C.2 TRANSCEIVER REQUIREMENTS
When you connect an external network segment to an EPIM-A in your 
hub through a transceiver, that transceiver must meet IEEE 802.3 
standards or Ethernet version 1.0 or 2.0 requirements. The transceiver 
must also have SQE disabled.
C.3 THE NBR AS A MULTIPORT ROUTER
An NBR routing image allows you to set up the module as a multi-port 
router. For information on how to upgrade the NBR to perform routing 
functions, and how to configure the NBR as a multi-port router, refer to 
Cabletron Systems Routing Services Configuration Guide.
C.4 THE NBR-420/NBR-620 AND BRIMS
The example in Figure C-1 illustrates just one possible NBR-620 BRIM 
configuration. The NBR620/BRIM combination provides various 
connection possibilities, depending on the BRIM(s) you use. Refer to 
individual BRIM manuals and/or Cabletron Systems Routing Services 
Configuration Guide 
to better understand the capabilities of each device.
