Daisy chain PXIe Configuration
–
PCIe x8
The host has a MXH932 adapter configured for Transparent Host operation. Two or more MXP924 switches are connected in a
daisy chain. Port P1 and P2 is upstream. Port P3 and P4 is downstream.
The MXP924 DIP-1 Switch should be Config 1: Transparent Target / Daisy chain.

EEPROM and Firmware Upgrade
The MXP924 design uses a Board Management Controller (BMC) to implement the PCIe CMI protocol, reset and other maintenance
functions. Dolphin may from time to time publish updated firmware for the BMC, 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 MXP924 firmware.
Note:
Please consult the MXP924 Firmware Release Note for details on supported configurations.
Identifying the PXIe module
The module has a label-sticker with
the serial number in the format ‘
MXP924-YY-
ZZZZZZ’, where YY de
notes the revision (e.g. BB)
and ZZZZZZ denotes the serialized production number (e.g. 012345)
–
this whole string makes up the serial number of the module
(i.e. MXP924-CC-012345).
