Cisco Systems 2500 Series manual

Connecting the DC Power Supply

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.)

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.)

Installing Power Requirements and System Identiﬁer Labels

Follow the directions in this section to place the Power Requirements and System Identiﬁer labels on the rear panel of the Cisco 2500 series routers.

Note The steps in this section are only performed when the router is being converted from an AC power supply to a DC power supply.

Step 1 Remove the Power Requirements label from the sheet of labels included with the power supply. (See Figure 10.)

2500 Series specifications

The Cisco Systems 2500 Series routers are a series of versatile, feature-rich networking devices designed to address the needs of various enterprises and small to medium-sized businesses. Released in the early 1990s, the 2500 Series quickly became a backbone solution for organizations seeking reliable and efficient networking capabilities.

One of the defining characteristics of the Cisco 2500 Series is its modular architecture, which allows businesses to customize their routers based on specific networking needs. This modularity accommodates various interface cards, enabling the integration of different protocols and connection types, including serial, Ethernet, and WAN interfaces. As a result, organizations can tailor their routers to support diverse applications while ensuring optimal performance.

The Cisco 2500 Series supports several advanced routing protocols, including RIP, OSPF, EIGRP, and BGP. This support provides flexibility for network design and ensures that users can implement scalable solutions as their business grows. Moreover, the routers come equipped with robust security features, including access control lists (ACLs) and support for VPNs, making them suitable for organizations that require a secure network environment.

A notable feature of the Cisco 2500 Series is its support for Quality of Service (QoS). This functionality allows organizations to prioritize certain types of traffic, ensuring that critical applications, such as VoIP or video conferencing, receive the necessary bandwidth and minimal latency. This is particularly beneficial for businesses that rely on real-time communications and need to maintain high levels of service quality.

Additionally, the implementation of Cisco’s internetworking technologies, such as IP and frame relay, enhances the overall performance and versatility of the 2500 Series routers. These technologies enable efficient data transmission and improve network reliability, which is essential for organizations with complex networking requirements.

In summary, the Cisco Systems 2500 Series routers are known for their modular design, support for multiple routing protocols, robust security features, and advanced QoS capabilities. Their ability to adapt to different networking environments makes them an ideal choice for businesses looking to enhance their connectivity and streamline their operations. Even decades after their introduction, the 2500 Series remains a relevant player in the networking market, demonstrating Cisco's commitment to providing effective solutions for diverse industries.
