PWR-2811-AC is an AC internal power supply for Cisco 2811 routers. 100-240V AC input and 47-63 Hz frequency fit standard branch circuits. The Cisco 2811 power supply runs non-PoE router configurations; inline power for Cisco EtherSwitch modules uses PWR-2811-AC-IP. The Cisco 2811 chassis has two Fast Ethernet ports, four HWIC slots, two internal PVDM slots, one NME slot and two AIM slots. The Cisco 2811, 2821 and 2851 routers use a built-in external RPS connector for redundant power, with Cisco RPS-675 as the second source. The AC unit is field-replaceable inside the chassis, so the buyer should match the 2811 label before ordering the spare form. The input power connector sits on the front panel beside the on/stand-by switch.

2A input current at 110V AC and 1A at 230V AC set the circuit check for the Cisco 2811 AC supply. 0°C to 40°C operating temperature follows the 2811 router environment, so rack temperature decides the safe operating window. PWR-2811-AC belongs in the non-PoE AC build; the AC-IP build carries 160W maximum inline power for phones through compatible EtherSwitch modules. Cisco 2800 Series safety approvals cover UL 60950, CAN/CSA C22.2 No. 60950, IEC 60950, EN 60950-1 and AS/NZS 60950. EN300386, EN55024/CISPR24 and EN50082-1 cover EMC. The 2811 accepts AC, AC-IP and DC internal power supply options, and the replacement changes the power source without changing the router chassis.
Order PWR-2811-AC as new sealed or certified refurbished for a failed Cisco 2811 AC power supply. Certified refurbished units are inspected and bench-tested in a compatible host or on a load tester; housing, latch and connector pins are inspected. Before the PO, confirm the 2811 model and AC input on the chassis label. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and returns are 30 days on every condition; terms apply. UK, EU, US and MEA stock supports RMA with advance replacement, PO accepted and Net-30 for government.

A Cisco 2811 router with the original AC supply and no inline-power requirement uses PWR-2811-AC. Match the front-panel input power connection and the chassis label before the PO. Choose certified refurbished when the router is past Cisco service and the spare is for a working branch chassis.
A Cisco 2811 router that needs a second power source uses the built-in external RPS connector with Cisco RPS-675. Keep PWR-2811-AC as the internal AC unit and order the RPS unit as the redundant source. Confirm the RPS connector cover and site power before the PO.
A mixed Cisco 2800 spares shelf needs the 2811-specific AC supply separated from 2801, 2821 and 2851 power parts. Stock PWR-2811-AC for Cisco 2811 AC routers only. Check the router model and power input on each chassis label before the PO.
Cisco 2801 routers
PWR-2811-AC fits Cisco 2811 only. Cisco 2801 routers take PWR-2801-AC= for AC replacement, and the router label must match before the PO.
Cisco 2821 or 2851 routers
PWR-2811-AC does not fit Cisco 2821 or Cisco 2851 routers. Those routers take PWR-2821-51-AC= for AC replacement.
PoE EtherSwitch modules
PWR-2811-AC is the non-PoE AC supply. Inline power on Cisco 2811 EtherSwitch HWICs needs PWR-2811-AC-IP= instead.
DC input sites
PWR-2811-AC is for AC input. Cisco 2811 DC input sites need PWR-2811-DC rather than the AC unit.

PWR-2811-AC is the Cisco 2811 AC power supply for a Cisco 2811 Integrated Services Router. The spare ordering form is PWR-2811-AC=. The unit is the non-PoE AC internal power supply, not the AC-IP inline-power version for EtherSwitch PoE builds.
PWR-2811-AC fits Cisco 2811 routers. The same Cisco 2800 family uses different power supplies on other models: Cisco 2801 uses PWR-2801-AC=, and Cisco 2821 or Cisco 2851 use PWR-2821-51-AC=. Match the chassis label before the PO.
A Cisco 2811 uses an AC, AC-IP or DC internal power supply. PWR-2811-AC is the AC non-PoE supply, PWR-2811-AC-IP is the AC inline-power supply, and PWR-2811-DC is the DC supply. Cisco RPS-675 adds an external redundant source.
PWR-2811-AC is an AC internal power supply for Cisco 2811 routers. Input is 100-240V AC at 47-63 Hz, with 2A at 110V AC and 1A at 230V AC. Operating temperature is 0°C to 40°C. Output rating, hold-up time and supply dimensions are N/A.
PWR-2811-AC is a non-PoE AC power supply. Cisco 2811 inline power for supported EtherSwitch modules uses PWR-2811-AC-IP or PWR-2811-AC-IP= instead. A non-PoE router replacement should match the original AC supply and the chassis label.
Yes, PWR-2811-AC uses 100-240V AC input and 47-63 Hz frequency. The Cisco 2811 AC input current is 2A at 110V AC and 1A at 230V AC. Provision the branch circuit for the 110V AC input current on low-voltage AC feeds.
PWR-2811-AC is the internal AC power supply, and Cisco 2811 redundancy uses the external RPS connector. Cisco RPS-675 is the second power source for Cisco 2811, Cisco 2821 and Cisco 2851 routers. Order the RPS unit separately when the site requires redundancy.
The spare PID for PWR-2811-AC is PWR-2811-AC=. The base PID identifies the installed Cisco 2811 AC power supply, and the equals form is the spare ordering form. Use the equals form for a replacement spare and match the Cisco 2811 chassis label.
PWR-2811-AC is the non-PoE AC supply, while PWR-2811-AC-IP is the AC inline-power supply for Cisco 2811 PoE builds. The AC-IP build provides 160W maximum inline power for phones through compatible EtherSwitch modules. Choose AC for non-PoE replacement and AC-IP for inline power.
PWR-2811-AC uses 100-240V AC input, while PWR-2811-DC is the Cisco 2811 DC power supply. Cisco 2811 DC input uses 24 to 60V DC. Choose the AC unit for branch AC circuits and the DC unit for DC-fed sites.
PWR-2811-AC fits Cisco 2811 routers, and the Cisco 2800 Series end-of-sale date was 1 November 2011. Cisco service for Cisco 2800 Series ended on 31 October 2016. The supply page claims no separate supply end-of-sale date.
ORM Systems offers PWR-2811-AC as new sealed or certified refurbished. New units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year. Cisco service ended on 31 October 2016, so ORM's warranty is the cover that applies. Returns are 30 days on every condition; terms apply.
