C9800 Physical Hardware

[tppatrick1]

Good day, all,

I have a C9800 physical hardware - Is it normal for one of the LED lights to be RED? I have attached a photo. The LED has an alarm symbol. I have configured the WLC but after setting the console password, I am unable to login using the configured console password. Even with the configured local username and password, the console does not take it.

I have attached the photo of the LED and the current WLC config.

Config Registry 0x2142 means the router or WLC will ignore the config and boot into ROMMON.

@Leo Laohoo 

The config register was 0x2142 because I took these outputs attached while I was recovering the console password. I have configured it back to 0x2002. As I mentioned earlier, every time I configure the console password, I am unable to login via the console as it rejects the configured password. I am not sure why, so for me to give you the outputs that you requested, I had to recover the password first

. 

Thank you

   Hm ,as far as these ports are concerned ; guess normal if they are not in  use and or can these connections be used  effectively , for instance ?
  For the console problem : you say you are unable to login , what does that translate info exactly : authentication error , or other ?
 Also check the controller logs when trying to login using the console (?)

Yes, the interfaces should be working, though I haven't plugged anything into them. I think what we are seeing on the alarm status is because nothing is plugged into the ports.
