1 Introduction
1-1 Overview of Cross 4/PoE Lite
The Fast switch, an 8 port desktop Fast switch, meets the demand o
bandwidth. This desktop switch seamlessly integrates with the rest o the network
through its auto-negotiating and non-blocking design. To break through the
bottlenecks at the core o network, the switch provides up to 1.6Gbps aggregate
bandwidth and seamless migration and the most cost e ective method or 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 in rastructure. The PSE switch complies with IEEE 802.3a , its
advanced auto-sensing algorithm enables providing power devices (PD) discovery,
classi ication, current limit, and other necessary unctions. It also supports high
sa ety with short circuit protection and power-out auto-detection to PD.

2 Installation
2-1 Starting Cross 4/PoE Lite Up
This section will give users a quick start:
1. Take your Cross 4/PoE Lite out o the package box.
2. Power on the Cross 4/PoE Lite. Re er to the Wiring the Power Inputs
section or wiring instructions. A ter the Cross 4/PoE Lite is powered on, the
power LED on the Cross 4/PoE Lite will light up. Re er to the LED
Indicators section or descriptions o the unction o each LED indicators.
3. Connect one side o an Ethernet cable into the Cross 4/PoE Lite’s TP port,
while the other side is connected to the attached device. The LED will light
up when the cable is correctly connected. Re er to the LED Indicators
section or descriptions o the unction o each LED indicator.
4. A ter all necessary connections are established, and the corresponding LED
indicators all light up and indicate that each status is normal, the installation
is now inished.
2-1-1 Hardware and Cable Installation
At the beginning, please do irst:
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 o the switch also allows the
connection to server or PC to ree rom cabling problems.
1. In the switch, TP port supports MDI/MDI-X auto-crossover, so both types o
cable, straight-through (Cable pin-outs or RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6
in 10/100M TP) and crossed-over (Cable pin-outs or RJ-45 jack 1, 2, 3, 6
to 3, 6, 1, 2) can be used. It means you do not have to tell rom them, just
plug it.
2. Use Cat. 5 grade RJ-45 TP cable to connect to a TP port o 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, or each RJ-45 port to be connected to
a Fast 10/100 TP device.
4. For Fast Ethernet TP network connection
5. The grade o the cable must be Cat. 5 or Cat. 5e with a maximum length o
100 meters.
6. Insert the power cord. The embedded internal power unit using di erent AC
power cord is available or di erent areas.
PSE TP Switch with Powered Device (PD)
1. Connect the PSE switch to an AC power source.
2. Install the TP media cable to the IEEE 802.3a PD or port 1 to 4. (See Fig.
2)
5

Note: It can work as a pure switch that connects to non-PoE
devices
1. Install the media cable or network connection.
2. Port 5 to 8 are pure TP ports or non-PoE devices.
2-1-2 Cabling Requirements
To ensure a success ul installation and keep the network per ormance
good, please take a care on the cabling requirement. Cables with worse
speci ication will render the LAN to work poorly.
2-1-2-1 Cabling Requirements for TP Ports
For Fast Ethernet TP network connection
The grade o the cable must be Cat. 5 or Cat. 5e with a maximum length o
100 meters.
This device supports MDI/MDI-X auto-crossover, so both types o cable,
straight-through and cross-over can be used.
Straight-through cable: pin-outs or RJ-45 connector 1,2,3,6 to 1,2,3,6
Cross-over cable: pin-outs or RJ-45 connector 1,2,3,6 to 3,6,1,2
