Detail Information of Power Injector

The CP-PWR-INJ is a Cisco Unified IP Phone Power Injector that is used to provide power to Cisco IP phones through an Ethernet cable. It is typically used in deployments where there is no power outlet available near the phone, and power needs to be delivered over the Ethernet cable. This product is compatible with Cisco IP Phone 7940G, 7941G, 7942G, 7945G, 7962G, 7965G, 7975G, and 7971G-GE models. It provides up to 15.4 watts of power per port, which is enough to power a single IP phone. It also has a compact, lightweight design and is easy to install.

Compliant Standards

The CP-PWR-INJ Cisco Unified IP Phone Power Injector is a device that is used to provide power to Cisco Unified IP Phones. It is compliant with several industry standards, including:

  • IEEE 802.3af Power over Ethernet (PoE) - This standard defines the specifications for delivering power over Ethernet cables. This model is compliant with this standard, allowing it to provide power to the phone through the same Ethernet cable that carries data.
  • Cisco EnergyWise - This is a Cisco proprietary energy management protocol that allows devices to monitor and control energy usage. This model is compliant with this standard, allowing it to integrate with Cisco EnergyWise-enabled network devices and manage power usage.
  • UL 60950-1 - This is a safety standard set by Underwriters Laboratories (UL) for information technology equipment. this item is compliant with this standard, ensuring that it meets safety requirements for use in commercial and industrial environments.
  • FCC Part 15 Class B - This is a federal regulation that sets standards for the electromagnetic interference (EMI) emitted by electronic devices. This product is compliant with this standard, ensuring that it does not emit excessive EMI that could cause interference with other electronic devices.


The CP-PWR-INJ Cisco Unified IP Phone Power Injector is a device that is used to provide power to Cisco Unified IP phones. It is designed to be reliable and to provide consistent power to the phones, even in the event of power outages or other disruptions.

The power injector is designed to be easy to install and to be compatible with a wide range of Cisco Unified IP phones. It is also designed to be energy efficient and to use minimal power, so it is less likely to cause any disruptions to the power supply.

This item also has built-in protection against power surges, which helps to further ensure that the phones receive a consistent and reliable power supply. This means that in the event of a power surge, the power injector will automatically shut off the power to the phones to protect them from 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.

We have a wide range of accessories that can be used in almost every conceivable aspect of network design, use, and maintenance. A computer network essentially forms a telecommunication network that allows computers in the network to exchange data. Our lives are becoming more interconnected which means that it is critical to keep networks up and running to support important tasks. To create a network, you require a variety of accessories such as routers, adapters, and switches among many others that have specific roles to play within the network.

All the products are availed at affordable prices without compromising on quality to ensure that they deliver in providing network performance, versatility, and interoperability. The products are designed for use in home networks and professional networks.

On the list of networks, accessories are all types of Ethernet cables – unshielded (UTP), shielded (STP), and foil shielded (FTP). We also have standard categories of Ethernet cables including Cat5 and Cat6 to connect to the internet. Cat5 cables have four twisted pairs of copper wire and are commonly used to connect computers to LANs. Cat5 cables deliver up to 10/100 Mbps speeds at 100 MHz bandwidth. The newer Cat6 cables are quite similar – four pairs of twisted copper wires – but provide greater speeds and bandwidth capacity at up to 10Gbps and 250 Mhz respectively. Cat 6 cables are best suited for computer networks that require high data transfer speeds. The backward compatibility with Cat5 cables makes Cat6 cables ideal for your network optimized for speed and to reduce crosstalk.

KVM switches or desktop switches allow the control of several computers within a network from one or more mice, keyboards, and video monitors. Network switches with multiple ports can be used within a networking system to allow users to manually interconnect different devices on a network. We have switches that have 8 ports and more, firewalls, network intrusion detection, and even performance analysis.

Patch panels are essentially an array of ports on a single panel and provide you with an easy to manage solution for multiple wall ports. Every port on the patch panel connects via a patch cable to another port found elsewhere within the network. A patch panel bundles together multiple network ports so that they connect incoming and outgoing lines for electronics, local area networks, and electrical communication systems. As part of a LAN, a patch panel connects computers to other devices on the network or outside lines. Most patch panels have 24 ports or 48 ports but there are different sizes, even 4 port, 7 port, and 8 port panels that make replacement and maintenance easier. Lastly, the patch panel makes troubleshooting easier due to a single location for all your input jacks.

Other computer network accessories include DSP modules, USB WiFi adapters, expansion modules, video cables, wireless (WiFi) adapters, antenna, USB network adapters, wireless network adapters, fan trays, ethernet patches, and patch panels, RJ45 cables and connectors, USB to LAN, USB wireless adapter, USB converter, automatic and manual switch boxes, BNC connectors, fiber optic cables, fiber optic tools, and other computer network accessories and tools.

Additionally, we have accessories that help to make life simpler in network management. These accessories include cable management accessories such as cable ties available in different dimensions and colors and used to fasten cables/wires holding them in place safe and secure, crimp tools, cable clips also used to manage wires but differ from cable ties in that they attach to surfaces such as walls, ceiling, and floors, outlet surge protectors to protect network devices from receiving excess electricity during spikes, cutters, insertion and extraction tools, scissors, mounting brackets, pliers, network testers, and strippers among others. Every imaginable accessory and tool used to build, connect and manage a network is available here.
