By combining the information from the tables in Understanding Routing Through the Switch, it is possible to determine a route through the switch. This topic describes a sample situation that might occur.
A route is initiated at connector 2B. The left LED (P3) blinks.
Using CXP Connectors and Link LEDs to Switch Chip Port Routes, it is determined that the link routes to switch chip A, through port 36.
The Subnet Manager instructs switch chip A to use port 4 to forward the link.
Using Switch Chip Port to Switch Chip Port Routes, it is determined that the link routes to I4 switch chip E, port 6.
The Subnet Manager instructs switch chip E to use port 12 to forward the link.
Using Switch Chip Port to Switch Chip Port Routes, it is determined that the link routes to switch chip B, port 15.
The Subnet Manager instructs switch chip B to use port 24 to forward the link.
Using Switch Chip Port to CXP Connectors and Link LED Routes, it is determined that the link exits the switch at connector 3B. The right LED (P1) blinks.
