For most maintenance you need to do on physical hardware in the Collage environment, you simply make your changes (e.g, add memory) and move the node from the Collage maintenance pool back to the Collage discovered pool. Collage then makes the node available for use. However, if you are replacing the motherboard or the primary boot NIC on the node, you need to follow a slightly different procedure. The reason is, Collage may think that it has already discovered that node and won't re-discover it to bring it into the free pool. So, if you've got a node with an unhappy mobo or you are replacing the primary boot NIC, here's what you need to do.

1. Log in to the Collage Controller.
2. Find the node in question and click the checkbox next to it.
3. Select Node Actions > Delete Node:
   
   This removes all knowledge of the node from the Collage database.
4. Replace the motherboard.
5. Power the node on again.
6. Collage discovers and inventories the node as if it were a new node being added to the environment.
   

Remember, for most maintenance, you don't need to go through the step of deleting the node from Collage. Just make your changes and move the node back into the discovered pool. If replacing a motherboard or primary boot NIC, however, you need to also delete the node from Collage.
