Firmware Update Notes

When a new firmware update file is loaded into the router, the following checks are made to insure that the new file is correct.

1. Before the new firmware update is loaded into its permanent location (the NVRAM), it is first downloaded into a temporary (RAM) area for

checking.

2. The downloaded file is first checked against a checksum to insure that the entire file has been downloaded and no data errors have

occurred.

3. Each firmware file is encoded with a special product identification, which must match the current code in the router. If the two identifiers

match the update is allowed to proceed. If either of these checks fail, the firmware update file is rejected and a failure message given to
the user.

4. After the new firmware file passes both of these checks, the code is written to the permanent location (NVRAM). Power to the unit must be

maintained during this critical step; do not turn off unit. As the router writes the new code into the permanent location (NVRAM), the user is
presented with a screen on the browser which counts down for 60 seconds. After the 60-second countdown, the unit automatically reboots
and reinitializes.
