EEPROM and Firmware Upgrade
The MXH932 design uses a microcontroller to implement the PCIe CMI protocol and other maintenance functions. Dolphin may
from time to time publish updated firmware for the microcontroller, PCIe switch or EEPROM data for the card.
WARNING
: Please note that standard Microsemi tools (ChipLink) cannot be used to upgrade the firmware as this will violate the
warranty. Please contact Dolphin for instructions on how to upgrade the MXH932 firmware.
Note:
Please consult the MXH932 firmware release note for details on supported configurations.
Identifying the Card
The card has a label-
sticker with the serial number in the format ‘
MXH932-YY-
ZZZZZZ’, where YY de
notes the card revision (e.g. BB)
and ZZZZZZ denotes the serialized production number (e.g. 012345)
–
this whole string makes up the serial number of the card (i.e.
MXH932-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
# lspci | grep “Device
4036
”
