Status LEDs
The three Status LEDs indicate the current operating status of the HP Rack
Storage/12.
Bezel
The bezel covers the chassis, the support rails, and the thumbscrews securing the
chassis to the support rails. The bezel clips on to the chassis and can be installed
and removed without tools.
Drive Cage
The drive cage supports the installation of 8 half-height hard drives, 12
low-profile hard drives or a combination of half-height and low profile hard
drives. Drive spacers are used between half-height and low-profile hard drives.
Filler panels in unused drive slots are mandatory to maintain proper drive
cooling.
Configurations
Internal chassis braces divide the drive cage into four sections. Each section can
support the following hard drive configurations (see Figure 1-1):
•
Three low-profile hard drives
•
Two half-height hard drives
•
One low-profile drive, one half-height drive and one drive spacer
SCSI Channels
Two internal SCSI channels connect the hard drives to the RS/12 SCSI card.
Hard drives installed in the left-half of the drive cage are connected to Channel 1.
The hard drives installed in the right-half of the drive cage are connected to
Channel 2 (see Figure 1-2).
