Scalar i500 User’s Guide 348
Unstacking the Existing
Modules 12
Unstack the modules as follows:
1 Starting with the topmost module of your library, open the I/E
station and access doors.
2 If your current configuration already uses an expansion module,
disengage the Y-rails so the modules can be safely unstacked.
a From the front of the library, find the Y-rail release mechanism,
which is located on the left side of the module. Squeeze the
handle of the Y-rail release mechanism, lift it, and release it so
that it locks into place.
b From the rear of the library, find the rear Y-rail release
mechanism located in the interior of the right side of the module.
Squeeze the handle of the Y-rail release mechanism, lift it, and
release it so that it locks into place.
Caution: Before unstacking the modules, the robot
assembly must be parked as described in
Preparing to Install an Additional Expansion
Module above.
Note: The rear Y-rail is impossible to lift up with the tape drives
installed.
