•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.
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 Intelbras SC 3570 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 room is
less than 1
•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 10.
•Route the signal cables along indoor walls, bury the cables in the
earth ground, or thread the cables through steel tubes. Install a
signal lightning arrester with a nominal discharge current for a

3
Item
Requirements
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 an AC power cord
is routed from outdoors, connect the AC power cord first to a power
lightning arrester before leading it to the AC 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 FRUs, always wear an ESD
wrist strap when you install or remove the device or FRUs.
•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

Grounding the switch by using a grounding conductor buried
in the earth ground
If the installation site does not have grounding strips, but earth ground is available, hammer a 0.5 m
(1.64 ft) or longer angle iron or steel tube into the earth ground to act as a grounding conductor.

The dimensions of the angle iron must be a minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The
steel tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion
protection.

Verifying the connection after grounding the switch
•If you ground the switch by using a grounding strip, perform the following tasks:
a. Use a multimeter to measure the resistance between the switch grounding terminal and
grounding point, and make sure the resistance is less than 0.1
b. Use a grounding resistance tester to measure the grounding resistance of the grounding
strip, and make sure the grounding resistance is less than 1
•If you ground the switch by using a grounding conductor buried in the earth ground, perform the
following tasks:
a. Use a multimeter to measure the resistance between the switch grounding terminal and
grounding point, and make sure the resistance is less than 0.1
b. Use a grounding resistance tester to measure the grounding resistance of the angle iron in
the ground, and make sure the grounding resistance is less than 10. For locations with
high soil resistivity, sprinkle some resistance reducer to reduce soil resistivity or replace soil
around the grounding strip with soil with lower resistance.

The SC 3570 switch series provides two power supply slots. You can install one or two power
supplies for the switch as required. For the power supplies available for the switch and their
specifications, see Intelbras SC 3570 Switch Series Hardware Information and Specifications.
The SC 3570-24G-4X, SC 3570-48G-6X, SC 3570-24S-8G-4X-GL, SC 3570-48S-6X, SC
3570-24GP-4X, and SC 3570-48GP-6X switches are shipped with power supply slot PWR1 empty
and power supply slot PWR2 installed with a filler panel.
The SC 3570-24G-4X, SC 3570-48G-6X, SC 3570-24S-8G-4X-GL, SC 3570-48S-6X, SC
3570-24GP-4X, and SC 3570-48GP-6X switches support shipment with power supplies installed. If
you hope that the switch is shipped with the purchased power supplies installed, contact the
Intelbras sales personnel.
WARNING!
•To avoid bodily injury or switch damage, strictly follow the procedures in Figure 11 and Figure 12
to install and remove a power supply.
•You must provide a circuit breaker for each power supply.
Figure 11 Installation procedure
Figure 12 Removal procedure
CAUTION:
•To prevent damage to the power supply and the connectors on the backplane, insert the power
supply gently. If you encounter a hard resistance when inserting the power supply, pull out the
power supply and insert it again. Make sure the power supply has a good contact with the
connectors.
•When the switch has two power supplies working in 1+1 redundancy, removing one power supply
does not affect system operation. If the switch has only one power supply, removing the power
supply causes power down of the switch.
•If you are not to install a new power supply after removing the old one, install a filler panel in the
slot in time.
•Use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws on a power supply.
