Low level hardware analyze (not for beginners!)

Fault finding on broken hardware

This checks can be preformed if the basic operation of the AMC card is still OK. <br\> First step is to disable the hardware watchdog. If the AlphaCom software is not able to start then the hardware watchdog will continuously reset the card thus AlphaWeb is unavailable.

• If the cards IP address is unknown cold boot the card
• Try AlphaWeb login, if success do an AlphaSys upgrade in case some files is corrupted.

• If still not working do the hardware check listed bellow.

If no AlphaWeb/telnet available enable the Linux console dip switch and use the serial port for further tests.

The following test are done from console login. Super user password required.
