including license keys, by generating a Support ticket.

Replacing the HP p1228 controller

IMPORTANT: When replacing the p1228 controller be sure to always replace the card into the
same slot from which it was removed. Make sure the card is connected to the SuperCapacitor and
to the external SAS data storage.
Procedure
1. Power off the HPE StoreOnce Backup system and, observing the safety and antistatic procedures
documented in the HPE ProLiant Servers user guides, remove the cover from the HPE StoreOnce
Backup system, as described in the appropriate HPE ProLiant Maintenance and Service Guide.
2. Locate the p1228 controller card and detach the cables connecting it to the SuperCapacitor and to the
external SAS storage. (The StoreOnce 4900 Backup has two RAID cards; be sure to identify which
slot contains the failed card.)
3. Unclip the blue retaining latch on the PCIe card (1 and 2) and remove the PCIe card (3).

4. Move the cache module from the failed p1228 card to the new card in case there is any data that has
not been written to disk. (Do not disconnect the superCapacitor from the cache module.)
5. Install the new p1228 card (1) and check that it is seated properly. Close the blue PCIe card retaining
latch (2).
