CHAPTER 5 – TROUBLESHOOTING CONFIGURATION PROBLEMS
The X501NET is a simple device to configure. Most configuration problems are caused by errors in
network configuration.
5.1 Conflicts With DHCP Server
If there is a DHCP server attached to the same LAN as X501NETs, it is necessary to configure the
DHCP server to exclude the TCP/IP addressed used by the X501NETs for the addresses that it
managed. FAILURE TO DO THIS CAN RESULT IN DUPLICATE ADDRESS ASSIGNMENT
AND CAUSE THE SER TO STOP WORKING CORRECTLY!
5.2 Network Address Conflicts
The X501NET is comes factory configured with address 192.168.1.234. This is the same address
that is usually used for MUX1. To add a new X501NET to an existing SER, it is necessary to
configure the TCP/IP address before attaching the X501NET to the LAN that is part of the SER. This
can be accomplish by having a user workstation or laptop computer attached to a hub that is not part of
the SER LAN and connect the X501NET to this mini-LAN for configuration before attaching it to the
LAN that is part of the SER.
5.3 Network Traffic Issues
Normally the X501NETs are on a LAN dedicated to the SER. Network traffic is virtually never an
issue in this case. Sometimes it is necessary to share this LAN with other network devices. If there is a
great deal of traffic from these devices (video, large file transfers, etc.) it can impact the performance
of the SER system. If this is the case, the LAN should be split into multiple LANs with filtering
bridges or routers between the LANs and the devices that are the source and destination of high traffic
transfers put onto a different LAN.
5.4 Lost Password
DO NOT LOSE THE ADMINISTRATOR PASSWORD! If the administrator password(s) is lost,
the X501NET controller boards must be returned to Ronan to be re-programmed to factory defaults.
