  DHCP is *advisory*.  The clients that do DHCP could just as well
configure a static IP, and get network access.

  Sniff the local net.  Find an unused IP.  Configure it.

  Configuring static IP's is impossible only if the switch filters
traffic.  i.e. It blocks all network traffic except for DHCP, until the
DHCP IP has been allocated.  Once the IP has been allocated, it only
permits traffic that uses that source IP.

  This is not, as yet, a common configuration for a switch.
