console breakout cable if it is defective.
Keyboard problems:
Make sure that all cables and the console breakout cable are properly connected and secure.

Intermittent unexpected reboots
Note:
Some uncorrectable errors require that the server reboot so that it can disable a device, such as a
memory DIMM or a processor to allow the machine to boot up properly.
1. If the reset occurs during POST and the POST watchdog timer is enabled, make sure that sufficient time
is allowed in the watchdog timeout value (POST Watchdog Timer).
To check the POST watchdog time, restart the server and press the key according to the on-screen
instructions to display the LXPM system setup interface. (For more information, see the “Startup”
section in the LXPM documentation compatible with your server at
https://sysmgt.lenovofiles.com/help/

.
2. If the reset occurs after the operating system starts, do one of the followings:
• Enter the operating system when the system operates normally and set up operating system kernel
dump process (Windows and Linux base operating systems will be using different method). Enter the
UEFI setup menus and disable the feature, or disable it with the following OneCli command.
OneCli.exe config set SystemRecovery.RebootSystemOnNMI Disable --bmc XCC_USER:XCC_PASSWORD@XCC_IPAddress
• Disable any automatic server restart (ASR) utilities, such as the Automatic Server Restart IPMI
Application for Windows, or any ASR devices that are installed.
3. See the management controller event log to check for an event code that indicates a reboot. See “Event
logs” on page 137 for information about viewing the event log. If you are using Linux base operating
system, then capture all logs back to Lenovo support for further investigation.
