Gigabit, Mode B 4-Port PoE Injector without power supply: Power an IP camera, desktop phone, WiFi access point, or other low-voltage devices through a network data cable using this Power over Ethernet (PoE) injector. The PoE injector takes power from a DC power source (power supply sold separately) and adds it to your Ethernet data cable (Cat5, Cat5e, Cat6) to your device.Save on network upgrades and device installations: Power over Ethernet delivers power up to 328 feet from the PoE injector, eliminating the need for AC power near your powered device. With this PoE injector, you can add power to your data cable at a fraction of the cost of upgrading to a PoE-capable network switch.Passive PoE for flexibility: A passive PoE injector delivers the same voltage as its power source. Pair this injector with a 48V DC power supply to power devices compatible with 802.3af, or use a 24V power supply with 24V passive PoE devices such as certain access points.Specifications: 4-Port Gigabit Ethernet Injector 4 Shielded RJ-45 LAN ports 4 Shielded RJ-45 LAN+PoE ports Supports 10/100/1000 Mbps data rates Wall-mountable and stackable design 1000 mA automatic resettable fuse on each port Same voltage output on all ports; power shared as needed Compatible with any Ethernet switch, including PoE and non-PoE switches LED status indicators: - Green: Normal voltage - Red: Reverse polarity Operating temperature: 0C to 65C Mode B operation: - Pins 4, 5 supply power - Pins 7, 8 return Reversible polarity with compatible adapter Power is always on; no auto-negotiation required Material: Plastic Color: Blue Package Contents: 1 x Gigabit Passive PoE Module Note: The package includes only the items listed above.
