Needed to perform manaul upgrade on ELM as it's version was not compliant with the ESM version.
boot from system rescue CD
copy upgrat.tgz to /usr/local/NitroGuard
After upgrade I had engineer logon with the monitor and keyboard still attached as I need to have them reset to the factory password.
after inputing the password the engineer receives a screen with selections rather than a command prompt.
I had them try the alt-f1, alt-f2, alt-f3 but nothing.
I am unable to establish an SSH session from the ESM nor can I ssh via putty.
Looking for some assitance.
You should try to add the device from the ESMI(GUI) if that doesnt' work alt+f2 will switch from selection menu to the logon screen.
Anyway while you are on the selection screen try to check the ip addressing as it might be lost.
