The web interface on a Raritan Dominion PX device was not accessible. In order to fix the issue via the clp (cli) we plugged a console cable in with the following settings

Data Rate: 9600
Parity: None
Data Bits: 8
Stop BIts: 1
Flow Control: off

 

When connected select : clp 

You will then be prompted for the admin username and password.

To restart the management interface type

clp:/> reset /system1

 

This does not affect the power outlets.
