Downloader purpose and function 
The Downloader module is used to download firmware and FPGA (field 
programmable gate array) code for any number of Elastic system modems. 
These modems are selected by querying the modem database. The 
Downloader module examines the file header when told to download a certain 
file to the modem to verify the authenticity, type, and reliability of the file. 
Downloader monitors and displays the progress of a download and alerts the 
operator if any problems occurred during the download.
Using Downloader
EtherLoop modem firmware upgrades can use either FPGA (field 
programmable gate array) code or modem firmware. The overall process of 
upgrading EtherLoop modem firmware consists of uploading the new 
firmware to the YWS from a diskette or a location on a reachable network, and 
then downloading the firmware to the modems managed by the system YWS. 
Procedure 7-1 on page 7-3 describes the steps required to upgrade the 
firmware and/or FPGA code on a YWS. 
Downloader options
When using Downloader, you will select the following options:
• Database. This is the database where modem MAC addresses are stored. 
Currently, "System Inventory" is the only selection.
• Modem(s) to which you will be downloading or uploading. The 
available MAC addresses for the System Inventory Database include: 
— CO Modems: All of the CO/SE modems available in the currently 
selected database. 
— CPE Modems: All of the CPE/CE modems available in the currently 
selected database. 
• Firmware/FPGA. This is the file containing the firmware for each of 
these firmware types to download to the selected modems. 
• Shelf Devices. Select any shelf devices provisioned.
Downloader status and logs
Downloader’s View Last Status and View Logs functions in allow you to view 
the status of the last download or upload, or view the history log of all 
downloads performed.
CAUTION - Avoid firmware version conflicts
CO/SE and CPE/CE modems can be selected individually or in groups for 
the firmware upgrade. To avoid firmware version conflicts, always upgrade 
modem pairs (CO/CPE) simultaneously. This can be done automatically by 
selecting the option to "Auto-select all modems in the same Server/Client 
group" in the Downloader Main Menu.
