Field-Replaceable Units Chapter 1 Cisco 7200 VXR Product Overview Note The port adapters installed in the Cisco 7200 VXR routers support OIR. For an explanation of OIR, see the "Online Insertion and Removal" section on page 1-57. All port adapters and service adapters connect to two Peripheral Component Interconnect (PCI) buses on the router midplane. The PCI buses provide a path to packet I/O memory and the system (route/switch) processor. The Fast Ethernet port on the I/O controller connects to a third PCI bus for packet routing and switching. The port or service adapters either provide such services as compression or encryption, or they provide network interfaces to connect the router to external networks. Note Detailed instructions for removing, replacing, and configuring the port adapter types supported on the Cisco 7200 VXR routers are contained in the configuration note for the port adapter. For example, if you plan to replace a 4-port Ethernet port adapter in your Cisco 7200 VXR router, refer to the configuration note PA-4E Ethernet 10BaseT Port Adapter Installation and Configuration. The configuration note is available on the Documentation DVD and on Cisco.com. Caution To ensure adequate airflow across the router's port adapters, a port adapter or a blank port adapter must be installed in each port adapter slot.

Cisco 7200 VXR Product Overview

Note
The port adapters installed in the Cisco 7200 VXR routers support OIR. For an explanation of OIR, see
the
“Online Insertion and Removal” section on page 1-57
.
All port adapters and service adapters connect to two Peripheral Component Interconnect (PCI) buses
on the router midplane. The PCI buses provide a path to packet I/O memory and the system
(route/switch) processor. The Fast Ethernet port on the I/O controller connects to a third PCI bus for
packet routing and switching. The port or service adapters either provide such services as compression
or encryption, or they provide network interfaces to connect the router to external networks.
Note
Detailed instructions for removing, replacing, and configuring the port adapter types supported on the
Cisco 7200 VXR routers are contained in the configuration note for the port adapter. For example, if you
plan to replace a 4-port Ethernet port adapter in your Cisco 7200 VXR router, refer to the configuration
note
PA-4E Ethernet 10BaseT Port Adapter Installation and Configuration
. The configuration note is
available on the Documentation DVD and on Cisco.com.
Caution
To ensure adequate airflow across the router’s port adapters, a port adapter or a blank port adapter must
be installed in each port adapter slot.
