To change Mellanox switch passwords, open a secure shell (SSH) session to the switch's management CLI using the admin user and use the username command.
To change the admin password:
1. Obtain the switch IP. You can find this in the VAST Web UI on the Switch tab of the Infrastructure page, or in the output of the switch list VAST CLI command.
2. Run the following commands, where <Switch_IP> is the switch IP and <New_Password> is the new password that you want to set:
```
> ssh admin@<Switch_IP>
switch> enable
switch # config terminal
switch (config) # username admin password <New_Password>
switch (config) # conf write
switch (config) # conf write
```
