Software Upgrade
During a COM46 software upgrade sequence the card will upload the new image from the IP
address set in the ‘Server_IP_Address’ field for a software upgrade.
The new SW image is then tested to verify it is a valid COM46 image and finally written to the
card’s flash memory. Normal operation of the cards continues during this part of the upgrade
although the LEDs will begin to flash the “SW Upgrade” message pattern while the flash is
being reprogrammed.
DO NOT turn off power or unplug a card that is updating its SW image. YOU WILL
create a doorstop.
During the upgrade process, the status can be determined by evaluating the LED states
according to figure 70 below.
