Always let a cartridge acclimate to the operating environment before you use it.
Acclimation is necessary for any data cartridge that has been exposed to a different
humidity environment or to a temperature change of 11°C (20°F) or more. Place the
cartridge, with its container, in the operating environment for as long as it has been
away from the operating environment or for 24 hours, whichever is less.
Operating the 12/24GB 4mm Tape Drive in Harsh Environments
The tape drive is ideally suited to streaming operations rather than tape movement
operations involving multiple stops and starts and random searches. You should use
streaming movement whenever possible.
Do not use for archiving any tape that was previously used outside the ranges specified
in “Environmental Considerations for 12/24 GB 4 mm Data Cartridges” on page 32 for
an extended period of time. Exposure to the new environment deteriorates the magnetic
and physical strength of the tape. Do not store important data on a tape that was used
outside the specified ranges. For reliable archiving, transfer the data to a new tape.
Status Lights
The 12/24GB 4mm Tape Drive has two green status lights and one amber status light.
The on and off combinations of the status lights indicate the conditions of the 12/24GB
4mm Tape Drive.
Each of the International Organization for Standards (ISO) symbols located above a
status light indicates a specific condition of the tape drive as follows:
1 Tape Drive Door
2 Status lights
3 Ready (green)
4 Tape Motion (green)
5 Disturbance (amber)
