Table 3-1Intel RAID Controller SRCZCRX Headers and Connectors (Cont.) Connector Description Type Comments J3 Universal Asynchronous 3-pin connector Reserved Receiver/Transmitter (UART) debugging J4 Mode select 2-pin connector Reserved J5 Clear NVRAM 2-pin connector Used to clear the contents of the non-volatile random access memory (RAM) J6 Write-pending Indicator (dirty 2-pin header Connector for an LED mounted on cache) LED the system enclosure. THe LED indicate when data in the cache has not been written to the storage devices. J7 Onboard BIOS disabled 2-pin header Disables the BIOS so it will not run on the firmware. When no jumper is installed (default), the BIOS is enabled. When jumpered, the BIOS is disabled. J8 Serial EEPROM 2-pin connector Provides board information, such as the serial number, OEM number, revision number, and manufacturing data, eliminating the need to open the server chassis to obtain this board information. J9 Non-maskable interrupt (NMI) 2-pin connector Reserved 3.2 Intel RAID Controller SRCZCRX Characteristics The SRCZCRX controller ensures data integrity by intelligently validating the compatibility of the SCSI domain. The storage adapter uses Fusion-MPT architecture that allows for thinner drivers and better performance. Table 3-2 shows the general characteristics for the SRCZCRX controller.
