5 System status
LED (green)
The system status LED indicates
the working status of the system.
• Fast blinking (about four
flashes per second): Power
fault or waiting for XCC power
permission ready

• If the system status LED is blinking fast over 5 minutes
and cannot power on, check the XCC heartbeat LED
and follow the
actions for the XCC heartbeat LED.
• If the system status LED remains off or is blinking fast
(about four flashes per second) and the system error
LED on the front panel is on (yellow), the system is in a
power fault status. Do the following:
1. Re-plug the power cord.
2. Remove installed adapters/devices, one at a time,
until you reach the minimal configuration for
debugging.
3. (Trained technician only) If the problem remains,
capture FFDC log, and replace the processor
