1.1 Installation Procedure
Installing a Switch
Post-Installation Checks
1.2 Installation Preparation
Confirm the following before installation:
•The installation site provides sufficient space for heat dissipation.
•The installation site meets the temperature and humidity requirements of the switch.
•The power supply and required current are available in the installation site.
•The Ethernet cables have been deployed in the installation site.
1.2.1 Checking the Installation Site
Item
Requirement
Cleanliness
The device must be installed in a clean, dry, and well ventilated standard equipment room with controllable
temperature.
Dust proofing
Dustproof measures must be taken in the site. Dust will cause electrostatic discharges on the chassis and
affect connections of metal connectors and joints. This shortens service life of the device and may cause
failures of the device.
Temperature and
humidity
The equipment room must be free from leaking or dripping water, heavy dew, and damp. The temperature
and humidity in the installation site must be within specifications. For the operating temperature and
relative humidity ranges required by the device, see the device specifications. If the relative humidity
exceeds 70%, using dehumidifiers or dehumidifying air conditioners is recommended.
Corrosive gases
avoidance
The installation site must be free from acidic, alkaline, or corrosive gases.

1.2.2 Mounting the Cabinet or Rack
When mounting the cabinet, please note the following:
•All expansion bolts for fastening the cabinet base to the ground should be installed and tightened in
sequence from bottom to up (large flat washer, spring washer, and nut), and the installation holes on
the base and the expansion bolts are aligned.
•The installed cabinet is not movable after installation.
•The installed cabinet is vertical to the ground.
•When multiple cabinets are placed side by side in the equipment room, they should be aligned with
each other, leaving an error less than 5mm (0.20 in.) .
•The front and rear doors of the cabinet should be installed to allow you open and close them
smoothly. The locks should work normally, and all keys should be complete.
•There should be no unnecessary and informal labels inside the cabinet and on service modules.
•Filler panels are installed in empty slots.
•The screws in the cabinet should be fastened tightly and be of the same model.
•The switch is securely installed, and the screws on the panel should be fastened tightly.
•All wiring outlets at the top and bottom of the cabinet should be installed with rodent-resistant nets
with openings of no more than 15mm (0.59 in.) in diameter to prevent rodents and other small
animals from entering the cabinet.
•An anti-static wrist strap should be provided in the cabinet.
Procedure :
1. Plan the available space before installing the cabinet. Maintain a clearance before the front and back
doors for maintenance and operation.
2. Install and fasten the cabinet in the specified site as planned.
3. Install the cable troughs and cables.
4. Install the trays and cable management brackets on the rack according to the number of switches
installed into the cabinet.
1.2.3 Checking the Power Conditions
•Before use, please check whether there is obvious damage to the power supply shell and whether the
power supply is defective such as abnormal noise.

Switch Hardware Installation and Maintenance Guide
•The device is only allowed to be plugged into the power module that accompanies the device, otherwise it
may lead to unknown risks.
•Power module in 1+1 backup can be hot-swapped one of them, need to ensure that the other power
module on the equipment is in the power supply state when replaced, otherwise unplugging the power
module will cause the switch to lose power, resulting in business interruption.
•Prohibit the mixed use of power modules with different power and different cooling methods.
1.2.4 Preparing Installation Tools and Accessories
Common Tools
Phillips screwdriver, Ethernet and optical cables, cage nuts, diagonal pliers and cable ties
Special Tools
Anti-static gloves, wire stripper, crimping plier, RJ45 connector crimping plier, and wire cutter
Meters
Multimeter, bit error rate tester (BERT), and optical power meter
•The S3270 series switch is delivered without a tool kit. You need to prepare a tool kit by yourself.
1.3 Installing a Switch
Precautions :
Please confirm the following before installing the switch:
•Connect the power cords of different colors to the corresponding blinding posts.
•Ensure that the connector of the power cord and the power port of the device are in good contact. After
the power cord is securely inserted into the device, fasten the power cord with power cord retention clips.
•Do not place anything on the S3270 series switches.
•Maintain sufficient ventilation space(more than 10 cm/3.94 in.) around the device to ensure good air
circulation.Do not stack the device.
•Keep the S3270 series switch away from high-power radio launch pads,and high-frequency large-current
devices; Take electromagnetic shielding measures to minimize interference when necessary, for example,
use shielded interface cables.

•The switch is prepared and transported to a location close to the cabinet.Route the 100-meter(328.08 ft)
Ethernet cable only indoors. Take lightning protection measures if they need to be routed outdoors.
1.3.1 Mounting the Switch in a Cabinet or Rack
The S3270 series switch meets the EIA standard size and can be installed in a 19-inch wiring closet
with the following installation procedure:
1: Remove the screws (packaged with the lugs) and install one end of the lugs to the switch as
shown below:

Mounting the Switch in a Rack：
Step 2: As shown in the figure below, place the switch horizontally in the appropriate position in
the cabinet, and fix the other end of the lugs to the front hole bar of the cabinet through the M6
screws and the matching floating nuts, and the installation is completed as shown in the figure
below:

1.3.2 Mounting the Switch on a Workbench
In most cases, users do not have a standard 19-inch rack. Therefore, the most common method is to place the
switch on a clean workbench. This operation is relatively simple, and the specific installation process is as
follows:
Step 1: Stick the 4 adhesive pads provided in the box in the pits at the corners of the bottom of the switch, as
shown in the following figure:
Step 2: Place the switch flat on the desktop to ensure good airflow ventilation around the switch as shown in
the diagram below.

1.4 Connecting a Switch
1.4.1 Connecting the Grounding Cable
The grounding point with a protective earth on the back of the S3270 series mainframe should be connected
first to the cabinet's grounding terminal, and then the cabinet's grounding terminal is connected to the
grounding row in the equipment room.
Precautions:
•The sectional area of the grounding wire should be determined according to the possible maximum current.
Cables of good conductors should be used.
•Do not have bare wires exposed.
•Grounding resistance: Less than 1Ω .
•To guarantee the security of the person and the equipment, the switch must be grounded properly.
The grounding resistance between the chassis and the ground should be less than 1Ω.
•The maintenance personnel should check whether the AC socket is reliably connected to the
protective ground of the building. If not, the maintenance personnel should use a protective ground
conductor from the AC outlet protective ground terminal to the building protective ground.
•The power socket should be installed near the equipment and easily accessible.
•When installing the switch, connect the grounding first and disconnect it last.
•The cross-sectional area of the protection ground wire should be at least 2.5mm2(12AWG) .
1.4.2 Connecting Power Cables
There is one ground terminal on the back of the S3270 series switch chassis, which should be connected to
the grounding lug of the rack first, and then connect the grounding lug to the grounding bar of the equipment
room.
Precautions:
.To avoid electric shock, do not connect the power cable while the power is on.
.Before connecting cables, take ESD protection measures, for example, wear ESD gloves or an ESD wrist
strap.
.Power cables must be buried underground or routed indoors and cannot be led into the equipment room
aerially.
.Do not power on a switch before you finish installing the switch and connecting cables.
Procedure :
1. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact
with your wrist.
