▶
What user privileges are required for managing the Linking configuration?
Administrative privileges are required for both the primary unit and link unit. To add a link, your
administrative login account is required, but after that you only log in to the primary to manage the
chain, as all link units in the chain are visible in the user interface from the primary unit view.
▶
What happens if the connection is lost between the primary and link units?
The primary unit's dashboard displays information about unreachable link units in the Link Unit Failures
section.
If the network connection is lost, these link unit functions will still work:
1) Front panel display
2) Energy accumulation and outlet states (not applicable to SRC)
and these link unit functions will stop working:
1) Event log entries are lost
2) Event rules, actions and alarms
3) Remote access to the link unit
4) Synchronization of primary settings and time when not using NTP
▶
Which system areas of the primary and link units are automatically synchronized?
The primary unit 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 primary:
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
▶
How are firmware updates handled?
Uploaded firmware images in the GUI are automatically distributed to all link units at the same time.
Starting a firmware update requires the automatic image upload on the link units to be finished first.
