IBM TS2900 Setup, Operator, And Service Manual page 242

encryption key manager (EKM). A Java software
program that assists IBM-encrypting tape drives in
generating, protecting, storing, and maintaining
encryption keys that encrypt information written to and
decrypt information read from tape media.
entitlement. IBM entitlement is the official right to
receive service and support for your tape library.
EPO. Emergency power off.
EPROM. Erasable programmable read only memory.
EQC. Equipment check.
equipment check. An asynchronous indication of a
malfunction.
Error log. A dataset or file in a product or system
where error information is stored for later access.
ESD. Electrostatic discharge.
ESP. Encapsulating Security Payload. This is an
Internet Protocol that provides origin authenticity,
integrity, and confidentiality protection of a packet. ESP
also supports encryption-only and authentication-only
configurations, but using encryption without
authentication is strongly discouraged because it is
insecure.
F
fault symptom code (FSC). A hexadecimal code
generated by the drive or the control unit microcode in
response to a detected subsystem error.
FC. Feature code.
FCC. Federal communications commission.
FE. Field engineer, customer engineer, or service
representative.
fiducial. A target used for teaching a physical location
to a robot.
field replaceable unit (FRU). An assembly that is
replaced in its entirety when any one of its components
fails.
file. A named set of records stored or processed as a
unit. Also referred to as a dataset.
file protection. The processes and procedures
established in an information system that are designed
to inhibit unauthorized access to, contamination of, or
deletion of a file.
I-4
TS2900 Tape Autoloader Setup, Operator, and Service Guide
file transfer protocol (FTP). In the Internet suite of
protocols, an application layer protocol that uses TCP
and Telnet services to transfer bulk-data files between
machines or hosts.
firmware. Proprietary code that is usually delivered as
microcode as part of an operating system. Firmware is
more efficient than software loaded from an alterable
medium and more adaptable to change than pure
hardware circuitry. An example of firmware is the Basic
Input/Output System (BIOS) in read-only memory
(ROM) on a PC motherboard.
FLASH EEPROM. An electrically erasable
programmable read-only memory (EEPROM) that can
be updated.
FMR. Field microcode replacement.
format. The arrangement or layout of data on a data
medium.
formatter. Part of a magnetic tape subsystem that
performs data conversion, speed matching, encoding,
first level error recovery, and interfaces to one or more
tape drives.
FP. File protect.
frayed. Damaged as if by an abrasive substance.
FRU. Field replaceable unit.
FSC. Fault symptom code.
FSI. Fault symptom index.
FTSS. Field Technical Sales Support.
functional microcode. Microcode that is resident in the
machine during normal customer operation.

g. Gram.
GB. gigabyte.
GBIC. Gigabit Interface Converter.
Gbs. gigabits/second
gigabit (Gbit). 1 000 000 000 bits.
gigabyte (GB). 1 000 000 000 bytes.
Gigabit Interface Converter (GBIC). Converts copper
interface to optic interface.
