8.1.4 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 (see Figure 63). 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 Table 5 below.

Note: The PWR LED may flash briefly at the start and/or end of the upgrade.

If you see a behavior not described above in conjunction with a failure to complete the update, it

may be an indication that something has gone wrong with the update. You should check that you

are following each of these guidelines before attempting another update.

 All system/PC connections are functioning correctly.

 The TFTP server is running on the PC handling the update.

 The TFTP server is fully configured and pointing to the folder containing the update.

 You have entered the correct destination IP for the PC handling the update.
