Each core is fitted with a primary/
normally active router card in slot
2, and a secondary/backup router
card in slot 7. In an 8U core, optional
expansion router cards can be fitted—
primary in slot 1, secondary in slot 8.
Hydra2Connectivity
All I/O boxes have a primary/normally
active port 1, and a secondary/backup
port 2.
Port 1 of each I/O box should connect to
one of the front panel primary router or
primary expansion router ports.
To provide redundancy, port 2 of each I/O
box should be connected to secondary
router / expansion cards in the same core
as the primary connection.
Redundancy is provided when connecting
cores together by fitting a normally active
link between the primary router in one
core to the primary router in the other
core, and a backup connection fitted
between the secondary router of one
core to the secondary router of the other.
Core-to-core connections should always
be made to the main primary / secondary
routers, not expansion cards.
All Hydra2 connections—on I/O boxes
and on router cards—are made via SFPs
(small format pluggable) modules. Please
refer to “SFP - Overview” on page 30
for information on connection types, pin-
outs and length limitations.
CoreRedundancy
Standard cores provide complete
redundancy by being fitted with a full
set of backup hardware—a secondary
router, Control Processor and PSU, as
well as expansion router and DSP card if
primaries of these are fitted.
Sophisticated hardware and software
status monitoring, along with highly
flexible comms and data routing allow
for secondary cards to quickly and
automatically take over from primaries if
problems are detected. During a hot-
swap situation, the minimum amount
of hardware required swaps over to the
secondary cards in order to minimize
disruption and to retain maximum
redundancy in the unlikely event of a
further failure.
