Packard Bell MH4000 manual Configuration Constraints

2-3

■System board has four EISA slots and six PCI slots for add-in boards. The system board also has a riser board for external I/O (serial, parallel, video) interfaces.

■Chassis can hold 11 drives: 6 hot-swap bays for 3 1/2-inch ultra wide SCSI-2 hard drives; three

5 1/4-inch half-height bays for removable media drives with a CD-ROM reader already installed in one bay; and two 3 1/2-inch half-height bays with a diskette drive already installed in one bay.

■Chassis supports up to three power supplies. The third power supply can be added to provide redundant power.

Configuration Constraints

Power supplies are hot-swappable and are easily removed and installed. The third optional power supply provides redundant power so that if one of the three power supplies fail, the system will continue to operate and the failed power supply can be hot swapped. That is, the failed power supply is removed and replaced without turning power off.

The system has three 5 1/4-inch half-height bays accessible from the front. These bays are convenient for diskette, tape, and CD-ROM drives (removable media). Because of the EMI generated by hard drives, the increased susceptibility to ESD, and cooling requirements, hard drives should not be installed in the 5 1/4-inch half-height bays.
