How to Add PoE Power Supply for Cisco 890 Series Router? Power Supply for PoE for Cisco 891FW
Although the cost-effective and popular Cisco 800 Series has been announced End-of-Life and End-of-Sale a few years ago, Cisco has never stopped updating the related services and information about the Cisco 800 Series ISR. Some users also have some typical problems while updating, or using the Cisco 800 routers. Here, in this article, we would like to share a common problem that a Cisco 891 user who named kasper123 shared. It’s about the Power supply for PoE for Cisco 891FW. What’s that? Let’s check.

This PID comes with two power supply options: 80 or 125 watts. The older CISCO890 requires the 80-watt option, whereas the newer C890 requires the 125-watt option. Why do some routers use 80 watts and others 125 watts for PoE? The 80-watt power supply is used in addition to the standard 60-watt power supply, so you will have two power supplies connected to the router. For the newer routers we combined these two power supplies into the one 125-watt power supply (hence we have a 4-pin connector). Both models support the base router as well as 4 ports with standard PoE. And if you buy the router and you've also purchased the PoE daughter card, the router will come with the PoE daughter card pre-installed. You'll also get
