Returning a Tape Drive CRU to Compaq
Returning a Tape Drive CRU to Compaq
To prevent damage to a tape drive CRU you are returning to Compaq for repair, do the
following before shipping the unit:
1. Before removing power from the tape drive CRU, unload any cartridge loaded in
the tape drive. Do not ship a drive CRU with a cartridge loaded in the tape drive
unless you were unable to remove it.
2. If the drive CRU has an ACL, remove the cleaning cartridge from the ACL before
returning the drive CRU for repair. See Removing a Cleaning Cartridge From an
ACL on page 6-11.
3. If the drive CRU has an ACL, insert the foam packing piece (saved from the
replacement drive CRU) into the ACL autoloader of the drive CRU before packing
the drive CRU for shipment.
4. Use the box and packing materials saved from a replacement drive CRU to pack a
drive CRU for return to Compaq.
5. Any controller logic board, controller BIC, BEB, or adapter should be protected in a
separate plastic antistatic bag and reshipped in the same packing material in which
the replacement component was received, between two layers of foam packing.
6. Call your service provider for shipping instructions.
Replacing a Cleaning Cartridge in an ACL
The ACL is programmed to request a new cleaning cartridge after 100 cleaning cycles.
When the cleaning cartridge needs to be replaced, the ACL displays the following
message:
WARNING!! CHANGE CLEANING CARTRIDGE IN CLEANING CELL
You can replace an old cartridge with a new cartridge by putting a new cleaning
cartridge into the cartridge magazine and pressing buttons on the ACL front panel, as
follows:
1. Press the RESET button to take the ACL offline.
2. Press the UNLOAD button to rewind, unload, and eject the cartridge from the drive.
3. Open the cartridge magazine door, extend the carriage, and lift out the cartridge
magazine.
4. Mount a new cleaning cartridge in the top slot (slot 1) of the cartridge magazine.
Most cleaning cartridges are clearly marked with the number of cleaning cycles
they provide. Use only cartridges from a reputable manufacturer that provide 100
WARNING. Do not attempt to remove a cleaning cartridge from its storage chamber by hand.
Doing so could cause personal injury or damage the autoloader.
