Connecting H-PCF Cable Optical Ring System Cables
Section 2-2
Optical Ring System in
Token Ring Mode
Connect all the nodes in a ring using H-PCF Optical Fiber Cables.
Begin connection with the rightmost connector (SL1) of the highest node in
the network and connect to the leftmost connector (SL2) in the next lower
node, as shown in the following diagram.
The nodes can be connected in any order, but connect the nodes in the order
of node addresses (i.e., node 1, node 2... node 62) as much as possible to
reduce the effect on the communications time if a wire breaks.
Refer to
2-1-1 Devices Required for Connection
for details on available Opti-
cal Fiber Cables. Refer to page 38
Installing Connectors
for details on con-
necting the Optical Fiber Cables to the Controller Link Board.
Note
1. Always use the specified Optical Fiber Cables.
2. The maximum distance between nodes depends on the method used to
attach the connector to the cable.
2-2-3
Installing Connectors
A special connector is used to connect the Optical Fiber Cable to the Control-
ler Link Support Board.
This manual does not provide details on Optical Fiber Cable preparation.
Connect the nodes in order beginning with the highest node in the network
and continuing on to lower nodes. When connecting a ring, also connect the
end node in the ring to the start node.
• Always turn OFF the computer and backup power supply before connect-
ing Optical Fiber Cables or the backup power supply connector.
• Special tools are required to attach Optical Fiber Cables to the connec-
tors. The cable may disconnect from the connector if the proper tools and
methods are not used during cable assembly.
Connection Procedure
1,2,3...
1. The Optical Fiber Cable’s power supply line is not used, so it can be cut.
2. As shown in the following diagram, secure the Optical Fiber Cable, and se-
cure the holding piece to the mounting bracket. Secure the two cables si-
multaneously for nodes (except the end nodes). Pay attention to the
orientation of the mounting bracket and the connector position when con-
necting the cable from the highest node in the network to the rightmost
connector (SL1), and the cable from the next lower node to the leftmost
connector (SL2).
