SCSI signal cable Cable clamp 15. Connect the tape-drive power cable to the tape-drive power connector, J100 (see "System-board internal cable connectors" on page 19 for the location of the power connector). 16. Replace the hard disk drive backplane signal cable, making sure that it passes through the cable clamp on top of the SCSI signal cable. Close the cable clamp. 17. Reconnect the hard disk drive backplane signal cable to the connector on the system board. 18. Reinstall the DIMM air baffle. Make sure that it clicks into place. You might have to apply extra downward pressure to make sure that it is securely in place. 19. Connect the SCSI signal cable to the connector on the SCSI adapter in slot 1 of the riser-card assembly. 20. Install the riser-card assembly. Arrange the excess length of the SCSI signal cable to avoid blocking airflow to the heat sink in the area. Chapter 2. Installing optional devices 57
