PoE Texas 12-Port Gigabit Passive Midspan Injector - Upgrade to PoE

In this review of the PoE Texas 12-port midspan injector, the bottom line is straightforward: network installers and small IT teams who need a tidy, cost-effective way to add PoE+ to existing switches will appreciate this unit. It instantly converts non-PoE switches into power-delivering ports without replacing your switch, and the shared 120 watt budget across the three sets of four ports is the single biggest reason to consider it. The injector is practical for IP cameras, VoIP phones, and access points when total device wattage is planned in advance.

Key Features

• 12 Gigabit Ports: Provides 10/100/1000 data throughput on both Data In and Data + PoE Out ports for full gigabit performance.
• 120W Shared Power Budget: Includes a 48V, 120 watt UL power supply that delivers a shared power pool for up to 12 devices when distributed across the three sets.
• Three 4-Port Sets: Groups ports into three sets of four with per-set indicator lights so you can see normal operation or when a set reaches maximum current.
• Mode A or B Compatibility: Can be configured for Mode A or Mode B to work with IEEE 802.3af/at devices from common vendors without replacing endpoints.
• VLAN Passthrough: Transparent VLAN passthrough means the injector does not interfere with existing network segmentation or managed switch features.
• Quiet Operation: Designed to run cool and quietly compared with full PoE switches, making it suitable for small offices or server rooms.

Who It's For

The PoE Texas midspan is aimed at installers and small IT teams who need to add power to up to a dozen devices without buying a new PoE switch. It works well for security camera deployments, powering VoIP phones, or supplying access points where a centralized 48V supply and gigabit links are required.

It is less suitable for environments that need guaranteed per-port power allocation or full 802.3bt support out of the box; those requiring per-port high-power delivery should consider solutions that provide individual power guarantees or add the second power supply option from the vendor for 802.3bt compatibility.

Pros & Cons

Pros

• Simple way to add PoE+ to an existing non-PoE switch without replacing infrastructure.
• Gigabit-capable ports preserve network speed for cameras and access points.
• Clear indicator lights make it easy to spot a set that has reached maximum current.
• Includes a UL-approved 48V, 120W power supply and a one-year replacement warranty.

Cons

• Shared 120W budget means you must calculate combined device wattage carefully before deployment.
• Requires additional patch cables and may need a second power supply (sold separately) for full 802.3bt use.

Our Verdict

The PoE Texas 12-port midspan injector is a practical, value-oriented choice for adding PoE+ where a full PoE switch would be more expensive or unnecessary. It preserves gigabit performance, offers clear status lights for load monitoring, and includes a UL power supply, so installers who plan device wattage carefully will find it a cost-effective way to power cameras, phones, and access points.

Frequently Asked Questions

Will this power 12 devices at full PoE+ simultaneously?
The unit has a shared 120W budget, so simultaneous full PoE+ on all 12 ports will exceed the available power; plan combined device wattage accordingly.

Does it support 802.3bt devices?
Not by default; 802.3bt compatibility requires a second power supply sold separately as noted by the vendor.

Do I need extra cables to install it?
Yes, additional patch cables are required to connect your switch to the injector and from the injector to the patch panel or endpoints.
