1.0 Installation
The switch is a three port Gigabit PoE (Power over Ethernet) Repeater Ethernet switch. The switch
is in full compliance with the IEEE802.3 at standard with one PD (Power Device) port and two PSE
(Power Source Equipment) ports.
This switch can work through receiving power from another PoE switch or equipment through the PD
port. The PSE ports can supply power to other PoE devices (30W maximum). The combined power
output from both PSE ports can be up to 30W, but it also depends upon the PD port supply. For
example, if the PD supply port only delivers 15W, then the two PSE ports can only deliver up to
approximately 13W.
The switch will provide a simple, economic standard for high performance GBit network applications
that allows for the splitting/dividing of one PoE network drop. The 2-Port Gigabit Ethernet Switch is
an ideal choice to promote the department and working group performance. The switch provides
simple and understandable LED indicator lights on the front panel, so that you can quickly judge the
working state of the switch and help to diagnose the network failure.
1.1 Features
• Supports PoE IEEE802.3at compliant
• Supports PoE IEEE802.3af compliant
• Support two power source equipment to supply external devices
• Supports IEEE802.3x flow control for full-duplex mode and back pressure for half-duplex mode
• Support ports Auto MDI/MDIX
• 8K entry MAC address table of the switch with auto-learning and auto-aging
• LED indicators for monitoring PD, PSE, Link / Activity
• No external power supply design
2.0 Checklist
Before you start installing your equipment, verify that the package contains the following:
• The Gigabit POE Repeater Switch
• This User Manual
Please notify your supplier immediately if any of the previously items are missing or damaged.

3.0 Installation
3.1 Installation Method
The site where you install the switch may greatly affect its performance. When installing, please take
the following into consideration.
• Install the switch in a cool, dry place. See technical specifications for the acceptable
temperature and humidity operating ranges.
• Install the switch on a secure, level surface that can support its weight (at least 1Kg).
Alternatively, the switch can be applied to any smooth dry surface using furnished stick-on tape.
• Leave at least 10cm of space at the front and rear of the switch to ensure adequate ventilation.
3.2 Desktop or Shelf Installation
When installing the switch on a shelf on desktop, make sure that the previously mentioned
guidelines in Section 3.1, "Installation Method "are followed for adequate ventilation.
4.0 Powering on the Switch
The switch is powered by your existing central POE Switch. No additional power supply
is required. Simply plug your cable from your central POE switch into the PD port of the
switch and your switch will power on for use.

Connect your devices (computer, router, switch, IP Phone, Wireless Access Point, IP Camera etc.) to
the ports with a CAT-5/CAT-5e/CAT-6 network cable. Since the switch supports Auto MDI/MDI-X, you
can use either a straight through or cross-over network cable.
Figure 1-4. Typical Installation of the Switch
• Connect the switch from the PD port to your central Gigabit PoE Switch.
• Connect your IP Phone from the PSE port on the switch.
• Connect your computer or other networking device to any of the PSE2 ports on the switch.

Appendix A: The Standard RJ-45 Introduction
Regarding cable-making methods, a cable which does not meet the standards of the sequence data
will make the data transmission speed slow, unstable and even be blocked. Table A-1 represents the
standard RJ-45 jack and the connector (Figure A-1) and pin definition:
