Prior to installing the drive in the system, (1) the interface board is connected to the back of the
drive and secured with two 8mm screws. The drive is then installed in the drive carrier metal
housing by holding the left side of the drive carrier in the left hand, and with the right hand
installing the right side of the drive into the right side of the drive carrier, (2) making sure to line
up the two holes in the right side of the drive with the two mounting tabs on the right side of the
drive carrier. Then, while flexing the left side of the drive carrier slightly down, (3) insert the left
side of the drive into the drive carrier, making sure to line up the two holes on the left side of the
drive with the two mounting tabs on the left side of the drive carrier. If this is done correctly, the
drive carrier will be flush with the bottom and sides of the drive, and all four mounting tabs will
be installed in the mounting holes on the drive. Observe that the right side mounting tabs are
correctly inserted into the right side mounting holes on the drive by looking at the right bottom of
the drive carrier assembly. Observe that the left side mounting tabs are correctly inserted into
the left side mounting holes on the drive by looking at the top left of the drive carrier assembly.
2.4.3.2 Hard
Drive
Bays
There are two hot-plug SCSI SCA hard drive bays in the system (see (1) and (2) in the drawing
below). Each hard drive bay supports a U320 SCA (single connector attach) SCSI disk drive
mounted in a drive tray. The drive tray is installed into the front of the chassis in the hard drive
bay, and then secured in place by latching the handle on the drive tray. Ultra 320 SCSI
technology (SCA interconnect) or slower hard disk drives can be installed in the hard drive bays.
The hard drive bays are designed to accept 15,000 rotations per minute (RPM) hard drives (and
below) that consume up to 18 W of power.
The SCSI ID for each hard drive position is hardwired on the midplane board, so the use of
jumper(s) to select a unique SCSI ID is not necessary. Hard disk drive position 1 is hardwired
to SCSI ID 0 on the SCSI bus and hard disk drive position 2 is hardwired to SCSI ID 1 on the
SCSI bus.
