Power supply units (PSU)
PSU description
The PSU is an indoor unit that is connected to the ODU and network terminating equipment using
Cat5e cable with RJ45 connectors. It is also plugged into an AC or DC power supply so that it can
inject Power over Ethernet (POE) into the ODU. Choose one of the following PSUs
•
The AC Power Injector (left) accepts an AC input supply only.
•
The AC+DC Enhanced Power Injector (right) accepts both AC and DC input, tolerates a greater
temperature range, and allows the ODU to support a device on the Aux port, such as a video
camera or wireless access point. It also allows the ODU to provide DC power output.
