Cisco 7200 Series Port Adapter Hardware Configuration Guidelines
OL-3875-11
Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements
Bandwidth and Bandwidth Point Requirements
Note
You can use a Cisco 7200 series router with a port adapter configuration that exceeds the preceding
guidelines; for example, if you have a redundant port adapter installed that is not in use. However, to
prevent anomalies from occurring while the router is in use, we strongly recommend restricting the port
adapter types installed in the router according to the guidelines listed above.
Additionally, your port adapter configuration must be within the above guidelines before the Cisco
Technical Support Services will troubleshoot anomalies that are occurring in your Cisco 7200 series
router.

1.
Processor memory requirements are used when you determine port adapter installation guidelines for a Cisco 7200 series router.
2.
Not applicable.
3.
Bandwidth points for low-bandwidth port adapters are not required when you determine port adapter installation guidelines for a Cisco 7200 VXR router
that has an NPE-400, NPE-300, or NSE-1 installed; that is, low bandwidth means 0 bandwidth points.
4.
The PA-SRP-OC12 port adapters connect to both PCI buses; therefore, the total bandwidth points (300) are divided equally between the two buses. You
must calculate the total bandwidth points by adding 150 bandwidth points to each bus.
5.
When using only 1 port of the two ports available, the PA-2FE (TX) uses only 200 bandwidth points, and is an allowed usage. See also the
“Messages
for One Port Use of Specific Port Adapters and an I/O Controller” section on page 1-22
for information on supported Cisco IOS releases and an error
message.
6.
For use only in Cisco 7206 or Cisco 7206VXR router shelves in a Cisco AS5800 Universal Access Server.
7.
The I/O controller with a Gigabit Ethernet port and an Ethernet port (C7200-I/O-GE+E) operates only in Cisco 7204VXR and Cisco 7206VXR chassis
with the following network processing engines: NPE-400 and later network processing engines or the network services engine.
8.
The I/O controller with two autosensing Fast Ethernet/Ethernet ports (C7200-I/O-2FE/E) operate only in Cisco 7204VXR and Cisco 7206VXR chassis
and with the following network processing engines: NPE-225 and later network processing engines or the network services engine.
9.
When using only 1 port of the two ports available, this I/O controller uses only 200 bandwidth points, and is an allowed usage. See also the
“Messages
for One Port Use of Specific Port Adapters and an I/O Controller” section on page 1-22
for information on supported Cisco IOS releases and an error
message.
10. The Fast Ethernet port on the I/O controller (C7200-I/O-FE) does not operate in a Cisco 7202 router.
11. This port adapter is not supported in Cisco 7200 VXR routers.
12. See the
Integrated Service Adapter and Integrated Service Module Installation and Configuration
documentation for information on compatibility with
the VPN Acceleration Module, as well as information on specific behaviors of these products when used with each other, and specific commands to use
to enable or disable them
13. See the
VPN Acceleration Module Installation and Configuration
documentation for information on compatibility with Cisco ISA Service Adapter and
Cisco ISM service adapter, as well as information on specific behaviors of these products when used with each other, and specific commands to use to
enable or disable them.
14. For use with Cisco 7200 VXR routers only until release of Cisco IOS Release 12.2(2)T.
