Rail and back panel slots support up to 10 add-in boards (four EISA and six PCI).

3 ½-inch diskette drive is externally accessible.

One externally accessible 3 ½-inch half-height bay is available.

The hard disk drive bay can hold six 3 ½-inch hot- swappable ultra wide SCSI-2 hard drives. The bay is secured behind a lockable metal EMI door; drives can be swapped in or out of the system without powering it down, if a Redundant Array of Independent Disks (RAID) controller module is installed. The array of drives allows easy setup of optional RAID applications.

A hot swap-capable backplane is part of each 3 ½-inch drive bay assembly for SCSI drives. The backplane is designed for wide ultra SCSI-2 devices that use the industry standard 80-pin Single Connector Attach (SCA) connector. The backplane consists of two rows of three drive connectors.

Three externally accessible 5 1/4-inch half-height bays are available for diskette, CD-ROM, and/or tape drives.

From two to three 330 Watt autoranging power supplies are easily removed/installed for service. In a three- supply system, the third supply is redundant.

Each power supply has two integral cooling fans. Six more fans provide cooling for boards and drives.
