Power-Supply Modules

Connecting DC Power

Step 5 To connect DC power:

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

a.Connect the Ground wire (the green or green/yellow lead of the cable) into the terminal marked with the ground symbol. See item 7 in Figure 3-9 on page 3-12

b.Connect the Positive wire into the terminal screw labeled +.

c.Connect the Negative wire into the terminal screw labeled -.

Tip Make sure that you cannot see any wire lead. Only wire with insulation should extend from the terminal screw.

Note If you have a low-voltage DC power-supply module, connect the wires to the terminals labeled Lo. See items 5 and 6 in Figure 3-9 on page 3-12

If you have a high-voltage DC power-supply module, connect the wires to the terminals labeled Hi. See items 3 and 4 in Figure 3-9 on page 3-12

Caution Do not use a power cable to connect the chassis low-voltage DC input to a voltage source. If you inadvertently plug a cable into a 120 VAC source, the low-voltage supply will be damaged and hazard could result.

If you need a cable to connect to the low-voltage DC power supply, cut off the plug from the power cord and hard-wire the Cisco CGR 2010 low-voltage DC input directly to its power source, observing the correct polarity markings.

d.Use a tie wrap to secure the cable to the central strain relief tab next to the terminal block on the chassis. Secure the cable immediately adjacent to the terminal block to minimize strain on the cable.

The strain relief mechanism consists of three metal loops built into the chassis next to the terminal block. See Figure 3-11

Note Take care not to over-tighten the tie wrap to the loops, which could damage the wiring insulation. An over-tightened tie wrap could cause cold-flow of the wire insulation, which in turn could cause shorting of the power source to the chassis.

OL-31454-01 specifications

Cisco Systems OL-31454-01 refers to a specific configuration guide for Cisco networking equipment, which serves an essential role in helping IT professionals understand how to deploy and manage their networking hardware efficiently. This document is particularly relevant for those working with Cisco routers and switches, highlighting various features, technologies, and best practices in network management.

A core feature of Cisco Systems OL-31454-01 is its focus on enhancing network performance and reliability. The systems typically include advanced Quality of Service (QoS) mechanisms, ensuring that critical applications receive the necessary bandwidth and performance even during peak usage times. This is crucial for enterprises that rely on uninterrupted access to applications and services.

The guide also discusses technologies such as VLANs (Virtual Local Area Networks), which allow network administrators to segment networks for improved performance and security. By isolating traffic within different VLANs, organizations can mitigate congestion and enhance overall network efficiency.

Another critical aspect of OL-31454-01 is its in-depth look at security features. Cisco networking solutions typically come equipped with integrated security protocols, such as IPsec for Virtual Private Networks (VPNs) and advanced threat detection mechanisms. This layered approach to security helps protect sensitive data from unauthorized access and cyber threats.

Furthermore, the guide emphasizes the importance of automation and programmability in modern networks. Utilizing Cisco's software-defined networking (SDN) capabilities, network engineers can automate various tasks, reducing the potential for human error and freeing up valuable resources. The integration of tools like Cisco DNA Center provides a unified network management platform, enhancing visibility and control across the entire network.

In addition to these features, Cisco Systems OL-31454-01 outlines various compatibility options with existing technologies and infrastructure. The guide ensures that IT teams can seamlessly integrate new hardware into their current networks without significant overhauls, facilitating a more efficient transition.

Overall, OL-31454-01 serves as a comprehensive resource for deploying and managing Cisco systems, offering valuable insights into essential features, technologies, and best practices that can significantly enhance an organization's networking capabilities.
