Introduction
About this Manual
This manual describes the procedure for replacing the transport tray assembly in a
Spectra 20K 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 20K 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. 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.

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.
3. If necessary, move the library to a location where you have full access to the front
of the library.
Caution: The library weighs approximately 240 pounds (108.86 kg). Get
help when moving the library.
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.

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.

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. Unplug the 25-wire black connector at the bottom front of the robotic rack
assembly (Figure 5).
5. Using the flat head screwdriver, remove the three cone head screws that hold the
robotic rack to the drive slot assembly (Figure 6).

6. Using the #2 Phillips screwdriver, remove the screws that hold the robotic rack
assembly to the chassis: first the top, then the bottom (Figure 7).
7. From the front of the library, carefully slide the robotic rack assembly outward
about six inches (15.24 cm) (Figure 8).
