Cisco PA-2FE-TX

2-Port Fast Ethernet 100Base TX Port Adapter 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.

Features
Common Features
100BaseTX (two pairs Category 5 unshielded twisted pair [UTP]) connectivity through an RJ-45 connector
100BaseFX (62.5/125-micron multimode fiber) connectivity through an SC connector
ISL support for high-performance routing between multiple Ethernet VLANs
IEEE 802.1d TB-VLAN support for transparently bridging VLANs
Online insertion and removal (OIR) within Cisco 7200, 7300, 7400 Series routers, enabling users to remove, add, or replace interface processors on line, increasing system availability; OIR for Cisco 7500 is made possible through inserting or removing the VIP2 or VIP4
