Maintaining RPU or RPU2 Software 47

5: Exit to Main Menu

Enter your choice(1-5):

10 Ignore software check (Boot Menu option a).

When upgrading software, make sure that you are using the correct

software version. If the upgrade still fails and the system displays “invalid

version” in this case, you can use this option. It allows the system to

upgrade software without checking the version of extended Boot ROM

image segment, Boot ROM image, and application image for backward

compatibility. This is a one-time operation, however; the router checks

version again at reboot.

11 Boot from Flash (Boot Menu option b).

12 Boot from the CF card (Boot Menu option c).

13 Exit and reboot (Boot Menu option d).

Upgrading Software

Using Xmodem

You can use the console port to upgrade software using Xmodem

without the need of setting up a configuration environment.

Upgrading the application image

1 From the Boot Menu (refer to the section “Boot Menu”) and enter option

1 to download an application image using Xmodem. The router supports

the following downloading speeds:

Please choose your download speed:

1: 9600 bps

2: 19200 bps

3: 38400 bps

4: 57600 bps

5: 115200 bps

6: Exit to Main Menu

Enter your choice(1-6):

2 Select an option. For example, if option 5 for 115200 bps is selected, the

following message appears:

Download speed is 115200 bps. Change the terminal’s speed

to 115200 bps, and select XModem protocol. Press ENTER key

when ready.

3 Change the terminal baud rate (see Figure 21) to the same baud rate for

software download (115200 bps in this example). After that, select

[Dial-in/Disconnect] to disconnect the terminal, and [Dial-in/Dialing] to

reconnect it. Then, press <Enter> to start downloading. The system

displays:

1 2 ... 42 43 44 45 46 47 48 49 50 51 52 ... 59 60
