I would like to order UC520-16U-4FXO-K9 for 9 users but the system comes with 8 ports integrated poe.
1-Do i need to order another 8-port Cisco Catalyst Express 520 switch or does it come with UC520-16U-4FXO-K9 ?
2-Do the UC520-16U-4FXO-K9 comes with 4 analog fxs ports ?
The WS-CE520-24TT-K9 is not a PoE switch so you may want something like the WS-CE520-24PC-K9 which does supply 24 PoE ports. The other consideration here is that the 520 Series of switches have been announced as End of Life :( There are recommended replacement switch part numbers in the attached doc;
End-of-Sale and End-of-Life Announcement for the Cisco Catalyst Express 520 Series Switches
Hope this helps!
No Idea on this. Since I am not sure I would not like to comment on this part about what I feel, becasue anything can happen :)
