ETHERNET SWITCH FAIL
ETHERNET MODULE
OFFLINE
No response has been
received from the Ethernet
module after five successive
polling attempts.
• Loss of switch power.
• IP/gateway/subnet.
• Incompatibility between the CPU and
the switch module.
• UR port (port 7) configured incorrectly
or blocked
• Switch IP address assigned to another
device in the same network.

PORT 6 OFFLINE
An active Ethernet port has
returned a FAILED status.
• Ethernet connection broken.
• An inactive port’s events have been
enabled.
No setting required; the N60
will read the state of a general
purpose input/output port on
the main CPU upon power-up
and create the error if there is a
conflict between the input/
output state and the order
code.
EQUIPMENT
MISMATCH: Card XXX
Missing
The N60 has not detected the
presence of the Ethernet
switch via the bus board.
The N60 failed to see the switch module
on power-up, because switch won’t
power up or is still powering up. To clear
the fault, cycle power to the N60.
