Axis T8154 60W PoE++ Midspan Power Supply - 02740-004

Axis 02740-004 T8154 60W PoE++ Midspan Power Supply

The Axis 02740-004 is a dedicated PoE++ midspan injector designed to retrofit power delivery to IP cameras and network devices that lack integrated PoE support. If you're deploying high-power surveillance equipment or extending deployments into spaces where native PoE infrastructure doesn't exist, this midspan bridges that gap without requiring a full network switch replacement. Maximum output reaches 60W at 55V DC—enough headroom for demanding PTZ cameras, thermal imagers, and multi-sensor platforms that would otherwise demand a dedicated power supply.

Key Features

• 60W output at 55V DC (IEEE 802.3bt Type 3 Class 6 compatible): Delivers enough current for power-hungry surveillance endpoints without cascading infrastructure upgrades. Most fixed IP cameras draw 5–25W; this reserve capacity handles future expansion and peak demand spikes.
• Integrated SFP slot: Eliminates the need for a second fiber module if your network closet already uses fiber backhaul. Supports LC.LX (long-wavelength), LC.SX (short-wavelength), and 1000BASE-T copper SFP transceivers, so you choose the medium that fits your topology.
• Dual RJ45 ports with automatic device detection: The midspan senses whether connected equipment is standard PoE or High PoE (95W+), then adapts power delivery automatically. No manual configuration—plug and power.
• Dual-pair power delivery (pairs 1/2 and 7/8 as negative, 3/6 and 4/5 as positive): Splits power across four cable pairs, reducing current per pair and lowering voltage drop over long cable runs. Matters if your camera sits 100+ meters from the injector.
• Gigabit Ethernet passthrough: Data and power traverse the same cable run; no separate signaling infrastructure required. Supports both EIA 568A and 568B winding standards.
• Operating temperature –10°C to 45°C at full 60W capacity: Indoor deployments work immediately. Outdoor and temperature-sensitive installations can expand to –50°C to 50°C when paired with compatible PTZ outdoor enclosures, though power output may derate slightly in extreme cold.
• Compact form factor (50 × 80 × 184mm; 517g): Mounts flush to a wall or DIN rail in network closets without consuming significant rack real estate. PVC-free construction supports environmental compliance standards in regulated facilities.
• Comprehensive safety certifications: IEC/EN/UL 60950-1, EN 62368-1, FCC Part 15 Class A, plus regional approvals (KC, CCC, CB, GS Mark, RCM, KCC). You'll clear compliance audits without additional testing.

Integration & Compatibility

The 02740-004 integrates into any network supporting standard Ethernet cabling. Accept AC input from 100–240V, 50–60Hz mains—no special power conditioning required. LED indicators on the front panel display power status and PoE detection state, speeding troubleshooting during installation. The device pairs naturally with PoE switches as a downstream injector where switch ports are exhausted, or stands alone to power a single high-demand camera branch. When deployed in NVR and recording infrastructure designs, it decouples power management from network topology, allowing you to position the recorder and power distribution independently.

When to Choose a Different Model

If your endpoint devices draw under 30W and you already have IEEE 802.3at PoE+ (90W total per port) capacity on your switch, a single-port PoE+ injector or native PoE+ switch ports eliminate this midspan entirely. The 02740-004 shines when you're powering multiple high-draw cameras from a single uplink, or when fiber connectivity is non-negotiable for noise immunity or distance.

Deployment Scenarios

• Retrofit existing IP camera installations lacking PoE without rewiring the entire closet.
• Long-distance fiber runs where copper PoE injectors would introduce noise or require frequent repeaters.
• Outdoor thermal and panoramic camera arrays demanding peak 50–60W per unit.
• Legacy network infrastructure where PoE-capable switch upgrades are deferred or infeasible.

Frequently Asked Questions

Q: Does the Axis 02740-004 work with non-Axis IP cameras?

A: Yes. The midspan delivers standard IEEE 802.3bt Type 3 PoE++ at 55V DC. Any IP camera or network device with a standard RJ45 port and support for High PoE input (55V DC) will work, regardless of manufacturer.

Q: What's the maximum cable distance I can run from the 02740-004 to the camera?

A: Standard Ethernet limits are 100 meters (328 feet) for copper. The dual-pair power distribution in the midspan reduces per-pair current density, which can extend practical distance slightly in low-current scenarios, but 100m remains the hard limit for category 5e or 6 cabling.

Q: Can I daisy-chain multiple 02740-004 units to power several cameras?

A: No. Each midspan is a single-port injector. Power one camera per unit. If you need to power multiple cameras, install multiple midspsans or upgrade to a PoE++ switch with native 60W per-port capacity.

Q: Does the 02740-004 include DIN rail clips?

A: DIN rail mounting clips are available as optional accessories. The unit ships ready for wall mounting; order the clip kit separately if you plan to install it in a standard 35mm DIN rail rack.

Q: What input voltage does the 02740-004 require?

A: AC 100–240V, 50–60Hz. Works globally without voltage converters. Use a UPS or backup power system if your installation requires power continuity during mains failure.

Q: Is the Axis 02740-004 NDAA Section 889 compliant?

A: No NDAA claim appears in the manufacturer documentation for this model. If federal procurement compliance is required, consult the manufacturer directly or contact your integrator for current certification status.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Axis 02740-004 (often searched as 02740 004) is the right tool for a specific problem: you need to inject 60W of stable DC power into a single high-draw camera or network device, and your existing switch infrastructure either doesn't have spare PoE capacity or isn't PoE-capable at all. The 55V DC output at IEEE 802.3bt Type 3 Class 6 spec means you're getting genuine High PoE, not undersized injection masquerading as such.

Technical Highlights:

• 55V DC at 60W max output: More than adequate for thermal imagers (often 40–50W), multi-sensor heads, and motorized PTZ platforms. At full load, you're still compliant with IEEE 802.3bt—not pushing into undocumented territory.
• Dual-pair PoE delivery (1/2 negative, 3/6 & 4/5 positive, 7/8 negative): Current is split, so voltage drop is manageable even at 100m cable distance. A single-pair injection would leave you struggling with voltage regulation on longer runs.
• SFP slot with auto-detection: If your network is fiber-based, you avoid buying a separate fiber-to-copper converter module. Auto-sensing for standard vs. High PoE devices saves configuration headaches on mixed deployments.

Deployment Considerations:

• Single-port injector—don't try to power multiple cameras from one unit. If you need to scale, either install multiple midspsans or bite the bullet and upgrade the switch backbone to native PoE++.
• Watch the temperature spec: full 60W is only guaranteed down to –10°C. If you're deploying outdoors in harsh climates, pair this with Axis PTZ outdoor enclosures that extend operating range to –50°C, though power output will derate in deep cold.
• Fiber SFP transceivers are optional accessories—they don't ship in the box. Copper RJ45 is standard.

This midspan is purpose-built for retrofit scenarios where you've got a single-camera power bottleneck and don't want to replace your entire switch or run a separate 110V line. It's not a substitute for proper PoE++ switch infrastructure in greenfield designs; it's the pragmatic answer to 'my legacy network can't natively PoE this thermal camera.' For that use case, it's solid.
