Product Architecture

Scheduler

The scheduler handles requests from the line cards for access to the CSF. When the scheduler receives a request from a line card for CSF access, the scheduler determines when to allow the line card access to the CSF.

Switch Fabric

Switch fabric circuitry carries the user traffic between line cards or between the RP and the line cards.

Power Entry Modules

The Cisco 12404 router chassis supports two 1100 W online insertion and removal hot swappable PEMs. Each unit is capable of delivering up to 1100 W at –54.5 VDC. The router PEMs are hot swappable and the router must be populated with two PEMs to meet EMI standards.

Caution Do not mix PEM types in the router. In multiple PEM system configurations, all PEMs must be of the same type; either all AC PEMs for AC powered routers, or all DC PDUs and DC PEMS for DC powered routers.

A hardwired DC power source, power cable is required from the site DC power source to the DC PDU on the chassis. The DC power cable leads are 4 American Wiring Gauge (AWG) high strand count wire.

For detailed handling and replacement instructions for the Cisco 12404 router PEMs, see the appropriate configuration note which accompanies each AC PEM, DC PEM, or DC PDU that is shipped from the factory as a FRU.

AC Power Entry Module

The AC PEM (Figure A-6) measures 6.60 inches (16.76 cm) deep by 14.30 inches (36.32 cm) wide by 3.50 inches (8.89 cm) high and weighs 11.0 lbs (5.0 kg).

The router is configured to customer specifications from the factory. If 1 AC PEM is requested, 2 AC PEMs are shipped.

Cisco 12404 specifications

The Cisco 12404 is a robust router designed for service providers and large enterprises, aiming to deliver high performance, scalability, and flexibility in networking. As part of the Cisco 12000 Series, the 12404 is built to address the demands of high-bandwidth applications and a growing number of users in modern networks.

One of the standout features of the Cisco 12404 is its versatility. The router supports various modules for enhanced functionality, including high-speed interfaces, advanced processing capabilities, and additional memory. This modular design allows organizations to customize their router according to specific networking needs and expand as requirements evolve.

In terms of performance, the Cisco 12404 is equipped with a high-capacity forwarding engine that ensures rapid data transfer and low latency. This capability is crucial for businesses that rely on real-time communication, such as VoIP and video conferencing. The router supports a variety of protocols, including IP, MPLS, and Ethernet, making it adaptable to diverse operational environments.

Scalability is another significant characteristic of the Cisco 12404. It can handle thousands of routes and high volumes of traffic, making it suitable for ISPs managing large subscriber bases. With its support for 10 Gigabit and 100 Gigabit Ethernet interfaces, the router can accommodate increasing data loads without compromising performance.

Advanced features like Quality of Service (QoS) enable network administrators to prioritize traffic based on the type or importance of data. This ensures that critical applications receive the bandwidth they need while less essential services are deprioritized, thus optimizing overall network efficiency.

The Cisco 12404 also integrates advanced security measures to protect sensitive data as it flows through the network. With features like Access Control Lists (ACLs), Virtual Private Network (VPN) support, and encryption capabilities, organizations can safeguard their information against potential threats.

In conclusion, the Cisco 12404 presents a compelling solution for organizations seeking a high-performance router with scalability and versatility. By combining advanced routing technologies, modular design, and robust security features, it stands out as a reliable choice for enterprises and service providers looking to optimize their core networking infrastructure.
