125W AC adapter for 891F and 896 routers

This power adapter delivers 12V at 3.5A and 53.5V at 1.55A for a total output of 125W. It is built as a direct replacement supply for 891F and 896 series routers including the C891F-K9 model. The unit carries part number 341-0502-01 and is supplied in new condition.

Dual-voltage headroom for PoE and system loads

The 12V rail powers the main router board while the 53.5V rail provides headroom for Power over Ethernet ports on supported 891F and 896 units. It runs out when total draw exceeds 125W or when a device requires a different voltage pair or connector pinout not matched by this adapter.

Questions about this item

Will the PA-2121-1-LF power my existing Cisco 891F or 896 router without modification?

The adapter is listed for the 891F and 896 series, including the C891F-K9, so it matches the voltage and current those routers expect.

How can I confirm the adapter is delivering the rated 12 V at 3.5 A and 53.5 V at 1.55 A after I connect it?

Measure the DC output with a multimeter under load; you should see approximately 12 V on the primary rail and 53.5 V on the secondary rail when the router is powered on.
