Believe the "deadtime" tells the router how long to "ignore" a non-responsive
radius server.  The default is 0, which says always check the servers in the
order given.  With a deadtime of 1 (minute) your router should "ignore" that
server for 1 minute if it is not responsive, and then try it again (and ignore
another minute if still not responding).
