The Gigabit Unmanaged Switch provides you with a high-performance, low-cost, easy-
to-use, seamless and standard upgrade to boost your old network to 1000Mbps.
By increasing the speed of your network server and backbone connections, the
Gigabit Unmanaged Switch makes Gigabit a reality. Power users in the home, office,
workgroup, or creative production environment can now move large, bandwidth-
intensive files faster. Graphics, CGI, CAD, multimedia files and other large files moved
by some applications can be transferred across the network almost instantly.
The Gigabit Unmanaged Switch features a non-blocking switching architecture that
forwards and filters packets at full wire-speed for maximum throughput. The switch
supports MAC address auto-learning and auto-aging, IEEE802.3x flow control for full-
duplex mode and backpressure for half-duplex mode. It is compatible with all 10Mbps,
100Mbps and 1000Mbps Ethernet devices because it is standard-based. It protects
your existing network investments while providing you with a straightforward migration
path to faster Gigabit speed.
The Gigabit Unmanaged Switch is plug-and-play and no configuration is required.
Auto MDI/MDI-X cable detection on all ports eliminates the need for crossover cable
or Uplink port. Each port can be used as general port or Uplink port, and any port can
be simply plugged into a server, a hub, a router or a switch, using the straight cable
or crossover cable. Diagnostic LEDs which display link status and activity, allow you to
quickly detect and correct problems on the network.
TL-SG1008PE is a Power Sourcing Equipment (PSE*). The 8 Auto-Negotiation RJ45
ports support Power over Ethernet (PoE*) function, which can automatically detect and
supply power with those IEEE802.3af/IEEE802.3at-compliant powered devices (PDs*).
Note:
*PSE is a device (switch or hub for instance) that will provide power in a PoE setup.

*PoE is a technology that describes a system to transmit electrical power, along with

data, to remote devices over standard twisted-pair cable in an Ethernet network.
*PD is a device powered by a PSE and thus consumes energy. Examples include

powering IP telephones, wireless LAN access points, network cameras, network hubs,
embedded computers etc.

10/100/1000Mbps RJ45 Port and PoE Port
TL-SG1008PE switch is equipped with 8 10/100/1000Mbps Auto-Negotiation RJ45
ports and all of them support PoE function.
The 8 10/100/1000Mbps RJ45 ports are designed to connect to the device with
a bandwidth of 10Mbps, 100Mbps or 1000Mbps. Once the network devices are
connected to these 8 ports through the network cable, the switch will make them
plug and play according to the Auto-MDI/MDIX detection. The working status can be
indicated by the Link/Act LEDs and 1000Mbps LEDs on the front panel.
The 8 ports also support PoE function which integrates power and data onto
one Ethernet cable. Once the device you connect to the switch is identified, the
switch will supply power through the PoE port, and then you can use it as a
10/100/1000Mbps Auto-Negotiation RJ45 Ethernet port. The working status can be
indicated by the PoE MAX LED and PoE Status LEDs on the front panel.
Note:
If all PoE PDs power consumption is >=124W, a priority* will be arranged among the

PoE ports like port 1 > port 2 > port 3 > port 4 > port 5 > port 6 > port 7 > port 8,
then the system will cut off the power of the lowest-priority port.
*Priority is to protect the system when the system power is overloaded. For example,

Port 1, 2, 4 and 7 is using 30; the system power is 120W in total. If there is an
additional PD inserted to Port 3 with 25W, and then the system will cut off the power
of Port 7 because of the overloaded power, this means Port 1, 2 and 4 will use 30W,
and Port 3 will use 25W, no power will be supplied to Port 7.
Make sure the PDs you connected to the switch are compliant with IEEE802.3af/

IEEE802.3at standard.

Site Requirements

Temperature/Humidity
40℃
0℃
Please keep a proper temperature and humidity in the equipment room. Too high/low
humidity may lead to bad insulation, electricity leakage, mechanical property changes
and corrosions. Too high temperature may accelerate aging of the insulation materials
and can thus significantly shorten the service life of the device. For normal temperature
and humidity of the device, please check the following table.
Environment Temperature Humidity
Operating 0℃~ 40℃10% ~ 90%RH Non-condensing
Storage -40℃~ 70℃5% ~ 90%RH Non-condensing
Clearness
The dust accumulated on the switch can be absorbed by static electricity and result
in poor contact of metal contact points. Some measures have been taken for the
device to prevent static electricity, but too strong static electricity can cause deadly
damage to the electronic elements on the internal circuit board. To avoid the effect of
static electricity on the operation of the Switch, please attach much importance to the
following items:
Dust the device regularly, and keep the indoor air clean.

Keep the device well grounded and ensure static electricity has been transferred.

Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be affected
by external interferences, such as conducted emission by capacitance coupling,
inductance coupling, and impedance coupling. To decrease the interferences, please
make sure to take the following measures:
Use the power supply that can effectively filter interference from the power grid.

Keep the device far from high-frequency, strong-current devices, such as radio

transmitting station.
Use electromagnetic shielding when necessary.


10
Gigabit Unmanaged Switch
Lightening Protection
Extremely high voltage currents can be produced instantly when lightning occurs and the air
in the electric discharge path can be instantly heated up to 20,000℃. As this instant current
is strong enough to damage electronic devices, more effective lightning protection measures
should be taken.
Ensure the rack and device are well earthed.

Make sure the power socket has a good contact with the ground.

Keep a reasonable cabling system and avoid induced lightning.

Use the signal SPD (Surge Protective Device) when wiring outdoor.

Note: For detailed lightning protection measures, please refer to Chapter 3
Lightning Protection.

In the actual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are different. A reasonable cabling
system can decrease the damage of induced lightning to devices.
Note: It's not recommended using Ethernet cables outdoors. When cabling outdoors,
please use a signal lightning arrester.
Requirements for Cabling Outdoors

Aerial cabling without safeguard is not allowed.

It’s not allowed cabling down the building to connect network devices in different

floors.
Outdoor cables should be buried and paved to the indoor through basement. A

piece of steel wire should be paved underground along the pipe and connected to
the lightning protection terminal of the building for shielding. Before connecting the
cable to the device, install a signal lightning arrester on the corresponding port.
When an aerial cable is set up, the cable should be through a metal pipe (15m long

at least) before coming into the building. The two ends of this metal pipe should
be grounded. Before connecting the cable to the device, install a signal lightning
arrester on the corresponding port.
It’s not necessary to pave STP cables through pipes. The shielded layer of STP cable

should be well grounded. Before connecting the cable to the device, install a signal
lightning arrester on the corresponding port.

14
Gigabit Unmanaged Switch
Requirements for Cabling Indoors

When cabling indoors, keep a certain distance away from the devices that may cause
high-frequency interferences, such as down-conductor cable, powerline, power
transformer and electromotor.
The main cable should be paved in the metal raceway of the access shaft. When

cabling, keep the loop area formed by the cable itself as small as possible.
Requirements for the distance between Ethernet cable and other pipelines are

shown in the table.

Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body from
electric shock.
In different environments, the device may be grounded differently. The following
