VCS Expressway error

[Valentin Ichim]

Hi,

I have an issue with a VCS Expressway. I have no connection and the error on the front LCD is : "Missing LAN:eth3 "

Do you have any idea of this error ?

Thank you !

Front Alarm LED is off. No change after reboot or shutdown. Any idea before sending a message to TAC ?

Valentin,

I'd recommend that you connect a PC to the serial console of the VCS, shut down the VCS and boot it up again while logging the output of the serial console and provide this log file to TAC for further analysis.

Hi Andreas,

I sent the serial log to TAC and the decision was hardware failure, so it will be proccessed a RMA.

Thank you for your help even I would preffer to receive a technical reson of this hardware failure from TAC.

I just had a similar case with a VCS, MISSING LAN:eth3 and e1000e - The NVM Checksum Is Not Valid, all we did was create a bootable FreeDOS USB with rufus, unpack the PREBOOT.EXE on it, then boot the VCS with the USB and run the following command “bootutil.exe -NIC=3 -DEFAULTCONFIG” on the third NIC which was the faulty one.
