Step 10 Boot the full image (if available) from the media card or from the TFTP server.
If the full image is not available, boot the helper image from the onboard boot flash. After booting the router prompts for an initial configuration dialog.
Step 11 If you need to access the TFTP server to obtain the full image or the saved configuration files, enter the configuration dialog and provide the information necessary to access the TFTP server.
If you booted the full image, restore the startup configuration and running configuration information, and set the boot variable for the new image. The upgrade is now complete.
4.The redundant PRE2 boot sequence is similar, except that the STATUS LED remains off and the final message is IOS STBY, indicating that the PRE2 is in standby state.
If this sequence does not occur, the STATUS LED is off, or the FAIL LED is yellow, check the following:
1. | Are the LEDs on other modules on? If not, |
| check for a problem in the power subsystem. |
2. | If other module’s LEDs are on, remove the |
| PRE2 from the slot, check for bent or broken |
| pins on the connectors, and reinsert it. Ensure |
| that there is solid contact with the backplane |
| and that the PRE2 is securely locked in place. |
3. | Verify the status of the PRE2 module’s internal |
| Ethernet interface (ethernet0/0/0). If this |
| internal interface is down, it could indicate |
