Primary Units Manage Link Units; Releasing A Link Unit - LEGRAND Server Technology PRO3X User Manual

Primary Units Manage Link Units

The primary unit manages the following functions for the entire chain of linked units:
• •
User management and authentication – configured only on the primary.
• • Date and time – the primary synchronizes its date and time settings to link units. If NTP is not used,
then the synchronization interval is every 10 minutes.
• •
Device settings – only the primary device settings are configurable, except for Network Settings.
Some settings will be synced to link units. The serial port is configurable for the primary only; link
units use the console.
• •
Data model settings – such as outlet names, thresholds, peripherals, etc., are configured on the
primary and stored on link units. Features vary by model.
• •
Lua scripts – Communication with link units in a Lua script is possible.

Releasing a Link Unit

Releasing a link unit means the unit is separated from the chain and the unit then becomes standalone.
The primary unit no longer has access to the released link unit.
