For this configuration you have to consider a couple of things:
If HMC1 with the DHCP server fails, the CEC and the HMC will work properly
as long they have their IP-addresses.
If HMC2 has to be rebooted and HMC1 is still down, HMC2 has to be
configured as a DHCP server. Note that only one DHCP server is allowed in
one network. So in this unlikely case, when you want to start HMC1 again, it
has to be configured as a DHCP client.
If you want to avoid such problems, you can use fixed IP-addresses.
