Drive Carriers and Service Access Covers The library contains one or two
LTO Ultrium tape drives installed in Exabyte drive carriers. In the 221L, each
drive carrier includes two SCSI connectors for connecting the tape drive to a
SCSI bus. In the 221L-FC, each drive carrier includes one integrated dual LC
optical fiber connector for connecting the tape drive to a single loop on a Fibre
Channel network.
The drive carrier allows the tape drive to be easily inserted and removed from
the library. The drive carrier includes a fan to maintain the operating
temperature of the tape drive. If your library contains only one tape drive, the
unused drive slot is protected by a drive bay service access cover.
Library SCSI Connectors (221L) The 221L library has two 68-pin, wide LVD
SCSI connectors for connection to a SCSI bus. The connectors accommodate
either two SCSI cables or a cable and an external terminator. The library can be
on the same bus as the tape drive(s) or on a separate bus.
Library Fibre Channel Connector (221L-FC) The 221L-FC library has one
integrated dual LC optical fiber connector for connection to a Fibre Channel
network. The library can be on the same loop as the tape drive(s) or on a
separate loop.
Ethernet Port The Ethernet port allows you to connect the library to a
10/100BaseT Ethernet network. You can use the Ethernet connection to
perform the following activities:
Monitor and manage library operation remotely
Download diagnostic information from the library
Upgrade the library’s firmware
9-Pin Serial Port A 9-pin serial port allows the library to be connected
directly to a computer for diagnostics and firmware upgrades.
Power Entry Module The library chassis is grounded through the power
entry module. The module includes the power cord connection and the power
switch. The power cord connection provides AC power to the internal power
supply for the library and the tape drive(s). The power switch allows you to
turn power on and off for the library and the enclosed tape drive(s).
Fans The system fan provides cooling for the library. Each drive carrier also
includes a fan to provide optimal cooling for the enclosed tape drive.
