The Compaq AlphaStation XP1000 System enclosure contains a total of six bays in the following two storage areas:
Front-Accessible Area. The front-accessible area contains four bays; one 3.5-inch low-profile bay for a 1.44 MB diskette drive and three 5.25-inch by 1.6-inch bays. Typically, the CD-ROM drive is installed in the lower bay of this area. The 5.25-inch bays support 3.5-inch drives when expansion brackets are used on the drives.
At the time of publication, some drives generate too much heat during normal operation to allow installation into the internal drive bays; they may be installed in the top front-accessible drive bay only (to accomodate the necessary twin fan module and its cable). Other large non-accessible drives (which do not require the fan module) may be located in any slot in the Front-Accessible Area at your discretion.
Internal Area. The internal storage area contains two bays; both supporting 3.5-inch by 1.0-inch drives. Typically, the system's first hard disk is installed in the lower bay of this area.
Note: Some large hard disk drives generate enough heat during normal operation to require a twin fan module to be installed in conjunction with them. Use the top front-accessible drive bay for such drives and their twin fan modules.
The front view shows the location of the front-accessible drive bays, and the internal view illustrates the location of the internal drive bay cage.
