The motherboard for the HPE StoreOnce 3100 System, HPE StoreOnce 3500, and 5100 System is the
standard DL360/DL380 Gen9 motherboard, spares part number 775400-001.
See the
DL360p Gen 9 Maintenance and Service Guide
and
DL380p Gen 9 Maintenance and Service Guide
for more information about replacing the motherboard.
IMPORTANT:
There is a default boot mode setting on the system maintenance switch on the motherboard, which must
be set to Legacy and not be UEFI mode enabled (the BIOS/RBSU boot mode setting is also set to
Legacy).
The following drawing shows a ProLiant DL380 motherboard; the location of the System Maintenance switch
is the same for the ProLiant DL360 motherboard. The default value for all positions on the System
Maintenance switch is OFF. The S7 position must be set to ON for HPE StoreOnce systems.
