of the serial console cable to the serial port of the PC.

2. Connect the RJ-45 connector to the serial console port of the switch.

NOTE:

· Identify the mark on the console port and make sure you are connecting to the correct port.

· The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end.

Connecting a mini USB console cable

A USB mini console cable has a USB mini-Type B connector at one end to connect to the Mini USB console port of the switch, and a standard USB Type A connector at the other end to connect to the USB port on the configuration terminal.

To connect the switch to a configuration terminal by using a USB mini console cable:

1. Connect the standard USB Type A connector to the USB port on the configuration terminal.

2. Connect the USB mini Type B connector to the Mini USB console port on the switch.

3. Click http://www.h3c.com/en/home/USB_Console/, or copy it to the address bar on the browser to log in to download page of the USB console driver, and download the driver.

4. Select a driver program according to the operating system you use:

¡ XR21V1410_XR21B1411_Windows_Ver1840_x86_Installer.EXE—32-bit operating system.

¡ XR21V1410_XR21B1411_Windows_Ver1840_x64_Installer.EXE—64-bit operating system.

5. Click Next on the installation wizard.

Figure3-5 Completing the device driver installation wizard

Setting terminal parameters

To configure and manage the switch through the serial console port or mini USB console port, you must run a terminal emulator program, TeraTermPro or PuTTY, on your configuration terminal. 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—9600.

· Data bits—8.

· Stop bits—1.

· Parity—None.

· Flow control—None.

Starting the switch

1. Before powering on the switch, verify that the following requirements are met:

¡ The power cords are correctly connected.

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

¡ The console cable is correctly connected.

¡ The configuration terminal (a PC, for example) has started, and the parameters are set correctly.

2. 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 vary by software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device.

3. After the startup completes, you can access the CLI to configure the switch.

For more information about the configuration commands and CLI, see H3C S6805&S6850&S9850 Switch Series Configuration Guides and H3C S6805&S6850&S9850 Switch Series Command References.

4 Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S6805 switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

The switch can set up an IRF fabric only with switches from the same switch series.

IRF fabric setup flowchart

Figure4-1 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."
3. Connect ground wires and power cords.	See "Grounding the switch by using a grounding strip" and "Connecting the power cord."
4. Power on the switches.	N/A
5. Configure basic IRF settings.	See IRF configuration in H3C S6805&S6850&S9850 Switch Series Virtual Technologies Configuration Guide.
6. Connect the physical IRF ports.	Connect the physical IRF ports on switches by using QSFP28 transceiver modules and fibers, QSFP28 fiber cables, QSFP 28 copper cables, QSFP+ transceiver modules and fibers, QSFP+ fiber cables, or QSFP+ copper cables. 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 top-of-rack (ToR) access solution for a data center.

As your business grows, you can add member switches into the IRF fabric to increase the switching capacity without any topology change or replacement.

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 command line interface of the master switch.

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 IRF configuration in H3C S6805&S6850&S9850 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 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, 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 at least 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 IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure4-2 IRF fabric in daisy chain topology

Figure4-3 IRF fabric in ring topology

You can set up 100/40-GE IRF physical connections by connecting only QSFP28 ports between S6805 switches.

You can bind several ports to an IRF port for increased bandwidth and availability.

Identifying physical IRF ports on the member switches

Identify the QSFP28 ports for IRF connections on the member switches according to your topology and connection scheme.

All the QSFP28 ports on the switch can be used for IRF connections.

Planning the cabling scheme

You can use only QSFP28 transceiver modules and optical fibers, QSFP28 fiber cables, QSFP28 copper cables, QSFP transceiver modules and optical fibers, QSFP fiber cables, or QSFP copper cables to connect the switches for IRF connections.

If the IRF member switches are far away from one another, choose QSFP+/QSFP28 transceiver modules and optical fibers. If the IRF member switches are all in one equipment room, use QSFP/QSFP28 copper or fiber cables. For more information about transceiver modules and cables available for the switch, see "Appendix C Ports and LEDs."

The following subsections describe several H3C recommended IRF connection schemes by using QSFP28 transceiver modules and optical fibers, QSFP28 copper cables, and QSFP28 fiber cables. All these schemes use a ring topology.

Connecting the IRF member switches in one rack

Figure4-4 shows an example for connecting four IRF member switches in a rack. The switches in the ring topology (see Figure4-5) are in the same order as connected in the rack.

Figure4-4 Connecting the switches in one rack

Figure4-5 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.

Figure4-6 shows an example for connecting four top of rack IRF member switches by using QSFP28 cables and QSFP28 transceiver modules and optical fibers. The topology is the same as Figure4-5.

Figure4-6 ToR cabling

Configuring basic IRF settings

After you install the IRF member switches, power on the switches and then log in to each IRF member switch to configure basic IRF settings, including their member IDs, member priorities, and IRF port bindings.

For the approaches to accessing the switch, see login management in H3C S6805&S6850&S9850 Switch Series Fundamentals Configuration Guide.

For information about configuring IRF settings, see IRF configuration in H3C S6805&S6850&S9850 Switch Series Virtual Technologies Configuration Guide,.

Connecting the physical IRF ports

CAUTION:

Wear an ESD wrist strap when you connect fiber or copper cables or transceiver modules and optical fibers. For more information, see the installation guide for the transceiver modules and cables.

Use fiber or copper cables or transceiver modules and optical fibers to connect the IRF member switches as planned.

Accessing the IRF fabric to verify the configuration

To verify the basic functionality of the IRF fabric:

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 or SNMP to access the IRF fabric from the network management station. For more information about the accessing method, see login management in H3C S6805&S6850&S9850 Switch Series Fundamentals Configuration Guide.

4. Display the running status of the IRF fabric by using the commands in Table4-1.

Table4-1 Displaying and maintaining IRF configuration and running status

Task	Command
Display information about the IRF fabric.	display irf
Display all members' IRF configurations.	display irf configuration
Display IRF fabric topology information.	display irf topology

NOTE:

To avoid IP address collision and network issues, configure at least 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 H3C S6805&S6850&S9850 Switch Series Virtual Technologies Configuration Guide.

To avoid interference between cables, layer cables as follows:

· Use category-6A or above cables and connectors.

· 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 are 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, port 2 on the device to port 3 on the distribution frame, and port 3 on the device to port 5 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, port 2 on the device to port 1 on distribution frame 2, and port 3 on the device to port 2 on distribution frame 1.
