36 Legrand PDU User Guide
Extended Cascading with Legrand PDUs
You can use either Ethernet port on the Legrand PDU PDU for cascading.
You must set the cascading mode before establishing the chain. See
Setting the Cascading Mode
(on
page 165).
Both cascading modes support a maximum of 16 devices in a chain.
When establishing a Port-Forwarding chain, make sure you follow the guidelines described in the section
titled
Restrictions of Port-Forwarding Connections
(on page 38).
You can mix Ethernet and USB cascading in the Legrand PDU PDU chain if preferred. The following diagram
illustrates such a chain.
The distance between two Ethernet-cascaded devices can be up to 100 meters, while the distance between
two USB-cascaded devices supports up to 5 meters only.
