Do you at least know what type of switch you're connecting to? See if you
can find out and ask whoever manages them if Spanning Tree and/or Port Fast is
enabled on the port you are using for your server.

Correct. anaconda uses pump, and once the system setup is done, ISC's
dhclient is used. I wish dhclient was used by anaconda. :)

than 60 seconds.. but I have gone higher when testing.

If it's not a switch problem, hopefully someone else can give you some
assistance then. :) Easy to eliminate the switch as an issue though (by
sticking a dumb hub or something between your server and your switch), so may
as well try it.
