Preparing Cartridges
A-10 Tenth Edition 9871
Setting the File Protect Selector
The following information applies to file protecting cartridges (3480, ETape, or
EETape) used in either 4xxx or 9490 tape transports (drives).
Set the cartridge to read-only (file protected or write protected). The drive can
not write data on the tape.
• Turn thumbwheel on the 3480 cartridge until a white dot in a dark
background appears on the thumbwheel, as shown in Figure A-13.
• Turn thumbwheel on the ETape cartridge until a locked padlock appears on
the thumbwheel, as shown in Figure A-14 on page A-11.
• Align the arrow under the locked padlock (Figure A-15 on page A-11).
Set the cartridge to write enabled. The drive can write as well as read data.
• Turn thumbwheel on the 3480 cartridge until the white dot above the
thumbwheel disappears, as shown in Figure A-13.
• Turn thumbwheel on the ETape cartridge until the padlock above the
thumbwheel disappears, as shown in Figure A-14 on page A-11.
• Align the arrow under the open padlock (Figure A-15 on page A-11).
This setting is recommended when entering cartridges into the LSM.
Note: Some software has a feature called virtual thumbwheel, allowing read-
only access to a cartridge that is not physically write protected.
