1. Determine if the system has logical partitions. Go to Determine if the system has logical partitions
before continuing with this procedure.
2. Remove media (if any) from the device. If the eject button on a tape device is failing, go to Tape
cartridge - manual removal, then continue with the next step of this procedure. If the eject button on a
CD-ROM is failing and will not open, go to Optical media - manual removal, and then continue with the
next step of this procedure. If the eject button on a DVD-RAM is failing and will not open, do not
attempt to manually remove the optical media at this point in time.
3. Are you removing a unit by using device concurrent maintenance?
v Yes: Continue with the next step.
v No: Perform the following:
a. Power off the expansion tower. See Power on/off the system and logical partitions.
b. Disconnect the power cord from the expansion tower.
c. Open the front cover. See Models 830/SB2 with FC 9074 - Covers.
d. Pull on the handles which are located on each side of the unit and remove the unit.
e. Install the new device by reversing the remove procedure. After exchanging an item, go to Verify
the repair.
Notes:
– If you need to remove a tape from the old tape unit, see Tape cartridge - manual removal.
– If you need to remove optical media from a DVD-RAM unit, go to Optical media - manual
removal.
This ends the procedure.
4. Before exchanging a removable media unit, you must ensure that the unit is not in use and is varied
off.
Note: If you are removing an optical storage unit you must ensure, that all of the removable media
units in the expansion tower are not in use and are varied off.
