- Dual-port Fast Ethernet/ISL 100BaseTX port adapter (copper) with RJ-45 connectors
- PA-2FE-TX supports auto-negotiation between 10- and 100-Mbps
- 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 and 7300 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
- Each port configurable for either full- or half-duplex operation
- LEDs to provide quick status checks and problem identification
Cisco Fast Ethernet port adapters may be used in an open port-adapter slot on Cisco 7200 and 7301 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.
