page 548).
Cascading Multiple PX3 Devices for Sharing Ethernet Connectivity
You can have multiple PX3 devices share one Ethernet connection by
cascading them via one of the interfaces below:

USB interface -- for cascading multiple PX3 or multiple iX7
™
PDUs

Ethernet interface -- for cascading multiple iX7
™
PDUs
Warning: Firmware version 3.3.10 is NOT compatible with old
firmware versions in terms of the USB-cascading feature so all
devices in a chain must be running version 3.3.10 or later. Otherwise,
a networking issue occurs. When upgrading an existing
USB-cascading chain from any version prior to 3.3.10, the upgrade
must start from the last slave device, then the second to last, the
third to last, and so on until the master device. Any upgrade without
following this sequence results in the networking failure of some
cascaded devices.
