Power Button
The Power button is a push button that turns the tape drive on or off.
The button is located on the front panel (see 7 in Figure
3 on page 13).
When the Pow
er button is in the off position, the primary electrical
power within the enclosure is still active. To remove all electrical power
to the enclosure, unplug the power cord from the receptacle at the rear
of the drive.
When the unit is powered-on but idle, the Ready light
(see 2 in Figure 3
on page 13) is solid green; when it is performing a function, the Ready
li
ght is flashing green.
Single-character Display (SCD)
The SCD (5 in Figure 3 on page 13) presents a single-character code for:
• Error conditions and informational messages
• Diagnostic or maintenance functions (while in maintenance mode
only)
Appendix
A, Error Codes and Messages lists the codes for error
conditions and informational messages. If multiple errors occur, the
code with the highest priority (represe
nted 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.
Diagnostic and Maintenance Functions on page 45 lists the single-
character codes that represent diagnostic or maintenance functions. To
initiat
e a function the unit must be in maintenance mode.
