Linking Cascaded Units - LEGRAND Server Technology PRO3X User Manual

About the Link ID
The Link ID "1" is automated and reserved internally for the primary unit. The primary unit's ID "1"
cannot be edited.
The Link ID "2-8" is available for you to select as the ID for each of the link units you add to the chain.
From the Link ID drop-down, you can select the desired Link ID to manage the link units in the chain.
Once selected, the Link ID cannot be edited.

Linking Cascaded Units

When units have been configured in a physically-connected cascade in Port Forwarding mode, PRO3X
can detect expansion units via the primary unit, and link these cascaded units.
While a cascaded chain supports up to 32 units, and may include different products and different
models, Linking can only accommodate a maximum of 8 units linked, and all units must the same
models running the same firmware version.
Link units can be added by different methods, so remember that 8 total is the maximum overall.
You can link cascaded units in two ways:
• • Link All Cascaded Units (Automatic method): Use this method when your cascade's 1 through 8
expansion units are same product/model/firmware, and you want that configuration simply and
directly converted to Linking.
The automatic option will attempt to link all cascaded units, assigning each either a link-
local IPv6 address or node-index-dependent URL as it is discovered and linked. The process
begins with the first expansion unit connected to the primary, and proceeds through the
cascade in order. The process ends when all 8 Link unit IDs have been filled, or when a link
attempt fails.
• •
Custom: Use this method when you want to selectively add only some expansion units from the
cascade, or otherwise customize how expansion units are linked, and in what order.
