The Cisco 7200 Series routers offer a choice of input/output (I/O) controllers to support a variety of applications, bandwidth, and performance for the price. They address the growing demand for high-speed LAN connectivity while reducing the cost per port.
All of these I/O controllers provide the following base functions and features:
•A console port
•Environmental monitoring (voltage monitoring and temperature sensing)
•Fixed Flash memory for storage of boot-helper image
•Two PCMCIA Flash memory card slots
In addition to these features, some I/O controllers also offer Ethernet, Fast Ethernet, and Gigabit Ethernet connectivity without the need for a port adapter.
