WARNING!
The SL24 Tape Autoloader weighs up to 15.6 kg (34.3 lb) without media and up to 20.4 kg (44.9 lb)
with media (24 cartridges). The SL48 Tape Library weighs up to 24.6 kg (54.1 lb) without media
and up to 34.2 kg (75.2 lb) with media (48 cartridges).

Recording configuration settings
If the OCP or RMI works, write down the system, drive, and network configuration settings. You will
need these settings to re‐configure the Autoloader or Library after replacing the chassis.

Tip:
Recording the configuration settings is a good idea in case the library controller card has a problem or is
damaged during the transfer to the new chassis.

Removing the tape cartridge from the tape drive
Before beginning, be sure no cartridges are in the tape drives. To move a cartridge with the SL24 OCP,
see “Moving tapes in the Autoloader (Operations > Move Tape)” on page 105.  To move a cartridge
with the RMI, see “Moving media” on page 80.

CAUTION:
If you cannot remove the tape cartridge from the tape drive, handle the tape drive gently during the rest of the procedure to avoid damaging the tape and losing data.

Removing the cables, magazines, and tape drives
Power off the Autoloader or Library. Remove the power cord and other cables from the Autoloader or Library.
Remove the magazines from the device using the manual process (see “Releasing the magazines manually” on page 150).

To remove the tape drives:
1. Loosen the blue captive thumbscrews on the drive (see Figure 113).
2. Pull straight back on the tape drive handle to remove the tape drive from the Autoloader or
Library (see Figure 114).
3. Repeat Steps 1 and 2 for all other tape drives.

To remove the power supply:
1. Loosen the three captive thumbscrews on the power supply.
2. Grasp a thumbscrew stem on each side of the power supply. Support the bottom while pulling the power
    supply out of the Library, as shown in Figure 115.

To remove the library controller:
1. Loosen the two blue thumbscrews on the library controller and remove it from the Library, as shown in
    Figure 116.
2. Place the library controller into a static safe bag.

Removing the base chassis
You will need a #2 Phillips screwdriver to remove and replace the base chassis assembly from the rack or cover.

CAUTION:
Lift the Autoloader or Library from the side edges. Lifting the Autoloader or Library from the magazine or tape drive openings can damage the Autoloader or Library.

To remove the base chassis from the rack or table top conversion cover:
1. Obtain adequate assistance to lift and stabilize the Autoloader or Library during removal and  
    replacement.
2. From the front of the Autoloader or Library (see Figure 117, 1) loosen the screws inside the left and right
    front bezel (these are captive screws and cannot be removed), then 2) slide the Autoloader or Library
    out of the rack or cover using assistance.

Unpacking the new chassis
Unpack the new chassis and place it on a sturdy table. Save the packaging materials to return the
old chassis.

Replacing the base chassis

CAUTION:
Lift the chassis from the side edges. Lifting the chassis from the magazine openings can damage the chassis.

To replace the Autoloader or Library components and install the base chassis in the rack or in the
tabletop conversion cover:
1. The shipping lock prevents the robotic transport mechanism from moving during shipment. You must
    remove the shipping lock before powering on the device. The shipping lock is held in place with a piece
    of tape and is located in the top center of the new chassis. After the shipping lock is removed, it should
    be stored on the back panel of the chassis for future use.

To remove and store the shipping lock:
a. Locate the tape and lock at the top of the chassis (see Figure 118).
b. Remove the tape, then remove the lock.
c. Store the lock on the back panel of the device (see Figure 119).
2. Mount the Autoloader or Library in a rack or in the tabletop conversion cover.

To mount the Autoloader or Library in a rack:
a. With assistance, slide the Autoloader or Library onto the metal rails that are already in position in the
    rack.
b. From the front of the device, secure the front bezel to the rack using a #2 Phillips screw driver placed
    through the small holes in the mounting bracket to tighten the captive screws on each side of the device.

To replace the tabletop conversion cover:
a. Set the new base chassis on a sturdy surface in front of the cover.
b. Slide the chassis into the cover until the front panel of the chassis is aligned with the cover.
c. Tighten the captive screws on the chassis front panel until the cover is secure.

3. Replace the tape drives.
4. Replace the magazines.
5. Replace the cords and cables.
6. Reconnect the cables and power cord.
7. Power on the Autoloader or Library.
8. Reconfigure the Autoloader or Library.

Repackage the old chassis and return to Logistics for credit.
