After Sales Modifications
Please be aware that any modifications
other than those made or approved by
Calrec Audio Limited or their agents, may
invalidate the console’s warranty. This
includes changes to cabling provided by
Calrec and variations to the recommended
installation as detailed in Calrec
documentation.
Modifications to this equipment by any
party other than Calrec Audio Limited
may invalidate EMC and safety features
designed into the equipment. Calrec
Audio Limited can not be liable for any
legal proceedings or problems that may
arise relating to such modifications.
If in doubt, please contact Calrec Audio
Limited for guidance prior to commencing
any modification work.
Installation
In many installations the AC power
connectors will not be readily accessible,
effectively making the equipment
permanently connected. The installation
should be carried out in accordance with all
applicable installation rules and regulations.
Service Personnel
The AC power disconnect devices are
the 2 x IEC (IEC60320-1 C13/C14)
couplers located at the rear of each unit.
WARNING: The apparatus has a dual
power system. It is essential that BOTH
AC power IEC couplers are disconnected
to prevent exposure to hazardous voltage
within the unit.
Third Party Equipment
Integrating third party equipment into
a Calrec system may compromise the
product’s ability to comply with the
radiated emission limits set in the EMC
(Electro Magnetic Compatibility) standard
EN55022.
Calrec Audio Limited can not be
responsible for any non-conformities
due to use of third party equipment. If
in doubt, please contact Calrec Audio
Limited for guidance prior to integrating
any third party equipment.
ESD (Static) Handling Procedures
In its completed form, this equipment has
been designed to have a high level of
immunity to static discharges. However,
when handling individual boards and
modules, many highly static sensitive
parts are exposed. In order to protect
these devices from damage and to protect
your warranty, please observe static
handling procedures, for example, use an
appropriately grounded anti-static wrist
band. Calrec will supply an electrostatic
cord and wrist strap with all of its digital
products.
All modules and cards should be returned
to Calrec Audio Limited in anti-static
wrapping. Calrec Audio Limited can
supply anti-static wrapping upon request.
This applies particularly to digital products
due to the types of devices and very
small geometries used in their fabrication,
analogue parts can, however, still be
affected.
RoHS Legislation
In order to comply with European RoHS
(Reduction of Hazardous Substances)
legislation, Calrec PCB and cable
assemblies are produced with lead-free
(tin/copper/silver) solder instead of tin/
lead solder.
In the unlikely event of a customer
having to carry out any re-soldering on
Apollo, Artemis or Hydra2 hardware,
it is imperative that lead-free solder is
used; contaminating lead-free solder with
UKAS AND RAB REGISTRATION
LEAD FREE STICKER
LEAD FREE
leaded solder is likely to have an adverse
effect on the long-term reliability of the
product. Circuit boards assembled with
lead-free solder can be identified (in
accordance with IPC/JEDEC standards)
by a small oval logo (see below) on the
top-side of the circuit board near the PCB
reference number (8xx-xxx). The same
logo is used on the connector hoods of
soldered cable assemblies.
If in doubt, please check with a Calrec
customer support engineer before
carrying out any form of re-soldering

CONNECTING THE SURFACE TO THE CORE
The Summa surface requires fibre
connections to the core via singlemode
or multimode LC SFPs. For a
redundant system two connections
are required, primary and secondary.
In the diagram on the next page the
primary connection is the solid line
and the secondary connection is the
dashed line. If you are running a
non-redundant Summa 128, only the
primary connection is required and the
cards on the right of the core will be
replaced by blanking plates.
Calrec do not provide interconnecting
fibres/cables, as the length, type and
quality will vary for each installation.
SFPs can be supplied with your Summa
system if specified at the time of order.

The left hand SFP, when viewed from
the back of the surface, is the primary
connection and on the right is the
secondary connection.
In the processing core, the left hand
Control Processor is the primary, the right
hand is the secondary.
A fibre connection should be fitted
between the primary surface connection
and the primary Control Processor’s
‘Surface 1’ connector. Unless a non-
redundant system has been chosen,
a backup connection should be fitted
between the secondary surface
connection and the secondary Control
Processor’s ‘Surface 1’ connector for
redundancy.
Note, the ‘surface 1’ connection is labelled
‘MAC 7’ on some control processor
models.
It is important to ensure that these
connections are made correctly - primary
to primary, secondary to secondary and
using the correct fibre SFPs.

SUMMA CONSOLE TO CORE CONNECTIONS – 2

14 SUMMA Networked Audio Production System Getting Started
HYDRA IDs
Hydra2 I/O boxes with valid Hydra
IDs (HIDs), are automatically detected
and added to the Hydra database
when first plugged in to the network.
This database entry will remain until
it is manually deleted via the network
management organiser, H2O.
It is important that careful consideration is
given to HID settings prior to connecting
any I/O boxes to the network, especially if
future networking of standalone systems
is a possibility.
As an example, consider two Calrec
systems, each with several I/O boxes with
HIDs starting at ‘1’ and set in ascending
numerical order. If you later decide to
network these two systems together you
will have multiple I/O boxes with the same
HIDs on the network.
In this scenario when a Show/Memory
containing patches is loaded, there is
no way of controlling which patches will
be made to which I/O box. Instead we
recommend using a separate numbering
range for each standalone system so no
conflicts can arise in the future.
ID configuration
Each I/O box in a system needs to be
given a unique hydra ID (HID), set using
DIP switches accessible from the rear of
a fixed format box, or on the side of the
controller card within a modular I/O box.
I/O box IDs are pre-set to ‘0’ at the Calrec
factory to effectively set the boxes into
an ‘off’ state to avoid issues in the event
of multiple boxes being placed on the
network with the same HID.
Before connecting each I/O box to the
network ensure you set a unique HID by
following the instructions on the following
pages.
Note, Some customers may find
that their I/O boxes have been pre-
configured with unique HIDs at the
Calrec factory, prior to dispatch.
Changing an I/O Box’s HID
If you have already connected and
powered up an I/O box and then wish to
change its HID you will need to follow
these steps:
1. Power off the I/O box.
2. Change the HID to a new, unique value
by following the instructions on the
following pages.
3. Remove the I/O box from the console’s
required list (see Summa User Manual)
4. Remove the I/O box from Hydra
database in H2O (‘I/O box and port
labels’ tab).
5. Remove Shows/memories/patches
which reference the I/O box.
6. Reset the router by simultaneously
pressing ENABLE and ROUTER on
the front of the core.
7. Once the reset has completed, power
up the I/O box.
If you plan to reuse the original HID it
is important that you follow these steps
including removing patches (or entire
Show/memories) which patch to the
original I/O box, otherwise these patches
may be made to the ‘new’ I/O box next
time the Show/Memory containing the
patch is loaded.
Port Labels and SW-P-08 Settings
When you change a box’s HID, its
associated port labels and SW-P-08
settings will be lost. If you would like to
back them up to re-associate with the
I/O box once you have changed the HID,
simply follow these steps:
1. Open Chrome and navigate to H2O.
2. Export Label and SW-P-08 information
to a CSV file by following the
instructions in the ‘Label & SW-P-08
Data Import/Export’ section of the
H2O User Guide.
3. Open the CSV file in an editor, such as
Microsoft Excel.
4. For each entry, update the HID to your
new value.
5. Import the CSV file back in to H2O for
the correct I/O box.
Duplicate HIDs
What happens if you connect two I/O
boxes with the same HID to your Hydra2
network?
Firstly, the system will be unpredictable
in terms of its use of the ports across the
two boxes. A patch to output port 1 could
pick either box’s output port to patch to,
and each time the patch is made, either
port may be chosen.
Secondly, there will be confusion between
different I/O types. For example, in the
scenario above one I/O box may be
analogue and the other digital.
Spare/Replacement I/O Boxes
Replacement I/O boxes of equivalent
type should be set with the same IDs
as the units they are replacing to allow
them to function as drop-in replacements
with existing user memories, requiring no
further configuration.
Care should be taken when setting HIDs
to avoid accidentally duplicating the same
HID on more than one box.
Do not add extra I/O to the system
unless you are confident it will not
cause a conflict on the network.

CALREC Putting Sound in the Picture 15
SETTING HYDRA IDsFOR FIXED FORMAT I/O
The 8-way DIP switch on the rear
of all fixed format I/O boxes is set
as an 8-bit binary representation
of the HID value with the left hand
switch used for the most significant
bit, and the right hand switch for
the least significant bit. A switch in
the down/off position represents a
binary 0 and a switch set in the up/
on position represents a binary 1.
Each switch/binary-bit equates to a
decimal value, starting at 1, for the
least significant bit. The remaining
switches are double the value of their
less significant neighbour, making the
8th/most significant bit equate to a
decimal value of 128.
All fixed format I/O box ID switches are
orientated the same way, though some
boxes, such as MADI units, use a different
style switch with more pronounced
labelling. Ignore any labels on the switch
itself and always refer to the Calrec
labelling on the surrounding panel which
will show the most significant bit switch on
the left and the binary 1 position as up.
Address 2
Some I/O boxes, such as MADI units,
are fitted with 2 banks of DIP switches—
Address 1 and Address 2—to provide a
16 bit ID and therefore a greater range
of values. Please note that only ID
values between 0 and 255 are currently
supported. Any DIP switches labelled
Address 2 should all be set to the off ‘0’
position.
SETTING THE HID ON A FIXED FORMAT I/O BOX

16 SUMMA Networked Audio Production System Getting Started
SETTING HYDRA IDsFOR MODULAR I/O
The HID for modular I/O boxes is set
by a DIP switch on the controller card
and is only accessible by removing
the card. Refer to the Hydra2
installation manual and ensure ESD
precautions are observed before
removing any modular I/O box cards.
Ignore any labelling on the DIP switch
itself and refer to the Calrec labelling
printed on the circuit board around the
switch to clarify its orientation.
When viewing the card from the side, the
most significant bit is on the left and the
least significant bit on the right. Pulling a
switch towards you sets it as a binary 1,
away from you as a binary 0.
The following illustration shows the ID
switch on the modular I/O controller card.
A decimal value of 39 is used for the
example. These illustrations, along with
simple instructions, are displayed on the
top of the modular I/O box itself.

CONNECTING I/O TO THE CORE
All I/O that you wish to use with
your summa system should be
connected to the console core router
card(s) using fibre or copper cable
