1. Remove all drives from the defective library (see Figure 10-16) and install them
in the same positions in the replacement library enclosure.
a. Ensure that the power cord is unplugged from the power source for each
power supply in the defective library enclosure.
b. On the rear of the defective library, loosen the blue captive thumbscrews on
the drive sled.
c. If necessary, remove the conductive tape from the drive sled.
d. Pull back on the tape drive handle to remove it from the library.

tab that is located underneath the lower right corner of the lowest drive
sled position. Ensure that the black pull-out tab remains extended when a
drive sled is inserted in the lowest drive position in the library.
Important: If this procedure is not followed, damage to the connector pins
can occur.
f. Place each tape drive into the replacement library enclosure in the same
drive slot as it was positioned in the defective library.
v While the drive assembly is supported, align the drive sled with the
groove in the drive slot rails.
v Slowly push the drive sled forward until it is properly seated.
g. Tighten the captive thumbscrews until the drive is secure.
h. If a drive sled without ESD springs is installed (see Figure 10-16), apply
conductive tape as shown in Figure 10-17 on page 10-18.
