ALLNET ALL048900V2 PoE Adapter

The ALLNET ALL048900V2 PoE adapter supplies power and data over a single network cable, enabling installation of PoE-capable end devices where no power outlets are available. It supports IEEE802.3af (15.4 W), IEEE802.3at (30 W) and the LT PoE standard (up to 90 W). The adapter is compact, housed in a metal case, and provides one data input port and one Power+Data output port for Gigabit Ethernet connections.

Advantages

The ALL048900V2 automatically detects PoE-capable devices and delivers appropriate power without configuration. It allows flexibility in device placement, reduces the need for dedicated power supplies, and can extend the usable distance for powered devices when used with compatible repeaters, splitters and CAT6 cabling. Non-PoE switches can be upgraded to supply PoE power for a few ports without replacing the entire switch.

Suitable for

• Powering wireless access points (WLAN APs) in locations without mains outlets
• Supplying VoIP phones and IP endpoints
• Upgrading individual ports on non-PoE network switches
• Deployments requiring up to 90 W PoE for high-power PDs

How to use

Connect the ALL048900V2 RJ45 data input port to a network switch or router using a standard Ethernet cable, then connect the RJ45 output port to the PoE device (PD). The adapter requires no configuration and will automatically detect whether the connected device supports PoE and supply power accordingly. Follow standard Ethernet cabling rules: keep a maximum single-cable segment up to 100 metres between switch and terminal unless using approved repeaters or extenders.

Recommendations

Use CAT6 cabling and compatible repeaters/splitters for longer runs or to carry higher PoE power levels. When powering high-wattage devices, verify the device's power class and ensure cable and network components are rated for the required current and heat dissipation. For installations requiring multiple PoE ports, consider cost and management trade-offs between injectors and PoE-capable switches.
