When prompted for the password, press the clear button and hit enter. This will let you into the switch.
Next to clear the config, type "erase startup-config" at the # prompt, then follow the prompt to reboot the switch.

Bought car at auction- no keys. Had key made at GM dealer. Programmed key- key works. Car wont start- Codes are P0633 and P1629. cannot clear codes


DTC P0633 : Theft Deterrent Key Not Programmed

When learning the pre-release password, as well as the challenge and response sequence, the engine control module (ECM) is placed in learn mode. DTC P0633 will set automatically as an indicator that the system is in learn mode and not as a fault indicator. Once the password and challenge/response are learned, learn mode will be exited when the engine is successfully started. At this point, the DTC will be cleared. If the ECM does not exit learn mode, P0633 will remain current and indicate a fault.
The "key" referenced in the DTC descriptor does not refer to the vehicle key. In this case, "key" is referring to the challenge response.
DTC P0633 requires a successful engine start to exit the learn procedure and clear the DTC. If an unrelated malfunction exists that causes engine starting to be disabled or otherwise unavailable, learn mode will not exit and DTC P0633 will remain current. In this situation, the cause of the inoperative engine starting must be corrected before diagnosing DTC P0633.
DTC P1629: Theft Deterrent Fuel Enable Signal Not Received
The theft deterrent module (TDM) sends the pre-release password to the engine control module (ECM) via the serial data circuit. The ECM then sends a challenge to the TDM. Both the ECM and TDM perform a calculation on this challenge. If the calculated response from the TDM equals the calculation performed by the ECM, the ECM will allow vehicle starting.
DTC P1629 is an indicator that the challenge response was not received within the required 2 second window. This does not necessarily indicate a fault is present with the TDM or ECM. Factors such as a long engine crank, a delay in the serial data communication, or B-codes set in the TDM will cause DTC P1629 to set. This DTC should not be used as a fault indicator, but rather as a symptom to assist in the diagnosis of these other systems.
Who checked the codes , you -dealer ? You need to have BCM checked for codes B - codes ! you need a up scale diagnostic scan tool for that , dealer Tech -2 !

14. If you type "summary" you will see all the switch details.

Amongst these details are the IP address of the switch. If you have DHCP on your network this switch is connected to it will receive one as in my case below, so I can now configure the rest via a web browser.

If not you can use the "ipsetup" command to set a static management IP and access via a web browser.

15. Once you can access the web management page for the switch make sure you set a strong password for "admin" and store it in a secure encrypted location for next time.

16. Don't forget to save your new configuration! Otherwise the switch will be at factory defaults if the power goes off!!

First of all you may try to check the adapter settings on your computer.

Start>control panel>network and sharing center>adapter settings>check status of broadband(should be connected)

If not right click on broadband connetio and click on connect if still showing as disconnected

You may also check internet option settings.
open IE>tools]nternet options?>connection tab>tick on never dial a connection.
Click on LAN settings tick on automatically detect settings>ok

You may also check for the if the driver for your wireless broadand is working by checking it on device manager.

Try to check if broadband is working on the other computer.

How can I know my router's security password?


Not quite clear as to your problem. Are you trying to access the web-based configuration page for the router (for which you need an administrator password)? Or are you trying to make a wireless connection to the Internet via the router (for which you need the wireless security key)?

Those are two separate passwords, and you may be able to retrieve them both. The administrator password would be stored in the computer that was used to configure the router. The security key should be in the computer which configured the router, as well as any computer which made a wireless connection to the router.

If the passwords are stored, you should be able to retrieve them by installing some additional software.

For the computer that configured the router, download and install this program:

For a laptop that connected to the router, download and install this program:

I need to know how to configure link proof radware


Hi Nalinfrancis,

One way you can config the LP is to log on to the serial interface and then configure an IP address to the first eth port that is available. Then connect directly to the port using a crossover cable depending on the laptop or pc that you use if it can switch put your laptop/pc on the same network that you configured on the port. Then connect via your browser to the IP address assigned to the LP. Logging with you default username and password. From there you can do all the configuration via the web interface.

Faulty DFL-700 image - missing FWCore.cfg


Possible problems:
1. IDE Flash device is damaged
2. IDE controller is damaged
2. Firmware is corrupt

Try and download the firmware, and install. You should then get a better idea if the IDE device or controller is bad if it won't install or see the device.
