D-Link’s DPE-301GI 1-Port PoE Injector is used to provide I.T. Professionals with the benefits of Power over Ethernet (PoE), even when other devices in the network do not support it. With PoE technology, low voltage DC power and Ethernet data signals are combined on a single network cable, which facilitates powering of end devices like IP Cameras, wireless Access Points (APs), and VoIP Phones. This reduces cable clutter, eliminates the need for dedicated electrical outlets on the wall, ceiling, or other unreachable places, reduces installation time, and lowers costs.

The DPE-301GI device supports Gigabit speeds, and can connect to 10Mbps, 100Mbps or 1000Mbps through the RJ-45 interface. This device also supports the IEEE 802.3af and 802.3at PoE/PoE+ standards, which ensures interoperability with other standards-based PoE and PoE+ devices. Small and compact, the DPE-301GI is lightweight, has integrated mounting slots, and is easy to install.

The DPE-301GI provides a power and data connection to a PoE device over a single network cable. It allows I.T. Professionals to mount their PoE devices virtually anywhere in a building, such as on ceilings or near entryways, and eliminates the need for nearby power outlets and attached power supplies. The DPE-301GI combines electrical power with a Gigabit network connection and produces a Gigabit PoE signal, allowing a single Ethernet cable to carry both data and power to a device.

Also known as a “midspan PSE”, the DPE-301GI PoE injector can be used when deploying a multi-port PoE switch is impractical or not feasible. It has two 10/100/1000 RJ-45 ports. One port is for LAN IN, which is the network connection,typically connected to a non-PoE switch or router. The other port isfor PoE OUT, which is the connection that provides both power and data signal to the end device (PD). The DPE-301GI can be located anywhere on the Ethernet link, although it’s typically placed near the switch/router.

Location of the injector does not impact the maximum 100m (328ft.) distance from the switch/router to the end device.

Support for IEEE 802.3at ensures the DPE-301GI can power PoE+ devices up to 30W, such as high power 802.11ac APs and IP cameras with PTZ motors, heaters and blowers.

PoE Injector and PoE Splitter Tandem
Both the DPE-301GI (injector) and DPE-301GS (splitter) can be used together, as a complete PoE transport system. This is especially useful when a PoE switch is not available, and the end device is not PoE capable, but the Network Administrator still prefers the benefits of PoE. Simply install the injector close to the network switch, install the splitter close to the end device, and plug in the cables.

How to use

Connect the LAN IN RJ-45 port of the DPE-301GI to a non‑PoE switch or router using a standard Ethernet cable. Connect the PoE OUT port to the powered device (PD) — for example an access point, IP camera or VoIP phone — using a single Ethernet cable. Plug the injector into an AC power outlet (100–240 V). The injector can be placed anywhere along the Ethernet link but does not change the standard maximum cabling distance of 100 m (328 ft) between switch and PD.

Recommendations

Install the injector near the network switch or router for convenience and route Cat5e/Cat6 cabling to the powered device. For devices requiring higher power (up to 30 W), ensure the PD supports 802.3at. When a device is not PoE-capable, use the DPE-301GI together with a compatible PoE splitter (for example DPE-301GS) to deliver power and then separate data and low-voltage power at the device end.
