Extended Cascading with PX3-iX7 Models
Only PX3-iX7 PDUs support cascading via either Ethernet or USB ports.
These PDUs support cascading via Ethernet ports because they have two
Ethernet ports. Other Raritan products do NOT support Ethernet
cascading.
There is no restriction of using which Ethernet port of PX3-iX7 for
network connection and which port for cascading, but the 'green' ETH1
port (ETH 10/100/1000) is highly recommended for network connection
because it supports up to 1000 Mbps.
An Ethernet-cascaded device must have its Ethernet interface enabled
for the networking to work properly. By default the Ethernet interface is
enabled.
The distance between two Ethernet-cascaded PDUs can be up to 100
meters, but the distance between two USB-cascaded PDUs supports up
to 5 meters only.
Decide the cascading mode first before establishing the chain. All
cascading modes support a maximum of 16 devices in a chain.
When establishing a cascading chain in the port forwarding mode, make
sure you follow the guidelines described in the section titled
Unsupported Cascading Connections for Port Forwarding
(on page
45).
Special application: You can "loop" a cascading chain to create
network communication redundancy (bridging mode only), but only
when your network supports R/STP protocol. Make sure that your
network has R/STP enabled if using a cascade loop (bridging mode)
or else network loops may occur.
