Chapter 5: PDU Linking
77
Note: Re-linking uses the same Link Unit ID and hostname, but you will need to
reauthenticate with your login credentials.
What user privileges are required for managing the PDU Linking
configuration?
Administrative privileges are required for both the master unit and link unit. To
add a link, your administrative login account is required, but after that you only
log in to the master to manage the chain, as all link units in the chain are visible
in the user interface from the master unit view.
What happens if the connection is lost between the master and link
units?
If the network connection is lost, these link unit functions will still work:
1. energy accumulation
2. local display (regular metering values and alerts of raised thresholds)
3. maintained outlet states
and these link unit functions will stop working:
1. event log entries are lost
2. event engine rules/alarms
3. remote access to the link unit
4. synchronization of master settings and time when not using NTP
Which system areas of the master and link units are automatically
synchronized?
The master PDU periodically checks link unit reachability. You can define rules
to be alerted when communication with a link unit fails, such as a system alarm.
Some link unit settings are automatically synchronized with the master:
1. Peripheral device settings
2. Front panel privileges and default view
3. USB host port lockdown
4. Time and date settings
5. General data logging settings
