Access Expansion Module
An AEM has a large cartridge access door used for bulk loading and unloading of
cartridges. Additionally, two AEMs may be used to support the redundant robotics
feature. A sliding safety door sections off a defective robot, allowing a service
representative to access the disabled robot while the library remains online.

Configuration Options

Each AEM supports bulk loading and unloading of up to 234 cartridges (see
"Cartridge Access Ports - Bulk Load"
ends of the library. An AEM cannot be installed directly to the left of the Base module;
there must be a module in between. AEMs and PEMs cannot be installed in the same
library. Configuration options include:
Single AEM for bulk load capabilities only. You should install a single AEM on the
■
left for an additional 104 storage slots (see
Dual AEMs for bulk load and redundant robotics support.

Electronics Control Module
The electronics control module (ECM) is responsible for electronics control, robot and
drive control, and host connectivity. The ECM is located in the rear of the Base module,
its main controller cards are the HBCR (library controller) and HBT (drive controller).
