Operator Panels

1-14 Sixth Edition 95741

Display

The operator panel has an alphanumeric display that indicates:

• Drive status

• Menu selections and configuration choices

• Error messages and fault symptom codes

• Host-generated messages

• Tape bar, if activated

The display is formed by a horizontal array of 10 segments. Each segment is

formed by an array of 35 dots—five wide and seven high. When the tape bar is

not activated, the lighted segments and dots form text messages. The text

messages may display steadily, flashing, or alternating with other messages.

Tape Bar

The tape bar uses the operator panel display to show the amount of tape that

has been written and read (Figure 1-14 on page 1-15). The tape bar is a

configuration option that must be activated by authorized service personnel.

Once activated, it appears on the operator panel display when the drive is

reading or writing.

When the tape bar is activated, the segments and dots simultaneously show the

percentage of the total tape length that has been written and read. Each dot

represents 2% of the tape length; each segment represents 10%.

Note: The tape bar gets its information from the media information region

(MIR) on the tape. The MIR is written to the tape when the tape is

unloaded. If the MIR is bad, the tape bar does not display. To rewrite the

MIR, see (TBD).

Write Bar

As data is written to tape, the lighted dots forming the write bar appear at the

left side of the display and advance to the right. The write bar uses the full

height of the display. As the dots fill the display, note that only every other dot

is lighted. The point where the write bar ends is the percentage of tape written.

Read Bar

As data is read from the tape, the read bar appears in the center of the write bar

as a single row of unlighted dots. This row is bordered above and below by

single rows of lighted dots. The read bar also begins at the left side of the

display and advances to the right. The point where the read bar ends is the

percentage of tape that has been read.
