4.1 POE Switch Requirements
SMN-890 is a POE powered device. SMN-890 consists of IR transmit
module which its IR transmission power is configurable. The IR
transmission power will affect the SMN-890 power consumption. Below
table shows the requirements needed for a POE switch which uses to
power up the SMN-890.
