Installation 13
10. Replace any expansion boards that may have been removed earlier. Replace the
system cover according to the manufacturer’s instructions.
11. Reconnect any system or peripheral cables removed earlier.
12. If the DE75i-S has been installed into an external expansion chassis, connect the SCSI
and power cables to the chassis. If the expansion chassis is at the end of a daisy
chain, make certain that it is properly terminated. Refer to the computer system and
expansion chassis manuals for information on how to do this. Turn on the expansion
chassis power before turning on the computer system power.
13. Turn ON power to the computer. If the installation has been successful, and all cables
have been properly attached, the system should boot normally. Although the
computer may not recognize the DE75i-S yet, the appropriate front panel LED
indicators on the Data Express should illuminate. If the system does not boot properly,
there could be a SCSI ID conflict. Refer to the following section "Selecting the Unit
Number" for further information.
NOTE: The lock on the DE75i-S receiving frame functions as a lock and a DC power
switch for the carrier unit. The lock must be engaged (turned counterclockwise)
in order to supply power to the carrier and installed drive unit.
14. The new drive may need to be formatted or initialized prior to use with the operating
system and applications software. Additionally, an appropriate driver may need to
be installed for the host controller to recognize the newly installed device. Refer to
the drive and/or computer manufacturer's documentation for formatting information.
Refer to the host controller instructions for driver information.
Selecting the Unit ID Number
Each SCSI device on the computer system requires a separate SCSI ID number.
8-bit SCSI interface protocol permits 8 (0-7) unique SCSI ID numbers. Usually, ID7 is reserved
for the host controller. If the computer system has any internal or external SCSI devices, some
ID numbers may already be reserved. For instance, if the computer system is already equipped
with an internal SCSI hard drive, the drive may be designated as SCSI device "0". Refer to
the computer system documentation for additional information.
1. Verify that power is turned ON to the DE75i-S receiving frame by turning on the
computer or external expansion chassis. A number should appear in the unit ID display
window if the carrier is locked into place.
