Firmware Upgrade
The PXH820 design uses a microcontroller (BMC) to implement the PCIe CMI protocol and other maintenance functions. Dolphin
may from time to time publish updated firmware for the microcontroller or EEPROM data for the card. Please note that standard
PLX firmware tools cannot be used to upgrade the firmware. Please contact Dolphin for more information.
Identifying the Card
The card has a label-
sticker with the serial number in the format ‘
PXH820-YY-
ZZZZZZ’, where YY denotes the card
revision (e.g. CC)
and ZZZZZZ denotes the serialized production number (e.g. 012345)
–
this whole string makes up the serial number of the card (i.e.
PXH820-BB-012345).
You can also get this information using lspci in Linux:
First, identify the devices for the Dolphin Host card:
Then run lspci, and identify the card. It will show up as something like
This
shows the card as revision 0x4242
(hexadecimal values of the ‘
BB
’ letters in the ASCII table), with
the production number
0x00000067 (0000103 in decimal).
