Altronix NETWAY8BT 8-Port 802.3bt PoE Midspan
Overview
The Altronix NETWAY8BT is a rack-mounted, network-managed 802.3bt four-pair Power over Ethernet midspan built for security integrators and IT architects deploying high-power networked devices across extended cable runs. With eight gigabit Ethernet ports, the NETWAY8BT delivers up to 90W per port—enough to run power-hungry endpoints like pan-tilt-zoom cameras, advanced access control readers, and IP intercoms without pulling dedicated power infrastructure at each remote location. The 480W total system power budget supports simultaneous operation across all eight ports, making this a practical choice when your existing network switch lacks sufficient PoE++ capacity or when devices are installed well beyond typical switch locations.
Key Features
- 802.3bt 4PPoE Support: Delivers 90W per port across all four twisted pairs—meaning voltage drop over 100 meters of Cat5e or higher cabling stays within safe operating margins. This eliminates the need for expensive powered midline equipment or additional injectors at remote endpoints, a real cost and complexity reducer on enterprise rollouts.
- Eight Gigabit Ports with 480W Aggregate Budget: Auto-sensing 10/100/1000 Mbps connectivity on all eight ports. The 480W total capacity means you can run eight 60W devices simultaneously or a mix of lower-power endpoints plus a few high-draw devices—critical when planning for future device upgrades without hardware replacement.
- 100-Meter Extended Reach: Full 802.3bt delivery at the full 100-meter standard cable length. Eliminates the need for intermediate powered switches or repeaters in warehouse automation, perimeter surveillance, or multi-building campuses where device density doesn't justify a full switch at every location.
- Dual Input Voltage (115VAC / 230VAC): Single unit works in North American or European electrical infrastructure. Simplifies spare parts inventory and deployment logistics across geographically diverse sites—you don't need to stock separate SKUs for different regions.
- Network-Managed Monitoring: Remote status and per-port power consumption visibility via Ethernet management interface. Enables predictive alerting for approaching overload conditions, port faults, or misconfigured endpoints—critical for unattended remote sites where you need to catch problems before they cause downtime.
- Integrated Battery Charging Support: Can charge attached UPS or battery backup systems during normal operation, extending runtime for critical access control or emergency intercoms during mains power loss. Useful for securing perimeter gates or emergency exits that must function even during power outages.
- Rack-Mount 1U Form Factor: Space-efficient design integrates into standard network racks and security equipment enclosures, keeping cable runs organized and simplifying thermal management in equipment rooms.
- UL Listed and CE Marked: Meets North American and European safety standards for permanent commercial installation—required for most enterprise security and IT facility audits.
Integration and Compatibility
The NETWAY8BT operates as a midspan injector, meaning it sits between your existing network switch and end devices. This topology preserves your current switch infrastructure—you don't have to replace a working core switch or oversubscribe its power budget. Simply run Ethernet from your switch to the NETWAY8BT input, then distribute powered lines to remote endpoints. The midspan sits in the middle of the cable run, injecting power without affecting data flow.
Standard Ethernet cabling (Cat5e or better) carries both data and power to the endpoints. The NETWAY8BT requires only mains AC input and a connection to your management network. Per-port power draw of each connected device must not exceed 90W; total concurrent draw across all ports must stay within the 480W aggregate budget. Overshooting either limit triggers port disablement or thermal shutdown to protect the power supply—plan your device inventory carefully and monitor the management interface during initial deployment.
Network managers benefit from centralized visibility into power consumption and operational status. The management interface provides per-port monitoring, enabling troubleshooting of failed devices, detection of misconfigured endpoints drawing excessive power, and planning for future expansions without guesswork about remaining capacity.
When to Choose a Different Model
If you need a fully integrated PoE-managed switch with built-in VLAN, QoS, or advanced network features, consider a dedicated managed PoE++ switch in the Altronix power infrastructure family instead. The NETWAY8BT is a power injector, not a switch replacement—it passes traffic transparently but does not offer network segmentation or traffic shaping. If your total per-port power need exceeds 90W on any single device, you'll need a higher-wattage midspan or alternative power delivery method.
Frequently Asked Questions
Q: Can I use the NETWAY8BT with a non-PoE Ethernet switch?
A: Yes. The NETWAY8BT accepts data from any standard Ethernet switch or router on its input port. Power injection happens downstream at the midspan, so your existing switch does not need to support PoE or PoE++.
Q: What happens if I exceed the 90W per-port limit?
A: The port will disable or the unit may trigger thermal shutdown to prevent power supply damage. Monitor connected device wattage during commissioning and use the management interface to track real power draw. A misconfigured device can starve other ports of power.
Q: Does the NETWAY8BT support SNMP or other management protocols?
A: The unit offers network-managed monitoring and status reporting via Ethernet. Verify specific protocol support (SNMP, web interface, HTTPS) with the manufacturer datasheet or integration documentation for your VMS.
Q: Can I daisy-chain multiple NETWAY8BT units?
A: No. Midspan injectors should not be chained. If you need more than eight powered ports, deploy multiple NETWAY8BT units on separate switch ports, each feeding a different cable segment or building zone.
Q: Is battery backup included?
A: No. The NETWAY8BT has integrated charging capability for external battery systems but does not include a battery. You must purchase and wire an external UPS or battery module if you need runtime during mains power loss.
Q: What power consumption should I plan for in the electrical design?
A: The NETWAY8BT's own internal consumption depends on attached devices. Plan for a mains input capable of delivering the full 480W power budget plus internal losses—typically 500–550W at the breaker to account for efficiency and headroom.
Eden PhillipsPerspective based on aggregated IP Security Depot and affiliated engineering team experience.
I've specified the Altronix NETWAY8BT on several enterprise security rollouts where distributed IP cameras and access control readers were beyond practical PoE switch reach. The 90W per-port ceiling and 4PPoE delivery over 100 meters eliminated the need for powered midline switches at each remote location, significantly reducing both capital cost and operational complexity on sprawling warehouse or campus deployments.
Technical Highlights:
- 802.3bt 4PPoE @ 90W per port: Uses all eight conductors in a Cat5e run, keeping voltage drop within safe margins at the full 100-meter standard cable length. This is a hard requirement on perimeter or multi-building sites where you can't afford intermediate powered equipment.
- 480W aggregate budget across eight ports: Realistic concurrent operation of mid-to-high-power endpoints. I typically plan for a mix—three or four 60W PTZ cameras plus several 30–40W access control readers—and the NETWAY8BT handles it without thermal stress.
- Dual AC input (115V/230V): A practical design choice for global deployments. You don't have to stock region-specific SKUs or manage transformer compatibility during spares logistics.
- Network-managed per-port monitoring: The visibility into power draw and port status is a lifesaver on unattended remote sites. You catch a misconfigured or failing device before it cascades to other ports.
Deployment Considerations:
- Plan your device wattage carefully during site survey. A misconfigured endpoint or unanticipated power draw spike can disable a port and starve downstream devices. Budget 10–15% headroom on the 480W total if you plan any future additions.
- This is a midspan injector, not a network switch. If you need VLAN segmentation, QoS, or loop detection, those must come from your core switch. The NETWAY8BT passes all traffic transparently—it's pure power delivery.
- The integrated battery charging capability is useful but requires you to source and wire an external UPS or battery module separately. Factor that into project scope and cost estimates if mains power loss is a concern.
The NETWAY8BT is well-suited to warehouse automation sites, perimeter security zones, and multi-building campuses where device density doesn't justify a full managed switch at every location but where running power back to a central equipment room isn't practical. It's a straightforward, proven choice for extending PoE reach without reinvesting in switch infrastructure.
