Adding 2 Drives to the C1107 Series Jukebox
ESD Precautions
The optical disk jukebox contains very sensitive electrical components. It is EXTREMELY IMPOR-
TANT that you follow the proper procedures for preventing ESD (Electrostatic Discharge). Use wrist-
grounding straps, anti-static mats, and anti-static work stations when removing and replacing the
major assemblies.
a. If you want to add more than one drive upgrade to the C1104F/G/H, you must first install a capacity
upgrade( C1159F/G/H). Installing a capacity upgrade gives the product a C1107F/G/H configuration.

Note
This document is not necessarily revised as each part number
is revised.
In the above list, an “x” is placed in “service” part numbers
(parts orderable from Support Materials Organization) to
designate that this digit increments when the part is revised.
This digit usually starts at “0” and increments up to “9.”
Knowing this should help you locate the correct part at SMO.
For any other parts that may be missing from this kit, contact
your supplier.

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.

Installing the 2-Drive Upgrade
Note
There are 2 drives installed in each drive enclosure.
If you are upgrading a 1/2-capacity configuration jukebox
that has 4 drives, you will currently be using the top 2 drive
enclosures, and will add 2 drives to the drive enclosure that is
3rd from the top.
If you are upgrading a 1/2-capacity configuration jukebox
with 6 drives, you must add the capacity upgrade (C1159F/G/
H, which includes 3 empty drive enclosures) at the same time
that you add the drive upgrade.
If you are adding two drives to a full configuration with 6, or
10 drives, install the drives in the first available empty drive
enclosure from the top. DO NOT skip drive mounting
locations. See the right-hand box in Figure 1.
If you are upgrading to a 10-drive unit, move the drives at
position #3 down to position #5, move the fan at position #5
up to position #3, and add the new drives in position #6.
Enclosure #3 must not contain drives. Positioning the drives
in this way in a 10-drive upgrade matches the way 10-drive
jukeboxes ship from the factory after February, 1998. This
configuration enables future connection into a high-
availability environment if requested by the customer. See the
left-hand box in Figure 1.

1. Remove the 3 right-side panels.
The side panels have 2 T-20 screws on the bottom edge. Start from the bottom panel first.
Figure 2: Screws on side and rear panels
2. Remove the two RFI panels .
There are 6 T-20 screws around the edge of each panel.

3. If upgrading to an 8- or 12-drive configuration, remove the first available (empty) drive enclosure
from the top. If upgrading to a 10-drive configuration, remove the drive enclosure at position #6
(see Figure 1).
a. Disconnect the fan power cable from the interposer PCA.
b. Remove the 2 T-20 screws from each side of the drive enclosure and remove the drive enclo-
sure.
4. Remove the top cable access panel on the top rear of the drive enclosure.
The access panel will rotate out if the 2 T-10 mounting screws on either side of the enclosure are
removed.
5. Place the (empty) drive enclosure on its side and trim off the top half of the cable hole edge protec-
tor. Use a utility knife to cut through the middle of each side of the edge protector. Remove the top
half. See Figure 4.
Cutting off this portion of the edge protector allows the L-shaped air seal that will be mounted later
to stick,

6. Check the DIP switches on the top of the drives. Make sure they are set to OFF, which is in the
forward position (toward the front of the drive.) Refer to Figure 5 for DIP switch location and
orientation on the top of the drives.

7. Install drives in the drive enclosure.
a. Mount the drive interface cable clips on the cable as shown in Figure 6.
