Firmware Download Feature
The Firmware Download feature enables S8700 Multi-Connect to download new
firmware to one or more UDS1 circuit boards residing in the system. The
download image is copied onto a source (C-LAN) board, using FTP. The image is
then copied to a target board’s flash memory over the TDM bus. The transfer of
the download image from the source board to a target board is done under switch
software’s control. This process is initiated using the S8700 Multi-Connect SAT
interface.
If the firmware download fails for this circuit pack, an error is logged, and an alarm
raised (See Error Type 174 for this MO). Also, see the FW-DWNLD MO for more
information about trouble shooting firmware-download problems.
