Chapter 8 Removal and Installation Procedures

Replacing a Power Supply Unit During Operations

Se n d d o c u m e n t c o m m e n t s t o n ex u s 7 k - d o c f e e d b a ck @ c i s c o . c o m

Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

To install a power supply unit while a Cisco Nexus 7000 Series device is operating, follow these steps:

Step 1 Ensure that the power switch on the power supply unit is in the standby (STBY) position and that the AC power cords are not plugged into the AC power supply.

Step 2 If the power cords are not already attached to the power supply unit, plug the power cables into the power jacks on the front of the power supply unit and tighten the cable retention devices for each cable. Depending on the amount of power consumed by the power supply unit, you need to attach one or two power cords.

Note The 6-kW power supply unit does not ship with power cables attached to it, so you must attach one or two of those cables. If necessary, you can remove the cables from the power supply unit that you removed. The 7.5-kW power supply ships with permanently attached power cables, so you do not need to attach power cables to that power supply unit.

Step 3 Grasp the power supply unit handle with one hand, and place your other hand underneath the power supply unit to support its weight. Align the back of the power supply unit with the power supply bay and slide the power supply into the power supply bay. Make sure the power supply unit is fully seated in the power supply bay and that its four captive screws are aligned with their holes in the chassis.

Note The 6-kW power supply unit weighs 22 pounds (10 kg), and the 7.5-kW power supply unit weighs 26.4 pounds (12 kg). Use two hands to safely hold and move a power supply unit.

Step 4 Screw in and tighten the four captive screws so the power supply unit is secured to the device chassis. Step 5 Plug the power cables that are already attached to the power supply unit into the AC power source.

Tip For power redundancy, plug each power cable into a separate AC power supply circuit.

Step 6 Turn the Power switch from STBY to ON.

Step 7 Verify the power supply operation by checking that the power supply LEDs are in the following states:

•Input 1 LED is green.

•If a second AC power cord was connected, the Input 2 LED is green.

•Output LED is green.

•Fault LED is not on or blinking.

If one or more of these LEDs is red, turn the power switch to standby (STBY), check the AC power connections for the line in standby (STDBY), and then turn the power switch back to ON. The LEDs for the connected power supply units should be green.

For more information on the power supply unit LED states, see Table C-5 on page C-5.

Cisco Systems 7000 series routers are pivotal in the landscape of networking, providing high-performance, reliable solutions for enterprise environments and service providers. These routers were designed to support the growing demands of digital communication, offering robust features that enhance connectivity and streamline network operations.

One of the primary characteristics of the Cisco 7000 series is its modular architecture. This allows for the integration of various interface modules and processing units, enabling organizations to customize their routers according to specific networking needs. The modularity supports scalability, as businesses can upgrade or replace components as their requirements evolve without having to replace the entire system.

The Cisco 7000 series incorporates advanced routing protocols, ensuring efficient data packet management and traffic flow. It supports multiple protocols, including OSPF, BGP, and EIGRP, facilitating seamless integration into a variety of network environments. This flexibility is essential in modern networks, where diverse communication protocols are in use.

Load balancing capabilities are another significant feature of the Cisco 7000 series. This functionality allows for the optimal distribution of network traffic across multiple paths, enhancing performance and redundancy. By ensuring that no single route is overwhelmed, organizations can maintain uptime and improve overall user experience.

Security is a top priority for many businesses, and the Cisco 7000 series addresses this need with built-in security features. It supports Virtual Private Networks (VPNs) and access control lists (ACL) to provide secure remote access and protect sensitive data from unauthorized access. This capability is vital in today’s threat landscape, where data breaches can have far-reaching consequences.

The series also boasts high throughput and low latency, making it suitable for bandwidth-intensive applications like video conferencing and cloud computing. Coupled with Quality of Service (QoS) features, the Cisco 7000 ensures that critical applications receive the bandwidth they need, thereby enhancing overall network performance.

In terms of manageability, the Cisco 7000 routers come equipped with advanced monitoring and diagnostic tools. Network administrators can easily track performance metrics and identify potential issues before they escalate, minimizing downtimes and maintaining business continuity.

In summary, the Cisco Systems 7000 series routers are a sophisticated solution for organizations seeking to optimize their networking infrastructure. With modularity, robust routing protocols, load balancing, security features, high performance, and comprehensive manageability, the Cisco 7000 series stands out as a reliable foundation for successful network operations in an increasingly connected world.
