This document updates information on the following topics for your Dell PowerEdge 2450 system: Installing and removing expansion cards Small computer system interface (SCSI) hard-disk drive support Installing an upgrade microprocessor in PowerEdge 2450 systems To install an expansion card, perform the following steps.
securing lever expansion-card cage 4. Locate the expansion-card cage securing lever (see Figure 1-1). Rotate the lever upward until it stops in an upright position. 5. Lift the expansion-card cage up and away from the chassis. 6. Open the expansion-card latch (see Figure 1-2) and remove the filler bracket from the expansion slot.
7. Install the new expansion card. Position the expansion-card cage so that the riser board lies horizontally on your work surface. Insert the card-edge connector firmly into the expansion-card connector on the riser board, until the card is fully seated. 8. When the card is seated in the connector and the card-mounting bracket is aligned with the brackets on either side of it, close the expansion-card latch. 9.
Your system’s integrated SCSI host adapter supports the Ultra3 (also known as Ultra160) SCSI standard as defined by the SCSI Trade Association. The Ultra3 SCSI standard supports a combination of new SCSI performance and manageability enhancements to increase data throughput up to 160 megabytes per second (MB/sec). For specific information about the Ultra3 SCSI standard, see the SCSI Trade Association Web site at http://www.scsita.org.
2. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the system, before touching anything inside your system. While you work, periodically touch an unpainted metal surface on the system chassis to dissipate any static electricity that might harm internal components. 3. Disconnect your system and devices from their power sources. Also, disconnect any telephone or telecommunication lines from the system.
View the system configuration screens in the System Setup program and make a record of the settings. If an ESM firmware diskette is included with the upgrade kit, update your ESM firmware with the version contained on that diskette by performing the following steps. The latest version of the ESM firmware is available at http://support.dell.com. 1. Insert the ESM firmware diskette into the diskette drive. 2. Reboot the system. 3.
