Primary: Obtain an IP Address Automatically (DHCP) and AutoIP
Enabled
Secondary: no matter the setting, will never be attempted
At power-up the power supply will attempt to acquire an IP address from
a DHCP server. If it cannot find a DHCP server to assign an address, it
will assign itself a link-local address. If no other device is using that link-
local address, it will use it for 5 minutes minimum. At that time, if it is
already in communication with some other device, it will hold onto the
link-local address until the communication is finished and then retry
DHCP. If DHCP is not available, the power supply will revert to the last
successful link-local address for another 5 minutes minimum.
Primary: Obtain an IP Address Automatically (DHCP)
Secondary: Use a Static IP Address
At power-up the power supply will attempt to acquire an IP address from
a DHCP server. If it cannot find a DHCP server to assign an address, the
power supply will move to Secondary and assign itself the static IP
address. If no other device is using the IP address, the power supply
continues with that static IP address. If some other device is using the
static IP address, the power supply will move back to Primary and start
the entire operation again.
