PoE Texas 8 Port PoE Injector 48V 120W 802.3af/at

SKU CH-0BZ9-DY4WV

An eight-port midspan injector adds 48 V passive PoE to 10/100 networks for VoIP phones, access points or IP cameras

  • Product typeCable Modem
  • 8 ports power VoIP phones and cameras
  • 120 W supply feeds eight devices at once
  • 48 V output meets 802.3af and 802.3at specs
  • 10/100 Mbps pass-through keeps data flowing
  • Mode B pins 4,5 and 7,8 deliver power

8 Port PoE Injector 48V 120W

This eight port midspan injector adds Power over Ethernet to an existing Fast Ethernet network. It accepts data on eight LAN ports and delivers both data and power on eight PoE output ports using a 48V 120W supply. The unit is designed for installers who need to power multiple low voltage devices from a single location.

IEEE 802.3af and 802.3at Compatible

The injector negotiates Mode B power on pins four, five, seven and eight for devices that follow the 802.3af or 802.3at standards. Passive always on operation means every connected port receives 48V regardless of device class. Installers who require per port power management or gigabit data rates should consider other solutions.

120W Total Power Budget

The 120W supply comfortably handles up to eight 802.3af devices or a mix of 802.3af and 802.3at endpoints within the total budget. Running eight 802.3at devices at full 30W each would exceed the available headroom. Plan the device count and class so the combined draw stays below 120W.

Questions about this item

My switch only has 10/100 Mbps ports — will the injector pass data at that speed?

Yes, the unit is built for 10/100 Mbps Fast Ethernet and its eight Data In and eight Data + Power Out ports preserve signal quality at that rate.

Can I run a mix of 802.3af and 802.3at devices on the same injector?

The injector supports both standards simultaneously; each port delivers 48 V passive power so any compliant VoIP phone, access point or camera will negotiate its own class.

How do I verify each port is delivering power after I connect my cameras?

Check the LED on every Data + Power Out port — a lit indicator confirms 48 V is present on pins 4,5(+) and 7,8(-) for that device.
