Firmware Download Feature
Firmware Download allows new firmware to be downloaded 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 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). See FW-DWNLD (Firmware Download)
on page 1298 for more
information and for the firmware download procedure.
