The TS3500 Tape Library also supports an option for 64 additional I/O slots in a newly
purchased Model D23 or D53 frame. A D-frame with I/O installed includes four
independently accessible I/O stations. The D-frame I/O stations increase the maximum I/O
slot capacity from 32 to 224. There is a maximum of three D23 or D53 I/O frames in a
library. The D-frame I/O stations can double the maximum insert/eject throughput in
libraries with a dual accessor. These D23 and D53 Models are compatible with existing
Models L22, L32, L52, D22, and D32.
Note: The 64 additional I/O slots features (feature codes 1655 and 1656) are not supported
on libraries with mixed media. In order to use this feature, the library must use all Ultrium
media or all 3952 media, not a mixture of both.
Table 1 shows how I/O stations can be mixed among frames.

Notes:
1. The 3592 I/O station for Model L32 is included with feature code 1608.
2. For the 64 additional I/O slots option, feature code 1451 must be installed as a
prerequisite, then either feature code 1655 for LTO Ultrium media, or feature code
1656 for 3592 media. When expanding an installed library, feature codes 1655 and
1656 assume the D-frame is installed at the end of the library string ("end of the
library string" refers to the very last frame in a single accessor library or the last frame
before SBB in HA libraries). If the customer prefers the D-frame to be installed
elsewhere in the string, the Service Representative must obtain a "Services Contract"
to uninstall additional frames as necessary to accommodate the customer's request.
3. Mixed media is not allowed in libraries with D-frame I/O slots. All cartridges must be
either LTO Ultrium or 3592.
4. A maximum of three D-frames with I/O slots can be installed per library.
