Automatic Password Rotation for Raritan PDU

I am trying to implement the automatic password rotation for a Raritan PDU but this is failing with errors, presumably with the SSH command sequence.

First question, is there a way to view the logs to debug this? We have various other custom devices to set up so it'd be helpful to be self sufficient with these.

For information, the command sequence to change the password via SSH is:

Welcome to PX2 CLI!
Last login: 2024-04-25 02:53:21 GMT [Web GUI from 10.224.5.123]

# config
config:# password
Current password: <the old password>
Enter new password: <the new password>
Re-type new password: <the new password>
config:#

Help appreciated!
