Installing the expansion unit
By cascading, up to 1024 target computers can be connected. This number is
reached within two cascade levels:
256 target computers can be connected within the first cascade level.
The maximum amount of 1024 target computers is reached in the second cas-
cade level.
For cascading the matrix switches of a
CATCenter
system, the matrix switches have
to be interconnected. Use a common category 5 (or better) twisted pair cable.
We recommend our following cables:
PRO-x cable:
to bridge a distance up to 20 m
K-C7/LD-x cable:
to bridge a distance from 20 m on
The master device provides a total of 64
CPU
ports for cascading. Assuming that 16
user modules are to be connected to the master device and all of them are to access
all targets, then one
CPU
port has to be used for cascading. Therefore, 16
CPU
ports
have to be used at the master device, so that all 16 user modules can continue to
access all connected target computers.
If, on the other hand, you only have one user module, one
CPU
port has to be
provided at the master device. This is identical to the method described above.
Important:
For every console access implemented on the slave device, the same
number of
CPU
ports must be provided!
According to this system, the 64
CPU
ports of the master device can be divided into
the following sections for cascading:
CPU Ports 1 - 16:
connect the first slave device within the first cascade level.
CPU Ports 17 - 32:
connect the second slave device within the second cascade level.
CPU Ports 33 - 48:
connect the third slave device within the third cascade level.
CPU Ports 49 - 64:
connect the forth slave device within the forth cascade level.
