Attaching PA-FE Port Adapter Interface Cables

Step 2 For the PA-FE-TX, attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 7-3.

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the PA-FE-TX-equipped system and is a required component for proper system operation.

Caution To prevent problems on your PA-FE and network, do not simultaneously connect RJ-45 (or SC) and MII cables to one PA-FE. On a single PA-FE, only one network connection can be used at one time. Only connect cables that comply with EIA/TIA-568 standards. (See Table 1-1 and Table 1-2 in the “Receptacles, Cables, and Pinouts” section on page 1-5 for cable recommendations and specifications.)

Step 3 Attach the network end of your RJ-45 (SC) or MII cable to your 100BaseT transceiver, switch, hub, repeater, DTE, or other external 100BaseT equipment.

Note After your MII transceiver is connected and the PA-FE interface is configured as up, you can verify that your MII transceiver responds to physical sublayer (PHY) address 0 by disconnecting the transceiver from the MII receptacle; if the PA-FE interface goes down, then your MII transceiver responds to PHY address 0.

This completes the PA-FE port adapter cable installation.

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.
