PRODUCT OVERVIEW
The Exabyte 221L and 221L-FC LTO Ultrium tape libraries provide unattended
data storage, archiving, backup, and retrieval for midrange and high-end
workstations, servers, and networks.
The 221L library has a SCSI interface; the 221L-FC library has a Fibre Channel
interface. Both libraries are available with LTO Ultrium 1, Ultrium 2, or
Ultrium 3 Fibre Channel tape drives and feature Exabyte’s patented,
award-winning ExaBiotics™.
LIBRARY FEATURES
The Exabyte 221L and 221L-FC libraries include the following features:
Storage for up to 21 data cartridges. Cartridges are stored in two removable
cartridge magazines containing seven slots each and seven additional fixed
cartridge slots mounted next to the tape drive(s). The removable magazines
are easily accessible from the front panel and can be used with an
interlocking lid to store cartridges outside of the library.
One or two LTO Ultrium tape drives. The tape drives are installed in drive
carriers that allow easy installation and removal from the library.

2PRODUCT MANUAL 1014258
CHAPTER 1—PRODUCT OVERVIEW
Entry/exit port. The entry/exit port allows you to insert and remove
cartridges without opening the library’s door and interrupting operation.
Robotic cartridge handler (robot). The robot moves cartridges between the
storage slots, tape drive(s), and the entry/exit port.
Bar code scanner. The library uses a laser bar code scanner, attached to the
robot, to read bar code labels on the data cartridges. The library stores the
bar code information as part of its cartridge inventory.
Operator panel with LCD display. The operator panel allows you to
monitor library operations, select configuration options, and control the
robot from the front panel.
Wide, low-voltage differential (LVD) SCSI interface (221L). The 221L
library and SCSI LTO Ultrium tape drive(s) each support independent sets
of SCSI messages and commands and can be connected to separate LVD
SCSI buses.
Native Fibre Channel interface (221L-FC). The 221L-FC’s native Fibre
Channel interface allows seamless integration into data-intensive storage
area network (SAN) environments.
Standalone or rack-mount capability. The library is designed to operate as
a standalone unit or in a standard 19-inch rack. Rack-mounting kits are
available from Exabyte.
Ethernet port for connection to a 10/100BaseT Ethernet network. You can
connect the library to an Ethernet network for remote monitoring,
management, upgrading firmware, and creating diagnostic listings.
Built-in remote management capability. You can use the library’s built-in
Remote Management utility and a standard web browser to set
configuration options, view library information, monitor, and manage
operation over an Ethernet network.
Note: Your library may include Exabyte Library Monitor software on CD.
Exabyte Library Monitor is an older program for remote monitoring
that has been replaced by the library’s built-in Remote Management
utility. The Remote Management utility is available with the latest
library firmware. You can download the latest firmware from
Exabyte’s web site (www.exabyte.com). Instructions for upgrading
library firmware are provided on page 143.

LIBRARY COMPONENTS
LIBRARY COMPONENTS
The following sections describe the library’s front panel, internal, and back
panel components.
FRONT PANEL COMPONENTS
Figure 1-1 shows the library’s front panel components.
Operator Panel (LCD and Keypad) The operator panel includes a keypad
and a two-line, 32-character liquid crystal display (LCD). You can use the
operator panel to perform the following activities:
View library and tape drive status and information
Set or change library configuration options
Unlock the door
Lock and unlock the entry/exit port
Run demonstration programs and test library operations
Reset the library and tape drive(s)
Entry/Exit Port The entry/exit port door on the front of the library provides
access to the entry/exit port caddy (see Figure 1-2). This caddy allows you to
insert or remove a single cartridge without opening the library door.
To help maintain cartridge security and to provide safety from possible laser
beam exposure, a solenoid-activated lock secures the caddy in the entry/exit
port.

CHAPTER 1—PRODUCT OVERVIEW
Door The door allows manual access to the library’s internal components,
including the tape drive(s), cartridge magazines, and fixed cartridge slots.
To help maintain cartridge security and to provide safety from possible laser
beam exposure, the door is secured by a solenoid-activated electronic locking
system. The library will not operate when the door is unlocked.
INTERNAL COMPONENTS
Figure 1-2 shows the internal components of the 221L. Except for the Fibre
Channel interface on the tape drive, the components described in this section
are identical for the 221L-FC.
