Fast

Ethernet

Port Adapter Family (PA-FE and PA-2FE)

For Cisco 7200, 7300, 7400 and 7500 Series Routers

Cisco Systems offers a family of Fast Ethernet (FE) port adapters optimized for

the specific requirements of campus and enterprise backbones and data centers.

The Cisco FE port-adapter options provide either one or two ports of 100BaseTX

(copper) or 100BaseFX (fiber) Fast Ethernet ports per adapter. Each port can be

configured for half- and full-duplex operation.

Fast Ethernet single-wide port adapters are

available in six models for the Cisco 7200,

7300, 7400 and 7500 Series routers.

• Single-port Fast Ethernet 100BaseTX

(PA-FE-TX)

• Single-port Fast Ethernet 100BaseFX

(PA-FE-FX)

• Dual-port Fast Ethernet 100BaseTX

(PA-2FE-TX)

• Dual-port Fast Ethernet 100BaseFX

(PA-2FE-FX)

Cisco Fast Ethernet port adapters may be

used in an open port-adapter slot on

Cisco 7200, 7301, 7401 Series routers,

open bay within Cisco second- and

fourth-generation Versatile Interface

Processors (VIP2 and VIP4) on Cisco 7500

Series routers or on Cisco 7304 with PA

Carrier Card. Portability between these

systems simplifies ordering and minimizes

overall support and sparing costs.

Single- and Dual-Port

Fast Ethernet Port Adapters

The single- and dual-port Fast Ethernet

port adapters (PA-FE-TX, PA-FE-FX,

PA-2FE-TX, and PA-2FE-FX) provide the

highest packet throughput available for

Cisco 7200, 7300, 7400 and 7500 Series

routers. These adapters are the preferred

choice for campus/enterprise backbones,

data centers, campus-to-WAN connections,

and high-performance routing between

multiple Ethernet virtual LANs (VLANs).

The PA-2FE-TX port adapter supports

either 10- or 100-Mbps configurations

with auto-negotiation. This enables

auto-selection of the appropriate network

speed and duplex mode. The PA-2FE-FX

supports 100-Mbps.
