The following sections give an overview of the systems. Differences between systems are
noted as they occur.
SYSTEM CHASSIS
The chassis provides an enclosure for system controls, system board, power supply, five
expansion board slots, a six-connector PCI/ISA backboard, and six storage device slots.
The PCI/ISA backboard has three 8-/16-bit ISA connectors and three 32-bit PCI
connectors. Two ISA connectors and two PCI connectors are dedicated. The remaining
ISA and PCI connectors are shared, meaning their usage is limited to one or the other but
not both.
The six storage device slots support up to four accessible devices and two internal hard disk
drive devices. The four accessible devices include the standard one-inch high 3 1/2-inch
1.44-MB diskette drive, a standard CD-ROM reader, and, in some 2516 models, an Iomega
100i Zip drive. One of the two internal drive slots holds the standard 1-inch high 3 1/2-inch
hard disk drive. The other internal drive slot is for an optional 1-inch high 3 1/2-inch hard
disk drive.
