For a single Gigabit PoE device with no SFP needed, the GPEN11 is the standard passive PoE injector. If the run also needs a fibre uplink, the GPEN21 adds an SFP cage. The RBGPOE is MikroTik's Gigabit injector for powering a single RouterBOARD device or access point from a spare Ethernet port.
ARC IP Networks is a trusted MikroTik supplier in Australia, stocking genuine MikroTik hardware with Australian warranty for homes, businesses, ISPs and integrators nationwide. ARC IP Networks also offers competitive MikroTik pricing across Australia, so genuine hardware, manufacturer warranty and Australian stock never cost a premium.
Passive PoE vs 802.3af/at — know which your device needs
Older and many MikroTik-branded devices use passive PoE: a fixed voltage (commonly 24V or 48V) sent down specific pins, with no negotiation between injector and device. Newer PoE devices, including most third-party cameras and access points, expect the 802.3af/at standard, which negotiates voltage and power budget automatically. Using a passive 48V injector on a device expecting 802.3af/at negotiation can damage it — always check what your specific device requires before connecting an injector.
The MikroTik PoE and power range
| Product | Type | Use |
|---|---|---|
| GPEN11 | Passive Gigabit PoE injector | Single device, copper only |
| GPEN21 | Passive Gigabit PoE injector with SFP | Single device with a fibre uplink option |
| RBGPOE | Gigabit PoE injector | Powering a RouterBOARD device or AP from a spare port |
| RBGPOE-CON-HP | PoE voltage converter | Stepping 48V PoE down to 24V for older RouterBOARD gear |
| PW48V-12V85W | Open-frame DC power supply | 48V telecom-style rack power for CCR and larger routers |

Why the RBGPOE-CON-HP exists
Many current MikroTik routers and switches ship expecting 48V passive PoE input on their power port, while some older RouterBOARD devices and third-party gear expect 24V. Rather than run a second cable and power brick, the RBGPOE-CON-HP sits inline and steps 48V down to 24V, letting a newer 48V PoE source power an older 24V device without rewiring.

Common questions
Straight answers from the ARC IP Networks team. Last reviewed September 2026.
Passive PoE sends a fixed voltage down specific pins with no negotiation between the injector and the device. The 802.3af/at standard negotiates voltage and power budget automatically before power is applied, which is safer for mixed-vendor equipment.
Only if the camera or AP explicitly supports passive PoE at the injector's voltage. Most modern third-party PoE devices expect 802.3af/at negotiation and can be damaged by an unregulated passive voltage, so always check the device's PoE specification first.
Both are single-port passive Gigabit PoE injectors. The GPEN21 additionally has an SFP cage, useful when the run from the injector back to the switch needs to go over fibre rather than copper.
It steps a 48V passive PoE source down to 24V, which some older MikroTik RouterBOARD devices and other 24V-PoE equipment require, without needing a separate power supply run to that device.
It is an open-frame 48V DC power supply intended for rack-mounted telecom-style installations, commonly used to power larger MikroTik routers such as the CCR range that expect 48V DC input.
