Control/indicator Function
1 PWR GOOD LED
When lit (green), all DC outputs and the AC input are
within operational limits.
2 FAULT LED
When lit (yellow), one or all of the DC outputs or the
AC input is not within operational limits. This can be an
indication that the module power cord is not fully seated
into a power receptacle at either end, or that the main
library power switch is off.
Power distribution unit
NOTE:
The EML 71e does not include a power distribution unit because you install it in your own rack.
