ALLNET PoE Injector Gigabit PoE & PoE+ (15,4W/30W) / plastic housing / "ALL0488v6   Highlights: PoE injector according to IEEE802.3af/at with max. power of 30W 2x RJ45 Gigabit Ports PoE Output 55VDC@30W Midspan PoE PIN's 4/5 (+) and 7/8(-) internal power supply unit compact design incl. 1.5m power cable with IEC-C5 to IEC-CEE7 protective contact cable NEW: Wall mounting capable Intelligent power supply via network without switch With the ALLNET ALL0488V6 Power over Ethernet Injector you can install your PoE-enabled IP devices such as WLAN access points, VoIP phones and much more absolutely independent of existing power sockets. For example, WLAN access points can be installed in the most ideal locations in a building without having to worry about power cabling. Switches that are not PoE-capable can be "retrofitted" with Power over Ethernet at a reasonable price, especially if only a few ports with PoE supply are required. Here, the ALL0488V6 saves the purchase of a PoE switch. The ALLNET ALL0488V6 supports the IEEE802.3af & IEEE802.3at standard with a maximum power of 30W Watt. The ALL0488V6 does not need to be configured. It has an RJ45 input socket and an RJ-45 output socket, which is used to connect the switch and terminal device to the PoE injector. The cable length here can be up to 100 meters between switch and terminal device in total, as is usual in Ethernet. Due to its compact design, the ALLNET ALL0488V6 can be installed very easy. It has an internal power supply and supplies the PoE voltage on pins 4/5 (+) and 7/8 (-).

8-port 10/100/1000M PoE Ethernet Switch with 4-port PoE and 1-port PD Highlights: 8-Port 10/100/1000BaseT(X) with 4 PSE Port and 1 PD Port Compliant with 4x IEEE 802.3af PSE and IEEE802.3at PD Input Metal case with Palm, Size NO power supply needed when powered over PD Port FANLESS DESIGN The device is a powerful, high-performance Gigabit Ethernet Switch, with all 8 ports capable of 10/100/1000Mbps auto-negotiation operation (NWay), which means the switch could automatically negotiate with the connected partners on the network speed and duplex mode. It is ideal for micro-segmenting large networks into smaller, connected subnets for improved performance, enabling the bandwidth demanding multimedia and imaging applications. Moreover, the 10/100/1000Mbps auto-sensing ability provides an easy way to migrate 10/100Mbps to 1000Mbps network with no pain. This switch supports PoE pass-through, having both PD (Powered Device) and PSE (Power Sourcing Equipment) features in one single device, which means the switch could get power from the PD port by connecting to a PSE device and supply power on the 4 PSE ports for connected devices via CAT 5e or better twisted cables. By integrating the data transmitting cable and power cord, it eliminates the effort constructing your network. You could easily connect a Wireless AP or a VoIP phone (PD devices) to this switch without looking outlets for them. Over current protection and circuit shorting protection are also supported to ensure the safety. The switch is plug-n-play without any software to configure and also fully compliant with all kinds of network protocols. Moreover, the rich diagnostic LED indicators on the front-panel provide the operating status of individual port and whole system.
