Chapter 1. Introduction of the Product
Thank you for choosing the TL-SG1008P 8-Port Gigabit Desktop
Switch with 4-Port PoE.
1.1 Overview of the Product
The TL-SG1008P 8-Port Gigabit Desktop Switch with 4-Port PoE
provides the seamless network connection, which integrates
1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and
10Mbps Ethernet network capabilities.
This PoE Switch is also a Power Sourcing Equipment (PSE*).
Four of the eight Auto-Negotiation RJ45 ports (ports1~4) on the
Switch support Power over Ethernet (PoE*) function, which can
automatically detect and supply power with those IEEE802.3af-
compliant powered devices (PDs*).
*PSE: A device (switch or hub for instance) that will provide
power in a PoE setup.
*PoE: This technology describes a system to transmit electrical
power, along with data, to remote devices over standard
twisted-pair cable in an Ethernet network.
*PD: 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.

Chapter 2. Installation
During the installation procedure, please only use the
accessories equipped with the Switch.
2.1 Mounting the Switch on a Desk
To install the Switch, please follow the steps:
1) Place the Switch on a flat desk.
2) Remove the adhesive backing papers from the rubber
cushions.
3) Turn over the Switch and attach the supplied four rubber
cushions to the recessed areas on the bottom at each
corner of the Switch.
Note
1) Please avoid any heavy thing placed on the Switch.
2) Make sure the power is off before unplugging the power
adapter.
2.2 Power On
The TL-SG1008P Switch can be used with DC power supply.
Powering on the Switch, it will automatically initialize and its LED
indicators will respond as follows:
1) Firstly, the Power LED indicator will light up.
4
2) Then, the 1000Mbps and Link/Act LED indicators will flash
momentarily for one second, which represents a resetting of
the system.
Note
If the LED indicators don’t respond as described above, please
check the power supply and its connection.
Chapter 3.
This Chapter describes the front panel, rear panel and LED indi-
cators of the Switch.

There is a PoE PD connected to the port, which
supply power successfully.
The PoE power circuit may be in short or the
power current may be overloaded.
No PD is connected to the corresponding port, or
no power is supplied according to the power
limits of the port.
The power of all the connected PoE ports is
>=46W. No power may be supplied if additional
PDs are connected.
The power of all the connected PoE ports is
>=53W.
The power of all the connected PoE ports is
<46W, or there is no PD connected to the
corresponding port.
A valid link is established on the port.
The corresponding port is transmitting or
receiving data.
No device is connected to the corresponding
port.
There is a 1000Mbps device connected to the
corresponding port.
There is a 10/100Mbps device connected to the
corresponding port, or there is no device
connected to the corresponding port.

Note
If all PoE PDs power consumption is >= 53W, a priority* will be
arranged among the PoE ports like port-1 = port-2 = port-3 >
port-4, then the system will cut off the power of the
lowest-priority port.
*Priority: This function will help protect the system when the
system power is overloaded. For example, Port 1, 2
and 4 is using 15.4W (maximum power for per port is
15.4W); the system power is 46.2W in total. If there is
an additional PD inserted to Port 3 with 10W, and
then the system will cut off the power of Port 4
because of the overloaded power, this means Port 1, 2
will use 15.4W, and Port3 will use 10W, no power
will be supplied to Port 4.
3.2 Rear Panel
Figure 3-2 TL-SG1008P Switch Rear Panel
The following parts are located on the rear panel:
¾ Power (48V): 48V indicates the input voltage of the power
adapter provided with this TL-SG1008P Switch. The Power
socket is where you will connect the power adapter.
7
¾ PoE Ports (1-4): These ports 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
corresponding LEDs on the front panel.
¾ Ethernet Ports (1-8): Besides the 4 PoE ports, the
TL-SG1008P Switch is also equipped with the other four
10/100/1000Mbps Auto-Negotiation RJ45 ports without PoE
function. 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
corresponding LEDs on the front panel.
Note
Make sure the PDs you connected to the Switch are compliant
with IEEE802.3af.
