Capacity expansion feature for Model L32
This topic explains the capacity expansion feature that offers increased storage slots for 
Model L32 of the TS3500 Tape Library.
The Capacity Expansion feature (feature code 1603) is a license key that lets you enable the 
storage slots inside the front door of Model L32 of the TS3500 Tape Library. With the 
Capacity Expansion feature installed, the library offers 140 additional slots for Ultrium tape 
cartridges in the Model L32 if the second I/O station is not present and 88 additional slots if 
the second I/O station is present. The Capacity Expansion feature is required when you add 
one or more expansion frames to the base frame.
When you purchase your library, you may specify that the Capacity Expansion feature be 
installed at the factory, or you may order the feature later and have your IBM Service 
Representative install it. To order the Capacity Expansion feature, contact your IBM Sales 
Representative.
