15-2 Using the Download Utilities module

Download Utilities purpose and function
The Download Utilities 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
Download Utilities 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 Download Utilities
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 15-1 on page 15-3 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.
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.
