Cisco7206 Router Shelf

Network Interfaces

Network interfaces reside on port adapters that provide the connection between the router’s three
peripheral component interconnect (PCI) buses and exte rnal ne twor ks. The Cis co 7206 ha s six s lots
(slots 1 to 6) for the port adapters, one slot for an Input/Output (I/O) controller, and one sl ot for a
network processing engine (NPE). You can place por t adapters in any of the six available slots.
The front of the Cisco 7206 provides access to an I/O controlle r an d up to si x netw ork in terfa ce port
adapters. The I/O controller contains the following:
•Local console port for connecting a data terminal or data terminal equipment (DTE) and an
auxiliary port for connecting a modem or other data communications equipment (DCE) or other
devices for configuring and managing the router
•Two personal computer memory card international association (PCMCIA) slots for Flash
memory cards
•Optional Fast Ethernet port, which provides a 100-Mbps connection to the net work
Note The I/O controller is available with or without a Fast Ethernet port. The I/O controller with a
Fast Ethernet port is equipped with both a media-independent interface (MII) receptacle and an
RJ-45 receptacle; however, only one of these two receptacles can be used at a time.
The port adapters installed in the Cisco 7206 router are of the same type as those installed on the
second-generation Versatile Interf ac e Pr ocessors (VIP2s) in the Cisco 7500 series routers, in
Cisco7000 series routers using the Cisco 7000 series Route Switch Processor (RSP7000) and
Cisco7000 series Chassis Interface (RSP7000CI), and in the Cisco uBR7246 universal broadband
router. The port adapters installed in the Cisco 7206 support OIR. For an ex planation of OIR, see the
“Online Insertion and Removal” section on page1-43.
Note The I/O controller does not support OIR. You must power down the Cisco 7206 before
removing the I/O controller from either router shelf.
Port adapter slots in the Cisco 7206 routers are numbered from left to right from the bottom up,
beginning with port adapter slot 1 and continuing through port adapter slot 6. Port adapter slot 0 is
the Fast Ethernet port on the I/O controller. (See Figure1-20.)
