[c-nsp] ISR4431 integrated "POE" ports

[CiscoNSP List]

Thanks Nathan - The device has 8 ports as per the doc here:

http://www.cisco.com/c/en/us/td/docs/routers/access/4400/hardware/installation/guide4400-4300/C4400_isr/Overview.html#32890

4 of them are copper/RJ45 only (2 labelled POE, the other 2, not labelled), 4 of them SFP

gi0/0/0 -> gi0/0/3

Connecting cat5 to the 4 RJ45 ports, we certainly got links, but could def. not pass traffic....installing SFP's, and issuing media-type sfp, L3 worked immediately....so I dont know what else is required to have these other 4 RJ45 ports "work" as Eth ports...as stated, I havent had a chance to read up on them as yet, and yesterday was the first time Ive touched them.....I would have thought the ports could be used as standard eth ports without any special conf, but we certainly got links, just no L2/L3.

Cheers

Hi Mr/Mrs/Miss/Dr CiscoNSP List,

> The POE ports on these ISRs....why would Cisco label them exactly the same as the SFP/router ports?  They cant be used for routing/or anything else....only POE correct?

Why would you have a port that can do only the power part of POE?
A quick reading of the data sheet and install guide shows that the POE can be enabled as an option on ports 0 and 1. All 4 ports can be either SFP or RJ45.
Strange that your copper connections didn’t work, maybe they were to some other ports nearby - there’s an RJ45 ethernet management port called “GE0”, perhaps that was used.
