Rewinding Tape; Unloading Tape; Restarting The Tape Drive - Digital Equipment MicroVAX 3600 Operation

3.1.3.4 Rewinding Tape
During normal operation, you do not need to rewind the tape, as tape
movement is under program control. However, under unusual circumstances,
such as a host system failure or a loss of communications with the host, you
may wish to rewind the tape under local control. Rewind the tape as follows:
1. If the tape drive is on-line (ON LINE indicator is lit), press the ON LINE
switch once to place the drive off-line.
2. Press the REWIND switch. The LOAD/REWIND indicator blinks while
the tape is being rewound, then remains on continuously when the
beginning-of-tape (BOT) is reached.
3.1.3.5 Unloading Tape
To unload a tape from the drive, do the following:
1. If the tape drive is on-line (the ON LINE indicator is lit), press the ON
LINE switch once to place the drive off-line.
2. Press the UNLOAD switch. The UNLOAD indicator blinks while the
tape unloads. When the unloading process is complete, the UNLOAD
indicator lights continuously, and the front door is unlocked. Atypical
unload sequence from BOT takes 15 seconds.
3. Open the front door and lift the tape reel out of the tape drive.
4. Close the front door.
3.1.3.6 Restarting the Tape Drive
The TS05 shuts down when there is a power failure, or when it detects a
hard error condition. You may need to restart the system in either of these
cases.
When power is interrupted, the drive automatically shuts down and tape
motion stops without any damage to the tape. When power is restored, the
TS05 powers up in the Unload mode. You must press either the LOAD or
the UNLOAD switch, depending on what you want to do with the tape.
Follow the instructions in the previous sections for loading or unloading the
tape.
When the TS05 encounters an error condition from which it cannot
automatically recover, it stops tape movement and displays a series of blinks
on the indicators. If this happens, switch off the TS05 power, switch it back
on again, and then press the UNLOAD switch. After the UNLOAD indicator
stops blinking, remove the tape and call your DIGITAL service representative.
