Multiple DI-808's on the same Network - DHCP only assigns IP to (1) Device

Multiple DI-808's on the same Network - DHCP only assigns IP to (1) Device

I have two DI-808's I am trying to connect to the same network.  I set the first one up to DHCP, and it found an IP address and connected to the network.  The second one (also set to DHCP) however, does not get an IP address.  The network is far from the max number of IP addresses available.  Any ideas?
