Loading new firmware over the serial console port
You can recover firmware through the serial console port on your console server. The example below shows how to do this from a Windows PC using HyperTerminal and Kermit:
- Download the latest firmware image (such as cm41xx.flash)from ftp://ftp.opengear.com or from http://www.opengear.com/firmware/ and save in a directory on your PC
- Serially connect the unit to the desired com port (COMM PORT 1, 2) on the PC
- Open the HyperTerminal program (HyperTerminal is bundled with Windows 95, 2000 and XP but not Vista, however it can bought from http://www.hilgraeve.com/hyperterminal.html)
- Enter a Name for the new connection to the console server, select an icon and click OK
- Leave every field as is except for the 'connection using' field; select the port on your PC that is serially connected to the unit
- Within the com port settings, set the following:
- Bits per second: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
- You will now need to reset the console server:
- The Hyper Terminal screen should be blank
- With the thin strong object, press and hold the erase button on the unit in while simultaneously turning the unit off with the switch at the rear.
- The console server lights should be off
- Repeat the above step while turning on the unit
- Text should flow onto the HyperTerminal screen as shown below
- Press any key to abort U boot auto-booting, or hit CTRL + C after the brief window where "any key" will suffice
- In the boot command type loadb 0x0400000. The screen should now read:
"## Ready for binary (kermit) download to 0x00400000 at 115200 bps..."
- Click on the top menu 'Transfer' then 'Send File'. In Filename - click browse and navigate to the file location of cm41xx.flash. In Protocol - select Kermit from the dropdown menu
- Click 'Send'. The file will then send and will take around half an hour to complete
- In the command line type gofsk 0x0400000 to complete the recovery
