4.1
Updating Firmware via the Internet
TO ENSURE OPTIMAL PERFORMANCE, IT IS IMPORTANT TO OPERATE THE CDM‐750
WITH ITS LATEST AVAILABLE FIRMWARE.
BEFORE ATTEMPTING ANY ETHERNET FTP UPLOAD (SECT. 4.4), BE SURE TO READ
THE IMPORTANT NOTE REGARDING CONDITIONAL FIRMWARE UPGRADE
REQUIREMENTS.
The CDM‐750 Advanced High Speed Trunking Modem is factory‐shipped with its latest version of
operating firmware. If a firmware update is needed, it can be acquired by download from the
Comtech EF Data Web site (www.comtechefdata.com); or from Comtech EF Data Customer
Support during normal business hours via e‐mail or on CD by standard mail delivery.
The CDM‐750 Firmware Update process is as follows:
•
Perform the update without opening the CDM‐750 by connecting the rear panel 'J4 |
MGMT' 10/100 Fast Ethernet port to the Ethernet port of a user‐supplied PC.
•
Download the firmware update via the Internet to the user PC.
•
Transfer the firmware update, via File Transfer Protocol (FTP), from the user PC to the
CDM‐750.
