Redundant server PC

System availability can be improved by connecting a redundant DICENTIS server PC and the
associated components and cables to the DICENTIS Conference System. The maximum
number of Ethernet devices in the largest possible loop (including the root switch) is 22.
The total number of devices allowed in a loop depends on:
– The type of device connected in the loop (for example, DCNM-MMD2 devices consume
more 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 grey line shows the
largest loop. The # sign shows the way the devices are counted.
In the example below up to 17 (22 - 5 = 17) devices can be connected.

For this option to work the DICENTIS Conference System has to be run in combination with
EverRun Enterprise software from Stratus Technologies. For more information, refer to the
Stratus Technologies website.
Other options that can be used for guaranteeing the reliability of the DICENTIS Conference
System include:
– Remote SQL servers.
