Industrial multi-gigabit PoE++ with a 10G uplink
8 × 2.5G PoE++1 × 10G SFP+48–57 V DC input480 W shared maximum
The TRENDnet TI-BG5091 combines eight 2.5G PoE++ copper ports and one 10G SFP+ uplink in a compact industrial switch. This exact non-B model requires external 48–57 V DC. Fast PoE, multiple power inputs and DIN-rail/wall mounting support planned industrial installations with compatible powered endpoints.
Best For: Protected industrial networks needing multi-gigabit powered endpoints and a compatible 10G uplink.
Before you order: Select a separate suitable 48–57 V DC supply. The maximum shared PoE budget is 480 W, with up to 95 W manufacturer PSE rating per port subject to shared capacity and compatibility. Supply capacity must also cover switch overhead; an optional 160 W adapter cannot deliver 480 W PoE. This non-B model does not support 24 V input. IP50 does not provide water protection.
What's in the Box
- TI-BG5091, removable terminal block and DIN-rail/wall mounting kit.
- External power supply/adapter selected separately for the actual input and PoE demand.
- SFP+/SFP module or compatible uplink cable and network cables separate.
What It Means in Practice
- Connect eight 10/100/1000/2500 Mbps copper devices and power compatible PoE devices within the shared budget.
- Use a compatible 1G or 10G module/link in the SFP+ cage.
- Design redundant external power sources and alarm wiring where required.
- Use Fast PoE for power delivery shortly after switch power-on without assuming a battery-backed installation.
What Will Not Work
- No 24 V input support for this exact model.
- Eight simultaneous 95 W loads exceed the 480 W shared limit.
- No configurable managed VLAN, SNMP or Layer 3 functions are established.
- No direct mains input, included PSU, built-in UPS or water protection.

Technical Specifications
Frequently Asked Questions
Singular Expert Insight
Treat the 480 W figure as an installation limit requiring adequate external power, not a promise from any listed adapter. Verify the 48–57 V input, supply headroom and combined endpoint draw, then plan the 10G uplink, grounding and protected mounting.
Buyer’s Guide
✓ Buy it if You need industrial 2.5G PoE++ access with suitable external 48–57 V DC power.
✕ Skip it if You need 24 V input support, managed network controls or an included mains PSU.
→ Also consider 48–57 V supply capacity, combined PoE draw, source redundancy, optics/cabling and mounting protection.
