Description
This message is used when a user application wants to obtain information about a DSI SS7MD Board. This can happen at any time after the board has been reported as being present in the system. Typically, in PCI address mode (see ssd_mode below), this message may be sent by the user application to the ssdm module at system startup to determine the serial numbers of boards present within the system.
In the Serial number address mode (see ssd_mode below) this message may be sent by the user application to determine the serial numbers of boards present in the system either via their logical geographic address (see Section 8.7.1, “Geographic Addressing” on page 173) or their physical address (see Section 8.7.1, “Geographic Addressing” on page 173).
Parameters
The SSD_MSG_BOARD_INFO message includes the following parameters:

•board_id
The board_id should be set to the logical board number or alternatively, if geographic addressing is enabled, to the board’s physical address (see Section 8.7.1, “Geographic Addressing” on page 173).
•ssd_mode
Specifies the geographic address mode in which the ssdm module is running. This was specified at system start-up.
The geographic address modes values are:
—1: PCI address mode
—2: Serial number address mode
•board_type
The board type. For DSI SS7MD Boards, this parameter is set to 16.
•serial_number
The serial number of the board.
52
