3745 - unable to boot as well not logging by console

[gajanangavli]

we have restarted 3745 router , we are not able to access it through console as well not getting connected in LAN.We used control break also.Till hyperterminal screen is blank.

Try opening it up, remove all interface cards, reseat all removable modules, check power cables. If no output to serial console (not even garbage), either the mainboard has failed, or the power supply has.

Router is power up , no output through the console even garbage.We insert 1FE 1R2W card and poweron router and this happen .

on another 3745 it shows

how we can use that cards for the 3745.

[paolo bevilacqua]

The error indicates either bad RAM, or faulty board.

Now I'm sure to understand the sequence. Without modules it doesn't produce any output, but with the NM insered, it produces the error above ?

[gajanangavli]

yes with card it goes in rommon mode .

[gajanangavli]

yes, with card it goes in rommon mode .
