(C891FW-A-K9)
In order to add PoE to an 891 router, the datasheet says you need “800-IL-PM-4 with 125W PSU.” I had to use the Cisco Commerce Workspace to generate a config starting with the 800-IL-PM-4= part number and then added the 125W power supply there. The following is what was shipped:
The 800-IL-PM-4= part is a daughter-card that is installed onto the motherboard of the 891 router.
The 125W power supply had the Cisco part number of PWR-125W-AC. The power supply is a LiteOn unit, model PA-2121-1-LF or 341-0502-01 (both were listed) putting out 12V, 3.5A of DC power on one rail and 53.5V, 1.55A on the other.
Lastly, there were three baggies with hardware.
50-1807-02-A0 – 2 standoffs with two notches
50-1700-01-A0 – standoff with one notch
48-0421-01-A0 – 3 screws
Hello, do this power supply succeed to supply the PoE ports since its output power is not 125 Watts?
Yes, the power supply worked fine for providing PoE. By the way, the power supply is indeed 125 Watts.
(12V * 3.5A) + (53.5V * 1.55A) = 124.925W
Hey Brian, appreciate this little snip! Helped me figure out the power adapter part#. (PWR-125W-AC) The datasheets aren’t helping as much as before 😉
needed the info to correlate 341-0502-01 to 125W
