FIGURE 2-6
StorEdge A3500FC controller modules in a loop using hubs.
Note – No other type of fibre channel device should share the same loop or hub
connected to the A3500FC controller module.
Each controller that is connected to a hub must have a unique loop ID. Whenever
you add a second controller to a hub, make sure that the loop ID of the controller
being connected is different from the loop ID of any other controller currently
connected to the same hub.
Refer to Section 2.3 "Setting the Loop ID" on page 2-13 for instructions on setting the
loop ID of a controller.
Caution – Ensure that the controller module IDs are set so that each hub is
connected to A and B controller canisters.
