Figure 2-9. SCSI-2 Hard Drive Bays
Three hard drive cages
(EMI panel and exterior door
shown open)
The backplane has two main functions: SCSI drive
control and system data logging. Drive status is
monitored to detect failing drives and to control LED
indicators. The backplane features are:
■
Inserting and removing of hard drives while power
is on (referred to as “hot swap”)
■
Simplified cable management
■
SCA connectors to simplify inserting and removing
hard drives
■
SCSI management of fault LEDs.
Each backplane supports SCSI drives with SCA
connectors.
