2. Overview
2.1 Introduction
2.2 Features
2.3 What’s Included
The Fast switch, an 8 port desktop Fast switch, meets the demand of bandwidth. This desktop switch seamlessly
integrates with the rest of the network through its auto-negotiating and non-blocking design. To break through the
bottlenecks at the core of network, the switch provides up to 1.6 Gbps aggregate bandwidth and seamless migration and
the most cost effective method for bringing high-speed networking to the desktop.
PoE allows power to be supplied to end devices, such as Wireless Access Points or VoIP Phones, directly through the
existing LAN cables. By supplying the power endpoint, you can centralize power distribution and backup without the need
to increase infrastructure. The PSE switch complies with IEEE 802.3af, its advanced auto-sensing algorithm enables
providing power devices (PD) discovery, classification, current limit, and other necessary functions. It also supports high
safety with short circuit protection and power-out auto-detection to PD.
• Conforms to IEEE 802.3 10Base-T,IEEE 802.3u 100Base-TX and IEEE 802.3x flow control standards
• Supports 10/100Mbps auto-detect half/full duplex
• Supports TP interface MDI/MDI-X auto crossover
• Supports 802.3x flow control pause packet for full duplex
• Supports IEEE 802.3af compliant
• LEDs to indicate: Link/Act, Speed, Power Status and PoE activity
• Alarm contact function
• Desktop for easy installation
• Auto detect powered device and consumption levels
• Smart feature for PD on/off, PD detection, power level, PD status and power feeding priority
• Automatic Fault Detection(Over/Under Voltage & Current)
• Thermal shutdown protection(Tj>150C)

3. Installation
3.1 Starting LPB208A-R2 Up
This section will give users a quick start:
1. Take your LPB208A-R2 out of the package box.
2. Power on the LPB208A-R2. Refer to the Wiring the Power Inputs section for wiring instructions. After the LPB208A-R2
is powered on, the power LED on the LPB208A-R2 will light up. Refer to the LED Indicators section for descriptions of
the function of each LED indicators.
3. Connect one side of an Ethernet cable into the LPB208A-R2's TP port, while the other side is connected to the
attached device. The LED will light up when the cable is correctly connected. Refer to the LED Indicators section for
descriptions of the function of each LED indicator
4. After all necessary connections are established, and the corresponding LED indicators all light up and indicate that
each status is normal, the installation is now finished.
At the beginning, please follow below instruction first:
With the plug and play design, the Fast switch is easy in installation and use. Network and port status can be easily
monitored and done trouble-shooting via diagnostic LEDs. Wiring auto crossover on all ports of the switch also allows the
connection to server or PC to free from cabling problems.
1. In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of cable, straight-through (Cable pin-outs for
RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP) and crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1,
2) can be used. It means you do not have to tell from them, just plug it.
2. Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the other end is connected to a network-
aware device such as a workstation or a server.
3. Repeat the above steps, as needed, for each RJ-45 port to be connected to a Fast 10/100 TP device.
4. For Fast Ethernet TP network connection.
5. The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters.
6. Insert the power cord. The embedded internal power unit using different AC power cord is available for different areas.
3.2 Hardware and Cable Installation

3.2 Hardware and Cable Installation (Cont.)
PSE TP Switch with Powered Device (PD)
Cabling Requirements
Cabling Requirements for TP Ports
1. Connect the PSE switch to an AC power source.
2. Install the TP media cable to the IEEE 802.3af PD for port 1 to 4.
3. Install the media cable for network connection.
4. Port 5 to 8 are pure TP ports for non-PoE devices.
To ensure a successful installation and keep the network performance good, please take a care on the cabling
requirement. Cables with worse specification will render the LAN to work poorly.
For Fast Ethernet TP network connection:
Straight-through cable: pin-outs for RJ-45 connector 1,2,3,6 to 1,2,3,6
Cross-over cable: pin-outs for RJ-45 connector 1,2,3,6 to 3,6,1,2
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters.
This device supports MDI/MDI-X auto-crossover, so both types of cable, straight-through and cross-over can be used.
