# Querying the status of a board

An application can query the status of a CX board. The following information is available:

- Whether various voltage levels are available to power the stations, and ringing at the stations

- The number of subassemblies present

- Whether the board is operating at a normal temperature, or is overheating

- System errors

To query the status of a board, invoke cdiGetBoardStatus. cdiGetBoardStatus returns a CDI_BOARD_STATUS structure containing status information.

CDI_BOARD_STATUS is defined in cdidef.h. Refer to cdiGetBoardStatus for a description of the fields in this structure.
