Procedure: Upgrading node canister memory

For Lenovo Storage V3700 V2 XP, you can upgrade the amount of canister memory from 8 Gb to 16 Gb. For a Lenovo Storage V5030 system, you can upgrade the amount of canister memory from 16 Gb to 32 Gb.

1. Follow Procedure: Removing a node canister to disconnect and remove the node canister that you want to upgrade.
2. Remove the lid of the canister, as described in Procedure: Removing and replacing lid of a node canister.
3. Locate the DIMM slots:
   Slot 1 is next to the CPU. Slot 2 is next to the battery area. A new stick of memory is added into the empty slot that sits above the stick that is already installed.
4. Ensure that the retaining clips of the DIMM slot are open.
5. Gently place the DIMM in the slot and ensure that the notches in the DIMM align with the shape of the slot.

7. Ensure that the retaining clips are fully engaged with the edges of the DIMM.
   Gently pull the DIMM upwards and ensure that it does not become dislodged.
