Introduction
Prevent network loops
7Repeat steps 2 through 6 for the second 1000Base Module, ensuring that the cabling from this 1000Base Module goes to the other Matrix Module.

8Plug the SC connectors on the fiber optic cables into the RX and TX sockets, and connect the other end of the cables to a device or group of switches with redundancy.
9Check the LEDs on the 1000Base Modules to verify the links. For more information on LEDs, see Chapter 2
Link Aggregation with Two Modules
Two modules installed in a stack can be link aggregrated to increase bandwidth between this stack and another device or stack.
Link aggregation must be configured in Intel Device View to prevent a loop. When two modules are installed in a stack and connected to another single device or stack (without redundancy or link aggrega- tion), then a loop may be created. Note that even with spanning tree enabled, a delay of 10 to 15 seconds may occur before the loop is dis- covered.
