The SCD Dot is only illuminated if the LTO tape drive is both in Maintenance mode AND
there is a drive dump available.
Status Lights During Power-on or Reset
During power-on, or a drive reset, the drive front panel displays drive progress as follows:
1. SCD displays random segments (no lights ON).
2. SCD displays random segments (Ready light ON).
3. SCD displays random segments (Fault light ON).
4. SCD displays
8
(Ready, Fault, Encryption, and SCD dot lights are all ON).
5. SCD goes blank (with Ready light ON) after a successful power-on or reset.
If an error is detected during the power-on or reset, the tape drive posts an error code to the
SCD. To determine the error, locate the code in the
“Error Codes Table” on page 62 .
