 is an INSERTED/BYPASS toggle selection which allows you to 

control whether or not the module’s FDDI-2 front panel ports will connect (insert) to 
the backplane’s FNB-2 rings. 

When set to INSERTED, the module’s FDDI-2 (B and A) ports insert directly into the 
backplane’s FNB-2 primary and secondary rings, respectively.

When set to BYPASS, the module’s FDDI-2 (B and A) ports do not connect to the 
backplane. Therefore, no communications between the FDDI-2 front panel ports and 
the backplane can occur.

 

is an ENABLED/DISABLED toggle selection which allows 

you to control whether or not the module’s FDDI-2 front panel ports (in INSERTED 
status) and their corresponding FNB-2 rings will automatically connect only when an 
active link is detected on the module’s FDDI-2 front panel port(s).

When the (FNB-2) AutoConnect field is set to ENABLED, (and the FNB-2’s FNB 
Status is set to INSERTED), then a connection between the module’s FDDI-2 front 
panel ports and the backplane’s FNB-2 primary and secondary rings will occur 
regardless of an active link being detected on the FDDI-2 front panel port(s).

When the (FNB-2) AutoConnect field is set to DISABLED, (and the FNB-2’s FNB 
Status is set to INSERTED), then a connection between the module’s FDDI-2 front 
panel ports and the backplane’s FNB-2 primary and secondary rings exist only when 
an active link is detected on the FDDI-2 front panel port(s).

front panel A port. 

 

identifies the type of FDDI Port Interface Module (FPIM) that 

resides in the module’s FDDI-2 front panel A port.

front panel B port.
