1. AWG = American Wire Gauge.

Wiring the DC Power Supply

Follow the directions in this section to wire the terminal block.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied your router.)

Note This product is intended for installation in restricted access areas and is approved for use with 14 AWG copper conductors only. The installation must comply with all applicable codes.

Take the following steps to wire the terminal block:

Step 1 Attach the appropriate lugs at the wire end of the power supply cord.

Step 2 Wire the DC power supply to the terminal block, as shown in Figure 9.

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied your router.)

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.
