Overview 1.
Overview 1.3 Hardware You can install the Intel® SRCU41L Raid Controller in a computer with a mainboard that has 5 V or 3.3 V, 32- or 64-bit PCI slots. The following subsection describes the hardware configuration feature. 1.3.1 Table 1.
Hardware Installation 2 This chapter describes the procedures used to install the Intel® Raid Controller SRCU41L. It contains the following sections: • • • • 2.1 Section 2.1, “Requirements” on page 5 Section 2.2, “Quick Installation” on page 5 Section 2.3, “Detailed Installation” on page 6 Section 2.
Hardware Installation 6. Turn power on after completing the safety check. 2.3 Detailed Installation This section provides detailed instructions for installing a Intel® Raid Controller SRCU41L. 1. Unpack the Storage Adapter Unpack and remove the Intel® Raid Controller SRCU41L. Inspect it for damage. If it appears damaged, or if any items listed below are missing, contact your Intel support representative.
Hardware Installation Figure 2. Install the Battery Backup Unit A B C 3. Power Down the System Turn off the computer and remove the AC power cord. Remove the system’s cover. See the system documentation for instructions. 4. Check the jumpers. Ensure that the jumper settings on the your Intel® Raid Controller SRCU41L are correct. See Chapter 3, “Storage Adapter Characteristics” for diagrams of the Intel® Raid Controller SRCU41Ls with their jumpers and connectors. 5.
Hardware Installation Select a PCI slot and align the Intel® Raid Controller SRCU41L PCI bus connector to the slot. Press down gently but firmly to ensure that the card is properly seated in the slot, as shown in Figure 3. Then screw the bracket into the computer chassis. Figure 3.

Hardware Installation 7. Connect SCSI Devices to the Storage Adapter Use SCSI cables to connect SCSI devices to the Intel® Raid Controller SRCU41L. To connect the SCSI devices a. Disable termination on any SCSI device that does not sit at the end of the SCSI bus. b. Configure all SCSI devices to supply TERMPWR. c. Connect cables to the SCSI devices. See the following table for maximum cable lengths. Device Cable Length in Meters Fast SCSI (10 Mbytes/s) 3 SE SCSI 3 Ultra SCSI 1.

Power On Host System Replace the computer cover, and reconnect the AC power cords. Turn power on to the host computer. Ensure that the SCSI devices are powered up at the same time as, or before, the host computer.
Hardware Installation If you want to run the Intel® Raid Controller SRCU41L Configuration utility or BIOS Console at this point, press the appropriate keys when this message appears: Press for WebBIOS 2.3.1 Resolving a Configuration Mismatch If the replacement controller has a previous configuration, a message displays during the power-on self test (POST) stating that there is a configuration mismatch.

Storage Adapter Characteristics 3.1.2 Decoding the Audible Alarm The following beep codes are used on Intel RAID controllers that use software stack 2. Thesecodes usually indicate a drive has failed: • Degraded Array: Short tone, one second on, one second off • Failed Array: Long tone, three seconds on, one second off • Hot Spare Commissioned: Short tone, one second on, three seconds off These drive failure tones will repeat until the problem is corrected or until the alarm issilenced or disabled.

Storage Adapter Characteristics 3.3.6 Safety Characteristics The Intel® Raid Controller SRCU41L meets or exceeds the requirements of UL flammability rating 94 V0. Each bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. For the boards installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
Glossary of Terms and Abbreviations A Figure 6. Glossary of Terms and Abbreviations Term Active Termination BIOS Definition The electrical connection required at each end of the SCSI bus, composed of active voltage regulation and a set of termination resistors. Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, and Ultra320 SCSI require active termination. Basic Input/Output System. Software that provides basic read/write capability. Usually kept as firmware (ROM based).
Glossary of Terms and Abbreviations Figure 6. Glossary of Terms and Abbreviations Term SCSI Device SCSI ID Definition Any device that conforms to the SCSI standard and is attached to the SCSI bus by a SCSI cable. This includes SCSI storage adapters (host adapters) and SCSI peripherals. A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15 for Wide SCSI).
