Factory Reset GTS4950-PWR+

RedDirt — Thu, 17 Jun 2021 06:44:18 GMT

Hello all. Well I goofed up in uploading a config to the GTS4950 and now I cannot log back in via the console port. Something broke (that is, was configured wrong) when the Console access user name and password were entered.

I have tried using the CTRL-C option, but do not see anything in there that would allow me to factory reset the switch and start over. I had the thing in a stack of 4 switches too. Our resident Extreme expert will be back in the office in the morning, but I was hoping to get this fixed before then. All I want to do is just factory reset the switch so I can get the configuration put in. Can anyone instruct me on how this might be done?

Are you getting the login prompt when connected via console?

Well, I hit CTRL-Y and it takes me to the login prompt for the console.

Correct. So are you not able to login using the default creds?

User=RW | Password=securepasswd / User=RO | Password=userpasswd

User=RW | Password=secure / User=RO | Password=user

That’s correct. I have the configuration file that should have been implemented, but it did not, for some odd reason, fully accept the console password for either RW or RO. I was on my Linux laptop using Putty and am not fully sure why it did not accept the password provided, but it continued withe configuration anyway and before I realize what was goofed, I had already rebooted the switch.

I have not tried the default credentials you listed as I was not aware of those. I can give those a shot and see, however.

The configuration file does not carry the username/password data. So its obvious that it will not work.

Try the default credentials.

When I spoke of the configuration file, I should have said the configuration I was trying to upload to the switch, but I get what you are saying. I will try the defaults and see if that does the trick.

@Dilraj Singh Khalsa Thank you for your help. It had (the switch) in fact defaulted to those passwords and I was able to get in and reset the switch and start over.
