Installing or Replacing Parts
NOTE: The Disk Activity LED automatically communicates with IDE and SCSI drives
connected to the built-in controllers.
To get this functionality with an SCSI or IDE controller card, connect the card with an LED
activity cable to the hard drive activity LED connector on the system board.
Refer to “System Board Components and Connectors” on page 3-4 for a picture showing where
on the system board to connect the LED activity cable (item 36).
External SCSI Devices
You can add an external SCSI connector (U320 SCSI port) to the on-board SCSI controller or to
an optional PCI SCSI controller card.
Note that:
■
You can connect up to 15 devices at any SCSI ID, except SCSI ID 7 which is used by the host
controller.
■
The bus should be terminated as normal if you use external devices. No termination is
necessary if there are no devices connected.
■
SCSI IDs are set by jumpering pins on the disk drive.
■
If you are adding a SCSI hard drive to your system, you may need to change the SCSI ID of
the new hard drive so that all SCSI devices have unique IDs. If two devices use ID 0, the
system will not boot.
■
If you are replacing a SCSI hard drive, you can use the SCSI ID number of the current hard
drive for the replacement hard drive.
To install the external connector:
1. Remove the knockout panel in the chassis using a regular screwdriver. Insert a flat-head
screwdriver into the rectangular hole and twist the metal until the panel comes out.
