They're probably discovering the other server by sending a broadcast after they fail to contact their designated server (the one that's down). You can prevent the broadcast by specifying the designated server in an AltAuth DHCP vendor option rather than in the AuthSrvr option. (More usefully, specify both AltAuth and AuthSrvr in case you ever plug in a Sun Ray whose firmware is so old that it doesn't recognise AltAuth. Firmware that recognises AltAuth will ignore AuthSrvr.) If AltAuth is present then server-discovery broadcasts are suppressed unless the AltAuth list explicitly includes the IP address 255.255.255.255. The fact that AltAuth carries a list of server IPs rather than just the single IP carried by AuthSrvr is very useful if you have a preferred *group* of servers that you want your Sun Rays to contact. It gives the Sun Rays multiple chances of contacting one of the servers that you really want it to contact. It's easier if you can move each pool Sun Rays onto their own subnets, then you don't have to hard-code their MAC addresses in DHCP. That's not always possible.
