MASTER ROUTERS
A Master Router needs to be present
on any Hydra2 network. In a single
core system, there is only one active
router card. All of the router cards
fitted within such a core will be
factory pre-configured as Master
Routers so that whichever card is
active will be the master.
In a multi-core system, one of the cores
needs to be dedicated as the Master
Router and the router cards in this core
should be configured as such. All other
routers on the same network need to be
configured as Slaves.
Having more than one Master Router
core on a Hydra2 network will result in
instability.
Not having an active Master Router on a
network will also cause instability.
The core configured to be the Master
Router needs to remain powered and
active to maintain reliability of the network.
No individual system should be used if the
Master Router is not active.
Similarly, it is important to understand
the network topology to know which I/O
boxes are available to which consoles if
individual cores (other than the Master)
are powered down.
When two or more networks are joined or
a network is split, for example if two OB /
mobile units are occasionally connected
together, it is essential that the Master
Routers are managed. If connecting
two networks, one of the masters will
need to be reconfigured as a slave.
When separating two networks, one of
the slaves needs to be changed to be a
master.
ConfiguringMaster&SlaveRouters
Only the active main router card in the
dedicated core needs to be configured as
the Master, however, it is good practise to
set the secondary main router and also
the primary and secondary expansion
routers as masters as well. This allows for
cards to be moved around within the same
rack to aid troubleshooting if hardware
problems are experienced as well as
ensuring the backup is correct in the event
of a hot-swap.
Changing the Master/Slave status of a
router affects the whole Hydra2 network
and as such, should only be carried out by
engineers with a good understanding of
the network topology.
Please contact our customer support
team - support@calrec.com, or your
regional Calrec distributor for guidance on
changing router master/slave statuses.
AutoPromote
A Hydra2 network needs one master
router to function correctly. If anything
causes the master router to go off-line,
another router on the network must be
promoted to be the master to keep the
system running—from Apollo/Artemis
software V1.16, Auto Promote allows this
to happen automatically.
To avoid losing valuable data the Hydra
database is copied from the master router
to any routers in the network which may
auto promote themselves. The Hydra
database stores the following information:
• Details of I/O connected on network
• Patches made via H2O
• Patches made via SW-P-08
• Port labels
A system of levels and time delays is used
to control which routers can take over
the master router status and in which
order. Auto Promote is setup by Calrec
engineers and so should be planned with
your Calrec project engineer during the
ordering process.
