Sirius 600 www.snellgroup.com Introduction
Issue 1 Rev 3 Page 4 © 2014 Snell Limited
1. Introduction
The Sirius 600 range consists of four self-contained, multi-format, multi-level signal routers
with a maximum size of 512 x 512. The use of a generic broadband crosspoint has given the
Sirius 600 range the ability to pass any digital signal type, up to and including 3D-SDI,
through the same crosspoint matrix. Input and output processing is performed by modular,
signal specific, Input/Output cards. Standard input and output cards have eight signal paths,
and are available in SD-SDI, HD-SDI and 3G-SDI and AES audio formats. The system is
further enhanced by the addition of video and audio ADC and DAC cards, enabling full
analogue/digital conversion as required.
The Sirius 600 range includes four sizes of chassis, each offering specific maximum router
configurations, but using the same input and output cards, and thereby offering efficient and
cost effective upgrade paths. The Sirius 600 range may be summarized as follows:
• Sirius Gold (39U): Maximum of 512 x 512 (up to HD-SDI rates)
• Sirius 630 (16U): maximum 256x256 using four 256x64 crosspoint cards
• Sirius 620 (7U): maximum 128x128 using four 128x32 crosspoint cards
• Sirius 610 (4U): maximum 64x64 using two 128x32 crosspoint cards
The Sirius 610 (4U) frame can offer:
• between 128x1 and 64x64 (increments of 8) routing, all signal types
The Sirius 600 series design philosophy provides a solution for systems undergoing an
analogue to digital, or SDV to HDTV transition, and provides the platform for an array of
modular enhancements and options. The Sirius 600 product range includes:
• SDV crosspoint modules, for cost effective routing up to 360Mb/s
• HDTV crosspoint modules, for routing all digital signals up to 3 Gb/s
Sirius 600 series uses the Snell Nebula control system, common to many Snell routers,
allowing the direct connection of up to 32 control panels or Under Monitor Displays to the
chassis. The user may select a pre-configured database to get the system up and running, or
use a Windows based editor to customize the router to their own specific requirements.
Nebula also allows the configuration of crosspoint salvoes, route protects and inhibits,
multi-level operation and connection to Snell's Aurora router controller. The Sirius 600 chassis
may control other Sirius 600, Freeway or Halo routers as slave systems using a control bus
expansion connection, although an existing Freeway cannot control any Sirius 600 router.
Sirius 600 has been designed with true input and output monitoring available as an option.
Additional modules have analogue and digital, video and audio outputs, such that any input or
output may be accessed, on both video and audio levels within a single frame.
1.1 Design Features
Sirius 600, despite it's innovative design, has many of the features associated with Snell's
hardware products, giving it a robustness and ease of maintenance essential in critical signal
applications. All modules are 'hot-pluggable'; surge suppression circuitry, and phased
power-up allow quick and safe module swapping, this is further aided by the retention of
crosspoint and configuration data in non-volatile control card memory. All modules are
addressed by their position in the frame, rather than by jumper settings, and the careful
consideration of power routing and driver voltage levels ensures that mis-plugged modules
are not damaged.
If dual control cards are fitted; crosspoint, configuration and database information is
synchronized between the two cards. Changeover is automatic in the event of failure, and the
tri-state buffering of all control signals ensures that changeover is also transparent to both the
internal and any external systems.

Sirius 600 www.snellgroup.com Introduction
Issue 1 Rev 3 Page 5 © 2014 Snell Limited
All the frames are non-expandable, therefore there is no requirement for signals to be bussed
or 'rippled' through crosspoint cards, all signals are routed point to point, using discrete
buffering, thereby maintaining signal integrity and quality. This approach also allows the
router to be part equipped or 'partitioned' with no loss of functionality. A further advantage of
maintaining a short, quality, signal path is that the re-clocking of digital signals on the output
stage, usually a necessity on traditional routers, is no longer an essential requirement.
Because some of the digital signal types currently used do not necessarily benefit from
re-clocking, a full specification, non-re-clocking router is a distinct advantage. This allows the
user to opt for non-re-clocking outputs without degrading the system specification, and at the
same time providing a cost-effective and signal-independent solution.
The Sirius 600 video router operates in a mixed standard environment, providing both 525
and 625 line references are supplied to the frame, ensuring SMPTE RP168 compliant
switching between sources of the same standards. The Sirius 600 audio router is designed to
work with mixed stereo and mono channels, where the necessary combining and switching is
applied at both the input and output stages, for both the analogue and digital formats. The
audio signal mode of each channel may either be stored in the database, or configured
dynamically from a standard master control panel.
The dual redundant power supply units only supply 48 volts, all modules convert this to the
required levels locally, which not only makes the power routing simple, but provides thorough
power rail de-coupling between modules.
1.2 Sirius 600 User Manuals
Sirius 600 is a modular product with an unknown number of permutations of router
configuration, a single user manual for all users is not possible. What each user will receive is
a core manual, giving general information for the Sirius 600 frames, control card configuration
details and database information. They will also be supplied with supplement user manuals
describing each crosspoint, input and output module currently available. Finally, the Nebula
User Guide will also be supplied, along with the database editor software, allowing the user to
configure the system to their own requirements. Module upgrades and additions will only
affect the appropriate supplements, and simplify the documentation process.
General information on Snell products is now contained in a separate user manual, detailing
warranty, customer support and EMC compliance data.
In summary, the following user manuals are available:
• Sirius 600 user guide: Sirius Gold (39U), Sirius 630 (16U), Sirius 620 (7U), Sirius 610

3. Installation
The Sirius 600 range of routers is supplied in 16U, 7U or 4U frames with integral power
supplies and cooling. All cards and modules are accessible from the front after the door has
been opened or removed, and all signal and control cables are connected to rear panels.
Ventilation air is taken from the left hand side of the frame, and exhausted on the right hand
side, and this must be considered when mounting the unit (see Section 3.12).
If you experience any difficulties with any Sirius 600 frame, please refer first to Section 8 -
Trouble Shooting, and then if you are still having difficulties contact customer support as
detailed in the General Information user manual.
3.1 System Components
The following table identifies all major Sirius 600 components; all modules are marked with a
four-digit part number. Use this table to check the compatibility of module types in your
system:
3.2 Sirius 600 Cards 1 & 2 Compatibility
Snell's Sirius 600 Router range contains both established and current products. The range
can be classified as Series 1 and Series 2.
Table 1. identifies whether the card is a series 1 or series 2 card and gives an indication on
compatibility. Please read section 3.2.1.1 The table is correct at time of printing; if you are in
any doubt please consult your Snell representative.

3.5 Sirius 610 (4U) Frame Options
Fig 4. shows that it is possible to replace output cards with input cards in a Sirius 610 (4U)
frame. This 'trade-off' not only results in a non-square router, but also allows for the number of
crosspoint cards to be reduced in certain configurations, giving a highly flexible and cost
effective solution for a number of applications, see Table 5.
3.6 Card Locations in Sirius 610 (4U) Frame - Audio Only
This frame only allows a mix of audio cards as an AES crosspoint card is fitted. The rear
connections can either be balanced or unbalanced but separate input and output cards must
be used.
This router CANNOT be mixed format and it must be equipped to use separate input and
output AES cards.
It is important to set the switches on the AES crosspoint card to match those of the control
cards.
No other switch settings are valid.

3.7 Card Locations in Sirius 630 (16U) Video or Unbalanced AES Router
Frame
The Sirius 630 (16U) frame uses physically larger crosspoint cards than used in the Sirius
610 (4U) and Sirius 620 (7U) frames, and each is equipped with 256x64 crosspoints. These fit
vertically into the centre of the frame, and the user must note that the two on the right side of
the frame are fitted 'upside down' with respect to the two on the left.
The input and output cards are the same types as used in the Sirius 610 (4U) and Sirius 620
(7U) frames, and occupy four 'quadrants' of the chassis, all with their card ejectors towards
the outside of the frame.
If input and output monitoring is required, four cards are fitted, one serving each frame
quadrant, the master output card being in the top left hand position.
If the frame is to be fitted with any video DAC cards, these will receive their analogue and
digital references respectively from the monitoring cards fitted in positions 1 and 4, which in
turn must be supplied with a suitable black and burst signal. This will not provide input and
output monitoring, which if required will need the full compliment of four monitoring cards. The
user must refer to the Sirius 600 monitoring user guide for full details.
The fan and power supply modules are the same as used in the Sirius 610 (4U) and Sirius
620 (7U) frames. With four power supplies fitted, the frame has full power supply redundancy,
since only two are required to power a fully equipped frame, although it is necessary to fit four
power supplies in order to achieve adequate cooling.

3.8 SDV Router Configurations
Table 9. lists all the Serial Digital Video configurations:
Fig 5. shows card positions for all the configurations.
In a Sirius 610 (4U) frame, input cards may be 'traded off' against output cards to create
non-square routers and use the surplus crosspoints. This is not possible in a Sirius 620 (7U)
frame where the full crosspoint capacity is being used, however, any Sirius 620 (7U)
configuration may be 'sub-equipped' to create smaller router dimensions.
3.9 AES Router Configurations
The 4911 AES crosspoint card is primarily designed for use in the Sirius 610 (4U) frame using
4999 combined Input/Output cards, giving a maximum router size of 128x128, but it may also
be used in other configurations where cost effective AES routing is required. The restriction
with using 4999 cards is that balanced D type connectors only may be used. Unbalanced
AES routers must use 4992/4993 input cards and 4996 output cards, which may then be used
with any crosspoint cards, with the knowledge that the 4911 is the most cost effective.
The 4911 card has a greater number of crosspoints accessible than the video crosspoint
cards when used in a Sirius 610 (4U) frame, meaning that a 128x64 AES router can be built
using one crosspoint card and separate Input/Output cards. These extra crosspoints cannot
be accessed in a Sirius 620 (7U) frame, for which the 4911 card works as a direct
replacement for the video crosspoint cards, but at a lower cost. These different configurations
must be setup using switches, both on the crosspoint cardand the host control card. The user
must refer to both the control card section of this manual, and the 4911 user guide for full
configuration details.

Table 10. lists the full range of AES router options:
It is noted that the most cost effective option for a balanced AES router is the Sirius 610 (4U)
frame using combined Input/Output cards, this however will result in a 'square' router.
Non-square routers may be constructed using the separate input/output card types, with the
knowledge that the full crosspoint capacity may not be used.
The user should refer to Section 3 of the main Sirius 600 user manual for a front view of card
positions in the Sirius 610 (4U), Sirius 620 (7U) and Sirius 630 (16U) frames, and also for a
full table of non-square router configurations.

multi-level system. See the AES crosspoint user guide for details.

3.10 Inserting and Removing Cards
Fig 6.shows that all card handles locate into the metalwork of the Sirius 600 frame in such a
way that allows easy insertion and removal. Pulling the bottom of the handle outwards will
lever the card out of its socket for removal. When inserting the module, the handle must be
lifted and located in the frame as shown, before using the handle to push the card fully home.
Static precautions must be observed when inserting and removing all system modules.
Cards in the bottom of a Sirius 620 (7U) frame are fitted upside down, and therefore their
handles are at the bottom. In a Sirius 630 (16U) frame, handles are to the left in the left hand
side of the frame, and to the right in the right hand side.
3.11 Ventilation
Each frame employs an internal fan assembly providing horizontal cross ventilation to
maintain a cool, internal, air temperature. Frames may therefore be mounted directly on top of
each other, or other equipment, without the need for vertical separation. Care should however
be taken when mounting frames directly above other equipment to ensure that they are not
subjected to excessive heat from that equipment, and that cooling vents in equipment directly
above or below them are not obstructed.
It is therefore essential during the installation process to observe the following points:
• Do not obstruct the vents on the unit to allow cooling to take place, allow at least
40mm free space on each side of the frame
• Ensure that both the fans and vents have access to the ambient temperature room air
• Do not obstruct cooling vents in equipment directly above or below the frame.
• The door must be fitted and closed to ensure adequate cooling when the unit is pow-
