5.2 Setting the default IP Address
To reset the CPU LAN ports to their default IP addresses, press and hold the ENG and
FULL RESET buttons on the CPU front card until the card resets.
Note:
Do not release the ENG and FULL RESET buttons until the CPU card LED panel shows
either an A or a B
.
The LAN1 Ethernet port is reset to the factory default address of 169.254.0.100 and the
second Ethernet port to the 0.0.0.0 (blank) address.
The LAN1 reverts to a link local address of
169.254.0.100 only after trying and failing to
acquire an IP address from the network at startup.
The LAN1 defaults to the DHCP mode of operation. This mode of operation is not to be
used once the frame is operational as it delays the start-up of the frame following any reset.
5.3 Using the CPU card Ethernet ports
The CPU card Ethernet ports are normally connected to a LAN and used to communicate
with clients such as EHX and Production Maestro. The Ethernet port functionality depends
on the IP address setup.
If an IP address of 0.0.0.0 is configured on the second Ethernet port, it will not be used
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.
