Maximum number of DICENTIS devices in a string:
–
The max age timer should be set to 22 when RSTP is used for cable redundancy to
prevent a defective cable or powering switch from influencing the system.
– Each time data hops from one switch to another, the age is increased by one. This timer
can be reached or exceeded, because a daisy chain can be used to loop through the
DICENTIS devices.
– This timer (or restriction) cannot be reached when there is no cable redundancy. This is
because 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.
