Cisco PWR-2911-DC-POE
Cisco 2911 DC Power Supply with Power over Ethernet
Product Highlights
What's Included
Deploying a Cisco 2911 Integrated Services Router in a DC-powered environment — such as a telecom central office, mobile network site, or industrial facility — demands a power supply that matches the infrastructure. The Cisco PWR-2911-DC-POE is an internal DC power supply with Power over Ethernet (PoE) capability, purpose-built for the Cisco 2911 ISR.
This power supply accepts a 24–60 VDC autoranging input with support for both positive and negative polarity, making it suitable for a wide range of DC plant configurations. Its integrated PoE functionality enables the Cisco 2911 to deliver power to connected PoE-enabled devices such as IP phones, wireless access points, and IP cameras — eliminating the need for separate power sourcing equipment at the branch.
The PWR-2911-DC-POE shares the same modular, field-replaceable form factor as all other Cisco 2911 power supply options, allowing straightforward installation and replacement with minimal tools. Whether you are refreshing an existing DC-powered 2911 deployment or building out a new branch site on DC infrastructure, this power supply delivers the reliability and PoE capability your network endpoints require.
Features & Benefits
DC Power Input with Autoranging Flexibility
The PWR-2911-DC-POE accepts 24–60 VDC input and supports both positive and negative polarity configurations. This autoranging capability ensures compatibility with diverse DC plant standards found in telecom central offices, remote cell sites, and industrial environments — no external converters required.
Integrated Power over Ethernet (PoE)
With built-in PoE support, the Cisco 2911 can power connected endpoint devices such as Cisco IP phones, wireless access points, and surveillance cameras directly through Ethernet cabling. This consolidates power delivery at the branch, reducing cabling complexity and the need for dedicated AC outlets at each endpoint.
Modular, Field-Replaceable Design
All Cisco 2911 power supply options share the same modular form factor for easy removal and replacement. The PWR-2911-DC-POE slides into the chassis and secures with captive screws, enabling fast swaps during planned maintenance windows without specialized tools.
Purpose-Built for Cisco 2911 ISR
Engineered specifically for the Cisco 2911 Integrated Services Router, this power supply integrates seamlessly into the chassis. It supports the full range of Cisco 2911 services — routing, voice, security, and data — ensuring the platform operates at its designed performance level in DC-powered deployments.
Deployment Scenarios
Telecom Central Office / CO Deployment
Central offices typically run on -48 VDC plant power. The PWR-2911-DC-POE's 24–60 VDC autoranging input with negative polarity support makes it ideal for powering a Cisco 2911 ISR in these environments while simultaneously delivering PoE to co-located IP phones or access points.
Remote or Cell-Site Branch Router
Mobile network and remote sites often rely on DC battery backup systems. This power supply allows the Cisco 2911 to operate directly from the site's DC bus, providing PoE to connected endpoints without requiring AC power conversion equipment.
Industrial or Utility Network Edge
Industrial facilities and utility substations frequently use DC power distribution. The PWR-2911-DC-POE enables deployment of a Cisco 2911 router with PoE-powered IP cameras or sensors at the network edge, simplifying infrastructure in environments where AC power may be unavailable or impractical.
Spare / Replacement Power Supply
For organizations with existing Cisco 2911 DC-PoE deployments, keeping a spare PWR-2911-DC-POE on hand ensures rapid recovery from a power supply failure. The modular form factor allows field replacement without specialized training.
