IBM System Storage TS3310, Maintenance Information

Page: 52 / 531

The module digit uses a zero-based numbering system. The control module is
labeled as
0 (zero). The front, left-most column in the module is labeled 1 . The top
slot in each column is labeled
1
. For more information, refer to the sections that
follow.
Modules
Library modules are represented by the first digit of a library coordinate. Modules
are identified relative to the control module (CM). The CM is number
0
. Modules
stacked above the CM are addressed with positive integer digits depending on
their position above the CM. For example, the expansion module stacked directly
above the CM is number
1
. The expansion module stacked directly above module
1
is number
2
, and so on.The module(s) stacked below the CM is numbered with a
negative integer depending on its relative position to the CM. The expansion
module directly below the CM is number
-1
. If there is an expansion module
installed above the CM, it will be nu1.The expansion module stacked
directly below module
-1 is number -2 , and so on.
Columns
A storage column is a group of slots arranged vertically in the library. Columns are
represented by the second digit of a library coordinate. Columns are identified
relative to the front left of the library. The column in the front left of the library is
