grounding straps, anti-static mats, and anti-static work stations when removing and replacing the
major assemblies.
Tools Required
The following tools are needed:
• Torx driver with the following bits: T-10, T-15, T-20
A T-20W bit may be helpful, but is not necessary.

Note
The “x” in the part numbers listed in the following parts tables
represents a number from “0” to “9” depending on the
revision of the part. For example, if the part is newly
released, the number will be “0”. The first time the part is
revised, the number increments to “1”; the second time the
part is revised, the number increments to“2”, and so on.
If you are unsure of the current part number, enter a “0” or a
“1” in place of the “x” when checking your parts database and
the current part number will be displayed.

Before You Begin
1. Look in the jukebox front "window" and make sure that there are no disks in any drive.
Use the control panel to eject any disk still in a drive
2. Bring the jukebox “down.”
Procedures for bringing this jukebox offline depend on the specific host system. Coordinate with
the system administrator to prepare this jukebox for the upgrade. This may involve “downing” the
host system also.
3. Remove power from the jukebox.
4. Disconnect the SCSI interface from the host.
Caution
Do NOT switch off power to the jukebox until you are sure the
SCSI bus is inactive. Switching off the jukebox when the
SCSI bus is active can cause data loss and/or indeterminate
bus states.
When doing this upgrade, be sure that disk cartridges are not
moved from their original slot locations. If you need to remove
the cartridges, record their SLOT LOCATIONS and
ORIENTATION so they can be replaced to their ORIGINAL
positions. Failure to follow this practice results in a serious
loss of file system integrity.

c. Insert the single drive into the enclosure and position it near the cables at the rear, and in the
upper portion of the enclosure — do not mount the drive at this point — the drive interface
cable and clip must be mounted in the next step.

Put the clip near the drive end of the cable. (Mounting the clip is shown separate from the drive
enclosure for clarity in Figure 6.)
Place the cable/drive connectors near each other. Remove the covering on the adhesive on the
back of the clip and press the clip into the position shown in Figure 7. Connect the drive inter-
