Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury, 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 replacing 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 make sure:
•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 bring 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.

2
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.
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:
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.
Table 2 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
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.
Laser safety
WARNING!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.

3
The switch is a Class 1 laser device.
Installation tools
The installation tools are not provided with the switch. Prepare them yourself.
•Phillips screwdriver.
•ESD wrist strap.
•Marker.

Attaching the mounting brackets and chassis rails to the chassis
1. Align the mounting brackets with the screw holes in the rear mounting position (see Figure 8) or
front mounting position (see Figure 9).
2. Use M4 screws (provided) to attach the mounting brackets to the chassis.
3. Align the chassis rails with the rail mounting holes in the chassis:
{If the mounting brackets are in the rear mounting position, align the chassis rails with the
screw holes at the front of the side panels (see Figure 8).
{If the mounting brackets are in the front mounting position, align the chassis rails with the
screw holes at the rear of the side panels (see Figure 9).
4. Use M4 screws (provided) to attach the chassis rails to the chassis.
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:
Select the grounding point as required. The primary grounding point and auxiliary grounding point 1
are located on the left side panel. 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.
To connect the grounding cable to a chassis grounding point, for example, the primary grounding
point:
1. Choose a grounding point.
2. Unpack the grounding cable and grounding screws.
3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the
grounding point, insert the grounding screws into the holes, and tighten the screws with a
screwdriver to attach the grounding lug to the chassis, as shown in Figure 8.

Figure 8 Attaching the rear mounting brackets/chassis rails/grounding cable to the chassis
Figure 9 Attaching the front mounting brackets/chassis rails to the chassis
NOTE:
•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 S5820V2-48S, S5820V2-52QF, S5820V2-52QF-U,
S5820V2-52Q, or S5820V2-54QS-GE switch, prepare a grounding cable yourself.
Attaching the slide rails to the rack
1. Identify the rack attachment position for the slide rails.
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.

10
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user supplied) to attach the slide rail to the rack, as shown in Figure 10.
4. Repeat the preceding step to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
Figure 10 Installing the slide rails
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 supports the bottom of the switch, aligns the chassis rails with the slide rails on the
rack posts, and then slides the chassis rails slowly 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.

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

12
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.
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 at one end of the grounding cable to a grounding point on the
switch chassis (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 strip through
the grounding post, and fasten the ring terminal with the removed hex nut.

NOTE:
•As a best practice, use the primary grounding point or auxiliary grounding point 1, because the
grounding cable and grounding screw provided with the switch are applicable only to these two
grounding points.
•To use auxiliary grounding point 2 on the S5820V2-48S/S5820V2-52QF, S5820V2-52QF-U,
S5820V2-52Q, or S5820V2-54QS-GE switch, prepare a grounding cable yourself. The
connection method is the same as connecting to the other two grounding points.
Grounding the switch by using the AC power cord
If the installation site does not have any grounding strips, you can ground an AC-powered switch
through the protective earth (PE) wire of the power cord, but must make sure:
•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:
To guarantee the grounding effect, use the grounding cable provided with the switch to connect to
the grounding strip in the equipment room as long as possible.
