PWR-2911-AC is a 220W AC internal power supply module for Cisco 2911 routers and supports hot-swap service when an RPS or PoE boost source is installed. The Cisco 2911 power supply slot accepts AC, PoE, and DC families, but this unit is the non-PoE AC option. Cisco 2911 routers use external Cisco Redundant Power System 2300 redundancy through an RPS adapter, not a second internal AC module. A Cisco 2911 with endpoint PoE needs PWR-2911-POE instead. Cisco stopped selling this module on December 9, 2017, and Cisco service ended on December 31, 2022. Before the PO, confirm the router model and the AC power-supply label on the chassis. Use 100-240V AC circuits.

220W maximum AC power consumption fits the Cisco 2911 router power envelope and sets the branch circuit capacity for a populated chassis. 100-240V AC autoranging input and 47-63 Hz frequency let the module run on 100V through 240V AC feeds. 2.3A to 0.35A input current is configuration dependent, so size the circuit for the 100V end of the range. 30A surge current at 115V AC and 60A at 230V AC set the inrush allowance for the AC feed. PWR-2911-AC reaches 751 BTU/hr at the maximum AC power draw. Normal operation is 0°C to 40°C for the Cisco 2911 model. The power supply slides out after the two captive screws are loosened, and the blank panel belongs on an empty supply slot. Keep airflow covers in place.
PWR-2911-AC is sold new sealed or certified refurbished. Certified refurbished units are inspected and bench-tested in a compatible host or on a load tester; housing, latch, connector pins, power-on state, rated-voltage output, and normal status LEDs are verified. Order new sealed for unopened spare pools or certified refurbished for post-support replacement. New units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year. Returns are 30 days on every condition, terms apply. Regional stock and RMA with advance replacement cover UK, EU, US, and MEA sites; PO accepted and Net-30 for government.

Your Cisco 2911 fleet is past Cisco service after December 31, 2022, and failed power supplies still need like-for-like spares. Keep the internal AC module matched to the chassis label, choose new sealed for shelf spares or certified refurbished for controlled replacement, and specify the 100-240V AC feed before the PO.
A Cisco 2911 router with AC OK off or a failed internal supply needs the AC module matched to the installed power family. Replace a failed non-PoE AC unit with this unit, keep the blank panel ready for an open bay, and confirm the router is not a 2901, 2921, or 2951.
Your Cisco 2911 needs power redundancy without changing the main AC power module. The chassis uses an external Cisco Redundant Power System 2300 through RPS-ADPTR-2911, and hot-swap service requires RPS or PoE boost power in place. Confirm the adapter slot and redundant power connection before the PO.
Cisco 2901 routers
PWR-2911-AC does not fit Cisco 2901 routers; Cisco 2901 takes PWR-2901-AC for a non-PoE AC replacement in the 2900 Series family.
Cisco 2921 or 2951 routers
PWR-2911-AC does not fit Cisco 2921 or Cisco 2951 routers; those chassis take PWR-2921-51-AC for non-PoE AC service in the same generation.
Endpoint PoE power
PWR-2911-AC does not provide endpoint PoE power; Cisco 2911 endpoint PoE on AC needs PWR-2911-POE for the internal PoE supply.
DC power sites
PWR-2911-AC is an AC-input module; Cisco 2911 DC power sites need PWR-2911-DC for a non-PoE DC replacement in the router.

PWR-2911-AC is the Cisco 2911 AC Power Supply for Cisco 2911 routers. The unit is the non-PoE AC power supply option in the Cisco 2911 power family. The spare form is PWR-2911-AC=, and the base ordering form also served system and spare orders.
PWR-2911-AC fits Cisco 2911 routers. Cisco 2901 routers take PWR-2901-AC, and Cisco 2921 or Cisco 2951 routers take PWR-2921-51-AC for non-PoE AC replacement. Before the PO, confirm the router model and the power-supply label on the failed unit.
A Cisco 2911 uses PWR-2911-AC for non-PoE AC power, PWR-2911-POE for AC power with endpoint PoE, PWR-2911-DC for non-PoE DC power, and PWR-2911-DC-POE for DC power with PoE. External redundancy uses Cisco Redundant Power System 2300 through RPS-ADPTR-2911.
PWR-2911-AC supports 220W maximum AC power consumption on the Cisco 2911 router, with 100-240V AC autoranging input and 47-63 Hz frequency. Input current is 2.3A to 0.35A, and maximum AC power reaches 751 BTU/hr. Surge current is 30A at 115V AC and 60A at 230V AC.
Yes, PWR-2911-AC is hot-swappable in a Cisco 2911 when RPS or PoE boost power is installed. The Cisco 2911 uses external Cisco Redundant Power System 2300 redundancy through an RPS adapter. The internal AC module is not a second internal redundant supply bay.
No, PWR-2911-AC is a Non-PoE AC power supply for Cisco 2911 routers. A Cisco 2911 that needs endpoint PoE from an AC supply uses PWR-2911-POE, which provides 200W of internal endpoint PoE. External PoE boost on a Cisco 2911 reaches 750W.
PWR-2911-AC requires a country-specific AC power-supply cable during Cisco 2911 configuration. The input range is 100-240V AC at 47-63 Hz, and the AC feed must match the site circuit. Use the cord family selected for the router country, not a DC terminal block or PoE-only build.
PWR-2911-AC stays in the internal AC power position while the Cisco 2911 uses external redundancy. The redundant power source is Cisco Redundant Power System 2300, and the router needs RPS-ADPTR-2911 for the connection. Hot-swap service applies when the redundant or boost source is installed.
PWR-2911-AC is the non-PoE AC supply, and PWR-2911-POE is the AC supply with Power Over Ethernet for Cisco 2911 routers. Choose PWR-2911-AC for a like-for-like non-PoE AC replacement. Choose PWR-2911-POE when service modules need endpoint PoE power from the router.
PWR-2911-AC is the AC-input non-PoE supply, and PWR-2911-DC is the DC-input non-PoE supply for Cisco 2911 routers. PWR-2911-AC fits 100-240V AC circuits. PWR-2911-DC fits DC power sites that need the Cisco 2911 DC supply instead.
Cisco stopped selling PWR-2911-AC on December 9, 2017. Cisco service ended on December 31, 2022. PWR-2911-AC and PWR-2911-AC= have no replacement product.
ORM offers PWR-2911-AC new sealed or certified refurbished. New units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year; returns are 30 days on every condition, terms apply. Cisco service ended on December 31, 2022, so ORM's warranty is the cover that applies.
