If you intend to set up your client computers manually, make
Use this feature to set the controller Ethernet port configuration.
Customer doesn’t need to create a reserved space on the arrays
before the Ethernet port and HTTP service working.
3.7.6.1 DHCP Function
DHCP (Dynamic Host Configuration Protocol) is a protocol that
lets network administrators manage centrally and automate the
assignment of IP (Internet Protocol) configurations on a com-
puter network. When using the Internet’s set of protocols (TCP/
IP), in order for a computer system to communicate to another
computer system it needs a unique IP address. Without DHCP,
the IP address must be entered manually at each computer sys-
tem. DHCP lets a network administrator supervise and distribute
IP addresses from a central point. The purpose of DHCP is to
provide the automatic (dynamic) allocation of IP client configu-
rations for a specific time period (called a lease period) and to
eliminate the work necessary to administer a large IP network.
To manually configure the IP address of the controller, move the
cursor bar to the Main menu Ethernet Configuration Function
item and then press the Enter key. The Ethernet Configura-
tion menu appears on the screen. Move the cursor bar to DHCP
Function item, then press Enter key to show the DHCP setting.
Select the “Disabled’ or ‘Enabled” option to enable or disable the
DHCP function.
