On the SL3000, if you convert two Cartridge Expansion Modules to two Parking Expansion
Modules, how many slots will you lose?
A.
312
B.
440
C.
516
D.
620
Explanation:
The optional Cartridge Expansion Module (CEM) provides additional storage cell
capacity and growth for cartridges only.
Each CEM adds up to 620 data cartridge physical storage cells.
Note: The optional Parking Expansion Modules (PEMs) provide additional storage cell capacity
and growth, as well as space for a redundant TallBot to be “parked.” The parking space makes the
three outer-most columns of storage cells on the front and rear walls inaccessible. The
inaccessible cells can be left out of the module, or they can be installed to allow later conversion of
the PEM to a CEM. PEMs do not include tape drives.
PEMs are only used with the Dual Robotics feature, and they are always installed in pairs. They
must be the last modules on the right and left sides of the library series.
