accessible or responding. Click [
Discover
] again and
wait until the discovery process to complete. Close the
current WinDiscovery session and restart the
WinDiscovery application. Take steps to increase the
bandwidth and reduce network traffic.
If these continue to be ongoing problems, consider the
Telnet
configuration method or remove the device to
an isolated LAN.
MDN PERIODICALLY RESETS ITSELF
MDN name appears in red text under WinDiscovery
device tree
MDN is being assigned an IP address of 169.254.xxx.xxx
MDN is showing an “Error” field under the status
window in WinDiscovery
Possible reasons and solutions:
1. Incorrect network configuration may be causing the
device to receive a fallback IP address and or perform
soft restarts. Verify that the IP address configured for
the device is correct. If you manually enter (or DHCP
assigns) an IP address that already exists on the
network, this will create an IP address conflict. The
device will reset its address (fallback) to one within the
link-local address space. Determine the cause of
fallback IP address and resolve issue. View the error
status field under the status window to help determine
the cause of why the device received a
“169.254.xxx.xxx”. Near the bottom of the status
window the error will be displayed. (If there is no error
the text box will not be displayed.)
2. If static IP addressing is being used the original
conflicting static IP address can be restored. Perform a
soft restart of the network device using either
WinDiscovery or Telnet prior to changing any other
configuration parameters.
3. If DHCP was selected and the network device falls back
to a “169.254.xxx.xxx” address approximately every 10
minutes (depending upon the “Advanced Settings”
values) the Ethernet interface will be reinitialized and
the network device will attempt to get an IP address
from the DHCP server. If the network device is
successful, the error will be cleared and the new
address from the DHCP server will be used. If a
discovery was done using WinDiscovery or Telnet was
used this initialization will be delayed by two hours.
STATUS LED IS FLASHING
Status in WinDiscovery says ‘”
Unsynchronized
”
MDN is unable to find NTP reference, either primary or
secondary
If the configuration of the network
device is changed while a
“169.254.xxx.xxx” is being used (for
example: changing the Time Zone
offset), then the current
“169.254.xxx.xxx” address will become
the permanent static address and the
original conflicting static address is lost.
At this point, it is necessary to manually
change the static IP address to one that
does not conflict, or you may do a “Reset
Configuration” to restore the system to
factory default settings.
