Support power supplies for Cisco 4431 router

[ramstyler]

I am looking for official datasheets\specifications of which power supplies are compatible for the Cisco 4431 router, which supports dual redundant power supplies. I am unable to find any official information.

For example PWR-4430-AC vs PWR-4330-AC. Are both of these supported? Any others?

We procured ISR4431 in the last 18 months with single power supply and now would like to add the additional one. Noted the End-of-Sale and End-of-Life Announcement of these routers.

Hello @ramstyler ,

The power options for the ISR 4431 are as follows:

Cisco 4431 ISR	PWR-4430-AC(=)	AC Power Supply for Cisco ISR 4430 (Default)
	PWR-4430-AC/2	Secondary AC Power Supply for Cisco ISR 4430Use PWR-4430-AC= as spare
	PWR-4430-POE-AC(=)	AC Power Supply with POE Module for Cisco ISR 4430
	PWR-4430-POE-AC/2	Secondary AC Power Supply with POE Module for Cisco ISR 4430Use PWR-4430-POE-AC= as spare
	PWR-4430-DC(=)	DC Power Supply for Cisco ISR 4430
	PWR-4430-DC/2	Redundant DC Power Supply for Cisco ISR 4430Use PWR-4430-DC= as spare

In case you need other spare components for the ISR 4K, here is a very useful link: https://blog.router-switch.com/2015/01/ordering-guide-cisco-4400-and-4300-series-routerscisco-4000-router-family/
