13 DECrepeater 90FS Installation and Configuration
Installing the Module (Cont.)
Connecting the Cables
1 Determine the fiber-optic port configuration
Before connecting the fiber-optic cables, determine whether the ports are to be
configured as redundant pairs or as separate independent ports. The default
configuration is separate independent ports.
Refer to the section titled Redundant Fiber-Optic Link Configuration for more
information. (Refer also to HUBwatch Online Help.)
If you are configuring the fiber-optic ports as:
•
Redundant pairs, go to step 2.
•
Separate independent ports, go to step 3.
2 Connect the fiber-optic cables for redundancy
NOTE: You must configure the ports using HUBwatch before
connecting the cables. Failure to do so can create a LAN
loop which could bring down that segment of the
network.
a. Select the module and ports to use as the master and the modules and ports
to use as the responders or non-responders.
b. Using HUBwatch, assign the master ports and the responder ports.
c. Following the procedure in step 3, connect the master’s primary port cables
to the master’s primary port.
d. Connect the other end of those cables to the remote primary port.
e. Connect the master’s secondary port cables to the master’s secondary port.
f. Connect the other end of those cables to the remote secondary port.
