3.1.1.2. DHCP, BOOTP
ThisproductissetsothatDHCP(DynamicHostCongurationProtocol)/BOOTP(BOOTstrapProtocol)isvalidsoyoucanacquire
an IP address, sub-net mask, and default gateway from a DHCP or BOOTP server.
The default setting is DHCP, BOOTP: “enabled” A work-station running DHCP or BOOTP server over a LAN network is required
for IP address settings using DHCP, BOOTP.
The number of DHCP/BOOTP requests differs according to the DIPSW 1 settings on this product.
DIPSW1 = OFF: This is issued three times 20 seconds after the TCP/IP startup. (Factory Default Setting)
DIPSW1 = ON: Occurs unlimited times until the address is acquired.
There is a partial compatibility of the DHCP Discover protocol with BOOTP Request, so both are handled as
being the same.
Forexample,ifaBOOTPReplayisreturnedrsttotheDHCPDiscover,theBOOTPacquiredaddressisused.
The DHCP, BOOTP Request is constantly broadcast with (255.255.255.255). However, only the DHCP Renew
Request (extension request of the address usage period) is issued to the server that acquired that address.
When the address information is acquired using DHCP, BOOTP, RARP and ARP/Ping are invalidated.
The address acquired using DHCP, BOOTP is lost when the power is turned off without being written to the
non-volatile memory.
When acquiring an IP address from a DHCP server, the Subnet Mask is also acquired.
When an IP address is acquired from a BOOTP server, the following Subnet Mask is used.
[F/W Ver. 2.3.0 or older]
The Subnet Mask is calculated automatically from the IP address.
[F/W Ver. 3.0.0 or later]
-When Subnet Mask (BOOT) = HE05 Emulation: The Subnet Mask is acquired from the BOOTP server.
(Default settings)
-When Subnet Mask (BOOT) = HE07 Emulation: The Subnet Mask is calculated automatically from the IP ad
dress.
This setting can be changed by Telnet.
Settings: Register the combination of the IP address to be set, sub-net mask, default gateway and Mac address to
the DHCP/BOOTP server and then turn on the printer power.
3.1.1.3. RARP
This product can obtain the IP address from the RARP server by setting the RARP (Reverse Address Resolution Protocol) to be
valid. The default setting is RARP: “Valid”
A work-station running a RARP server over a LAN network is required for IP address settings using RARP.
When using RARP, DIPSW1 on this product must be turned OFF.
The RARP Request is issued once when 15 seconds have passed after the TCP/IP startup. However, if the IP
address is obtained by the DHCP/BOOTP within 15 seconds, the RARP request is not generated.
When the RARP address information is acquired using ARP/Ping is invalidated.
You cannot get a subnet mask or default gateway from RARP servers.
The address acquired using RARP is lost when the power is turned off without being written to the non-volatile
memory.
Settings: Register the combination of the IP and MAC addresses to be set, to the RARP server, and then turn on
the printer power.
3.1.1.4. ARP/Ping
Register the combination of the IP and MAC address of NIC to the ARP (Address Resolution Protocol) table on the PC and set the
IP address using the Ping ARP by issuing a ping.
When using RARP, DIPSW1 on this product must be turned OFF.
Operations with an IP address set by ARP/Ping are possible only when the IP address is not acquired even
with either of the methods of DHCP/BOOTP and RARP, when the Static address is not set.
You cannot acquire a sub-net mask and default gateway with ARP/Ping.
An address can be acquired using ARP/Ping only one time.
The address acquired using ARP/Ping is lost when the power is turned off without being written to the non-
volatile memory.
