Appendix K: Additional PX3 Information

Tip: To determine which PX3 may be the failure point of network, you
may ping each PX3 in the cascading chain, or check the slave-related
events in the event log of each PX3. See
The Ping Tool
(on page 810) and
Slave Device Events in the Log (on page 809).
For an iX7
™
cascading chain, also check the following:

Whether the Ethernet interface (ETH1 or ETH2) where the network or
cascading cable is connected is disabled on the cascaded device in
question or any upstream device.

Whether the connection complies with the cascading guidelines if it
is set to the Port Forwarding mode. See
Unsupported Cascading
Connections for Port Forwarding (on page 45).
Slave Device Events in the Log
The log messages for connection/disconnection of a cascaded device are
different for USB-cascading and Ethernet-cascading chains.
Messages for the Ethernet-cascading chain:
Whenever the connection or disconnection of a master/slave device is
detected, both PX3 devices connected via that network cable record this
event in their internal logs.
There are two slave-related events:
Event Description
The ETH1/2 network
interface link is now up. This log entry is generated when an iX7
™
detects the connection of the upstream
or downstream cascaded device on one
of its Ethernet ports.
