Tape Drive Head Cleaning Procedure
The following procedures should be used to clean the PBX Tape Drive(s).
A Tape
Drive should be cleaned once every three months
to reduce the risk of losing
information and to prevent unexpected service calls. An entry should be made in
the Lucent Preventive Maintenance Log when this is done (see Chapter 6).
A DC2000 Series Data Cartridge Tape Drive Cleaning Kit from 3M is used to
clean the tape head and the tape capstan. This kit consists of a Cleaning
Positioning Cartridge and 20 cleaning wands (Comcode 406622464 or 3M
Reorder number DC051111-12947). A refill kit of 20 cleaning wands is also
available (Comcode 406622472 or 3M Reorder Number DC051111-12948).
NOTE:
The cleaning wands are flammable. Dispose of properly.
1. Busy out the Tape circuit pack using the
busyout tape c
command where
c
is the carrier number (a or b). This prevents background maintenance
tests and other application software from trying to access the tape.
2. Eject the Tape Cartridge from the Tape circuit pack (TN1656). Insert the
Cleaning Position Cartridge into the Tape Drive with the
label side to the
left
(see Picture 1).
3. Prepare the cleaning wand for use as follows: Hold the bristle end down,
crush the wand at the "x" area and squeeze to release fluid and saturate
the bristles.
4. Insert the wand into
R/W Head Slot
(top of cartridge, see Picture 2) with
gentle twisting motion. Stop when solid resistance is felt. Rotate the wand
6 turns while raising and lowering end of wand.
5. Remove the used wand and discard.
6. Prepare a second wand as described in step 3 above.
7. Eject the Cleaning Position Cartridge out of the Tape circuit pack and
reinsert it. This will condition the tape drive to move the capstan when the
cleaning wand is inserted in the next step.
8. Insert the wand into the
Capstan Slot
(middle of cartridge, see Picture 2)
within 10 seconds after the Cleaning Position Cartridge was reinserted.
9. Apply a gentle forward pressure to the wand for about 15 seconds. You
should be able to feel the capstan moving.
10. Remove the used wand and discard.
11. Eject the Cleaning Positioning Cartridge and insert the PBX Tape
Cartridge back into the Tape Drive.
NOTE:
After the Tape Cartridge is inserted back into the Tape Drive, it will
run through a retension pass which will take up to two minutes to
