Preparing for installation
The H3C S6820 Switch Series includes the following models:
•
S6820-32H.
•
S6820-56HF.
•
S6820-4C.
Safety recommendations
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 field replaceable units (FRUs), including power modules 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
neighboring devices 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.
1
•
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 for the switch, 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 Dust concentration limit in the equipment room
Substance
Concentration limit (particles/m³)
Dust
≤ 3 × 10 (no visible dust on the tabletop over three days)
4
NOTE:
Dust diameter ≥ 5 μm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 2.

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.
2
Laser safety
WARNING!
• The switch is a Class 1 laser device.
• Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
•
Phillips screwdriver.
•
ESD wrist strap.
•
Marker.
3
Installing the switch
CAUTION:
Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open
the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence
caused thereby.

Figure 22 Attaching the mounting brackets and chassis rails to the S6820-4C switch
(network port-side mounting position for the mounting brackets)
NOTE:
Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left panel of the
chassis. If you use one of these grounding points, you must connect the grounding cable to the
grounding point before you mount the switch in the rack.
As a best practice, use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
To use auxiliary grounding point 2 on the S6820-4C switch, prepare a grounding cable yourself.
This section uses the primary grounding point on the S6820-32H switch as an example.
To connect the grounding cable to a grounding point:
1.
Choose a grounding point as required.
This example uses the primary grounding point.
2.
Unpack the grounding cable and grounding screws.
3.
Use two grounding screws to attach the two-hole grounding lug of the grounding cable to the
grounding holes at the grounding point. Use a screwdriver to tighten the screws. See Figure 23.
14
Figure 23 Attaching the grounding cable to the primary grounding point on the S6820-32H
switch
Attaching the slide rails to the rack
The procedure is the same for attaching 1U and 2U slide rails to the rack. This section uses the 1U
slide rails as an example.
To attach the slide rails to the rack:
1.
Identify the slide rail installation position in the rack.
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 use screws
(user-supplied) to attach the slide rail to the post, as shown in Figure 24.
4.
Repeat the preceding steps to attach the other slide rail to the other rear rack post.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
Figure 24 Installing the 1U slide rails
15
Mounting the switch in the 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 to slide the chassis rails along the slide rails until the mounting
brackets are flush with the rack posts.
6.
Another person uses screws (user-supplied) to attach the mounting brackets to the rack.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the
chassis rails.
The rack-mounting procedures are the same for the S6820-56HF and S6820-32H switches. The
following figures use the S6820-32H switch as an example.
Figure 25 Mounting the S6820-32H switch in the rack (power module-side mounting position
for the mounting brackets)

17
Figure 28 Mounting the S6820-4C switch in the rack (Port-side mounting position for the
mounting brackets)
NOTE:
To rack-mount the S6820-4C switch by using 2U high mounting brackets and slide rails, use two
screws and two cage nuts to attach each mounting bracket to the rack. Determine the screw
installation positions based on the distances between the square holes on the rack posts. The screw
installation positions in Figure 27 and Figure 28 are for illustration only.
Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
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.
You can ground a switch by using a grounding strip at the installation site or the AC power cord
connected to the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch with a grounding strip
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
18
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
To connect the grounding cable:
1.
Attach the two-hole grounding lug of the grounding cable to a grounding point on the 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 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.

Grounding the switch by using the AC power cord
If the installation site does not have grounding strips, you can ground an AC-powered switch through
the protective earth (PE) wire of the power cord. Make sure the following requirements are met:
•
The power cord has a PE terminal.
•
The ground contact in the power outlet is securely connected to the ground in the power
distribution room or on the AC transformer side.
•
The power cord is securely connected to the power outlet.
NOTE:
If the ground contact in the power outlet is not connected to the ground, report the problem and
reconstruct the grounding system.

NOTE:
As a best practice to guarantee the grounding effect, use the grounding cable provided with the
switch to connect to the grounding strip in the equipment room.
Installing/removing fan trays
CAUTION:
The switch has multiple fan tray slots. To ensure good ventilation of the switch, follow these
guidelines to install and remove fan trays:
• The switch is provided with the fan tray slots empty. Before powering on the switch, make sure all
fan tray slots have fan trays installed and the fan trays are the same model.
• Make sure all slots have a module or filler panel installed when the switch is operating.
• If multiple fan trays fail on an operating S6820-32H or S6820-56HF switch, do not remove the fan
trays at the same time. Replace the fan trays one after another and finish replacing a fan tray
within 3 minutes.
• If a fan tray fails on an operating S6820-4C switch, replace the fan tray immediately and keep the
failed fan tray in position before replacement. If two fan trays fail, finish replacing the fan trays
within 1 minute.
The installation and removal procedures are the same for the LSWM1FANSA, LSWM1FANSAB,
LSWM1BFANSC, and LSWM1BFANSCB fan trays. The following installation and removal
procedures use the LSWM1FANSA fan tray as an example.
20
Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, 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.
IMPORTANT:
Before powering on the switch, make sure the fan tray airflow direction and the preferred airflow
direction of the switch are the same. If they are not the same, the system generates traps and logs.
You can use the fan prefer-direction command to configure the preferred airflow direction for the
switch. By default, the preferred airflow direction of the switch is from the port side to the power
module side.
For more information about the fan prefer-direction command, see H3C S6820 Switch Series
Fundamentals Command Reference.
Select fan trays for the switch as needed. For the available fan trays and their specifications, see
"Fan trays."
To install a fan tray:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the fan tray and verify that the fan tray model is correct.
3.
Orient the fan tray with the "TOP" mark on top. Grasp the handle of the fan tray with one hand
and support the fan tray bottom with the other, and slide the fan tray along the guide rails into
the slot until the fan tray is fully seated in the slot and has a firm contact with the backplane.
See Figure 31.

Installing/removing power modules
WARNING!
• To avoid bodily injury and device damage, strictly follow the procedures in Figure 33 and Figure
34 to install and remove a power module.
• Provide a separate circuit breaker for each power module.
The S6820-32H and S6820-56HF switches each have two power module slots. The S6820-4C
switch has four power module slots. The S6820-32H and S6820-56HF switches come with one
power module slot empty and one installed with a filler panel. The S6820-4C switch comes with two
power module slots empty and two installed with filler panels. You can install power modules for the
switch as required.
For information about the available power modules, see "Appendix B FRUs."

Figure 34 Removal procedure
Installing a power module
CAUTION:
• Follow the forward inertia of the power module when inserting it into the chassis, and make sure
the power module has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power module gently. If
you encounter a hard resistance while inserting the power module, pull out the power module
and insert it again.
22
The LSVM1AC650 and LSVM1DC650 installation procedure is the same on the S6820 switches.
The figures in this section use the S6820-32H switch as an example.
To install a power module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Remove the filler panel, if any, from the target power module slot, as shown in Figure 35.
Figure 35 Removing a filler panel
3.
Unpack the power module and verify that the power module model is correct.
4.
Correctly orient the power module with the words on the power module upward. Grasp the
handle of the power module with one hand and support its bottom with the other, and slide the
power module slowly along the guide rails into the slot.
The slot is foolproof. If you cannot insert the power module into the slot, re-orient the power
module rather than use excessive force to push it in.
Figure 36 Installing a power module (LSVM1AC650)
Removing a power module
CAUTION:
• When an S6820-32H or S6820-56HF switch has two power modules in 1+1 redundancy mode,
removing one power module does not affect the operation of the switch. When the switch has
only one power module installed, removing the power module powers off the switch.
• When an S6820-4C switch has power modules in 2+1 or 2+2 redundancy mode, removing one or
two power modules does not affect the operation of the switch. When the switch has only two
power modules installed, removing power modules powers off the switch or causes power
insufficiency.

Accessing the switch for the first time
Setting up the configuration environment
You can access the switch through the serial console port or the mini USB console port. As a best
practice, use the serial console port to access the switch. To access the switch through the mini USB
console port, you need to prepare a mini USB console cable yourself.
The example uses a console cable to connect a console terminal (PC) to the serial console port on
the switch.
Figure 45 Connecting the serial console port to a terminal
Connecting the 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

Setting up an IRF fabric
You can use H3C IRF technology to connect and virtualize multiple S6820 switches into a large
virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability,
and manageability.
IRF fabric setup flowchart
Figure 50 IRF fabric setup flowchart
To set up an IRF fabric:
Step
1.
Plan IRF fabric setup.
Description
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
34
Step
Description
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" and "Connecting the power cord."
4.
Power on the switches.
N/A
5.
Configure basic IRF settings.
See H3C S6820 Switch Series IRF Configuration Guide.
Connect the physical IRF ports.
Connect the physical IRF ports on switches. Use
QSFP28/QSFP+/SFP28 transceiver modules and fibers for
connections over long distances. Use QSFP28/QSFP28 to
SFP28/QSFP+/SFP28 cables for connections over short distances.
6.
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
Determine 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 H3C S6820 Switch Series 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.
35
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 IRF port connections in the two figures are for illustration only, and more connection methods
are available.

You can set up IRF links between S6820 switches as follows:
•
Use a QSFP28 module and fiber or a QSFP28 cable to connect QSFP28 ports for a 100-GE
IRF physical connection.
•
Use a QSFP+ module and fiber or a QSFP+ cable to connect QSFP28 ports for a 40-GE IRF
physical connection.
•
Use a 100G QSFP28 to 4 × 25G SFP28 cable to connect a QSFP28 port to four 25G SFP28
ports.
•
Use a QSFP+ module and fiber or a QSFP+ cable to connect QSFP+ ports for a 40-GE IRF
connection.
•
Use an SFP28 module and fiber or an SFP28 cable to connect SFP28 ports for a 25-GE IRF
connection.
You can bind several ports to an IRF port for increased bandwidth and availability.
Identifying physical IRF ports on the member switches
Identify the physical ports for IRF connections on the member switches according to your topology
and connection scheme.
All the QSFP28, QSFP+, and SFP28 ports on the switch can be used for IRF connections, except for
QSFP28 ports on the LSWM18CQMSEC interface module.
When you select ports in a port group for IRF links, you must use all or none of the ports in the group
for IRF links. The ports can be bound to different IRF ports.
The port grouping rules are as follows:
•
The S6820-56HF switch has two port ranges. Ports numbered 1 to 24 are in one range and
ports numbered 33 to 56 are in the other range. In each range, the ports are grouped by port
number in order, starting from the lowest number. Each group contains four ports.
•
On an LSWM124TG2H module, the ports numbered 1 to 24 are grouped by port number in
order, starting from the lowest number. Each group contains four ports.
•
On an LSWM116Q module, the ports are grouped by port number in order, starting from 1. Each
group contains two ports.
•
The four 25-GE breakout interfaces of a 100-GE port are in one port group. To split a 100-GE
port, use the using twenty-fivegige command.
•
Except the LSWM116Q module, if you use a 40-GE or 100-GE port that is not split for IRF links,
no grouping restrictions exist.
Planning the cabling scheme
You can use QSFP28/QSFP28 to SFP28/QSFP+/SFP28 cables, or QSFP28/QSFP+/SFP28
transceiver modules and fibers to connect the S6820 switches for IRF connections.
If the switches are all in one equipment room, choose QSFP28/QSFP28 to SFP28/QSFP+/SFP28
cables for IRF connections. If the switches are far away from one another, choose
QSFP28/QSFP+/SFP28 transceiver modules and fibers for IRF connections.
For more information about available cables, see "Appendix C Ports and LEDs."
The following subsections describe several IRF connection schemes by using the QSFP28 cables
and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF
connections.
Connecting the IRF member switches in one rack
Figure 53 shows an example for connecting four IRF member switches in a rack. The switches in the
ring topology (see Figure 54) are in the same order as connected in the rack.

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 55 shows an example for connecting four top of rack IRF member switches. The topology is
the same as Figure 54.

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 S6820 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.
•
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S6820 Switch Series IRF
Configuration Guide.
Connecting the physical IRF ports
CAUTION:
Wear an ESD wrist strap when you install transceiver modules, fibers, and cables. For more
information, see the installation guide.
Use transceiver modules and fibers or cables 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 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 or SNMP to access the IRF fabric from the network management station. (See H3C
S6820 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 6.

NOTE:
To avoid IP address collision and network problems, 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 S6820 Switch Series IRF Configuration Guide.
