Chapter 1 Cisco 7200 VXR Product Overview
Field-Replaceable Units
routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 series
Chassis Interface (RSP7000CI), in the Cisco AS5800 Universal Access Server,
and in the Cisco uBR7246 universal broadband router.
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 1-63.
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 10BASE-T Port Adapter Installation and Configuration.
This configuration note accompanies every PA-4E port adapter that
is shipped from the factory as an installed item in a Cisco 7200 VXR
router or as a FRU. The configuration note is also available on the
Documentation CD-ROM and on CCO.
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.
