General Fibre Channel configuration diagram
Refer to the following diagram and note the differences between a SBCEFCSW Fibre Channel
installation and other Fibre Channel installations:
The Expansion Card contains two virtual adapters on a single card. One virtual adapter is connected
to the Fibre Channel Switch Module in I/O module bay 3 and the other virtual adapter is connected
to the Fibre Channel Switch Module in I/O module bay 4.
One or two 16-port switched (Fiber Channel Switch Modules) can be installed in the SBCE chassis.
14 of the ports are internal ports and the remaining two are external ports.
The HBA (Expansion Card) and the switch (Fibre Channel Switch Module) have internal
connections through the mid-plane of the SBCE chassis. No SFPs or cables are required for this
connection. External Loopback testing is not supported on the internal ports.
