Introduction 3
Introduction 0
The Quantum Scalar 50 automated tape libraries are controlled by a host
computer via a SCSI LVD bus using the SCSI-3 medium changer command
set.
The Quantum Scalar 50 allows for easy conversion from the SCSI host
interface to an iSCSI host interface. This document describes upgrading a
standard Scalar 50 library equipped with a SCSI host interface to an iSCSI
host interface using a TC2201 Upgrade kit.
TC2201 Bridge
Operation 0
Once a TC2201 bridge option is installed and tested, the library operates
exactly as a Scalar 50 with a SCSI host interface. Operation of the library via
the operator control panel (OCP) is unchanged.
Preparing for the TC2201 Installation 0
Before beginning the installation procedure, make sure that you have the
required upgrade kit and tools.
Required Upgrade Kits 0The TC2201 installation requires the following upgrade kit for every two tape
drives in a Scalar 50 library (see table 1):

4 TC2201 Upgrade Procedure
Required Tools 0The following tools are required to install the TC2201 bridge upgrade:
• #2 PHILLIPS® screwdriver
TC2201 Upgrade Procedure 0
The upgrade procedure is identical regardless of the number of TC2201s
installed except where noted. The upgrade procedure consists of the
following major steps:
•Preparing the Quantum Scalar 50 Library
•Removing Tape Drive SCSI Cables
•Installing the TC2201 Bridge
•Installing the Ethernet Cables
•Installing SCSI Cables
•Configuring the TC2201 Bridge Software
Preparing the
Quantum Scalar 50
Library 0
To prepare the Scalar 50 library:
1With the library turned on, press the Ops button on the OCP to access the
Operations screen (see figure 1).
Figure 1 Operations
Screen
2Select Library operations and press Enter.
3From the library operations menu, select Library on/offline and press Enter
to turn the library offline.
4Verify that the OCP display indicates “Offline” from the OCP screen.
Caution: Use appropriate ESD procedures when assembling and
installing the TC2201 option.

TC2201 Upgrade Procedure 5
5Turn off the power by pressing the power button located on the front of
the library (see figure 2).

Library
Removing Tape Drive
SCSI Cables 0
Each pair of tape drives within the library are connected via a SCSI cable.
These cables must be removed prior to cabling the TC2201.
1Locate the SCSI cables connecting each pair of tape drives in the library
and the host systems (see figure 3). Tape drive 1 is in the upper right-
hand drive bay, tape drive 2 is in the upper left-hand drive bay, and so
forth.
Figure 3 Scalar 50 Cabling
Configuration
2Remove all SCSI cables connecting each tape drive and also all
terminators.
Note: Save the SCSI cables connected to the SCB for later use.

6 TC2201 Upgrade Procedure
Installing the TC2201
Bridge 0
To install the TC2201 bridge:
1Loosen the two PHILLIPS screws securing the blank off plate to the CPCI
card cage and expose the slot needed for the TC2201 installation.
2With the SCSI ports located to your right as you face the back of the
library, slide the first TC2201 into the slot of the card cage (see figure 4).
Figure 4 Installing a
TC2201 Bridge
3Gently press down on the TC2201 until the board is seated in the card
cage and the ejector latches lock in place (see figure 5).

8 TC2201 Upgrade Procedure
Installing the Ethernet
Cables 0
Scalar 50 libraries with an installed TC2201 iSCSI bridge must have the
following Ethernet connection:
1Connect a cross-over cable between the right port of the library system
controller board (SCB) and the TC2201 (see figure 7).
Figure 7 Scalar Ethernet
Connection
Installing SCSI Cables 0The SCSI cable installation procedure differs depending on the type of tape
drive installed. Refer to the following sections for installing the SCSI cables:
•Installing SCSI Cables with Full Height Tape Drives
•Installing SCSI Cables with Half-Height Tape Drives
Installing SCSI Cables with Full Height Tape Drives 0
Use the following procedure to connect the SCSI cables and terminators to the
tape drives and TC2201.
• SCSI connectors 0 through 1 on the TC2201 are used to connect to the
system controller board and tape drives 1 through 2.
To cable a TC2201 bridge to the tape drive(s):
1To connect the SCSI cables from the TC2201 to the tape drives (see
figure 10 and figure 9):
aConnect a SCSI cable (VHDC 68-pin to HD 68-pin) from the top port
of the system controller board to Port 0 on the TC2201.
bConnect a SCSI cable (VHDC 68-pin to HD 68-pin) from the bottom
port of the system controller board to the upper port of tape drive 1.
cInstall a terminator on the bottom port of tape drive 1.

port of the system controller board to the upper port of tape drive 1.
cConnect a SCSI cable (HD 68-pin to HD 68-pin) from the bottom port
of tape drive 1 to the top port of tape drive 2.
dInstall a terminator on the bottom port of tape drive 2.
eConnect a SCSI cable (VHDC 68-pin to HD 68-pin) from the top port
of tape drive 3 to Port 1 on the TC2201.
fConnect a SCSI cable (HD 68-pin to HD 68-pin) from the bottom port
of tape drive 3 to the top port of tape drive 4.
