Chapter 1 Cisco uBR7200 Series Overview
Cisco uBR7200 Series Network Interface Overview
Cisco uBR7246
The two port adapters (slot 1 and slot 2) and the four cable interface cards (slot 3 through slot 6) in the
Cisco uBR7246 provide the connection between the router’s three PCI buses (mb0, mb1, and mb2) and
external networks. Bus mb0 is for the optional Fast Ethernet port on the I/O controller (slot 0); bus mb1
is for port adapter slot 1, and cable interface card slot 3 and slot 5; and bus mb2 is for port adapter slot 2
and cable interface card slot 4 and slot 6.
See
Figure 1-3 on page 1-6
for slot locations and slot numbers. The number of logical interfaces depends
on the type of port adapter or cable interface card.
