- Page 8 This guide is the hardware reference and user’s guide for the Intel RAID Controller SRCU42X. It contains complete installation instructions and specifications . For information about how to configure the SRCU42X controller, and for an overview of the software drivers, see the Intel RAID Software User’s Guide. Audience This document assumes that you have some familiarity with RAID controllers and related support devices.
- Page 9 When Working Inside Your Computer Notice: Do not attempt to service the computer system yourself, except as explained in this guide and elsewhere in Intel documentation. Always follow installation and service instructions closely. 1. Turn off your computer and any peripherals.
- Page 10 Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface, such as the metal around the card-slot openings at the back of the computer.

Page 15: Overview
SE with LVD devices, or the bus speed will be limited to the slower SE (Ultra SCSI) SCSI data transfer rates. Do not connect a high voltage differential (HVD) device to the SCSI bus because the chip on the SRCU42X controller must be reset to return to LVD or SE mode once the HVD device is removed. -

Support for up to 1 Gbyte of double data rate (DDR) SDRAM; a 32-, 64-, 128-, 256, or 512-Mbyte, or 1-Gbyte DIMM can be installed. • Support for a 64-bit PCI host interface (note that the SRCU42X is a PCI-X controller) • The SRCU42X controller has two internal and two external SCSI connectors •... -
Page 17: Hardware
Hardware You can install the SRCU42X controller in a computer with a motherboard that has 3.3 V, 64-bit PCI-X slots. The following subsections describe the hardware configuration and configuration-on-disk. 1.3.1 Storage Adapter Configurations Table 1-1 describes the features for the Intel RAID Controller SRCU42X. -
Page 18: Configuration On Disk
Configuration on Disk Configuration on Disk saves configuration information both in NVRAM on the Intel RAID Controller SRCU42X and on the disk drives attached to the SRCU42X controller. If the SRCU42X controller is replaced, the new SRCU42X controller detects the actual RAID configuration from the configuration information on the drives. -

5) Install the Intel RAID SRCU42X Adapter Select a 3.3 V PCI or PCI-X slot, and align the SRCU42X controller 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 2.2. - Page 22 For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. An easy way to do this is to connect the SRCU42X controller to one end of the SCSI cable and to connect an external terminator module at the other end of the cable.

During boot, a BIOS message appears. The firmware takes several seconds to initialize. During this time, the SRCU42X controller scans the SCSI channel(s). The BIOS Configuration utility prompt times out after several seconds. The second portion of the BIOS message displays the Intel RAID Controller SRCU42X number, firmware version, and cache SDRAM size. -
