The ID of the primary unit is automatically assigned the ID "1", as shown in the example as "My PDU
(1)". The ID cannot be edited.

Options for Adding Link Units

To start configuring the Primary Unit with Link Units, your options in the web interface depend on the
network and physical configuration of units.
• •
If you configured units in Independent or Bridging Mode, where they may or may not be physically
cascaded, and each one is assigned its own IP address, you can manually add each link unit. You can
use this manual function anytime to add link units. See
• •
If you configured units in a Port-Forwarding Cascade Mode configuration, in which they are
physically cascaded and only the first unit is connected to the network, you can automatically link
the cascaded units. See

TLS Certificates for PDU Linking

To enhance security, you can upload a TLS certificate to your primary unit to be verified for
communication with the link units. The built-in demo CA certificate is used to verify link units until you
upload your own. You will need a CA certificate for the primary unit, and certificates for each link unit
that have been signed by the same CA. Before creating the cascade, CA-signed TLS certificates must be
installed to designated link units. See
If you are using the Link Port for setup at the rack, or if you are in Port Forwarding mode, certificates for
link-local addresses and/or internal wildcard domain (*.pf-cascade) are required. Note that Link Port is
not available on all models.
▶
To add the CA Certificate to the Primary Unit:
1) Login to the designated primary unit.
2) On the PDU page, click TLS Certificates.
3) Click Browse, then select the CA certificate file and click OK to upload it.
4) Select the "Allow Expired and Not Yet Valid certificates" checkbox to skip time verification when
certificates are validated.
5) Click Save.

Adding a Link Unit

A link unit (up to seven units) can be added to a single primary unit.
On the PDU page, the Link Units section will contain all link units. The Add Link Unit button, highlighted
in green in the screen example, also displays in the Link Units section.
