Ethernet Switch with 4 PoE Ports. This Switch integrates 100Mbps
Fast Ethernet and 10Mbps Ethernet connections in a highly flexible
package. The Switch also has four Power over Ethernet (PoE) ports
which automatically detect the presence of IEEE 802.3af-compliant
powered devices (PD) and provide up to 15.4W of power to the device.
Common PoE devices include WLAN access points, IP phones, and
IP cameras. The Switch will automatically detect the network
appliance’s requirements, and supply the required power to each
appliance.

INTRODUCTION
This chapter describes the features of the 8-Port 10/100Mbps Fast
Ethernet Switch with 4-Port PoE and some background information
about Ethernet/Fast Ethernet, Switching and Power over Ethernet
technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for high
performance networks. 100BASE-T (Fast Ethernet) provides a non-
disruptive, smooth evolution from the current 10BASE-T technology.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3
LAN committee. It is an extension of the 10Mbps Ethernet standard
with the ability to transmit and receive data at 100Mbps, while
adhering to the CSMA/CD Ethernet protocol. Since 100Mbps Fast
Ethernet is compatible with all other 10Mbps Ethernet environments,
it allows for a straightforward upgrade and takes advantage of the
existing investment in hardware, software, and personnel training.
Power over Ethernet (PoE)
Power over Ethernet (PoE) combines power and data onto one single
cabling infrastructure, eliminating the need to have AC power
available at all locations.
Using PoE, power and data are carried on the same cable. Category 5
or higher cables up to 328 feet (100 meters) must be used, and PoE
will provide power to any 802.3af compliant PoE device, such as IP
telephones, wireless LAN access points and IP security cameras.
PoE is already widely adopted in the market, saving installation costs
by eliminating the need to install separate electrical wiring and outlets.

UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the
Switch.
Unpacking
Open the box containing the Switch and carefully unpack its contents.

Four rubber feet
User’s Guide
If an item is found to be missing or damaged, please contact your local
reseller for a replacement.
Installation
Ensure the following before installing your switch:
The surface must support at least 3.3 lbs (1.5 kg) for the Switch.
The power outlet should be within 6 feet (1.82 meters) of the
Switch.
Visually inspect the DC power jack and make sure that it is fully
secured to the power adapter.
Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Do not place heavy
objects on the Switch.

Connecting Network Cable
The Switch supports 8 10/100M Ethernet ports with ports 1 through 4
supporting PoE. These PoE ports will automatically activate when a
compatible terminal is connected, and the Switch will supply power
through the Ethernet port to the connected PoE powered device (PD).
For the Legacy devices that are not compatible with PoE, the PoE port
will not supply power to the port. This feature allows users to freely
and safely mix legacy and PoE compatible devices on their network.
The Switch supports 10Mbps Ethernet and 100Mbps Fast Ethernet
and it runs both in half and full duplex mode using two pair of
Category 5 cable.
These RJ-45 ports are Auto-MDI type port. The Switch can auto
transform to am MDI-II or MDI-X type, so you do not have to worry
about whether you are using a standard or crossover RJ-45 cable.

IDENTIFYING EXTERNAL COMPONENTS
This chapter describes the front panel, rear panel, and LED indicators
of the Switch.
Front Panel
The figure below shows the front panel of the Switch.
Figure 1. Front panel
Comprehensive LED indicators display the status of the switch and
the network (see the Understanding LED Indicators section below).
Rear Panel
Figure 2. Rear panel
PoE Ports (Port 1-4):
These ports are PoE Enabled ports. The PoE port will automatically be
activated when a PoE compatible terminal is identified, and the
Switch will supply power through the Ethernet port to the connected
PoE device.
For Legacy devices that are not PoE compatible, the PoE port will not
supply the power to this device. This feature allows users to mix
legacy and PoE compatible devices on their network.

10
These ports support network speeds of either 10Mbps or 100Mbps,
and can operate in half- and full- duplex transfer modes. These ports
also support automatic MDI/MDIX crossover detection which
provides true “plug and play” capability.
Ethernet Ports (Port 5-8):
These ports support network speeds of either 10Mbps or 100Mbps,
and can operate in half- and full-duplex transfer modes. These ports
also support automatic MDI/MDIX crossover detection.
DC Power Jack:
Power is supplied through an external AC power adapter. Check the
technical specification section for information about the AC power
input voltage.
Since the switch does not include a power switch, plugging its power
adapter into a power outlet will immediately power it on.

UNDERSTANDING LED INDICATORS
The front panel LEDs provide instant status feedback, and helps
monitor and troubleshoot when needed.
Figure 3. LED indicators of the Switch
System LED
Power: (Power Indicator)
On: The Switch is receiving power.
Off: The Switch is not receiving power.
PoE status LEDs (Port 1 - Port 4)
PoE Status:
Green: A PoE powered device (PD) is connected to the port and
power is being supplied properly.
Red: One of the following problems has occurred:
•PoE power circuit shortage
•Power over current: the current is greater than the PD’s
classification
•Out of range of PoE voltage of 44 - 57 VDC output
Off: No PoE powered device (PD) is connected to the port.

12
PoE MAX:
On: The system has less than 7.5W of power remaining to power
PoE devices. If this LED is on, the system will not provide
power to any additional PoE devices connected to the Switch.
Off: The system has more than 7.5W of power remaining to power
PoE devices.
Ethernet port status LEDs (Ports 1~8)
10/100M Link/ACT:
10M: When on, the port is successfully connected to a device running
at 10 Mbps. When flashing, the port is transmitting or receiving
data.
100M: When on, the port is successfully connected to a device
running at 100 Mbps. When flashing, the port is transmitting or
receiving data.
Off: No link.
PoE Rule
PoE Max: this function helps to protect the PoE Switch and to
stabilize the power transmitted to the powered devices (PD).
If the remaining system power for PoE is below 7.5 watts, the PoE
MAX LED will light up and the system will not provide power to any
PoE devices connected to the switch to protect the PoE Switch itself
and to stabilize the power transmitted to other PoE devices plugged in
the Switch.

13
Example: If there are PoE devices connected to the Switch with a total
power consumption of 25 watts, the Switch only has 5 watts
remaining as a buffer, and the PoE MAX LED will light up. If another
POE PD inserted, the system will not provide power to the additional
POE PD.
Priority: If the PoE devices connected to the Switch exceed the 30
watt power consumption limit, the Switch will provide power to the
devices according to their priority. Priority is determined by the
number of the port, with port 1 having the highest priority and port 4
having the lowest.
Example: A PoE device connected to Port 2 is using 14 watts and
another device connected to Port 3 is using 8 watts. If a PoE device is
connected to Port 1 which requires 10 watts, the Switch will provide
power to Ports 1 and 2, and not Port 3.
