Caution All mandatory settings must be observed in order for the RS-1600-FC-FFX2 system to function correctly.
1.3.3 Loop Resiliency Circuit Input/Output Module (FC-FFX2)
The RS-1600-FC-FFX2 storage subsystem includes an enclosure with rear facing bays which house two
Loop Resiliency Circuit (LRC) I/O modules with integrated Mylex San Array Pro

FFX2 RAID controller.
(see Figure 1–3 )
The FC-AL Backplane incorporates two independent loops formed by Port Bypass Circuits within the LRC
I/O modules.
The plug-in LRC modules have been designed for integration into a RS-1600-FC-FFX2 storage
subsystem, utilizing FCAL interfacing with the host computer system.
Processors housed on the LRC modules provide enclosure management and interface to devices on the
Backplane, PSU, LRC and Ops Panel, to monitor internal functions. These processors operate in a
master slave configuration to allow failover.
