When replacing a unit, you must power the failed unit down, remove and reinstall
the cabling, cover, and feet onto the new unit, and power the new unit on.
Note –
If you are replacing a rackmount unit, unscrew the unit from the shelf, slide
the unit out, and follow the steps below. See Section 1.2.1, “Mounting the
Autoloader,” on page 1-7 for more details.
1. Remove all tapes from the failed unit. See Section 3.2, “Loading/Unloading Tape
Cartridges Into the Autoloader,” on page 3-2.
2. If the failed unit is still powered on, turn the standby (power) switch off, which is
in the bottom left-hand corner when you are facing the unit, and unplugging the
power cord.
3. Remove the cabling and terminator from the back of the failed unit.
4. Remove the cover and feet from the failed unit.
