LEDs

Description and Power Source

 

 

2 PCMCIA

Activity LEDs (one per PCMCIA slot) light when the slot is accessed. The

 

LEDs receive power from the switched slot voltage.

 

 

4 RJ-45

Ethernet port LEDs are used in conjunction with the RJ-45 Ethernet

 

connector. The LEDs indicate link activity, port enabled, data transmission,

 

and data reception.

 

 

2 Ethernet connection

The Ethernet connection LEDs (labeled Primary), when on, identify which

 

of the two Ethernet connections is selected. Because both ports are

 

supported on the PRP, the LED on port ETH0 is always on. The ETH1 LED

 

goes on when it is selected.

 

 

Alphanumeric displays

The alphanumeric LED displays are controlled directly by the MBus and

 

provide information about the system status during the boot process.

 

Alphanumeric displays are organized as two rows of four characters each.

 

The displays’ content is controlled by the MBus module software. Both

 

rows of the display are powered by the MBus module.

 

After the boot process, the LEDs are controlled by the Cisco IOS software

 

through the MBus, and display messages designated by the Cisco IOS

 

software.

 

 

Asynchronous Serial Ports

The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow you to connect external serial devices to monitor and manage the system. Both ports use RJ-45 receptacles.

The console port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. The auxiliary port provides a data terminal equipment (DTE) interface and supports flow control. It is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

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.
