Installing Hardware Options 
When installing ATA hard drives in the server, observe the following general 
guidelines:  
• 
• 
• 
• 
Do not add more than two ATA devices per channel. 
Always populate hard drive bays starting with the lowest ATA device number. 
Configure ATA hard drives through the Cable-Select mode. 
Set the jumpers on both ATA drives to Cable-Select mode. Doing so enables the 
ATA cable to set a unique address, such as Device 0 or Device 1, for each hard 
drive. 
 
 
CAUTION:  Installing unsupported hard drives may damage the system by 
consuming power and generating heat in excess of the server’s operating tolerance. 
This condition may result in a loss of system and/or data integrity. 
 
 
CAUTION:  When supporting a mixed environment of ATA drives and SCSI drives in 
the server, the ATA drive must be the boot device. 
ATA hard drives installed in the server appear as Devices 0 and 1, from left to right 
when viewed from the front of the server. Refer to Figure 3-21.
