Control Module (3576 Model L5B)
All library configurations include the control module (
6
in Figure 2-1 on page
2-2). The control module contains the robotics, library control blade (LCB), and
touch screen display. The control module also contains an I/O station, fixed
storage slots, tape drives, and at least one power supply.
The control module can contain one or two tape drives and one or two power
supplies. At least one power supply is always required.
Expansion Module (3576 Model E9U)
Each 9U expansion module (
8
in Figure 2-1 on page 2-2) is a supplementary
module that is attached to the 5U Control Module. Like the control module, the
expansion modules provide fixed storage slots, tape drive slots, and power supply
slots. The I/O station in an expansion module can be configured as storage.
If an expansion module contains only cartridges (no drives), all power is derived
from the control module.
I/O Station
I/O Stations (7 in Figure 2-1 on page 2-2) are located on the front panel of the
library and enable the importing and exporting of cartridges without interrupting
normal library operations. A control module I/O Station has a capacity of six
cartridges. A 9U expansion module I/O Station has a capacity of 12 cartridges.
Note:
This library reads bar code labels to identify the specific cartridges in each slot.
Ensure that all cartridges placed in the library have appropriate bar code labels.
When an I/O Station slot is assigned to a logical library, only that logical library
can access that slot. The I/O Station is shared among all logical libraries, but the
I/O Station slots are owned by one logical library at a time.
In a 5U library, the six I/O Station slots cannot be configured as storage. In a
library that has expansion modules, the I/O Stations can be configured as follows:
