Introduction
About this Manual
This manual describes the procedure for replacing the transport tray assembly in a
Spectra 12K Library or a Spectra 64K library, and how to configure and calibrate the
assembly after it has been installed.
About the Transport Tray Assembly
The transport tray assembly in Spectra 12K and Spectra 64K libraries moves within the
robotic rack assembly. Its job is to transport tape cartridges between the tape drives,
tape slots, and the entry/exit (E/E) port(s). The main component of the transport tray
assembly is the robotic picker, which handles the tape cartridges. The robotic picker
has arms that grab and hold one tape cartridge at a time while it travels along the
transport tray. A bar code reader located on the robotic picker reads the bar code label
on each tape cartridge to ensure accuracy.
Estimated Time Required
This procedure should take about one and one-half hours.

Materials and Tools Required
You will need a transport tray assembly from Spectra Logic or an authorized reseller:
• Transport Tray Assembly, P.N. 90919005
You will also need the following tools:
• A #1 Phillips screwdriver

• A wire cutter
• Snap ring pliers
• The library door key
• The key to the rear door of the library (Spectra 64K libraries only)

Prepare the Library and Host System
Shut down the library while keeping the host interface connected to the host system.
1. Disable any backup software that might try to access the library.
Warning: Electric shock inside the library can cause injury or death.
Disconnect AC power before opening the library door.
2. Turn off the power. The power switch is located at the rear of the library on the
lower left. (It is necessary to unlock and open the rear door of Spectra 64K
libraries.)
3. If necessary, move the library to a location where you have full access to the front
of the library.
Caution: The library is heavy. Get help when moving the library.
• The Spectra 12K library weighs approximately 210 pounds
(95.25 kg).
• The Spectra 64K library weighs approximately 900 pounds
(408.23 kg).
4. Use the library key to unlock and open the front door of the library.
5. Remove the drives from the drive bay and set them aside in a safe place.
Note: It is not necessary to remove the media.
6. Proceed to Remove the Robotic Rack Assembly on page 7.

Remove the Robotic Rack Assembly
1. Lower the transport tray to bottom of the robotic rack by gently raising the counter
weight (Figure 2).
Figure 2 The robotic rack counter weight is raised (Spectra 64K
library shown).

2. Rotate the picker so that the bar code scanner faces the rear of the library.
The location of the barcode scanner is shown in Figure 3.
3. Slide the picker along the transport tray to the front of the library (Figure 4).

4. Look at the bottom of the library where the drives are located. If there is a hinge
connecting the left side of the drive slots to the back of the library (Figure 5), go to
Step 5.
If your library does not have a hinge (Figure 6), go to Step 6.
5. Using the appropriate screwdriver, loosen the screws just enough to move the gate
out of the way from the robotic rack assembly (Figure 7).
• Some Spectra 12K libraries have three screws in the gate, and some units will
have no screws in the gate.
• All Spectra 64K libraries have five screws in the gate.

6. Unplug the 25-wire black connector at the bottom front of the robotic rack
assembly (Figure 8 and Figure 9).
7. Using the #2 Phillips screwdriver, loosen the screws that hold the robotic rack
assembly to the chassis: first the top, then the bottom (Figure 10).
Note: Some Spectra 12K library models have only four screws attaching
the robotic rack to the chassis.
