3 1/2-inch diskette drive

One location for a 3 1/2-inch removable media device

5 1/4-inch SCSI CD-ROM

Three locations for 5 1/4- inch removable media devices

12 locations for 3 1/2-inch Ultra2 Wide SCSI-2 hard drives

Rail and back panel slots support up to 11 add-in boards (two ISA and nine PCI).

3 1/2-inch diskette drive is externally accessible.

One externally accessible 3 1/2-inch half-height bay is available for server expansion.

5 1/4-inch CD-ROM drive is externally accessible.

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

Three hard disk drive cages; each holding up to four 3 1/2-inch hot- swappable Ultra2 wide SCSI-2 hard drives. Each cage is secured behind a metal EMI door; drives can be swapped in or out of the system without powering it down. The array of drives allows easy setup of RAID applications.

Hot swap-capable	A hot swap-capable backplane is part of each drive cage assembly for
backplane	SCSI hard drives. The backplane is designed for Ultra2 wide SCSI-2
	devices that use the industry standard 80-pin Single Connector Attach
	(SCA) connector. The backplane consists of a row of four drive
	connectors.
Power supply	From two to three 420 Watt autoranging power supplies are easily
	removed/installed for service. In a three-supply system, the third supply is
	redundant.
Software: utilities, setup	BIOS Setup, Resource Configuration Utility, and SCSISelect Utility. The
	EXPRESSBUILDER CD-ROM contains the setup utilities and the ESMPRO
	CD-ROM contains the server management software.
Security	Mechanical: Key lock at the front door. One intrusion sensor for front door
	to secure diskette, hard disk, removable media device, power on/off
	switch, reset switch, top cover, and left/right panel access. Three power
	inter-lock sensors one on each side of the chassis and one on top of the
	chassis. BIOS: Password enable.
