Knowledge Is Everything

The model used for this is Extreme Summit x150-48t.As this switch doesn’t have any hardware reset buttons we can go for resetting the configurations using the below method.

Remove the power cable of the switch or power off the switch for 60 seconds.After that switch on and we can see the switch is booting via the terminal window.It will show “Press and hold spacebar to enter BootStrap mode“,we don’t want to enter this mode.Skip this and it will again show “Press and hold the spacebar to enter BootRom mode“.Just hold the spacebar and it will get you to BootRom prompt.Then give the commands as follows

BootRom>config none
BootRom>boot

Then we can see the booting process and it will reach at a point where username and password is asked.Enter username as “admin” and there is no password set for this account by default.So don’t provide any password and just hit enter.

After logging in successfully the prompt will ask you for enabling/disabling telnet,snmp,failsafe account etc.Configure your required options accordingly.After setting up all these it will take you to the basic command line.There we can set the password for the accounts.By default there are two accounts available in an extreme switch.One is “admin” which is the privileged account and other account is the “user” with only basic options.Following is the command to set password for admin account.

For admin account :

x150-48t# configure account "admin"
Password
Repeat Password

For user account :

x150-48t# configure account "user"
Password
Repeat Password

Set the passwords and save the entire configurations as follows

x150-48t# save

And you are done……
