FAQ

What is the purpose of a PoE injector?
A PoE injector combines power and Ethernet data into a single network cable, allowing compatible devices such as wireless access points to receive power without requiring a nearby AC outlet.

Does this injector support Gigabit Ethernet?
Yes. MA-INJ-4-US supports 10/100/1000 Mbps Gigabit Ethernet while delivering up to 30W of PoE power.

Is it compatible with IEEE 802.3af devices?
Yes. It fully supports IEEE 802.3at and is backward compatible with IEEE 802.3af powered devices.

Can it be used without a PoE network switch?
Yes. The injector allows standard non-PoE switches to power compatible PoE devices through the Ethernet connection.

The Cisco Meraki MA-INJ-4-US is a 30W Gigabit IEEE 802.3at PoE injector designed to provide both power and network connectivity over a single Ethernet cable. It is commonly used with Cisco Meraki wireless access points including MR18, MR26, MR34, MR44, MR45, MR46, MR52, MR53, MR55, MR56, and MR74. It enables PoE deployment without requiring a PoE-enabled network switch while remaining backward compatible with IEEE 802.3af devices.
