Table 2-1: LED Status
2.5.2.2. EMX3-FR and EMX6-FR
Each power supply has two status indicator LEDs. The green PSU STATUS LED indicates the health of
the local power supply and its fans. The green PSU STATUS LED will be On under normal conditions.
The FRAME STATUS LED indicates the health of the entire frame and is operated by the frame status
bus of the frame. The red FRAME STATUS LED will be Off under normal conditions and On when there
are Frame Status Fault conditions.
If one of the power supplies malfunctions, (power cord disconnected, power switch is off, fuse is blown,
rear fan is stopped, etc,) then its green PSU STATUS LED will go Off, and the red FRAME STATUS LED
on both power supplies will turn On and the Frame Status fault will be signaled to the Frame status buss.
The PSU STATUS LED on the power supply that is functioning will remain On.
