Does the POWER LED come on when system power is turned on? If not:
– AC—check to ensure that the AC power cord is plugged in to the power supply and the power
source (wall or power strip).
DC—verify that the –48 and +48-V leads are correctly attached to the power supply.
–
– Verify that the system is properly grounded.
– Ensure that the voltage selection switch is in the appropriate AC or DC position.
