Functions and features

The AXIS T8121 High PoE Midspan 1-port injects 48V DC power into data-carrying Ethernet cabling.
It maintains IEEE802.3af specification parameters while doubling the output power. These power
levels allowed a new range of Ethernet-based applications such as PTZ Cameras to use the High PoE
Midspan.

Preliminary steps

• Ensure AC power is applied to the AXIS T8121, using an operational AC cable with appropri-
ate ground connection.
• Ensure that output Ethernet cable is connected to the Data & Power Out port.
• Verify that a power ready Ethernet compatible device or splitter is connected.
Note:
Do not use a cross over cable between the AXIS T8121 output port and the powered device.
