The following illustrations show the ID
switch on the modular I/O controller card
from the side and top views.
Modular I/O card slots
Please note that changing the card type
fitted in a modular I/O box slot requires a
change to the network configuration.
If the order that cards are fitted in a
modular frame matters, please discuss
this with your Calrec project engineer
prior to delivery. If for any reason the card
order needs to be changed post delivery,
please contact our Customer Support
team or your local distributor for guidance.
Cards of the same type can be
interchanged with no configuration
change being required.
Additional cards can be fitted in previously
empty slots without further configuration.
Argo AoIP Modules connections
The Argo AoIP I/O modules are not
fitted with controller switches instead the
modules' addresses are determined using
the
Connect
application. The connection
requirements are however the same as
other AoIP devices and the various Argo
AoIP modules all have AoIP A & AoIP B
connections and are connected on the
media network to the Impulse routers via
AoIP switches.
The AoIP A RJ45 port connects to an
RJ45 port on the Primary Router via
an AoIP switch and the AoIP B RJ45
port connects to an RJ45 port on the
secondary router typically via another
AoIP switch as shown below.
Impulse Router connections
I/O boxes require a connection to a front
panel port on to an Impulse router module.
Each I/O box has two AoIP ports to
provide redundancy. AoIP 1 should
connect to a 'A' router ports & AoIP 2
should connect to the 'B' router ports.
Like the AoIP ports on the router
modules, connections on AoIP I/O
devices are SFPs and therefore the
connection type required (copper / single
mode fibre / multimode fibre) needs to be
specified at the time of order.
Note, any fixed RJ45's ports( if any,
i.e. not SFP ports) on the rear of fixed
format AoIP/Hydra2 I/O devices are
not functional, if copper connections
are required, copper SFPs should be
specified
.

Please refer to the '
AoIP I/O manual
(926-293).pdf
' for more comprehensive
details on AoIP options and connectivity.
Router Redundancy
Calrec AoIP products support network
redundancy, meaning that each device
has a pair of A and B AoIP network
connections.
It is not essential to have both connected,
however it is recommended in order to
provide resilience for network traffic.
Both A and B connections can be
passed over the same physical switching
hardware, but to provide the best
redundancy, it is recommended that A and
B connections are passed over physically
separate networks.
With AoIP redundancy based on
ST2022-7, there is no real “primary”
and “secondary” - devices are free to
receive audio from either A or B networks
seamlessly on a packet by packet basis.
Impulse Core redundancy has a complete
failover system, only one core of a
redundant pair is truly active at a given
time. The image at the bottom of the next
page shows a single impulse core.
For complete redundancy, both primary
and secondary cores should each connect
to both A and B audio networks.
For further information about Redundancy
connectivity using Primary and Secondary
Impulse Cores please refer to the
'
Impulse Installation Manual (926-
288)'.
