Internal Firmware Addressing Overview

Internal firmware addressing designates physical location using Library, Rail, Column,
Side, Row (L,R,C,S,W).
Library
Always equal to 1.
Rail
Always equal to 1.
Column
Indicates the horizontal location of a cartridge or drive referenced from the center line
(see "Understanding the Center Line"
Positive (+) value indicates right of center line
■
Negative (-) value indicates left of center line
■
Base Module
Contains columns 1 to 6 for data cartridges and 1 to 4 for tape drives.
■
DEM
Contains columns -1 to -6 for data cartridges and -1 to -4 for tape drives.
■
CEM
Contains six columns for data cartridges.
■
Column numbering continues consecutively from the adjacent module. However,
■
if there is no DEM, a CEM placed directly to the left of a Base contains columns -7
to -12 (columns -1 to -6 are skipped).
PEM
Contains only three columns for data cartridges. The outer most three columns are
■
inactive.
AEM
AEM columns are numbered as if a DEM and four CEMS are installed to the left of
■
the Base Module and four CEMs are installed to the right.
Left AEM columns are always numbered -33 to -31.
■
Right AEM columns are always 31 to 33.
■
Side
Indicates the front wall (CAP side) or rear wall (drive side) of the library.
Rear wall = 1
■
Front wall = 2
■
Row
The vertical location of a tape cartridge, consecutively numbered from the top (1)
down (52).
