Transition Networks 

  

Note:  The FBRM/BFFG Devices does not have configuration switches. 

 

The FBRM/BFFG series Devices features can be configured via USB, MMU, or IP. 
Table 3 explains the configurable parameters of the Devices. 

 

AutoCross 

When the AutoCross feature is active, it allows the use 
of a straight-through (MDI) or crossover (MDI-X) 
copper cable when connecting to 10/100Base-T or 
10/100/1000Base-T Devices. AutoCross determines the 
characteristics of the connection and configures the 
Devices to link up automatically. This occurs regardless 
of the cable configuration:  MDI or MDI-X. (Transition 
networks recommends leaving AutoCross in default 
mode, “enabled.”) 

(10/100Base-T or 
10/100/1000Base-T) 

Automatic Firmware 
Upgrades 

The Device has an automatic firmware upgrade feature. 
This feature applies to a communication link between a 
local peer and its remote peer Devices connected via a 
fiber optic cable. If the remote passive peer Device is not 
in Active Mode and a local active peer Device detects a 
different firmware revision on its remote passive peer  
Device, the local active Device will force a bootload 
condition and download its firmware revision to its 
remote passive peer Device.  

Note  The local Device could have a different firmware 

revision (newer or older) than its remote peer. In 
either case, the firmware revision on the local 
Device will replace that of its remote passive 
peer. 

Note:  The firmware of the local active peer Device 

should be upgraded before the remote passive 
peer Device to ensure that the correct firmware 
version is on both Devices.
