Description
The FPGA power LED helps to identify
different FPGA errors.
• LED blinking rapidly (four times per
second): The FPGA permission is
delayed.
• LED blinking slowly (once per
second): The FPGA is ready to power
on.
• LED on: The FPGA power is on.
The XCC heartbeat LED helps to identify
the XCC status.
• Blinking (about one flash per second) :
XCC is working normally.
• Blinking at other speeds or always on:
XCC is at the initial phase or is working
abnormally.
• Off: XCC is not working.
Action
If FPGA power status LED is always
blinking rapidly over 5 minutes, do the
following:
• If XCC can be accessed:
1. Check the Lenovo XClarity
Controller event log and the system
error log for information about the
error.
2. Save the log if necessary, and clear
the log afterwards.
• If XCC cannot be accessed:
1. Re-plug the power cord.
2. Check and ensure that the system
board is installed correctly. (Trained
technician only) Reinstall it if
needed.
3. If the problem remains, contact

2. Check and ensure that the system
board is installed correctly. (Trained
technician only) Reinstall it if
needed.
