Replacing a node canister memory module

You can replace a faulty node canister memory module with a new one received from CRU / FRU stock.

1. Follow Procedure: Removing a node canister to disconnect and remove the node canister with the faulty memory.
2. Remove the lid of the canister, as described in Procedure: Removing and replacing lid of a node canister.
3. Locate the DIMM slot containing the faulty DIMM:
   Slot 1 is next to the CPU. Slot 2 is next to the battery area.
4. Remove the faulty DIMM by applying gentle, outwards pressure simultaneously to the retaining clips located at each end of the DIMM slot, until the DIMM is levered out of the slot.
5. Touch the replacement DIMM packaging onto a metal area of the case, then remove the replacement DIMM from its package.
6. Ensure that the retaining clips of the DIMM slot are open.
7. Gently place the DIMM in the slot, ensuring the notches in the DIMM align with the shape of the slot (Installing a DIMM).
8. Apply even, firm, downwards pressure on the DIMM in its slot until the retaining clips move inwards and engage the edges of the DIMM.
9. Ensure the retaining clips are fully engaged with the edges of the DIMM.
   Gently pull the DIMM upwards and ensure it does not become dislodged.
10. Replace the canister lid, as described in Procedure: Removing and replacing lid of a node canister.
11. Reinstall the canister into the enclosure from which it was removed in step #v3700_rplc_nodecan_dimm/remove_node_canister.
    The node canister starts.
12. Reconnect the cables to the canister, ensuring cables go into the same ports from which they were removed in step #v3700_rplc_nodecan_dimm/remove_node_canister.
13. When the canister is back online, check the event log for new events, particularly those relating to hardware changes.
