Ethernet Expansion
Blades 1
Ethernet Expansion Blades (EEBs) are addressed first by module and then
by EEB bay within the expansion module9U Library Expansion Module.
The blade bays within a module are numbered from top to bottom. The
blade bay is always on the bottom of the unit. A one-based numbering
system is used. The full address of a an EEB blade bay is in the form of
[module,EEB]; for example: [1,2], [-1,2].
Power Supplies 1
Power supplies are addressed as [module,PS#], where PS# is 1 for the left
power supply and 2 for the right power supply. The PS# is also etched on
the module chassis, above each power supply.
Understanding Logical Element Addressing
The library uses standard industry conventions to logically number every
storage slot, I/E station slot, and tape drive in the library. Host software
is designed to understand this addressing system, and generally there are
no problems relating to tape cartridge slots. However, hosts sometimes
have problems relating to tape drives, particularly when tape drives,
library control modules, or library expansion modules are added or
removed, or empty tape drive slots exist. This section explains how the
library logically addresses tape drives and slots, so that you can avoid
common problems with host software.
Tape Drive Logical
Element Addressing 1
Tape drive logical element addresses are assigned by partition. The
numbering is sequential within a partition and starts over with each
partition. The addresses start with the lowest library module in a
partition. The top tape drive in the module and partition is always
number 256. The tape drive beneath that is 257, and so on until all tape
drives in that module/partition have been accounted for. Numbering
Note: The logical element addressing described in this section is
different from the library-specific location coordinates
described in Understanding the Location Coordinates

page 32.)
