Tk70 Tape Drive Controls - DEC VAX 4000 300 Manual

You should use a CompacTape II as an output device to make copies or
backups of software or data. The TK70 drive cannot write to a CompacTape
II or CompacTape that has been previously written by a TK50 tape drive.

TK70 Tape Drive Controls

The tape drive has two primary controls: the cartridge insert/release handle
(subsequently referred to as the ''handle'') and the Unload button. You use
the handle to insert or remove cartridges and lock them into position. Pull
the handle open to insert or remove a tape cartridge. Push the handle
closed to lock a tape cartridge into position and load the tape.
You use the Unload button to rewind and unload the tape. Rewinding and
unloading can also be controlled by software. Refer to your system software
manuals for appropriate commands.
The drive also has three indicator lights that show the status of the drive.
• Orange light (Write-Protected):
cartridge is write protected.
• Yellow light (Tape in Use): A steady yellow light shows the tape is
loaded. A blinking yellow light shows the tape is in motion.
• Green light (Operate Handle): A steady green light shows you can move
the handle to insert or remove a tape. A blinking green light shows a
cartridge load fault. You can also move the handle when the green light
is blinking.
All three lights blinking simultaneously indicate a fault condition.
Figure 3–8 shows the TK70 tape drive with the controls and indicator lights
labeled.
To operate the drive properly, you must carefully monitor the indicator
lights. The instructions for inserting and removing cartridges, which
appear later in this section, tell you what should happen at each step. A
table at the end of the section summarizes light and control combinations.
