Static Precautions

An electrostatic discharge (ESD) can damage disk drives, option boards, and other
components. You can provide ESD protection by wearing an antistatic wrist strap
attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent damage, keep
them in their protective packaging when they are not installed in your system.
Standard Configuration
Your system is cabled using a single channel on-board Adaptec 7860 controller and a
single on-board Adaptec 7880 controller. The Adaptec 7860 controller supports the
standard internally mounted CD-ROM.
The Adaptec 7880 contains a SCSI controller that uses a PCI bus master interface.
Internally, the controller is capable of operations using either 8- or 16-bit SCSI
providing 10 MB/s (Fast-10) or 20 MB/s (Fast-20) throughput, or 20 MB/s (Ultra) or 40
MB/s (Ultra-wide) throughput. As implemented on the system board, this controller
attaches to an Ultra-2 SCSI backplane that supports up to seven Ultra-2 SCA drives.
A 3.5-inch diskette drive is also installed in all systems and interfaces separately to the
system board.
Referring to Figure A-1, a 68-pin wide SCSI interface cable (K) is connected to the
SCSI connector (J) in the upper edge of the system board. This cable connects to the
front of the hard disk drive's SCSI backplane (V).
The IDE interface cable is not connected to the IDE connector (U) towards the left edge
of the system board. Instead it is in the accessory box.
Optional internally mounted SCSI removable media devices may be connected to the
SCSI controller connector or optional internally mounted IDE removable media devices
may be connected to the IDE controller connector.
When adding or removing IDE devices, consider the following:
Note:
A-2 System Cabling
Only one IDE cable is supplied with the system.
