Replacing a Storwize V7000 Gen2 compression-accelerator

Use this procedure to replace a faulty compression-accelerator with a new one received from customer replaceable unit (CRU) or field replaceable unit (FRU) stock.

Procedure

  1. Complete Procedure: Removing a node canister to remove the faulty compression-accelerator.
  2. Follow the Procedure: Removing and replacing the lid of a Storwize V7000 Gen2 node canister to remove the lid.
  3. Locate the faulty compression-accelerator in slot 1. Slot 1 is next to the two host interface adapters in slot 2 and slot 3.
  4. Gently pull the faulty compression-accelerator upwards to disconnect it and then carefully remove it from the canister.
  5. Remove the replacement compression-accelerator from its package.
  6. Set the connecting edge of the replacement compression-accelerator on the connector so that the connectors are aligned.
  7. Ensure that the compression-accelerator is perpendicular to the canister main board. Align the small tab on the top of the bracket with the alignment hole in the top edge of the slot.
  8. Maintain alignment while you apply pressure to the top edge of the compression-accelerator opposite the connecting edge to push the compression-accelerator into the connector.
  9. Check that the compression-accelerator is installed squarely in its slot. If the small tab of the mounting bracket is not positioned correctly, repeat steps 6 onwards to install the compression-accelerator correctly.
  10. Replace the canister lid, as described in Procedure: Removing and replacing the lid of a Storwize V7000 Gen2 node canister.
  11. Reinstall the canister in the enclosure from which it was removed in step 1 following the Replacing a Storwize V7000 Gen2 node canister procedure.
  12. Reconnect the cables to the canister and ensure that the cables go into the same ports from which they were removed in step 1.
  13. When the canister is back online, check the event log for any new events that relate to hardware changes.
