Chapter 6. FLASH UPGRADING
6.1 Overview
The CDM-710 eliminates the need for updating firmware by physically replacing EPROMs.
Instead, the CDM-710 modem uses ‘flash memory’ technology internally. This makes software
upgrading very simple, and updates can now be sent via the Internet, E-mail, or on disk. The
upgrade can be performed without opening the unit, by simply connecting the modem to the
Ethernet port of a computer.
New firmware can be uploaded to the unit from an external PC, as follows:
• Go online to: www.comtechefdata.com
• Click on: Support
• Click on: Software Downloads
• Click on: Flash Update Files
IMPORTANT
• Refer to Chapter 11 for the Gigabit Ethernet Interface upgrade procedure.
• The user must reflash both images with the same firmware version for the
unit to function properly.
• The upgrade from an earlier version to 4.x.x is a one way upgrade path.
Once an upgrade to 4.0.1 is completed it is no longer possible to revert to
earlier versions. If reflash to an earlier version is attempted the modem will
detect and disallow it as a protective measure. The unit will also disallow an
attempt to switch to an image with an earlier version of firmware.
