Power supply bay
The power supply bay accommodates two sets of three power supply modules.
It also contains the AC power connectors and the main AC power switches.
The AC power cord connectors and main AC switches control the power to the
library and its drives. Each set of three power supply modules has its own AC
power connector. The AC switch above the connector turns the main AC power
to the power supply modules on and off.
 The AC connector and switch on the right side of the chassis control power to
the three power supply modules to the immediate left of the connector. If you
are not using 2N redundant power supplies, these modules are typically
installed first.
 The AC connector and switch on the left side of the chassis control power to
the power supply modules installed to the immediate right of the connector.
 Cord locks on each power cord secure the cord to the library to prevent it
from being inadvertently disconnected.
 A permanent ground wire is connected to the power supply bay to ensure
that the library is properly grounded at all times.
Figure 5 The library power supply components (2N configuration shown).
Notes:
 Any bays that do not have power supply modules installed must have covers
installed to maintain proper air circulation throughout the library.
 See Redundant Power Supplies on page 73 for information about using 2N
power supply redundancy.
Media Storage
Chambers
All of the media in the library is stored in TeraPack magazines, each of which
contains ten slots for LTO media or nine slots for TS11xx technology or T10K
media (T380 only). The magazines are placed on shelves divided into
chambers. The number of chambers in the library depends on the type of
library and its configuration (see Data Storage Capacity on page 530).
