3.5.4 Small linking of several rho4.0 with 8-fold switch
Several rho4.0 can be linked with 8-fold switches through cascading of
the switches. The maximum cascading number according to the manu-
facturer indication is to be taken into account.
According to the regulations according to IEEE 802.3, a maximum of 4
switches can be cascaded according to the following connection dia-
gram.
If more rho4.0 are to be linked than it is possible to connect to 4 switches
maximum, a Backbone Network Topology with coaxial Ethernet cable
must be used.
Connection diagram
For the connection of the rho4.0 to the switch, uncrossed 1:1 cables are
to be used.
. For the connection from switch to switch, a power controller for
crossed or uncrossed cables must be taken into account if there is
one. If the controller is set on uncrossed, uncrossed cables may be
used.
