LEDs, Switches, and Jumpers 
When adding or removing a component or changing a security feature, the server 
must be reconfigured to recognize these changes. If the system configuration is 
incorrect, the server may not work properly, and you may receive error messages on 
the screen. 
 
IMPORTANT:  Reserved switches are provided for use by authorized service providers only 
and should not be changed from the indicated default settings. 
Refer to Figure E-3 and Table E-3 for location on the system board of the System 
Configuration Switch. 
The following subsections provide reference information about setting the system 
board switches and jumpers, which is part of the reconfiguration process, along with 
running the ROM-Based Setup Utility (RBSU).

The system configuration switch (SW1) is an eight-position switch used for system 
configuration. Refer to the labels attached to the inside of the server access panel for
