EEPROM and Firmware Upgrade
Dolphin may from time to time publish updated firmware for the Board Management Controller, PCIe switch or EEPROM data for
the card. Please contact Dolphin for instructions on how to upgrade the adapter 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 adapter card firmware.
Note: Please consult the adapter card firmware release note for details on supported configurations.
Identifying the Card
The card has a label-sticker with the serial number in the format 'MXH940-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.
MXH940-CC-012345).
You can also get this information using lspci in Linux:
First, identify the devices for the Dolphin Host card:
# lspci | grep "Device 4052"
09:00.0 PCI bridge: PMC-Sierra Inc. Device 4052
09:00.1 Bridge: PMC-Sierra Inc. Device 4052
0a:00.0 PCI bridge: PMC-Sierra Inc. Device 4052
Then run lspci and identify the card. It will show up as something like
# # lspci -s 9:0.0 -v
09:00.0 PCI bridge: PMC-Sierra Inc. Device 4052 (prog-if 00 [Normal decode])
