26 Operating the Autoloader Chapter 2
LED Indicators
The Operator's Panel includes four LED indicators that provide a variety of
information as detailed in the following table:
Table 2 LEDs
LED Color Description
Ready/Activity Green Illuminated when power is on. Blinking whenever there is
tape drive or autoloader robotics activity.
Clean Drive Amber Illuminated when the tape drive needs to be cleaned.
Indicates that 250 tape motion hours have passed since
the last cleaning. The LED turns off when cleaning is
successfully completed. See Cleaning the Tape Drive on
page 36.
Media Attention Amber Illuminated if a media-related error has occurred. The
offending cartridge will also show a “!” in the cartridge
inventory display for the corresponding slot.
This condition can be the result of:
■ faulty or improperly degaussed media
■ media that has been previously written in an invalid
format such as DLT 7000 or DLT 8000
■ dirty read/write heads in the tape drive
■ an invalid cartridge (DLTtape III or non-DLT1) being
inserted
If these symptoms occur on multiple known good
cartridges, consider cleaning the tape drive. See Cleaning
the Tape Drive on page 36. If a particular cartridge
causes these symptoms repeatedly, that cartridge may be
defective or invalid, and should be discarded.
Error Red Illuminated if an unrecoverable tape drive or autoloader
error occurs. A corresponding error message appears on
the LCD screen. For more information, see Diagnostics and
Troubleshooting on page 51.
