resets. This will reset the LAN1 ethernet port to the factory default
address of 169.254.0.100 and all other ethernet ports to the 0.0.0.0
(blank) address and enable DHCP. If the system is fitted with two CPU
cards (master and slave) ensure that the default IP address procedure
is carried out on both cards but with only the card being reset plugged
in as detailed below.
• Remove the slave CPU card if present.
• Press and hold the ‘ENG’ and ‘FULL RESET’ front panel buttons
simultaneously then press the ‘RESET’ button on the master CPU
card.
• Replace the slave CPU card if there is one otherwise the
procedure is complete.
• Remove the master CPU card.
• Press and hold the ‘ENG’ and ‘FULL RESET’ front panel buttons
simultaneously then press the ‘RESET’ button on the slave CPU
card.
• Replace the master CPU card.
ETHERNET OPERATION
The CPU card ethernet ports are normally connected to a LAN and
used to communicate with clients such as ECS 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 e.g. HCI
connection to the matrix from 3rd party applications.
The ECS 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 ECS 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.
