Power-Supply Modules

Shutting Off Power

Even though shutting off power to the Cisco CGR 2010 router is anticipated to be infrequent, there may be occasion to turn off the router. There is no on/off switch on the Cisco CGR 2010 router. This ensures that there will not be any accidental shutdown due to inadvertently turning off a power switch; thus, guaranteeing a high reliability in keeping the router up. To shut off power to the router, there are two options:

Pull the power supply modules out of the Cisco CGR 2010 router. See “Replacing Power Supplies and Redundant Power Supplies” section on page 3-16.

The power supplies on the Cisco CGR 2010 router are hot swappable, so merely removing them from the router will remove power from the router and shut it down.

Install a disconnect device for the Cisco CGR 2010 router.

A disconnect device must be located in the proximity of the Cisco CGR 2010 router and must be readily accessible. The disconnect device must also comply with IEC 60947-1 and IEC 60947-3 or an equivalent approved disconnect device appropriate for the country of installation and be identified as the disconnect device for this equipment.

Note The maximum current rating for the power disconnect circuit breaker or overcurrent device must be 15 Amps. Operational power must be internally fused. This fuse cannot be replaced by the user. In the event of the disconnect device failing, return the unit to the factory for repair.

Replacing Power Supplies and Redundant Power Supplies

Before you perform power supply replacement, read the “Safety Warnings” section on page 5-2and disconnect power when noted.

The Cisco CGR 2010 routers have replaceable power supplies. Use a Number 2 Phillips screwdriver to remove or install the power supply.

Caution Any combination of power supplies can be inserted into the chassis. Dual power supply configurations are load sharing in redundancy mode.

A single power supply is sufficient for supporting power needs to the system. A single PSU can be deployed in either slot 1 (PSU1) or slot 2 (PSU2).

Note The power supplies are hot swappable. The power supply LED must show it is properly functioning before removing the other power supply in the router.

Replacing the Cisco CGR 2010 Router Power Supply

To replace the power supply in a Cisco CGR 2010 router, perform the following steps. See Figure 3-13for the locations of connectors and other components within the Cisco CGR 2010 router.

Step 1 Loosen the captive screws that fasten the power supply to the chassis.

Step 2 Pull the power supply out of the chassis. See Figure 3-13.

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.
