Select option 6 to exit to the Main Boot Menu and then reboot the router from there.

  

Be sure to change the baud rate of the console terminal back to 9600 bps, disconnect, and re-
dial if it was changed to speed up the download. Then you can see the system reboot in 
progress. 

Use the following procedure to upgrade the software with TFTP: 

1  You must have level 3 privileges. 

2  In the User View, enter: tftp <server ip address or hostname> get <filename>. 

3  Enter the System View. 

4  Set the router to boot from the new image using “boot main <filename>”. 

5  Exit the System View. 

6  Reboot the router. 

The following example illustrates this procedure: 

 
<MSR-50>tftp 172.16.1.254 get msr50-cmw520-b1508p01-si.bin

Upgrading the application image with the Ethernet SubMenu will use an Ethernet interface to 
download the application. In this approach, the router is the TFTP Client and needs to connect 
to a TFTP Server using a fixed Ethernet interface. The following describes how to upgrade the 
application image with this approach: 

1  Start the TFTP Server on the host connected to the Ethernet interface on the router. Set the 

path for the source file to be downloaded. 

2  In the Boot Menu, select option 3 to enter the Ethernet SubMenu (shown below):
