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.
4.1.2.1 Global Error indicator
Ê Check the Global Error indicator on the front or connector panel of the 
server.
Ê For further diagnostics, proceed as follows: 
– Hardware errors:
Check the System Event Log (SEL) as described in section "Viewing the 
SEL" on page 81.
– Software / agent related errors:
Check the ServerView System Monitor, available on Windows or Linux 
based servers with ServerView agents installed.
I For further information, please refer to the "ServerView System 
Monitor" user guide.
