Chapter1 Product Overview

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 por t 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 rou ter;

two Personal Computer Memory Card International Association (PCMCIA) slots for Flash memory

cards; an optional Fast Ethernet port. The Fast Ethernet port pr ovides a 100 -Mbps c onnec tio n 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 Cisco7204 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 ri ght, beginning with port adapter

slot 1 and continuing through port adapter slot 4. Port adapter slot 0 is the Fast Eth ernet port on the I/O

controller (refer to Figure 1-2).
