# Configuring SDI video routers
<a name="conductor-live-config-sdi-rou"></a>

If your AWS Elemental Conductor Livecluster deployment includes a router for handling SDI inputs to Elemental Live nodes, you must configure the router in the cluster.

If SDI video inputs connect directly to the Elemental Live node with a cable, see [Adding SDI input devices](conductor-live-config-sdi-dev.md). 

**Rules for routers**
+ The cluster can include only one SDI router.
+ That router can serve several Elemental Live nodes. 

If you try to set up a second SDI router, the configuration of the second router will fail in [Step D: Complete the Router Input Mappings](sdi-rou-input.md).

**Where to perform the configuration**

Make sure you perform the configuration on the correct nodes.


****  

| Node | Work on this node? | 
| --- | --- | 
| Primary Conductor Live node | You configure the router from the primary Conductor Live.  | 
| Secondary Conductor Live node | No. | 
| Worker node | You physically connect the router to each Elemental Live node that will use it.  | 

**Warning**  
If you forget to configure the router, everything looks acceptable on the event or profile, but when you run the event, you receive a no input detected error.
