The PSR1400-D power module provides system power and PoE power. The switch marked “SYSTEM” 

is used to control the system power, and the other marked “PoE” is used to control the PoE power. The 

RJ-45 port (RS485) on the right of the PoE power switch is the COM port for monitoring PoE.  

On the right of the panel are the input LED, output LED, fan LED and PoE LED. For their colors and 

descriptions, refer to section 7.2.4  “Troubleshooting PSR1400-D.”
