There are two LED's at the bottom of the RJ-45 connector:

•
Device Identify: Blinking green
The identify function is turned on from a remote computer using the web page or a SCPI
command. The front panel blinks along with the rear. It is used to identify one power supply
in a rack of instruments. The blinking is turned off by the web page, by sending another
SCPI command, or by changing any front panel control. In a multi-drop chain, only the
master LAN supply blinks.
• LAN Fault: Steady red
Shows the LAN mode is not enabled, the LAN connection was never made, or that the LAN
connection was made and then broken.
