System installation overview
It is advisable to participate in the DCN multimedia conference system training before you
install, prepare, configure and operate a DCN multimedia system.
The DCN multimedia system is an IP based conference system which runs on an OMNEO
compatible Ethernet network. It is used for distributing and processing audio, video and data
signals.
The system can be quickly and easily configured as a daisy‑chain configuration (see Typical
system setup, page 7), or as a star configuration:
–Daisy‑chain configuration: Uses dedicated cabling, consisting of CAT‑5e cables including
two additional power conductors.
–Star configuration: Each device is connected with an individual standard CAT‑5e cable.
An Ethernet switch is also required for providing Power over Ethernet (PoE).
Notice!
When Power over Ethernet is used, devices cannot be daisy‑chained.

System installation design and planning
Before you start to install system devices and connect system cabling, you should make a
system design and planning:
– Familiarize yourself with the product and system capabilities.
– Make a cable (connection) plan:
– Calculate the system network cable length.
– Calculate the system power consumption.
– Calculate the required power capacity of the system.
Notice!
DCN multimedia uses the RSTP protocol. If the DCN multimedia system needs to be
connected with the locally present network, please consult the local IT department before
continuing with the installation design.
Notice!
Make sure that the cable lengths and power consumptions do not exceed the specifications:
Not doing so will result in malfunctioning at any moment of the DCN multimedia products and
system.
System capabilities
DCN multimedia product and system capabilities depend on:
– The lengths of the system network cables.
– The number of connected devices.
– The system power supply capacity.
Cable length
System network cables (DCNM‑CBxx) lengths (2, 5, 10 or 25 m) have a direct effect on the
available power supply capacity. The longer the system network cable, the less power supply
capacity is available to drive the connected devices. Therefore, choose the lengths of the
system network cables carefully.
Notice!
Custom network cables, must never exceed the maximum Gb Ethernet specification of 100m
(IEEE 802.3ab). The maximum DCN multimedia system network cable length to be used is
50m.
Keep your network hierarchy as flat as possible. This means having as less levels as possible.
It is recommended not to have more than 7 levels. See the following example: 1 = Root
switch. 2 = Switch.

Figure 4.1: Example: Switch-levels
Power supply capacity
The total system network cable length and connected devices determine the required power
supply capacity. The power within the DCN multimedia conference system is supplied by:
– The Audio Powering Switch (DCNM‑APS) and the Powering Switch (DCNM‑PS), or
– Off‑the‑shelf PoE Ethernet switches.
Calculation tool
The calculation tool can be used to calculate the total power capacity of the system. This
makes the design and planning of the DCN multimedia conference system easier. The
calculation tool uses the power consumption of devices and the system network cable lengths
to calculate the needed system power supply capacity. The calculation tool is on the DVD
supplied with the DCNM‑APS, and on the Bosch website: www.boschsecurity.com.

Hardware requirements
Switches
The following minimal requirements apply to switches:
– 1 Gbit or higher with hardware switching capabilities.
– Quality of Service through differentiated services with 4 or more output queues and strict
priority packet scheduling.
– (Optional) IGMPv3 or IGMPv2 snooping. To optimize bandwidth usage, IGMP snooping
can be used. This is useful in systems with >10 multicast channels, although not
absolutely required. Sufficient performance for handling a large number of IGMP query
responses, depending on the number of (directly or indirectly) connected devices to that
switch. Hardware support for IGMP is strongly recommended.
– (Optional) (Rapid) Spanning Tree support in case redundant networks are used.
– (Optional) SNMPv3 support for switch supervision purposes.
The following table shows recommended switches to use with OMNEO. These managed
switches may offer support for the optional requirements as stated above.

Calculation examples
The following example gives you an indication of the maximum load to each DCNM‑APS or
DCN‑PS socket:
– Socket 2: 50 m + DCNM‑MMD = 12.50 W1
– Socket 3: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W2.
– Socket 4: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W2.
– Socket 5: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W2.
1 For socket 2, the cable power consumption of the cable does not need to be counted.
2 The shortest redundant cable does not need to be counted.
Redundant network
If a system network cable between the devices is accidentally disconnected or broken, signals
cannot be transmitted anymore. To prevent this from happening (and to ensure continuous
operation) a redundant system network cable (4) can be connected to a free high‑power
socket (3, 4, or 5).

2013-08 | V1.0 | Hardware Installation Manual Bosch Security Systems B.V.

Notice!
Make sure one socket can supply power to the complete redundant chain.
Calculation using PoE switches
Select one or more PoE Ethernet switches to supply power to the multimedia devices. Each
DCNM‑MMD must be connected to an individual PoE enabled output of an Ethernet switch.
Notice!
Some PoE Ethernet switches can only supply power to a limited number of ports. Others can
supply power to every port, but the total power the Ethernet switch can supply is limited.
Please consult the documentation of the PoE Ethernet switch used.
Notice!
If the PoE is used, the DCNM‑MMD cannot be configured as a daisy‑chain; redundant cabling
is not required.
Using PoE, the DCNM‑MMD cannot be daisy‑chained connected. Using PoE does not provide
redundant cabling.
