Clearing CMOS
To erase an invalid system configuration:
1. Move the S6 configuration switch (SW1) to the On position. This setting clears portions of
CMOS and NVRAM.
2. Power up the server. Wait for the ProLiant logo to display on the video display.
3. Power down the server.
4. Move the S6 configuration switch to the Off position.
5. Power up the server. Refer to the Compaq ProLiant ML570 Server Troubleshooting Guide
for more information.
To clear all contents of CMOS NVRAM, remove the battery, then reinstall the battery. All
device settings have to be completely reconfigured. See Figure 4-5 for the configuration
switchbank location and Table 4-5 for the configuration settings.
