Switch 3, 4, 7, 8, 9, 10, 11, 12 Default - Function Reserved When the system maintenance switch position 6 is set to the On position, the system is prepared to erase all system configuration settings from both CMOS and NVRAM. CAUTION: Clearing CMOS and/or NVRAM deletes configuration information. Be sure to properly configure the server or data loss could occur. NMI header The NMI header enables administrators to perform a memory dump before performing a hard reset. Crash dump analysis is an essential part of eliminating potential reliability issues, such as hangs or crashes in operating systems, device drivers, and applications. Many crashes can freeze a system, requiring you to perform a hard reset. Resetting the system erases any information that supports root cause analysis. Systems running Microsoft® Windows® experience a blue-screen trap when the OS crashes. When this happens, Microsoft® recommends that system administrators perform an NMI event by temporarily shorting the NMI header with a jumper. The NMI event enables a hung system to become responsive again. For additional information, see the HP website (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00797875/c00797875.pdf). Drive numbering In an 8-bay drive cage, when only one SATA cable is connected, the server can only support a 4-drive configuration. In this configuration, drive bays 1 through 4 are populated, while drive bays 5 through 8 have drive blanks. When the two-port SATA cable option ("Two-port SATA cable" on page 43) is connected, the server supports a 6-drive configuration. In this configuration, drive bays 1 through 6 are populated, while drive bays 7 and 8 have drive blanks. • 8-bay SFF drive model • 8-bay LFF drive model Component identification 14
