Verifying component failure
Before replacing the controller, cache module, or battery pack:
•
Check the controller LCD display panel for error messages.
•
Record any failure LEDs or LCD panel messages for reference purposes.
•
Check the controller heartbeat LED (
1
) . If the LED is not blinking, it might indicate a failure.
•
Check the controller fault LED (
2
) . If the LED is on, it might indicate a failure.
