PRODUCT DESCRIPTION
TP-Link 8-Port Gigabit Managed Reverse PoE Switch (TL-RP108GE) - 5 Years Local Warranty
The TL-RP108GE inverts the usual PoE arrangement: seven of its Gigabit ports take passive power in from the devices attached to them, and one port passes power back out, with a DC output port alongside. It is built for wireless and surveillance deployments where power already exists at the edge and the switch itself has no mains outlet — a rooftop, a pole or a sealed enclosure.
Seven Passive PoE-In Ports, One PoE-Out
Ports 1 to 7 are passive PoE-in at 10/100/1000 Mbps auto-negotiation, accepting 24 V or 48 V — but not a mixture of the two, which TP-Link states explicitly. Power is carried on pins 4/5 positive and 7/8 negative. One port is passive PoE-out at the same speeds, whose output voltage follows whatever the PoE-in ports are being fed. A separate DC output port supplies 5 V or 12 V for a device that needs a barrel connector rather than power over Ethernet.
Set the Voltage Before You Connect Anything
Passive PoE does not negotiate: whatever voltage arrives on the cable goes straight to the device. TP-Link therefore publishes two notes worth reading before installation. First, the required voltage of the powered device must be set before connection. Second, the DC out is a power output port and must not be connected to any power source. Both are reproduced in the specifications below — getting either wrong damages hardware, and neither is the kind of mistake a switch can protect you from.
Gigabit Throughput With VLANs and QoS
The switch carries a 16 Gbps switching capacity, a 4 K MAC address table and 16 KB jumbo frame support, using store-and-forward switching. It supports up to 32 VLANs simultaneously out of 4K VLAN IDs, in MTU, port-based and tag forms. QoS handles port-based, 802.1p and DSCP priority across four priority queues, with rate limiting and storm control. L2 features cover IGMP snooping v1/v2/v3, static link aggregation, port mirroring, cable diagnostics and loop prevention.
Sized for the Edge Rather Than the Rack
At 158 x 99.1 x 25 mm the TL-RP108GE is a small desktop-format unit, which is what makes it practical inside an outdoor enclosure or a ceiling void. Power draw is 3.98 W with no powered device attached, 18.01 W at 24 V with a device connected, or 32.74 W at 48 V; heat dissipation is 13.57, 61.41 and 111.64 BTU/h respectively. Power and Link/Act LEDs give local status. Certification is FCC, CE and RoHS, and the operating range is 0 to 40 degrees Celsius.
Ideal For
Singapore wireless and CCTV installers building out pole, rooftop and enclosure sites where power reaches the edge devices but not the switch, and anyone consolidating several passive-PoE feeds onto one Gigabit switch. Supplied by SourceIT with local Singapore warranty, GST invoice and project pricing on request.

TP-Link's specification page prints this model's packet forwarding rate with the unit "Mbps" where a forwarding rate is measured in Mpps. Because the unit as published is not correct, the row is omitted here rather than reproduced or silently corrected. TP-Link also publishes no packet buffer figure, no MTBF and no hardware version for this model, so none is claimed.
Compatibility & Software Support
TP-Link lists the TL-RP108GE among its Omada accessories and publishes a managed feature set for it — VLANs, QoS, IGMP snooping, mirroring, aggregation and cable diagnostics. It does not publish an Omada SDN Controller support row, an Omada App row or a cloud access row for this model, so none is claimed here. Treat it as a locally managed switch unless TP-Link states otherwise for your firmware version.
| Omada SDN Controller | Not published for this model — no controller adoption is claimed |
| Powered Devices | Passive PoE devices at 24 V or 48 V, matched to the input voltage. 24 V and 48 V cannot be mixed across the PoE-in ports |
| PoE Standard | Passive PoE only — this is not an 802.3af/at PoE switch and does not negotiate power with the device |
| DC Output | 5 V or 12 V for a device taking barrel-connector power |
| Interoperability | Standards-based Ethernet on all ports (IEEE 802.3i / 802.3u / 802.3ab / 802.3x) |
Passive PoE is unforgiving: it delivers whatever voltage is on the cable with no negotiation. Send us the models of the devices you intend to power and we will confirm the voltage and wiring before you order.

Frequently Asked Questions — TL-RP108GE
What does "reverse PoE" actually mean?
Normally a switch supplies power to the devices attached to it. Here seven ports take power in from the attached devices and one port passes power back out, with a DC output alongside. It suits sites where mains power reaches the edge devices but not the switch position.
Can I mix 24 V and 48 V devices?
No. TP-Link states plainly that a mixture of 24 V and 48 V is not supported on the PoE-in ports. Pick one voltage for the whole installation.
Is this an 802.3af/at PoE switch?
No. It is passive PoE, which means the voltage on the cable goes straight to the device with no negotiation. Set the device's required voltage before connecting anything, and never connect a power source to the DC output port.
Can it be adopted into an Omada Controller?
TP-Link publishes no Omada SDN Controller support for this model, so we do not claim it. Manage it locally. If central Omada management matters to you, tell us what the site needs and we will suggest a switch that is explicitly supported.
What warranty does SourceIT provide?
Five years local Singapore warranty, under Omada's replacement warranty tier for PoE accessories. Every TL-RP108GE sold by SourceIT comes with a GST invoice.
