If more thanone subnet is required, two types of an ARNI must be used.– OMN-ARNIS (ARNI‑S OMNEO interface): The ARNI‑S is required for increasing the systemsize above 100 DICENTIS devices. It supports up to 450 DICENTIS nodes in its subnet. Italso acts as a DHCP server in its subnet.– OMN-ARNI‑E (ARNI‑E OMNEO interface): The ARNI‑E is required for increasing the systemsize above 450 DICENTIS nodes. It supports up to 450 DICENTIS nodes in its subnet. Italso acts as a DHCP server in its subnet. It can connect up to 40 subnets, each with anARNI‑S.Defining subnets and subnet masksA subnet is a logical, visible subdivision of an IP network. The number of DICENTIS devicesthat can be in the same subnet depends on the subnet mask.A standard class C subnet (255.255.255 or /24) can contain 254 IP addresses. SomeDICENTIS devices have 2 IP addresses. For this reason, Bosch advises to use 255.255.252.0(or /22) as a subnet mask. This allows you to have 1018 IP addresses. The following table liststhe number of IP address per DICENTIS device in a DICENTIS Conference System.Device IP addressesDICENTIS server (optional Meeting Application) 1Client PC running DICENTIS meeting application 1DICENTIS Audio processor and powering switch 1DICENTIS Powering switch 1DICENTIS multimedia device 2DICENTIS discussion device 1DICENTIS discussion device select language 1DICENTIS discussion device voting 1DICENTIS discussion device extended 2DICENTIS Interpreter desk 2DCNM-IDESKVID Interpreter desk with video 3ARNI‑Enterprise 1ARNI‑Standard 1IP camera 1

This timercan be reached or exceeded, because a daisy chain can be used to loop through theDICENTIS devices.– This timer (or restriction) cannot be reached when there is no cable redundancy. This isbecause the power limitation will be reached before the max age restriction is reached.– The timer can be reached when:– you use cable redundancy,– the system is incorrectly wired.

Hardware Installation Manual 2018.09 | V1.8 |4 System installation design and planningBefore you start to install system devices and connect system cabling, you should make asystem 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!The DICENTIS Conference System uses the RSTP protocol when redundant cabling mode isenabled. If the DICENTIS Conference System needs to be connected with the locally presentnetwork, please consult the local IT department before continuing with the installationdesign.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 DICENTIS Conference Systemand products.4.1 System capabilitiesThe capability of the DICENTIS Conference System and DICENTIS products depends on:– The lengths of the system network cables.– The number of connected devices.– The system power supply capacity.Cable lengthSystem network cables (DCNM‑CBxx-I) lengths (2, 5, 10 or 25m) have a direct effect on theavailable power supply capacity. The longer the system network cable, the less power supplycapacity is available to drive the connected devices. Therefore, choose the lengths of thesystem network cables carefully.Notice!Custom network cables must never exceed the maximum Ethernet specification of 100m(IEEE 802.3ab).Keep your network hierarchy as flat as possible. This means having as few levels as possible.It is recommended not to exceed 7 levels. See the following example: 1: 1st level = Rootswitch, 2: 2 nd level = switch, 3: 3 rd level = switch.12 2 2 23 3 3 3Figure4.1: Example: Switch-levels

Thismakes the design and planning of the DICENTIS Conference System easier. The calculationtool uses the power consumption of the devices and the system network cable lengths tocalculate the needed system power supply capacity.The calculation tool is on the DVD supplied with the Audio processor and powering switch andis part of the DICENTIS software DCNM.iso file.

To avoid the switch starts broadcasting unicastpackets because it runs out of space.Disable EEE IEEE 802.3az Most implementations of EEE cause problemsbecause of implementation flaws. A goodimplementation should work, but does not saveenergy since the PTP synchronization avoids this.Therefore, EEE must always be disabled.Disable RSTP (whenno cable loops areused)Rapid Spanning Tree Protocol (RSTP) is requiredwhen (cable) loops are created for redundancy. Whenno loops are created, RSTP needs to be disabled foroptimal operation. When enabled, it can cause slowconnections to the switch.Possibility to createVLANSn.a. VLAN separation is recommended instead of IGMPsnooping, because most switches are unable tohandle the multicast changes in the system. Filteringmulticast data may be necessary for some devices,such as 100 Mb devices (Sony cameras, TVOne, AMX,and others).IGMPv3 IGMPv2snooping inhardwareIGMPv3 or IGMPv2 snooping. To optimize bandwidthusage, IGMP snooping can be used. This is useful insystems with >10 multicast streams, although notabsolutely required. Sufficient performance forhandling a large number of IGMP query responses,depends on the number of (directly or indirectly)connected devices to that switch. Hardware supportfor IGMP snooping is strongly recommended.Requirements whenRedundant wiring isusedStandard SettingsRSTP IEEE802.1D-2004RSTP is used to allow the creation of loops forredundancy.

Themaximum number of Ethernet devices in the loop (including the root switch) is 22. In a systemwith no Ethernet switch(es), the APS is the root switch.The total number of devices allowed in a loop depends on:– The type of device connected in the loop (for example, DCNM-MMD2 devices consumemore power than DCNM-DE devices).– The length of the loop (cable also consumes power).The figure shows how to calculate the number of devices in the loop. The red line shows thelargest loop.

Hardware Installation Manual 2018.09 | V1.8 |5.5 DCNM-CBCPLR Cable couplersCable couplers can be used:– to extend cables,– in a floor pod as break-out box,– as an interface between DICENTIS cable and “standard” CAT-5E cable combined with aseparate power cable,– to insert power locally to the participant devices,– to switch the system on by using two cable couplers and a switch.Cable couplers are delivered in a box that contains 6 cable couplers. They can be used for alltypes of DICENTIS cables.5.5.1 Using a cable coupler to extend a cableThe DICENTIS Cable coupler can be used to extend cables, as it allows you to connectDICENTIS Cable assemblies together. This way, it is possible to connect, for example, three 25m (DCNM-CB25-I) cables together to form a 75 m cable.Note:– The cable length is not allowed to exceed 100 m.– No more than 2 cable couplers can be used in one trunk.DCNM-(A)PSDCNM-(A)PS5.5.2 Using a cable coupler as a break-out boxThe DICENTIS Cable coupler can be used in a floor pod as a break-out box, for example, if youwant to connect temporary devices like a rostrum microphone. The cable coupler can befixated using the screw holes (2.5 mm) or via a tie wrap through the recessed area.Note:– The cable length is not allowed to exceed 100 m.– No more than 2 cable couplers can be used in one trunk.

This can be used, forexample, when standard CAT-5E cabling coming from the technical room has to be connectedwith DICENTIS cable in the conference room.To set this up:1. Open the housing of the cable coupler.2. Connect the power cables to the screw terminals + and -.3. Remove the break-out of the housing to guide the power cables through.4. Create a tension release.!Warning!Risk of electric shock. Exposed power cables are a potential hazard. Make sure all powercables are securely fastened by fixing them with a tie wrap on the inside of the box (seedrawing ‘Creating a tension relief’).5. Close the housing and fix the screw with torque 0.4Nm.Note:– The cable length is not allowed to exceed 100 m.– No more than 2 cable couplers can be used in one trunk.
