Echelon i.LON 100 e2 Internet Server - Manual (Page 95)

i.LON 100 Internet Server User’s Guide B-3
The i.LON 100 gets a duplicate IP address assigned from a DHCP server,
and either boots using its default IP address (i.e. 192.168.1.222), or boots
using the duplicate IP address.
• If the i.LON 100 device boots using its default IP address when it has
obtained an address via DHCP, it is probably because the DHCP server
assigned an address already in use by another machine on the network. This
may happen if the other machine is disconnected from the network long
enough for its DHCP lease to expire, yet continues using that address after
reconnecting to the network. Make sure all other machines on the network
using DHCP have valid leases. If the i.LON 100 detects this condition, it will
boot using its default IP address (typically 192.168.1.222), and will continue
attempting to contact a DHCP server. Once it can contact a DHCP server, the
i.LON 100 will reboot to obtain a new IP address.
• The i.LON 100 may not initially detect the above condition, in which case it
will boot using the duplicate IP address. At some point the i.LON 100 may
discover that the address is a duplicate, but will continue using it. Make sure
all machines on the network using DHCP have valid leases. Reboot the i.LON
to obtain another address, if necessary, or use a statically configured address.
The i.LON 100 exhibits problems due to a low-memory condition. This
could be indicated by one or more of the following: “out-of-memory”
messages, slow network access, application performance problems, or
even an unexpected reboot.
• Reduce the number of Alarm Notifiers and/or the size limit of the alarm
Summary Logs (which are kept in RAM).
• Reduce the number of Web clients that are simultaneously accessing the
i.LON 100.
• If you are making calls to the SOAP interface on the i.LON 100, refer to the
i.LON 100 Programmer’s Guide for specific recommendations on limiting
SOAP messages.
