Replacement Note: To install 
two drives in the U-shaped 
carrier, install the first 
drive in the bottom of the 
carrier. Then place the 
second drive in the carrierÕs 
upper bay and attach screws 
through the sides of the 
carrier into the sides of the 
drive. Note that tightening 
screws on the left side of the 
carrier bends the arms of

Hard Drive, Ultra2 
LVD SCSI
Before you begin, open the 
right side access panel.
Note: This computer 
supports a total of three 
internal hard drives. If a 
unit has at least one internal 
Ultra2 LVD SCSI drive, an

and a SCSI data cable, you 
can connect additional 
internal and external Ultra2 
LVD SCSI devices. The unitÕs 
SCSI data cable supports 
three internal SCSI drives;

this cable has a built-in 
terminator so you donÕt need 
to add one. You can connect 
external Ultra2 LVD SCSI 
devices to the port on the 
rear of the computer.
If the computer came with 
one Ultra2 LVD SCSI drive, 
itÕs installed in drive bay 1, 
near the front of the 
computer. If it came with 
two drives, the second one is 
installed in bay 2. If a third 
drive is installed, itÕs in bay 
3. Usually the computer 
uses the drive in bay 1 to 
start up.

factory-installed drive has 
ID 0; a second factory-
installed drive has ID 1; a 
third drive has ID 2. The 
SCSI PCI card has ID 7.
