2.4 Power Supply
Connect the supplied power cables to the Main POWER ports of the devices
(CATCenter, UCON, UCON-a, UCON-s, and UCON-IP).
A redundant power supply can be optionally connected to the Red. Power port.
To do so, use the optionally available power supply component Power-
SetX/TypeX (type depends on the device ordered).
2.5 Installing the Expansion Unit
The number of targets that can be connected can be increased to 512 (1024,
2048) by cascading. This number of targets is reached within 2 cascade levels.
128 targets can be connected within the first cascade level. The maximum
number of 512 targets is reached in the second cascade level.
The CATCenter devices must be connected to each other for cascading. You
can use a common CAT cable to create a connection between two CATCenter
units. We recommend the following for this purpose:
• PRO-X cable for lengths up to 20 meters
•
K-C7-LD-x cable for lengths over 20 meters
Make sure that the total distance between the CATpro2 and UCON-a does not
exceed 100 meters, or 300 meters for the UCON and UCON-s.
The remainder of this installation description pertains to a CAT cable.
The master device has a total of 32 CPU ports available for cascading.
Assuming that 8 consoles are connected to the master device and all of them
are to access all targets, then one CPU port has to be used for cascading every
console connection. Therefore, 8 CPU ports have to be used on the master
device so that all 8 consoles can continue to access all connected targets.
If, on the other hand, you only have one console then you only have to use one
CPU port on the master; this is identical to the method described above.
In general, the following applies: For every console access
implemented on the slave, the same number of CPU ports must be
available on the master!
