Without the left control panel (LCP), the server can POST but displays an error stating "Liquid Cooling setting capable system" and then continue booting to the operating system.
When checked against the Dell order there is no Liquid cooling component on the server that is reported with this alert.
Cause
The left control panel (LCP) component contains the information whether the system config is configured with Liquid cooling.
If this component causes no POST due to a fault and removed OR it is faulty, it might cause the alert above to be displayed during POST.
Customer can still press F1 during POST to continue booting the OS. This is expected behavior when the LCP is removed from the system for R750 is capable of liquid cooling.
