Chapter 7 – Fault Tracing
Hardware Failures
7-6
The NMBP-01 module has a combined power and Watchdog LED. This LED
is normally on. If the built-in watchdog ' kicks in' , the power LED will go
dim for half a second, and the NMBP-01 module will restart itself.
This restart can be caused by:
• Module failure. In this case the NMBP-01 Status LED will flash according
to error code 2. This is the only non-normal condition
• Pressing the configure button
• Loss of drive power
• Loss of fibre link connection between the NMBP-01 and the ACS 600
drive.
