a. To a different slot on the same bus (not applicable for PCI Express) b. To a PCI, PCI-X, or PCI Express slot on a different bus c. To the same slot in another working server of the same or similar design If the board works in any of these slots, either the original slot is bad or the board was not properly seated. Reinsert the board into the original slot to verify. 4. If you are testing a board (or a device that connects to a board): a. Test the board with all other boards removed. b. Test the server with only that board removed. CAUTION: Clearing NVRAM deletes the configuration information. Refer to the server documentation for complete instructions before performing this operation or data loss could occur. 5. Clearing NVRAM can resolve various problems. Clear the NVRAM, but do not use the backup .SCI file if prompted. Have available any .CFG, .OVL, or .PCF files that are required. Internal system problems CD-ROM and DVD drive problems System does not boot from the drive Action: 1. Be sure the drive boot order in RBSU is set so that the server boots from the CD-ROM drive first. 2. If the CD-ROM drive jumpers are set to CS (the factory default), be sure the CD-ROM drive is installed as device 0 on the cable so that it is in position for the server to boot from the drive. 3. Be sure no loose connections (on page 17) exist. 4. Be sure the media from which you are attempting to boot is not damaged and is a bootable CD. 5. If attempting to boot from a USB CD-ROM drive: o Refer to the operating system and server documentation to be sure both support booting from a USB CD-ROM drive. o Be sure legacy support for a USB CD-ROM drive is enabled in RBSU. Data read from the drive is inconsistent, or drive cannot read data Action: 1. Clean the drive and media. 2. If a paper or plastic label has been applied to the surface of the CD or DVD in use, remove the label and any adhesive residue. 3. Be sure the inserted CD or DVD format is valid for the drive. For example, be sure you are not inserting a DVD into a drive that only supports CDs. Hardware problems 40
