LEDs

The PA-FE-TX and the PA-FE-FX have an enabled LED, standard on all port adapters, and a bank of three status LEDs for the ports. After system initialization, the enabled LED goes on to indicate that the PA-FE has been enabled for operation. (The LEDs are shown in Figure 1-7.)

The following conditions must be met before the enabled LED goes on:

•The PA-FE is correctly connected and receiving power.

•The FE-equipped card or chassis contains a valid microcode version that has been downloaded successfully.

•The bus recognizes the PA-FE port adapter or PA-FE-equipped VIP2.

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not go on.

Following are the three status LEDs and an explanation of what each indicates:

•MII—On when the MII port is selected as the active port by the controller.

•Link—When the RJ-45 or SC port is active, this LED is on when the port adapter is receiving a carrier signal from the network. When the MII port is active, this LED is an indication of network activity, and it flickers on and off proportionally to this activity.

•RJ-45 (or FIBER on PA-FE-FX)—On when the RJ-45 (or FIBER) port is selected as the active port by the controller.

Either the MII LED or the RJ-45 (or FIBER) LED should be on at any one time; never both.

Receptacles, Cables, and Pinouts

Each Fast Ethernet port on the PA-FE-TX has an RJ-45 connector to attach to Category 5 unshielded twisted-pair (UTP) for 100BaseTX, and a MII connector that permits connection through external transceivers to multimode fiber for 100BaseFX, or to Category 3, 4, and 5 UTP or foil twisted-pair (FTP) for 100BaseT4 physical media. Only one connector can be used at one time. The RJ-45 connection does not require an external transceiver. The MII connection (a 40-pin, D-shell type connector) requires an external physical sublayer (PHY) and an external transceiver.

Each Fast Ethernet port on the PA-FE-FX port adapter has an SC-type fiber-optic connector for 100BaseFX, and an MII connector that permits connection through external transceivers to multimode fiber for 100BaseFX, or to Category 3, 4, and 5 UTP or STP for 100BaseT4 physical media. Only one connector can be used at one time. The MII connection (a 40-pin, D-shell type connector) requires an external physical sublayer (PHY) and an external transceiver.

PA-FE-FX, PA-FE-TX specifications

Cisco Systems PA-FE-TX and PA-FE-FX are essential components in the realm of network switching and connectivity. These Peripheral Adapter modules are designed for use in Cisco 7000 series routers, catering to the needs of high-performance networking and offering robust features.

The PA-FE-TX module is equipped with fast Ethernet ports that provide high-speed network connectivity through twisted-pair cabling. This module supports 10/100 Mbps data rates, making it ideal for connecting end-user devices to the network while ensuring compatibility with existing infrastructure. Its auto-sensing capability facilitates smooth integration into varying network environments, allowing for seamless communication and data transfer.

On the other hand, the PA-FE-FX module is tailored for fiber optic connections, enabling high-speed data transmission over longer distances. This module supports multimode and single-mode fiber options, catering to diverse connectivity requirements. The PA-FE-FX is essential for organizations that require extended reach and minimal signal degradation, making it suitable for large campuses, data centers, and urban networking.

Both modules leverage Cisco's advanced technologies, including Quality of Service (QoS) capabilities and enhanced security features. These protocols ensure efficient bandwidth management and prioritize critical applications, improving overall network performance. Additionally, they support features such as VLAN (Virtual Local Area Network) tagging, enabling network segmentation and improved traffic management.

The physical design of these modules adheres to Cisco's standards, ensuring easy installation and hot-swappable capabilities. This means network administrators can replace or upgrade the modules without taking the entire system offline, providing greater flexibility and reducing downtime.

In summary, Cisco's PA-FE-TX and PA-FE-FX modules are integral components for organizations seeking to enhance their networking infrastructure. With their support for both copper and fiber optic connections, they provide versatile options for connecting devices, extending network reach, and improving data transfer speeds. Their compatibility with advanced networking technologies further emphasizes Cisco's commitment to delivering high-quality, reliable networking solutions for businesses of all sizes.
