Chapter 1. Introduction of the Product
Thank you for choosing the TL-SF1008P 8-Port 10/100Mbps
Desktop PoE Switch.
1.1 Overview of the Product
The TL-SF1008P 8-Port 10/100Mbps Desktop PoE Switch
provides the seamless network connection, which integrates
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 (port-1~port-4) on
the switch support Power over Ethernet (PoE*) function, which
can automatically detect and supply power with those IEEE
802.3af-complaint powered devices (PDs*).

1.2 Convention
The Switch or TL-SF1008P mentioned in this User Guide stands
for TL-SF1008P 8-Port 10/100Mbps Desktop PoE Switch
without any explanation.
1.3 Features
¾Complies with IEEE802.3, IEEE802.3u, IEEE802.3af
standards
¾8 10/100Mbps Auto-Negotiation RJ45 ports with 4-port PoE
function (port-1~port-4), all of them support Auto-MDI/MDIX
¾Supports PoE power up to 15.4W for each PoE port
¾Supports PoE power up to 53W for PoE ports
¾Supports PoE IEEE802.3af compliant PDs
¾Supports IEEE802.3x flow control for Full-duplex Mode and

learning and auto-aging
*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) You can place the Switch on a flat desk.
2) Please insert the power adapter carefully to the power
socket of the switch, and then connect it properly to a power
source through the cable of the switch.
3) Ensure adequate ventilation space around the switch for
dissipating heat and air.
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-SF1008P 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) All the LED indicators except PoE ports LED will light syn-
chronously at first, then all of them included Link/Act LED
(green), 100Mbps LED (green) and PoE MAX LED (red), will
light off at once, which indicates the system initialized well.
2) The Power indicator will light all the time.
Note
If the LED indicators don’t respond as described above, please
check the power supply and its connection.
Chapter 3. Identifying External Components
This Chapter describes the front panel, rear panel and LED indi-
cators of the Switch.

Name Status Indication
On (green) Power on.
Power Off Power off.
On (green)
There is a PoE PD connected to
the port, which supply power
successfully.
On (red)
The PoE power circuit may be in
short, or the power current may
be over that of the PD’s
classification.
PoE ports
(port-1~port-4)
Off
No PD connected to the
corresponding port，or no power
is supplied according to the
power limits of the port.
Flashing
(red)
The power of all the connected
PoE ports is >=53w.
On (red)
The power of all the connected
PoE ports is >=43w. No power
may be supplied if additional PDs
are connected.
PoE MAX
Off
The power of all the connected
PoE ports is <43w, or there is No
PD connected to the
corresponding port.
Flashing
(green)
Data transmitting or receiving on
corresponding port.
On (green)
There is a 10Mbps or 100Mbps
device connected to the
corresponding port.
Link/Act
(port-1~port-8)
Off No device connected to the
corresponding port.

6
On (green)
There is a 100Mbps device
connected to the corresponding
port.
100Mbps
(port-1~port-8)
Off
There is a 10Mbps 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.
3.2 Rear Panel
Figure 3-2 TL-SF1008P Switch Rear Panel
*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, 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.

The following parts are located on the rear panel:
¾Power (48V): 48V indicates the input voltage of the power
adapter provided with this TL-SF1008P Switch. The Power
socket is where you will connect the power adapter.
¾PoE Ports (1-4): These ports support PoE function which
integrates power and data onto one the same 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 10/100Mbps Auto-Negotiation RJ45 Ethernet port. The
working status can be indicated by the corresponding LEDs
on the front panel.
¾Ethernet Ports (1-8): Besides the 4 PoE ports, the
TL-SF1008P Switch is also equipped with the other four
10/100Mbps 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 complaint
with IEEE 802.3af.
