Important: Regardless of how many SCSI drives are installed,
all four drive carriers must remain in the drive bays to main-
tain proper airflow.
Use caution when working around the SCSI backplane. Do not
touch the backplane with any metal objects and make sure no
ribbon cables touch the backplane or obstruct the holes, which
aid in proper airflow.

2. Installing/removing hot-swap SCSI drives
Four SCSI drive bays are located in the front of the chassis, making them
easily accessible for installation and removal. These SCSI drives are hot-
swap units, meaning they can be installed and removed without powering
down the system. To remove, first push the release button located
beside the drive LEDs, then swing the handle fully out and use it to pull the
unit straight out.
SCA Backplane
The SCSI drives plug into an SCA backplane that provides power, SCSI ID and
bus termination. A RAID controller can be used with the SCA backplane to
provide data security. The operating system you use must have RAID support
to enable the hot-swap capability of the SCSI drives. The SCA SCSI backplane
is already preconfigured, so there are no jumpers or switches present on it.
