Linking Units

The Linking feature allows the linking configuration of a single Primary unit to multiple link units so that
you can view and manage them all in one place. The primary unit has full knowledge of the location of
the connected link units, as well as the power and/or environmental information of all link units. The
primary unit provides visibility and control both the primary unit and the link units from within the GUI,
SNMP, and CLI.
Communication between primary and link units happen via HTTPS. When establishing the connection
the link unit to be added must have HTTPS enabled at the default port 443. For added security,
certificates are checked. Link units must have the demo certificate, or if custom certificates are set, the
CA certificate must be installed onto the primary unit. (Go to PDU > Link Units page > "TLS Certificate"
button.)
All network modes are supported. Network and physical configurations must be completed before
configuring Linking.
The administrator privilege is required for all management actions (adding, configuring, releasing) of the
Linking feature. Each unit in the chain can be monitored and managed from anywhere by the network
protocols HTTP(S), SNMP, SSH, and Telnet.
All units in the linked chain must be the same model. All units must run the same firmware version,
which can be upgraded respectively for each unit in the chain.

What's the difference between a "primary unit" and a "link unit"?
Primary and link units are the same model PRO3X that are equal to each other, and each has its own IP
address. You designate a PRO3X as the primary unit by logging into it and then adding a link unit. The
first unit becomes the primary, and when the first link unit is added, the primary unit is automatically
assigned ID "1", which is reserved to identify a primary unit only, and the ID "1" cannot be edited. A
connection between the primary and the link unit has now occurred and the chain is formed.
As you continue to add link units to the chain as desired (up to seven link units), you select Link ID "2"
through "8" for the Link ID numbers. Note that the Link ID "2-8" is the sequential number of each link
unit that you select as you add the unit to the chain, and once selected, the Link ID cannot be edited.
