Congratulations on selecting the ADICScalar AIT 220 Library.
Your new library provides unattended data storage, archiving,
backup, and retrieval for mid-range and high-end workstations,
servers, and networks. The robotic cartridge handling mechanism
(CHM) automatically moves cartridges between tape drives and
storage slots, while the tape drives read and write data.
The library is available in standalone (vertical) and rack-mount
(horizontal) models, as shown in the figure.

The Scalar AIT 220 includes two data cartridge magazines and
either one or two 3.5”form factor SonyAITtape drives. It can
operate as three SCSI devices on up to three SCSI buses. When the
library is is equipped with AIT-1 drives, the library is a differential
SCSI-2 device and the drives are differential Fast/Wide SCSI-2
devices. When equipped with AIT-2 drives, the library can be
configured as a high voltage differential (HVD) Wide Ultra SCSI
device, or as a low voltage differential (LVD) Wide Ultra SCSI
device.
When operating with two AIT-2 tape drives and assuming an
average data compression ratio of 2:1, the Scalar AIT 220 can store
up to 2.0 terabytes of information on 20 Advanced-Metal
Evaporative (AME) data cartridges (SDX2-50C).
Employing the 3.5”form factor AIT-2 drive, the Scalar AIT 220
provides a maximum sustained data transfer rate of over 720 MB
per minute (assuming 2:1 data compression). The Wide Ultra SCSI
drive does not require periodic head cleaning as often as many
conventioanl tape drives. The drive constantly moinitors head
output to check for possible contamination. If present, the drive
will invoke a built-in Active Head Cleaner. Under extreme
operating conditions, a cleaning cartridge may be required and the
drive indicates this by displaying a Cleaning Request message on
its front panel Status LED.

,QVWDOODWLRQDQG2SHUDWLRQ L[
The Sony SDX1-25C, SDX1-35C, SDX2-36C, and SDX2-50C
data cartridges support the Advanced Intelligent Tape format. The
cartridges use a new recording format, Adaptive Lossless Data
Compression (ALDC), Memory In Cassette (MIC) technology
capabilities and use Sony’s AME media, which incorporates dual
cobalt magnetic layers, the absence of binder material to prevent
tape head contamination and a super-durable “diamond-like
carbon”protective coating for extreme durability.

SDoor and key lock. The front door features a key lock that
enables you to lock the door for data security.
SLCD and keypad (operator panel). The LCD (liquid crystal
display) and keypad allow you to view the operational status
of the library, access a menu of operations, and view status
messages. If necessary, you can tilt the LCD for easier viewing.

STape drives. The library can include one or two AIT-1 or
AIT-2 tape drives, which are housed in drive carriers.
SData cartridge magazine(s) and fixed slot. The Scalar AIT
220 includes two removable 10-tape magazines on a rotor. The
fixed slot allows you to store an AIT cleaning cartridge or an
additional AIT data cartridge.
SCHM (cartridge handling mechanism). The CHM is the
robotic assembly that moves cartridges between the storage
locations and the tape drives. The CHM also includes a bar
code scanner, which reads bar code labels affixed to the
cartridges.

SFan and power entry module. The fan reduces the library's
operating temperature. The power entry module includes the
AC power connector, power switch, and fuse drawer.
SRemote hardware reset port. This port allows you to connect
a remote reset cable for remote resets.
S9-pin and 25-pin serial ports. Two serial ports allow you to
connect a serial cable and terminal for diagnostics.
SSCSI connectors. The six SCSI connectors (four shown in
illustration) allow you to connect the library to the SCSI bus.

This chapter describes how to install and set up your library.
Preparing for installation
This section provides step-by-step instructions for preparing the library.
You can use the table below as a checklist.
Step 1 – Unpack the library
Complete the unpacking steps printed on the box. Save all the original
packing materials in case you need to ship or move the library later.
✔Step Description
1 Unpack the library.
2 Obtain accessories and equipment.
3 Prepare the host computer.
4 Prepare the library for installation.

&KDSWHU
6FDODU$,7
Step 2 –Obtain accessories and equipment
Make certain you have all the accessories and equipment for library
operation, as indicated in the table below. Many of these items are
included in the library accessories box, shipped in a separate box at the
top of the carton.
Required accessories and equipment
Power cord Included with the library. (Page 135
provides power cord specifications for
other voltages and international use.)
Two keys for front door Included with the library.
Jumper(s) for connecting the
library and tape drives to a single
SCSI bus.
Included with the library if two tape
drives are installed.
Eight 10-32 ×0.5 truss head
screws and clip nuts
Included with rack-mount libraries.
Two slide rails, attached to the
sides of the library
SCSI cables If these items are not included with the
library, contact ADIC to purchase them.
If you want to use your own, see
Appendix A for specifications.
SCSI bus terminator(s) (required
if the library or one of the tape
drives is the last device on the
bus)
AIT data cartridges and cleaning
cartridges
If cartridges are not included with the
library, contact ADIC to purchase them.
If you want to use your own, refer to
page 49 for appropriate data cartridges
and to page 59 for appropriate cleaning
cartridges.

,QVWDOODWLRQDQG6HWXS
,QVWDOODWLRQDQG2SHUDWLRQ 
Step 3 –Prepare the host computer
Make certain the SCSI host bus adapter card installed in the computer
and the application software are compatible with the Scalar AIT 220.
You can obtain software compatibility information about ADIC
products from ADIC’s internet site (http://www.adic.com).
Note: If your application only supports a single AIT tape drive, you
can run the library in one of the sequential modes (see page 46
and page 153).
You can install the software application on the host computer before or
after library installation. However, if you install the software first, you
may need to reconfigure it for use with the library.
Step 4 –Prepare the library for installation
Prepare the library as follows:
SEnsure that the work area is free from conditions that could cause
electrostatic discharge (ESD). Discharge static electricity from your
body by touching a known grounded surface, such as your
computer's metal chassis.
SLocate an appropriate area for the library. The library must have a
level surface near a readily accessible outlet. (If you have a
standalone library, adjust the feet to make it level.) In addition, there
must be approximately six inches (15 cm) of open area behind the
library for adequate air flow.

Installing the library hardware
This section provides step-by-step instructions for installing the library
hardware. You can use the table below as a checklist.
✔Step Description
1 Install the library into a rack, if you have a rack-mount model.
2 Unlock and open the front door.
3 Remove the packing foam.
4 Prepare and install cartridges.
5 Close and lock the door.
6 Connect the library to the SCSI bus.
