IOAM Enclosure ServerNet Pathways
This drawing shows the ServerNet communication pathways in the IOAM enclosure.
Optic lines connect the ServerNet PCI adapter cards in the blade elements with the
4PSEs in each IOAM module. The 4PSEs in IOAM module 2 communicate with the X
ServerNet switch board. The 4PSEs in IOAM module 3 communicate with the Y
ServerNet switch board. Each ServerNet switch board communicates with the FCSAs
and G4SAs located in IOAM module 2 and IOAM module 3.
