Cautions to Take When Using in a network

Connecting a Dial-up Router to a Network

When the NetWare file server and printer are on opposite sides of a router, packets are sent back and forth, causing communication charges to be incurred. Because packet transmission is a specification of NetWare, you need to change the configuration of the router. If the network you are using does not allow you to configure the router, configure the printer instead.

Configuring the router

Filter packets so that they do not pass over the dial-up router.

❒ The MAC address of the printer doing the filtering is printed on the printer configuration page. For details about printing a configuration page, see p.128

“Printing a Configuration Page” .

❒ For details about configuring the printer if the router cannot be configured, see the instructions below.

Configuring the printer with NetWare

A

Configure the file server.

B

Set the frame type for a NetWare environment.

For details about selecting a frame type, see p.147 “Frame Type (NW)” .

Configuring the printer without NetWare

A

When not printing, the network interface board sends packets over the network. Set NetWare to “inactive”.

For details about selecting protocols, see p.147 “Active Protocol” .

Using DHCP

This printer can be used in a DHCP environment. In a WINS server environment, the printer name can simultaneously be registered with a WINS server.

Note the following points when an Ethernet interface and an IEEE 1394 (IP over

1394) interface are simultaneously installed.

Appendix

❖ When static IP addresses are set for each interface

• IP address: When set at the same value, the Ethernet interface is preferred.

• Subnet mask: When a value overlaps, the Ethernet interface is preferred.

• Gateway address: The value set is used. For the gateway address, set the gateway address located in the subnetwork set by the interface. If the value is outside the subnet range set by the interface, it operates as “0.0.0.0”.

❖ When each setting is acquired from the DHCP server

• IP address, subnet mask: Set for each value leased by the DHCP server operating on a connected interface. When overlapping IP addresses or identical IP addresses in the subnetwork are set, only the highest priority active value is set for the interface.

❒ The default priority interface is Ethernet.

• AutoNet: An automatic private address (169.254. xxx.xxx) is set for high priority interfaces.

❒ The default priority interface is IEEE 1394 (IP over 1394).

• Gateway address, DNS server address, domain name: Settings are made for DHCP-acquired values that have the highest interface priority.

If the gateway address is outside the subnetwork range set by the interface, it operates as “0.0.0.0”.

❒ The default priority interface is Ethernet.

❖ When the settings of the static IP addresses and the DHCP acquired value overlap

• IP address, subnet mask: When the static IP address and DHCP-acquired value (IP address) are the same, or the static subnet mask value and

DHCP-acquired subnet mask value overlap, the interface set by the static

IP address is available using its value set. The interface set by DHCP is reset to the default.

• Gateway address: Use the manually set value.

• If a gateway address is set outside the interface subnetwork range, it operates as “0.0.0.0”.

❒ When the static IP address is not set, or is set as “0.0.0.0”, the interface setting the DHCP-acquired value is activated.

❒ Supported DHCP server operating systems are: Windows 2000 Server, Windows NT 4.0 Server Service Pack 4 or higher, NetWare, and UNIX standard.
