Figure 2 4004 Series CNC controller module with SFP transceiver
The controller module shown in Figure 2 is used instead of the expansion module (item No.6 in Figure 1 )
when the chassis is configured as a controller enclosure, rather than an expansion enclosure. The
transceiver is shown exploded from the IOM in the CNC example. Controller modules equipped with CNC
ports support qualified FC (8 Gbit/s, 16 Gbit/s), 10GbE iSCSI, and 1 Gb RJ-45 SFP options. Controller
modules equipped with HD mini-SAS ports use qualified SFF-8644 external connectors.
