Reverse PoE Switch for Remote Access Deployments
When you need to place an access switch or ONU in a ceiling, utility closet, or outdoor enclosure where running a separate power line is impractical, a standard switch won’t cut it. The SG710RP-2S is a PoE powered switch with PoE out that solves this exact problem. Ports 1 through 7 draw power from an upstream PoE source (like a PoE switch or injector), and port 8 supplies PoE to a downstream device. This creates a daisy-chain power link that dramatically simplifies installation and cuts down on labor and material costs.
For IT administrators and network installers, the real value lies in the flexibility. You get a one-click VLAN physical isolation switch to segment traffic without any software configuration – handy for separating guest and corporate networks or isolating IP cameras. Another one-click switch lets you turn port 8’s PoE output on or off, giving you control over power delivery. The wide input voltage range (15–48VDC) means it can run on batteries, solar setups, or any DC source you have handy. Plus, the two DC output jacks (12V/1A and 5V/1A) can power small peripherals like an external fan or a backup radio.
This unmanaged switch is truly plug-and-play – no CLI, no web login, no training needed. Just connect your cables and it starts forwarding at line rate. With jumbo frame support up to 9K bytes, it handles large data packets efficiently, which is useful for camera feeds or file transfers. The natural heat dissipation design keeps it cool even in tight spaces, and the compact metal-like plastic housing (130×76×25mm) can sit on a desk or be wall-mounted with the included brackets.
