Chapter

Downloading and Broadcasting
Firmware
This chapter describes file transfers using FTP and downloading
firmware upgrades to application modules.
A major feature of the AS3000 architecture is the capability to
update an AS3000 application module by downloading firmware
upgrades to the module’s flash RAM. This method may be used to
upgrade an SCM module or the application modules that the SCM
manages.
Four types of firmware downloads are supported by the SCM Craft
interface:
• Local download: uses FTP to copy new firmware to the RAM
disk on the SCM and then stores it to local flash to upgrade the
SCM.
• Broadcast download: uses FTP to copy new firmware to the
RAM disk on the SCM, then broadcasts the firmware to one or
more other modules in the local node.
• Remote download: uses FTP to copy new firmware to the RAM
disk on the SCM, then directs the firmware to a remote SCM.
The firmware may then be targeted or broadcast to other
modules in the same node as the remote SCM.
• Targeted Download: uses FTP to transfer files to RAM disk and
then retransmission to a specific card.
The download process is illustrated in Figure 6-1 .
