Message Display The message display ( 3 in Figure 5 on page 15) is a liquid crystal display (LCD) that provides information about the status of the 3580 Tape Drive and any error conditions. The message display consists of two rows, with 20 characters available in each row. During operation, the message display processor continuously queries the drive and updates the display with status messages. When in an idle (nonoperating) state, the tape drive displays the following message: Ultrium Tape Drive Drive Empty If the message display processor loses communication with the 3580 Tape Drive, the unit displays the following message (where xxxx equals the message that was present when the processor lost contact): xxxx ... Note: The preceding message may occasionally display during normal processing. Single-Character Display The 3580 Tape Drive features a light-emitting diode (LED) ( 4 in Figure 5 on page 15) that presents a single-character code for: v Error conditions and informational messages v Diagnostic or maintenance functions (while in maintenance mode only) Table 6 on page 39 lists the codes for error conditions and informational messages. If multiple errors occur, the code with the highest priority (represented by the lowest number) displays first. When the error is corrected, the code with the next highest priority displays, and so on until no errors remain. Table 7 on page 41 lists the single-character codes that represent diagnostic or maintenance functions. To initiate a function you must be in maintenance mode. For more information, see "Appendix B. Performing Diagnostic and Maintenance Functions" on page 41. The single-character display is blank during normal operation of the 3580 Tape Drive. 18 IBM 3580 Tape Drive Setup, Operator, and Service Guide

Message Display
The message display (
±3²
in Figure 5 on page 15) is a liquid crystal display (LCD)
that provides information about the status of the 3580 Tape Drive and any error
conditions. The message display consists of two rows, with 20 characters available
in each row. During operation, the message display processor continuously queries
the drive and updates the display with status messages. When in an idle
(nonoperating) state, the tape drive displays the following message:
Ultrium Tape Drive
Drive Empty
If the message display processor loses communication with the 3580 Tape Drive,
the unit displays the following message (where
xxxx
equals the message that was
present when the processor lost contact):
xxxx
...
Note:
The preceding message may occasionally display during normal processing.
Single-Character Display
The 3580 Tape Drive features a light-emitting diode (LED) (
±4²
in Figure 5 on
page 15) that presents a single-character code for:
v
Error conditions and informational messages
v
Diagnostic or maintenance functions (while in maintenance mode only)
Table 6 on page 39 lists the codes for error conditions and informational messages.
If multiple errors occur, the code with the highest priority (represented by the lowest
number) displays first. When the error is corrected, the code with the next highest
priority displays, and so on until no errors remain.
Table 7 on page 41 lists the single-character codes that represent diagnostic or
maintenance functions. To initiate a function you must be in maintenance mode. For
more information, see “Appendix B. Performing Diagnostic and Maintenance
Functions” on page 41.
The single-character display is blank during normal operation of the 3580 Tape
Drive.
