System 5000 Backplane Ethernet Segment Banks
The chassis backplane Ethernet bus consists of 12 Ethernet segments,
divided into two banks of six segments each: segments 1 through 6 and
segments 7 through 12. Each Model 5399 Remote Access Concentrator
module installed in the chassis can be configured to access one bank of
six segments, either segments 1 through 6 or segments 7 through 12. For
more information, see Setting the Backplane Ethernet Segment on page
2-3.

Within a segment bank, the specific segment to which a Model 5399
Remote Access Concentrator module is connected is determined by
setting the segment selection DIP switch on the module. For more
information, see Setting the Backplane Ethernet Segment on page 2-3.

System 5000 Service Port Management
The service port, located on the front panel of the chassis, provides a
switched serial communication link between the service port and any
module in the hub, including the supervisory module. By connecting a
terminal to this port, you can change the configuration parameter values
for the Remote Access Concentrator installed in the hub.
