This document is an installation guide for AXIS T8123, T8126, and T8128 High PoE devices. It provides instructions for installation and removal of the devices, as well as safety information related to the power supply.
The AXIS High PoE Midspan (model T8123) injects 55 V DC power into Ethernet spare pairs, while the T8126 (12 V) and T8128 (24 V) splitters provide regulated DC to Axis video devices. The guide covers safety requirements, cable specifications, and connection procedures for reliable PoE operation.
Key steps include connecting the Midspan to an approved AC power cable, linking the Data In port to a network switch, and attaching splitters close to the camera. The document also details LED indicators, mounting options, environmental limits, and troubleshooting tips for common power‑up issues.
