About the Cisco PWR-2911-AC Cisco power supply / PSU
This fixed internal AC power supply delivers 150 W of continuous output power with no hot-swap capability—making it a straightforward, integrated component for Cisco 2911 Integrated Services Router (ISR G2) deployments where uptime depends on selecting genuine OEM hardware.
The PWR-2911-AC is a Cisco original equipment manufacturer (OEM) component designed specifically for the Cisco 2911 platform. It accepts wide-range input voltage of 100–240 V AC at 47–63 Hz frequency, with a maximum input current draw of 3 A at 100 V AC. Cooling is integrated with the chassis airflow through an internal fan design. The power supply connects via a proprietary internal connector matched directly to the Cisco 2911 motherboard and meets all Cisco hardware validation and safety certification requirements. This component is classified as new and is a prerequisite for Cisco TAC support contract coverage on Cisco 2911 routers, making it essential for enterprises that require vendor support and compliance verification.
Enterprise Deployment Scenarios
- Branch office routing and WAN aggregation where Cisco 2911 ISR G2 routers require OEM-validated power subsystems for uptime compliance
- Service provider edge installations demanding genuine Cisco components to maintain support eligibility and hardware warranty coverage
- Network architecture refresh projects where IT procurement teams standardize on original Cisco components across distributed router fleets
- Data center and campus backbone environments integrating Cisco 2911 platforms as part of a validated, certified infrastructure stack
- Replacement and spare-parts inventory for existing Cisco 2911 deployments requiring direct OEM compatibility with no adapter or third-party alternatives
