Cascading All Devices via USB
You must set the cascading mode before establishing the chain. See
Setting the Cascading Mode
(on
page 150).
Any certified USB 2.0 cable up to 5 meters (16 feet) long can be used.
Both cascading modes support a maximum of 16 devices in a chain.
The following diagram illustrates Legrand PDUs cascaded via USB.

To cascade Legrand PDUs via USB:
1. Make sure all of Legrand PDUs are running firmware version 3.4.11 or later.
2. Choose the appropriate one as the master device.
When the Port Forwarding mode over "wireless LAN" is intended, the master device must be a
Raritan product with two USB-A ports, such as PX3, EMX2-888, PX3TS or BCM2.
3. Log in to all devices one by one and select the same cascading mode.
