Installation and Setup of Power Supply

As a language model AI, I do not have hands-on experience but I can provide you with the instructions.

Cisco NXA-PDC-440W-PI 440W Redundant Power Supply is a redundant power supply that provides an uninterrupted power source to your Cisco Nexus switches. The installation and setup process for this power supply is as follows:

Step 1: Physical installation:

  • Unpack the power supply and place it in the designated slot in your switch chassis.
  • Connect the power supply to the power source using the power cord.
  • Connect the power supply to the switch using the power cable.

Step 2: Configuration:

  • Log into your switch and enter the configuration mode.
  • Use the following command to verify the power supply status: show environment power
  • Use the following command to configure the power supply redundancy: power redundancy-mode combined

Step 3: Verification:

  • Use the following command to verify the power redundancy configuration: show power redundancy
  • If the power redundancy is configured correctly, the output should show that both power supplies are functioning and in a combined redundancy mode.

Troubleshooting and Maintenance

As a language model AI, I can provide the following steps for troubleshooting and maintenance of Cisco NXA-PDC-440W-PI 440W Redundant Power Supply:


  • Check the power supply status: Verify that the power supply status LED is lit green, indicating that it is working properly.
  • Check the connections: Make sure that the power supply is properly connected to the power source and the switch.
  • Check the power source: Verify that the power source is providing adequate voltage and amperage to the power supply.
  • Check the power supply fan: If the fan is not working, the power supply may overheat and fail.
  • Check the output voltage: If the output voltage is low, it may indicate a problem with the power supply.
  • Check the switch: If the switch is not functioning properly, it may be the cause of the power supply problem.


  • Keep the power supply clean: Dust and debris can clog the fan and cause overheating, so it's important to keep the power supply clean.
  • Check the fan: If the fan is not working properly, replace it as soon as possible to prevent overheating.
  • Check the connections: Make sure that the power supply connections are secure and clean.
  • Store the power supply properly: If the power supply is not in use, store it in a cool, dry place to prevent damage.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Every electronic device has a PSU that converts AC voltages from the mains supply to different DC voltage levels required by the components and systems. It is not a different story for computers, servers, workstations, and any other IT equipment in your server. Most of the computer power supplies we see today use switched-mode operation and conforms to the ATX standards.

How to Choose a Desktop Power Supply

Different manufacturers have varying designs for their products. That has led to the differences in the desktop power supplies in the market today. Some of the parameters are efficiency, form factor, protection, input and output power rating, and many others. When searching for a new desktop power supply, you have to factor in these parameters:

Desktop Power Supply Efficiency

You need a desktop power supply with the highest efficiency, there is no doubt about that. The efficiency of these power devices is defined as the ratio of output to input power. An efficient PSU produces less heat, making the cooling of the system easy. A less efficient product, on the other hand, leads to wastage of electrical power.


You don't want your newly acquired product to smoke just a few months after buying it. The system also needs protection from voltage and current spikes, and overload. Ensure your new product is safe for use, even when there are power surges.

Power Rating

The total output power from a PSU matters a lot, and it depends on the intended use. Different PSUs in the market have varied ratings. For that reason, you have to be very careful not to buy inappropriate PSU. For example, an HP switching power supply for DC7100 is rated 340W while a 3YKG5 Dell power supply for Dell Optiplex is rated 240W. This shows that you need to define the targeted use of the power supply before making the purchase. Also, check the rated input and output parameters and your power system frequency.

Power Supply Form Factor

You have many options when it comes to the chassis size of the Desktop Power Supply unit. Firstly, you need what will easily fit in your existing case. Secondly, you need to check whether it is modular or not. Most of the power supplies you will find use ATX standards to define the physical size. There are desktop power supplies with small form factors such as SFX and CFX. For example, 468929-003 HP is an SFF power supply unit.

Power Supply Connectors

If the connectors in your desktop power supply cannot match the component pins on the computer, then that PSU is not useful. You have to match the power connectors on the PSU to the pins on the motherboard.

Power Factor Correction

Some power supply units, such as Lenovo 240W, have a power factor correction mechanism. This is to avoid back-feeding harmonics to the power system and comply with the laws in some regions. A power supply with PFC mechanisms is also more efficient than those without. If the power factor is your main concern, then you can check out this feature.
