Basic hardware procedures
4.1.2 Determining the error class
The Local Service Concept (LSC) allows you to identify defective server
components. Failure events are assigned to one of two error classes:
– Global Error events that need to be resolved by maintenance personnel
– Customer Self Service (CSS) error events that may be resolved by
operating personnel
Global Error and CSS LEDs indicate, if the defective component is a customer
replaceable unit or if maintenance personnel needs to be dispatched to replace
the part.
I The indicators also light up in standby mode and after a server restart
due to a power failure.
