50 CCM4850 Installer/User Guide
Server FLASH command
The Server FLASH command updates the CCM appliance program images in FLASH memory. You
may wish to use this command to update the program with new features or to install a later release.
There are two program images that you may update in the CCM appliance FLASH. The boot image
file (ccm50bt.img) contains the CCM appliance startup and self-test logic. The application image
(ccm50app.img) contains the program that provides CCM appliance functionality.
You will need a TFTP server. Download the latest FLASH image from the Equinox web site,
www.equinox.com, and save the image file to the appropriate directory on the TFTP server.
NOTE: Powering down a system in the middle of a boot FLASH update may render the unit inoperable. To
update the bootstrap, it is recommended that the unit be placed on a UPS under controlled conditions to avoid
interruption of the boot FLASH update process.
