SMC Networks 7401BRA Resetting 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.
