Assigning TCP/IP Parameters Using DHCP:
The Elite 21 printer also supports IP configuration via a Dynamic Host Configuration
Protocol (DHCP) server. DHCP is a protocol which delivers IP address configuration
information to devices on a network. A DHCP server manages a pool of available IP
addresses and grants requests for addresses from devices on the network.
DHCP is active by default on the printer. At power-up, unless a static IP address has
been assigned via the front panel, the printer broadcasts a DHCP request for an IP
address. If a DHCP server is present the request will be processed, and an IP address
will be returned to the printer. You can print a network status page, which will list the
new IP address and other IP settings (Subnet Mask, Default Gateway, etc.)
The printer does not retain the IP address permanently by default, so it will request an
address at each startup. Provided the DHCP server is properly configured and all
equipment is working correctly, the printer should be assigned the same address each
time.
The DHCP server may grant a temporary IP address, called a temporary lease or
temporary reservation, which expires after a period, or may grant a permanent or
unlimited lease or reservation which does not expire.
Devices that are granted a temporary lease will be notified before the lease expires
and asked if they would like to extend the lease. The printer will continue extending
its lease indefinitely (unless prohibited by your DHCP server configuration) and thus
maintain a consistent IP address. If the printer is not turned on or is not connected
to the network during the period when the DHCP server is sending requests to
extend the lease, however, the lease will not be extended. The DHCP server will
cancel the lease and may assign the IP address to another device.
In cases like this, you may wish to set the printer to retain the address permanently in
its NVRAM settings. This option can be accessed through Web Admin. To access this
setting, do the following:
