Smc 7401BRA RESET Manual

Re-Burn FLASH with USB connection/Reset to factory Defaults

1 Power off the CPE, remove case and short the jumper J4. Jumper J4 is

right beside the USB connector.

2 Power up the CPE and connect the USB to a host PC running in pure

DOS environment .

3 Change directory to where you place the USB FLASH burner utility, for

example, C: \SMC7401BRA1.10.
4 Execute the batch file FLASH.BAT
5 Wait for a couple of seconds to complete the FLASH programming. DO

NOT power off the CPE while programming is still on going. If it fails due to

this, just redo it. Note: During the FLASH programming you will be asked

for a Start and End MAC address. Just leave both blank and press enter.
6 After the FLASH programming has completed power OFF CPE. Remove

J4 and power ON. Note: Do not unplug the USB cable for the minute.
7 After power ON leave the CPE for 2 minutes. After 2 minutes unplug USB

cable. You will see the USB LED go out and hear a clicking sound. The

CPE is now updated to the latest firmware & reset to factory defaults.
Notes: If you run FLASH.BAT and the USB fails to initialise try on another

USB port. If this does not work the FLASH utility is not compatible with the
USB controller on the PC. Try another brand PC.

The FLASH.BAT utility is designed to work on a FAT partition. If you execute
from an NTFS partition you may have problems.
