Chapter 1 Product Overview
Physical Description
Physical Description
The front of the Cisco 7204 provides access to an I/O controller and up to four network interface port
adapters (see
Figure 1-1 ). The I/O controller contains the following: a 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; an optional Fast Ethernet port. The Fast Ethernet port provides a 100-Mbps connection to the
network.
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 either a single MII port or an MII port and an RJ-45 port (only one port
can be used at a time). Although still supported by Cisco Systems, the I/O controller equipped with the
single MII port was discontinued as an orderable product in May 1998.

The port adapters installed in the Cisco 7204 are of the same type as those installed on the
second-generation Versatile Interface Processors (VIP2s) in the Cisco 7500 series routers, in Cisco 7000
series routers using the 7000 Series Route Switch Processor (RSP7000) and 7000 series Chassis
Interface (RSP7000CI), and in the Cisco uBR7200 series routers. The port adapters installed in the
Cisco 7204 support OIR. For an explanation of OIR, refer to the section
“Online Insertion and Removal”
section on page 1-25 .
Note
The I/O controller does not support OIR. You must power down the Cisco 7204 before removing the I/O
controller from the router.
Port adapter slots in the Cisco 7204 router are numbered from left to right, beginning with port adapter
slot 1 and continuing through port adapter slot 4. Port adapter slot 0 is the Fast Ethernet port on the I/O
controller (refer to
Figure 1-2 ).
