5.6 Update the CRS-300 Switch Firmware
Make sure to operate the CRS-300 and all installed modems with the latest
available firmware.
The CRS-300 1:10 Redundancy Switch is factory-shipped with its latest version of operating
firmware. If you need to update the Switch firmware, you may download the update from the
Comtech EF Data Web site (
www.comtechefdata.com). You may also receive the firmware
update archive file via e-mail from Comtech EF Data Product Support.
You may perform the firmware update, without opening the CRS-300, by directly connecting a
user-supplied Microsoft Windows-based PC to the “Remote Control” connector located on the
CRS-230 System Controller Card.
Do these steps:
• Download the firmware update archive file via the Internet to the User PC.
• Once the firmware update is extracted from the transferred archive file, execute the update
process via use of the supplied CCCFlash.EXE Utility Application.
