Troubleshooting BMC
Heartbeat LED Indicator
The Heartbeat LED (CR1, which location is near the “Aspeed” chipset) is used to indicate whether the
BMC work normally or not. When BMC firmware works normally, it should blink with one second
interval. Otherwise, the BMC firmware should be in ill.
When encounter this failure, you should remove the server power and reboot the server (unplug the
server power cable, and then plug it again) to let BMC reboot. If the heartbeat LED still works
abnormally after server power on, you can attempt to flash the latest BMC firmware via the method
“Update BMC Firmware under DOS mode
, Windows, Linux”.
