•
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.
•
Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Make sure the power source voltage is as required.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
To avoid ESD damage, wear an ESD wrist strap to hot-swap a power supply.
Examining the installation environment
To ensure correct operation of your switch, make sure the installation environment meets the
requirements listed in Table1-2.

1-2
Table1-2 Checking list for the installation environment
Item Requirements
Ventilation and heat dissipation
CAUTION:
To ensure correct operation of your device, make sure the installation
environment is adequately ventilated to prevent the switch from
overheating.
•Ensure a minimum clearance of 10 cm (3.94 in) around the chassis.
•Do not install the device near a heat source, for example, a stove or
heater.
•Ensure air ventilation in the installation environment.
•Do not block the ventilation holes in the device or power adapter.
Anti-moisture
CAUTION:
Water or moisture might damage the circuits of the device.
•Do not place the device near water or in a damp environment.
•Install the switch in a clean, dry, and ventilated place where
temperature is controlled in a stable range.
•Make sure the installation environment is free from water leakage or
condensation. If required, install a dehumidification device (such as
an air conditioner with a dehumidification function or a dedicated
dehumidifier).
•Do not operate the device under or near the water source, such as
the wash basin, laundry room, or areas with high humidity.
•Do not touch the device with wet hands.
Hot surface
Hot surface. Use caution when working near the hotsurface. If the switch
has a hot surface sign , the switch is intended for installation in a
restricted access area. A restricted access area can be accessed by
skilled, instructed, or qualified personnel.
Temperature/humidity
For correct operation and long service life of your switch, maintain the
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 issues 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 the switch, see
technical specifications in FS5100-EI Switch Series Hardware
Information and Specifications.
Lightning protection
CAUTION:
Ground the switch correctly and verify the grounding. For more
information, see "Grounding the switch."
•If you ground the switch by using a grounding strip, make sure the
grounding resistance of the grounding strip in the equipment roomis
less than 1Ω.
•If you ground the switch by using a grounding conductor buried in
the earth ground, make sure the grounding resistance of the
grounding conductor in the ground is less than 10Ω.
•Route the signal cables along indoor walls, bury the cables in the
earth ground, or thread the cables through steel tubes. Install a

1-3
Item Requirements
signal lightning arrester with a nominal discharge current for a
corresponding network interface.
•Keep the signal cables far from power cords and lightning rod down
conductors.
•As a best practice, route power cords indoors. If anAC power cord
is routed from outdoors, connect theAC power cord first to a power
lightning arrester before leading it to theAC power port on the
switch. Make sure the power lightning arrester has a nominal
discharge current and the total length of the power cord from the
power lighting arrester to the power port on the switch is less than 5
m (16.40 ft).
•
Ground the switch, rack, independent power supplies, and lightning
arresters separately.
•You must ground optical fibers with reinforcing metal stiffener from
outdoors on an optical distribution frame (ODF) or fiber splice
enclosure.
Cable routing
CAUTION:
Do not run an Ethernet cable and power cord in parallel.
•Route different types of cables separately.
•Keep power cords a minimum of 5 cm (1.97 in) away from other
cables.
ESD prevention
•Ground the switch correctly.
•To avoid ESD damage to the device or components, always wear an
ESD wrist strap when you install or remove the device or
components.
•Make sure the wrist strap has good skin contact and is reliably
grounded.
Cleanliness •For more information, see "Cleanliness."
Corrosive gas prevention The installation site must be free from corrosive gases such as acid gases and alkaline gases. For more information, see "Corrosive gas
limit."
EMI
•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 device far away from radio transmitting stations, radar
stations, and high-frequency devices.
•Use electromagnetic shielding, for example, shielded interface
cables, when necessary.
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. Table1-3 describes the switch requirement for
cleanliness.
Table1-3 Switch requirement for cleanliness
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 1.8 × 107particles/m3

1-4
•
Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the
equipment room.
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
Use screen doors and window screens for doors and windows open to the outside and make
sure the external windows are air tight.
•
Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does
not produce powders.
•
Clean the equipment room regularly and clean the air filters of the rack each month.
•
Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD
clothing and shoe covers clean, and change them frequently.

2. Make sure the front mounting brackets and shoulder screws are securely attached to the two
sides of the switch.
3. Attach cage nuts to the front rack posts. Make sure the corresponding cage nuts on the left and
right front rack posts are at the same height.
4. One person supports the chassis bottom with one hand, holds the front part of the chassis with
the other, and pushes the chassis into the rack gently. Make sure the shoulder screws rest
firmly on the upper edge of the rear mounting brackets. See Figure2-11 and Figure2-12.
5. The other person attaches the front mounting brackets by using M6 screws and cage nuts to the
front rack posts. Make sure the switch is installed securely in the rack. See Figure2-11 and
Figure2-12. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.

Mounting the switch on a workbench
IMPORTANT:
•
Ensure 10 cm (3.9 in) of clearance around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
If a standard 19-inch rack is not available, you can place you switch on a workbench.
To mount the switch on a workbench:
1. Verify that the workbench is sturdy and reliably grounded.
2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
3. Attach the rubber feet to the four round holes in the chassis bottom.
4. Place the switch with upside up on the workbench.
Mounting the switch on a wall
CAUTION:
•
Before drilling holes in a wall, make sure no electrical lines exist in the wall.
•Leave a minimum clearance of 10 mm (0.39 in) around the chassis for heat dissipation.
Table2-5 describes the switch models that support wall mounting and installation holes distances
required for wall-mounting the switch.

To mount the switch on a wall:
1. Mark two installation holes on the wall. Make sure the two holes are on the same horizontal line.
See Table2-5 for the distance requirement between the two holes.
Figure2-14 Installing the switch on a wall (1)
2. Drill two holes with a diameter of 6 mm (0.24 in) and a depth of 25 mm (0.98 in) at the marked
locations. Hammer the screw anchors into the wall and use a Phillips screwdriver to fasten the
screw into the screw anchor. Leave 1.5 mm (0.06 in) between the screw head and the wall for
hanging the switch.
