Chapter 12 Installing, Removing, and Replacing
Adding 9U Library Expansion Modules to an Existing Library
Dell PowerVault ML6000 User’s Guide 264
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 a 9U Library 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 9U Library
Expansion Module above.
Note: The rear Y-rail is impossible to lift up with the tape drives
installed.
