Front Panel LED Operation

Page 34
The front panel of the Scorpion 24 drive contains two rectangular LEDs. The yellow
rectangular LED indicates the drive status, and the green rectangular LED indicates
the cartridge status. These two indicators provide operating information for normal
conditions and error conditions.
The drive status LED indicates the following conditions:
z
When ON (lit), the drive is reading or writing the tape. (SCSI or drive activity is
present.)
z
When flashing rapidly, a hardware fault has occurred. If this situation occurs
immediately after power-on and you have enabled the power-on self-test
through a jumper setting, the power-on self-test may have failed. In that case,
the drive will not operate.
Note. During a SCSI Prevent Media Removal command, the LED is always ON.
Note. Do not push the eject button while the yellow drive status LED is ON. If you
do, the operation in progress is aborted and the cartridge ejected, possibly
causing a loss of data.
The cartridge status LED indicates the following conditions:
z
When ON (lit), a cartridge is inserted and the drive is operating normally.
z
When flashing slowly, a cartridge is inserted but is generating excessive media
errors beyond a predefined error threshold. This signal is a warning only and
does not indicate a loss of data.
Whenever the cartridge status LED flashes slowly to warn of excessive media
errors, the operator should clean the drive heads using an approved cleaning
cartridge (such as the Seagate Model M7301).
If the LED continues to flash or flashes while ejecting a cartridge, use a new
cartridge for future writes as a precaution.
Note. As routine maintenance, the drive heads should be cleaned after every 25
hours of operation. Even though the Scorpion 24 drive has an internal
cleaning mechanism, a regular cleaning routine helps reduce errors due to
environmental contaminants such as dust, carpet fibers or airborne debris.
z
When flashing rapidly, the drive could not write the tape correctly (maximum
rewrite count exceeded). The WRITE operation failed.
First, clean the drive heads using an approved cleaning cartridge, such as the
Seagate Model M7301. If the LED continues flashing, use a new cartridge for
future writes.
