Table 1-1 on page 1-10 shows the number of cartridge and tape drive slots available
depending on the type and number of modules installed.
Slot counts are based on the following assumptions:
!
Capacity includes reserved slots for diagnostic and cleaning cartridges.
!
Reserved slots (for cleaning and diagnostic cartridges) are located only in the base
module on the left side as you open the front door. These slots can be configured
for data cartridges if desired.
!
The base module has a 5-slot CAP; the drive expansion module (DEM) and
cartridge expansion module (CEM) each have two 5-slot CAPs. These slots can be
configured for data cartridges if desired.
!
When DEMs and CEMs are installed in the same library, the DEMs are above all of
the CEMs.
When you add an expansion module below an existing module, you increase the
capacity of the module directly above it by:
!
Base module: +16 slots
!
CEM (when another CEM is below it): +10 slots
!
CEM (when a DEM is below it): +7 slots
!
DEM: +7 slots
When a CEM is installed below a base module or DEM, the top two rows on columns
9, 10, and 11 of the CEM are not accessible (-6 slots because of the tape drives).
The lowest module in the rack requires installation of the floor. The floor limits the
distance the robot can travel, which makes the bottom row(s) in the lowest module
inaccessible:
!
Base module: -16 slots
!
DEM: -7 slots
!
CEM (below another CEM): -16 slots (-10 slots on the lowest CEM, -6 slots on the
CEM above it)
!
CEM (below base module or DEM): -16 slots
Cartridge access ports:
!
Base module: 5 slots (one magazine)
!
Each DEM: 10 slots (two magazines)
!
Each CEM 10 slots (two magazines)
