If an IP address of
for Tx or Rx. This is the default setup if the default IP address is set as described above.
All matrix to matrix traffic is sent out on both Ethernet ports. This applies to both directed and
broadcast packets. All matrix to matrix traffic is also received on both Ethernet ports. If the
traffic is transaction related, the second (duplicate) message received is not consumed, but
simply dropped.
The matrices listen for client connections on both Ethernet ports. Once the connection is
made it is added to the list of connections to service. Broadcast type Tx data is duplicated
out on each connection (for example, HCI connection to the matrix from 3rd party
applications).
The EHX Server makes a connection on either the main or backup Ethernet port of each
system in the linked set. If both are up, this will default to the primary port. In the event that
connection is lost to the currently active port on a matrix the EHX server will swap over to
using the other Ethernet port. If this connection is lost only on one matrix in a linked set, the
others will not be affected.

Configuration restrictions for Ethernet ports
The network ID on the first Ethernet port must be different to that of the second port.
The network ID is defined by the IP address and the network mask for the port. For example
a network address of
. Therefore in this scheme the second port could not have an IP address, starting
172.16
with
172.16.
If the network mask is extended to
so the second port could have an address of
255.255.255.0
If both Ethernet ports are set up with the same network ID this condition results in data loss
on one or both of the Ethernet ports.
Note:
Ethernet redundancy and the use of a default gateway is not supported. An IP address and
gateway combination on an Ethernet port means that all Tx traffic to any address is possible
on the port. Traffic that actually matches the other Ethernet port can therefore be sent out on
the wrong port.

CPU card fail-safes
The CPU card's non-volatile memory stores all information about the current operating
configuration and the three additional configurations, allowing the system to restore itself
automatically after:
• A power failure.
• The replacement of a port card.
• The replacement of a panel.
An Eclipse HX-Median system operates with either one or two CPU cards.
