At the menu point Hardware Setting it is possible to select the two modes master or
slave. The switch which is configured in master mode is doing the ring manager
functions to avoid the multiplication of the data.
If one connection or one device fails this information is forwarded to the ring manager
(master) by a special protocol. The ring manager keeps the operation of the complete
segment up.
Advantage of this solution is that the ring manager itself has not to be redundant,
because if the manager fails the data can not be multiplied. The segments stays under
operation.
To avoid that the signaling in case of failure has no affect on other rings, it is possible
to define different rings with numbers from 0 to 255 by the network management.
All switches with ring functionality are having the management features included and
are offering the detection and signaling of any failure.
With this concept a limitation in regards to the maximum ring length is not given.
Safety Notes
WARNING:
Infrared radiation as used for data transmission within the fiber optic, although
invisible to the human eye, can nevertheless cause damage.
To avoid damage to the eyes:
never look straight into the output of fiber optic components – danger of blinding!
cover all unused optical connections with caps.
commission the transmission link only after completing all connections.
The active laser components used with this product comply with the provisions of
Laser Class
1
.
DANGER:
Conductive components of power and telecommunications networks can carry
dangerously high voltage.
To avoid electric shock:
Do not carry out installation or maintenance work during lightning storms.
All electric installations must be carried out in accordance with local regulations.
