Note Although the processor slots in the seven-slot Cisco 7000 and Cisco 7507 and thirteen-slot Cisco 7513 are vertically oriented and those in the five-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering.

Interface ports on the VIP2 maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the first number in the address changes to reflect the new slot number.

Figure 8-3 shows some of the slot port adapter and interface ports of a sample Cisco 7505 router. The first port adapter slot number is 0, and the second port adapter slot number is 1. The individual FE interface numbers are always 0. For example, on the FE-equipped VIP2 in slot 3 (see Figure 8-3), the address of the FE interface is 3/0/0 (interface processor slot 3, port adapter slot 0, and interface port 0). If a second PA-FE were installed in port adapter slot 1 on this VIP2, its address would be 3/1/0.

Note If you remove the PA-FE-equipped VIP2 (see Figure 8-3) from slot 3 and install it in interface processor slot 2, the address of this FE port becomes 2/0/0.

Note: The MII and RJ-45 interface ports on the first port adapter are both numbered as interface port 0. Only one interface can be used on each port adapter at a time.

You can also identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.

Cisco 7100 Series Ports

In Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and the port number is the physical port. Interfaces in the Cisco IOS software are identified by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial port adapter in slot 3.

Slots in the Cisco 7120 series routers are numbered as shown in Figure 8-4. The fixed LAN interface is slot 0, the fixed WAN interface is slot 1, and the modular port adapter interface is slot 3. On the Cisco 7120 series slots 2 and 4 are not used. Slot 5 is the service adapter.

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.
