Card cage and controllers
The library card cage The library card cage is located in the top of the library
cabinet, above cluster 0. It houses up to six FC interface controllers (e2400-160)
or native FC interface controllers (e2400-FC 2G), the library robotics controller
(e1200-160), a fan, and two power supplies (see Figure 7).

e2400-160 FC and e2400-FC 2G interface controllers
The FC interface controllers translates the Fibre Channel Protocol (FCP) to and
from the SCSI protocol, if necessary. It transfers commands, data, and status
information to and from FC controllers and FC and SCSI devices.
Supported devices include:
■ Initiator devices – FC hosts
■ Sequential access devices – tape drives
■ Changer devices – tape libraries
The e2400-160 FC interface controller provides bidirectional connectivity for
Ultra-3 SCSI buses in a Fibre Channel Switched Fabric (FC-SW) environment.
The e2400-FC 2G interface controller provides fibre connectivity for native FC
drives, such as the Ultrium 460-FC drive.
