4. CONNECT THE SURFACE TO THE IMPULSE CORES
Surface Ethernet Switches
The surface Ethernet switches are the
interfaces between the control surface via
the section processors and the Impulse
processing cores. To provide redundancy,
two surface Ethernet switches are fitted,
primary and secondary. The system will
always attempt to boot and run on the
primary, however if there is a problem
with the primary or its connections, the
secondary will automatically take over.
Like the section processors, the primary
and secondary surface Ethernet switches
are housed in a ventilated enclosure
under the upper surface at the rear of
the console in any two of the console
sections. In the image below they are
shown in section 1 and section 3, when
viewed from the rear, the primary surface
Ethernet switch is usually placed in the
left hand section.
The communication with all the control
panels and displays is via each section
processor. Each section processor is
connected to the primary and secondary
surface Ethernet switches using the
ARGO SURFACE SECTION CONNECTIONS TO IMPULSE CORES VIA BUILT IN ETHERNET SWITCHES
primary and secondary GB Ethernet ports
on each section processor.
The primary surface Ethernet switch
typically has 10 ports and each of
the sections connect to a port. In
the example below ports 1-3 are
connected leaving ports 4-8 available for
connections to sections 4-8 depending
on the size of the surface. Port 9 is
used as the IP link from the primary
surface Ethernet switch to the primary
Impulse core on SFP Port 3 of the
control processor module. See the
connections in the image below.
This is repeated using the section
processor's secondary ports to the
secondary surface Ethernet switch and
on to the secondary Impulse Core on SFP
Port 3 of the control processor module.
See the
red
connections in the image
below.
Note: the 2 Impulse cores are directly
connected between both control
processor modules on SFP port 5's, for
IP network redundancy. See the
connection in the image below.
Note: if there is a requirement to add
other console sections to this surface
in the form of a Sidecar where say a
separate console on wheels is brought
into the studio, then the connections
from the Ethernet switches in the sidecar
or if no switches the connections directly
from the section processors can be
added to the Primary and Secondary
Ethernet switches rather than routing
the cables back to the Impulse cores
separately. The sidecar may not even be
in the same room as due to the nature of
blue
the IP Network the physical location of
the surfaces are not a factor.
The routing of the core connections to
their applications is made using the
Configure application see
"3. Configure the Surface IP
Connections" on page 10
Note: the rest of the internal console
connections are exactly the same as
defined in the Argo Installation Manual
and are generally pre-configured as per
the works order.
