16 DescriptionFigure 8 Library Control BladeFC Input/Output BladesExpansion modules support optional FC Input/Output (I/O) blades that provide connections for FC tapedrives in the library. Each FC I/O blade has an embedded controller that provides connectivity and featuresthat enhance the performance and reliability of tape drive operations. I/O blades also aggregate FC tapedrive connections, reducing switch port and cabling requirements.Each FC I/O blade has six auto-negotiating, 4Gb/s FC ports and backplane connections. The I/O bladeprovides two host communication ports and four connection ports to FC drives. Each I/O blade is cooled bya fan blade that is installed next to the I/O blade in the expansion module. I/O blades and fan blades arehot-swappable.FC I/O blades cannot be installed in the 5U control module, so your library configuration must include atleast one expansion module to include I/O blades. Any FC tape drive in the library, including drives in thecontrol module, can be connected to an I/O blade in an expansion module. Each 9U expansion module canhouse up to two I/O blades. Depending on the number of installed expansion modules, the library cansupport from one to four I/O blades. No library configuration can contain more than four I/O blades. Any FCdrive in the library, including drives in the control module, can be connected to an FC I/O blade in anexpansion module.1 LEDs (blue, amber, green)2 Gigabit Ethernet (externalnetwork) port3 Ethernet I/O blade control ports(inactive if I/O blades are notinstalled)4 Service Ethernet port5 Service serial port45123
