An I/E station is an expansion module designed for customers who have an increased need to import
or export cartridges. An expansion module can have no I/E station, a 24 slot I/E station, or a 72
slot I/E station. The increased capacity is achieved by increasing the overall length of the I/E station
and doubling its width.
The 24-slot I/E station has a capacity of 24 LTO cartridges that are located in four removable
magazines.
The 72- slot I/E station consists of two side-by-side 36-slot I/E stations that can operate as one 72-slot
I/E station or can operate independently. Each 36-slot I/E station provides I/E capacity of 36 LTO
cartridges in six removable magazines.
Library Management Module
The library management module (LMM) controls and manages library hardware and software
components. It enables both SAN-connected hosts and users who access the library using the operator
panel to configure the library, obtain system status information, and perform various library functions.
The LMM contains the management control blade (MCB), the robotics control unit (RCU), and the
library motor driver (LMD), as shown in
Figure 5 .
