included in the type of product used, then position 2 is not used.
 If optical port is not included in the type of product used, then both
position 1 and 2 are not used.
6.3 Introduction of Alarm
Two abnormal events are defined for ISF series products, i.e. connection interruption
of optical port and PWR1 main power source fault. The switch will notify the user
by way of switching over relay when an abnormal event occurs or is eliminated.
The relay is provided with 3 contacts: one normally open, one normally close and one
common terminal. Corresponding relationship is shown in the following diagram.
When the switch is under normal operational state, the two ports corresponding to
SAFE will be in closed circuit (switched on) state and the two ports corresponding to
FAIL will be in open circuit (switched off) state; when the switch is not energized or
is under abnormal operation state, the two ports corresponding to SAFE will be in
open circuit (switched off) state and the two ports corresponding to FAIL will be in
closed circuit (switched on) state. Alarm output of relay is equivalent to a single-pole
double-throw switch, which is generally connected with external DC power source
and with alarm lamp circuit. In order to ensure normal operation of relay switch,
parameters of electric circuit must satisfy the following requirements simultaneously:
maximum voltage 220VDC, maximum current 2A, and maximum switching power
60W.
Note:
 Port connection interruption alarm can be enabled or disabled via dip
switch; RWR1 main power source fault alarm is constantly enabled.
 When alarm event occurs, triggered relay will maintain alarm state.
Relay will resume to normal state only after all alarm events are
eliminated.
6.4. Introduction of Ring Network
ISF industrial Ethernet switch can be formed into a single ring. Adopted with
independently developed iRing Ethernet ring protection protocol, and ring can be
formed directly without any configuration, capable of plug and play. It can be widely
applied in the fields of electric power, transportation, energy, water treatment,
automatic control of large-scaled plant and office dispatching.
iRing Ethernet ring protection protocol is a privately-owned ring network protocol
independently developed by Beijing InHand. iRing Ethernet ring protection protocol
defines roles of nodes in the ring network and transmits protocol packets via VLAN
control, thus realizing protection of ring network in a mutually cooperated manner,
allowing rapid switchover upon occurrence of fault in ring network or upon recovery
of fault at a switchover time within 50ms and without generating closed loop during
the process.
iRing Ethernet protection system is suitable for topological structure of single-ring
network and can treat and recover single-point fault in ring network effectively. Speed
of topological convergence is rapid and it is unrelated to number of nodes in ring
network; no loop will be generated for treatment/recovery of multiple-point faults in
ring network.
One set of ISM network management switch must be used in each ring, serving as
master node for ring network protection. For network topology, please refer to 8.2.1
“Ring network”.
