4 Site Environment
Do not place this product in an environment with flammable or explosive gases, or smoke.
The installation site must be free from leaking or dripping water, heavy dew, and humidity. If the relative
humidity is high, use dehumidifiers or dehumidifying air conditioners.
The installation site must be well ventilated. Ensure that air vents on the equipment are not blocked.
Do not install the equipment in a dusty environment.
Leave at least 50 mm clearance at the rear and both sides of the chassis for heat dissipation.
S series switches use forced, intelligent, or natural heat dissipation mode. If multiple switches are installed in a
cabinet/rack, leave at least 1 U (44.45 mm) distance between each two switches. This distance is
recommended for switches using forced or intelligent heat dissipation, and is required for switches using
natural heat dissipation.
Ensure that the temperature and humidity at the installation site meet the switch operation requirements. For
the specific requirements, see the Hardware Description for your switch on the Huawei support website.
Ethernet cables used outdoors must be buried underground or routed through steel pipes to protect the
switch from lightening. Do not route Ethernet cables overhead.
To protect network ports from lightning, use 8-line surge protectors or Huawei certified 4-line surge
protectors. When installing a network port surge protector, connect the IN ports to network devices and
connect the OUT ports to network ports of the switch.
5 Installing the Chassis
Scenario 1: Desk Mounting
S5710-HI and S6700-EI series switches cannot be desk mounted.

Step 4
When a chassis uses Category-6 or higher Ethernet cables, the distance between the port side and interior side
of the cabinet door must be larger than or equal to 120 mm.
Switches cannot be installed in a 600 mm deep cabinet when they are equipped with 1150 W PoE power
modules.
To install a 250 mm wide switch in a 19-inch cabinet, purchase long mounting brackets.
For the 220 mm deep models of the S2700 and S3700 series, and the S5700-24TP-SI-AC/DC, each mounting
bracket needs to be fixed on the chassis with only two screws. For other switch models, each mounting
bracket needs to be fixed with three screws.
When more than one switch is installed in a cabinet/rack, leave at least 1 U distance between them.
The captive screws and M6 screws are not delivered with the switch and need to be separately purchased if
needed.
Scenario 4: Cabinet/Rack Mounting
S series Ethernet switches can be installed in a 19-inch standard cabinet/rack. Cabinets purchased from other
vendors must have enough space for equipment installation.
If the distance between front and rear mounting rails is not within the required range, install guide rails or a
tray in the cabinet/rack to support the chassis. Guide rails or trays are not delivered with the product and must
be purchased separately.
Before You Start
