Controller module
The top slot for holding controller modules is designated slot A and the bottom slot is designated slot B. The face plate details
of the controller modules show the modules aligned for use in slot A. In this orientation, the controller module latch shown at the
bottom of the module and it is in a closed/locked position. The following figures identify the ports on the controller modules. See
12 Gb/s controller module LEDs on page 24 for LED identification.
The Converged Network Controller (CNC) ports on the 4-port FC/iSCSI controller module can be configured with 16Gb/s FC
SFPs or 10 GbE iSCSI SFPs.
