3. E ach 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. A fter the new firmware file passes both of these checks, the code is written to the NVRAM code area. Power to the unit must be maintained dur-

ing this critical step; do not turn off unit. As the router writes the new code to 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.

6.6.4 firmWare update via

The MBR1000 supports software upgrades via the USB port. A USB mass storage device (thumb drive) is preloaded with the new software .bin file.

• File formats supported - FAT16 or FAT32

•

F ile name format -

u_<product_ name>.bin

• Update steps:

1. Plug in thumb drive to either USB port on MBR1000.

2. If a valid image is found the USB, LED on USB will blink indicating the update file is being read.

3. Once read successfully and validated, the LED on USB will turn solid green.

4. T o initiate the upgrade, the user must unplug the thumb drive. At this point the image will be installed and the unit will reboot. All LEDs turn off

on reboot.

If at anytime during the above process some error occurs that corrupts the upgrade process (e.g., bad file or unplug before the file is fully read), the

WLAN and MDM LEDs on the MBR1000 will blink.
