IPS 4270-20 error codes under the hood 01 and 51

[ebelschner]

I have no console access and no mgnt port access... trying to get into a spare box we have ... I turn it on , and I have no access ??? Is there a special or different DB9 cable I need??? Is it possible the console and mgnt ports have been configured to not allow access , or this unit is DEAD   again I have two error codes on the LCD display one reads 01 then flashes 51 and back and forth  any help thanks all

If your unit has a serial port, you can connect to it in multiple ways. For more details specific to your model, see the following link (steps 5 and 6):
