Installing Hardware Options 13. Be sure that the LED on the front of the DVD drive is illuminated green, indicating that the system is functioning properly. For detailed information on LEDs, see Appendix C, "System LEDs and Switches." 14. If any of the LEDs indicates an error, see Appendix D, "Troubleshooting," or refer to the troubleshooting guide for instructions. External Devices You can connect external devices in two ways: • To SCSI connector A or B on the system board using the internal-to-external SCSI cable assembly • To a SCSI controller or Smart Array Controller installed in an expansion slot IMPORTANT: The ProLiant ML530 Generation 2 server ships with the drive cages cabled internally to SCSI connectors A and B. If you want to cable a SCSI device to SCSI connector A or B using the internal-to-external SCSI cable assembly, you must first disconnect the appropriate drive cage cable. Once you have disconnected a drive cage cable, you must cable it to a controller board to retain use of that drive cage. For more information on cabling external storage devices, see Chapter 7, "Cabling the Server," or refer to the documentation that ships with the external storage device. Connecting an External Device using the Internal-to-External SCSI Cable Assembly NOTE: The external configuration and external appearance of your server may look different from the following illustrations, depending on your server configuration. To connect an external SCSI device using the internal-to-external SCSI cable assembly: 1. Be sure that the external device can connect to a VHDCI SCSI connector. 2. Power down the server. See "Powering Down the Server" in this chapter. 3. Remove the access panel. See "Removing the Access Panel" in this chapter. HP ProLiant ML530 Generation 2 Server Setup and Installation Guide 3-73
