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.

4 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. The carton should contain the following items: One 8-Port 10/100Mbps Fast Ethernet Switch with 4 PoE Ports One AC power adapter 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.

7 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.

8 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.

9 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.

10 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.

11 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.

12 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.
