Using the Power-On
Self-Test
The SDLT 600 tape drive performs a self-diagnostic test,
called a Power-On Self-Test (POST), each time you power it
on. This test helps you detect problems with your tape drive.
POST completes in approximately 10 seconds. While POST
is in progress, the tape drive responds BUSY to SCSI
commands.
If the host computer attempts to negotiate synchronous or
wide transfers, the tape drive negotiates to asynchronous or
narrow. It may take longer than the duration of POST for the
tape drive to become ready.
During POST, each LED lights in sequence.When POST is
complete, the green Drive Status LED lights steadily.
If the tape drive fails POST, check for the following possible
problems:
There is no cartridge in the tape drive.
The tape drive is not receiving adequate power (try a new
cord or different outlet).
The tape drive is not properly connected to the host
computer and other SCSI devices.
If any of these problems exist, correct the problem, power
off the tape drive and power it back on to restart POST. If
none of these problems exists or the tape drive fails POST
after you have corrected them, refer to additional
troubleshooting information in the SDLT 600 Product
Manual available on the product CD-ROM.
!
Do not attempt to open the tape drive enclosure. Only a
qualified technician should perform service.
