The following are some important points to remember when connecting power and signal cables to internal drives: The diskette drive, hard disk drive, and CD-ROM drive that are preinstalled in your server come with power and signal cables attached. If you replace any drives, it is important to remember which cable is attached to which drive. When you install a drive, ensure that the connector at the end of the signal cable is connected to the system board. If two IDE devices are used on a single cable, one must be designated as the primary or master device and the other a secondary or subordinate device; otherwise, some of the IDE devices might not be recognized by the system. The primary or secondary designation is determined by switch or jumper settings on each IDE device. In this server, the CD-ROM drive is the primary device. If you install a second IDE device, it must be the secondary device. To attach an external SCSI drive, you must install an appropriate adapter in the server.
