3 Open the system. See "Opening the System" on page 48.
4 If applicable, disconnect the cables from the SAS RAID controller daughter card or expansion card and
pull the cables out of the way of the center fans. See "Removing the SAS RAID Controller Daughter
Card" on page 96.
5 Remove the fans from the center fan bracket. See "Removing and Installing a Fan" on page 53.
6 Remove the center fan bracket. See "Removing the Center Fan Bracket" on page 82.
7 Unpack the tape drive (and controller card, if applicable) and configure the tape drive according to
the documentation that came with the tape drive, based on the following guidelines:
Each device attached to a SCSI host adapter must have a unique SCSI ID number. (Narrow SCSI
a
devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15). Set the drive's SCSI ID to avoid
conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the
documentation provided with the drive.
NOTE:
There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to
the cable in order by ID number.
SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that
b
all devices in between be unterminated. Therefore, you enable the tape drive's termination if it is
the last device in a chain of devices (or sole device) connected to the SCSI controller.
8 If a controller card was included in the drive kit, install the card now. See "Installing an Expansion
Card" on page 57.
9 Remove the filler plate from the tape backup unit bay, if applicable:
Push the spring latch at the top of the peripheral bay to the right, and pry the top end of the filler
a
plate away from the system.
Draw the filler plate upward and out of the system.
b
NOTE:
For a full-height tape backup unit, you must remove two filler plates.
10 If the mounting screws are not attached to the drive, install them now.
11 Insert the new tape drive three-quarters of the way into the drive slot on the peripheral bay, with the
mounting screws entering the bay slide slots.
12 Connect the SCSI interface cable in the drive kit to the drive. See Figure 3-15.
13 Connect the power cable to the power connector on the drive.
14 Replace the center fan bracket. See "Replacing the Center Fan Bracket" on page 82.
15 Replace the fans into the center fan bracket. See "Removing and Installing a Fan" on page 53.
16 If applicable, reconnect the cables to the SAS RAID controller daughter card or SCSI controller card.
See "Installing the SAS RAID Controller Daughter Card" on page 98.
17 Route the SCSI interface cable through the cable guide in the center fan bracket and through the
expansion card edge guide.
18 Connect the SCSI interface cable to the SCSI connector on the optional SCSI controller card.
