PART IV - PROBLEM SOLVING
How to perform a “Software reset”? And why?
When Interface-settings are changed the CPU has to be started. In the web interface a pop up will appear when needed:
Remotely
Software reset can be done via the web interface. It is important to understand that a software reset has no impact on
power distribution of the PDU. So a reset can be performedat any time without having to interrupt the power supply and
without losing the settings in the PDU.
Locally
The software can be reset using a paperclip or some other kind of thin and rigid rod to press the reset button. This button
is mounted behind the hole labelled as ‘rst’ on the PDU which is next to the Ethernet connection port.
How to perform a “Factory reset”?
If the PDU can no longer be accessed via the LAN, for example, because settings have been changed, restoring IP access
may be needed. The following procedure causes the PDU to adopt various default values, which allows it to be detected on
the network again without losing any of the other settings in the PDU. However, the power supply must be interrupted in
order to perform this restore procedure! The procedure is described in five steps:
1. Interrupt the power supply to the PDU.
2. Restore the power supply.
3. Wait for one second and afterwards press the reset button using a paper clip.
4. Wait for a further second and press the reset button again.
5. Wait for a further second and press the reset button again.
The PDU has now adopted the default values for the IP settings. The access control fields and the web server settings have
also been returned to the standard values.
Please note that because the power is removed, outlets will also be out of power. Hence, during this process there won’t
be any measuring.
Please keep in mind that kWh totals will NOT be reset during this process.
