The PWR-2911-POE is a power supply for the Cisco 2911 router. It provides power to the router and its components, including the Ethernet ports that support Power over Ethernet (PoE). This allows devices connected to the router, such as IP phones and wireless access points, to receive power over the Ethernet cable, eliminating the need for a separate power source for these devices. The PWR-2911-POE is an AC power supply and is capable of providing up to 715W of power, which is sufficient to power the router and its PoE-enabled ports. This power supply is also a redundant power supply, meaning that it can provide power to the router in case of a failure of the primary power supply, helping to ensure the continuity of network operations.
Resiliency and High Availability
The PWR-2911-POE power supply for the Cisco 2911 router is designed to provide resiliency and high availability for the network operations. The redundant power supply capability allows it to provide power to the router in case of a failure of the primary power supply, helping to ensure the continuity of network operations. This means that in case of any power failure, the secondary power supply can take over the power supply to the router and its connected devices, which help to avoid any network downtime.
Additionally, the power supply has built-in over-current and over-temperature protection, which helps to prevent damage to the power supply and the router in the event of a power failure or other abnormal conditions. This makes it a reliable and secure power supply solution for Cisco 2911 router.
Furthermore, the PWR-2911-POE power supply is easy to install and maintain, with a simple, plug-and-play design that allows the power supply to be easily replaced in case of failure. This makes it easy to maintain network availability and keep it running smoothly.
Performance and Power for Digital Workplace
The PWR-2911-POE power supply for the Cisco 2911 router is designed to provide high-performance power and support for advanced features in digital workplace. The power supply is rated to provide up to 715W of power, which is sufficient to power the router and its PoE-enabled ports. This allows devices connected to the router, such as IP phones and wireless access points, to receive power over the Ethernet cable, eliminating the need for a separate power source for these devices. This makes it easy to deploy and manage devices in the digital workplace, as it reduces the need for additional power outlets and cabling.
In terms of performance, the PWR-2911-POE power supply is highly efficient, with a typical efficiency of 85% to 90% depending on the operating conditions. This means that a relatively small amount of power is lost as heat, reducing the need for cooling and helping to extend the life of the power supply. This helps to keep the power costs low, which is important for digital workplaces where multiple devices are deployed.
Furthermore, the PWR-2911-POE power supply supports advanced features such as over-current and over-temperature protection to help prevent damage to the power supply and the router in the event of a power failure or other abnormal conditions. This ensures that the network remains up and running even in case of power failures, which is crucial for digital workplaces where network availability is of the utmost importance.

All the devices in the IT system need electrical power to function. That power gets into them through a power supply, which is tasked with converting the AC mains voltage to regulated DC voltage. A router, being one of the networking devices, also requires power to function. It can have other powered devices attached to it.
Built-In Power Module
Most computers and data center equipment have built-in power supply modules. These modules have receptacles at the side of the chassis where a power cord from the main outlet is attached. The built-in router power supply needs to be very energy-efficient to reduce internal heating. Remember that any electrical power that is not converted into output is lost as heat.
Redundant Power Supply
Redundant power supply (RPS) are standalone power units used for standby power supply to a router. It requires a cable to connect it to the mains power socket outlet and a different one connecting it to the router. Usually, these RPSs have backup batteries to power the router when there is a power outage.
Since it is a backup power supply, it is designed with an intelligent monitoring system. This system sounds the alarm when the mains power disconnects, the battery runs low, and the battery is nearly dead. It also auto disconnects loads when the battery voltage drops below 11V. However, these functionalities vary from one router power supply model to the other and also depend on the capacity of the internal batteries.
Increased System Reliability
If you find an excellent router power supply, your system can be more stable. It can be even more reliable with a redundant power supply to back it up when there are power outages. The intelligent alarm system also makes it possible to act quickly when the battery is running low. Generally, a reliable power supply system will reduce downtime.
