2. If the printer does not have an IP address already
assigned, use the arp command to set a temporary IP
address.
Example: for IP address 192.68.20.127 and network card
address 00:80:87:01:00:D2
# arp –s 192.168.20.127 00:80:87:01:00:D2
temp
The Ethernet address (MAC address) 00:80:87:01:00:D2
in the above example can be determined from the network
card self-diagnostic test.
3. Use the ping command to confirm the connection with the
network interface card.
Example: for IP address 192.168.20.127
# ping 192.168.20.127
If there is no reply, there is a problem with the
configuration of the IP address (the IP address has already
been set manually or dynamically), or with the network.
Reset the network interface card settings to default and try
to set a temporary IP address.
If you still have the problem after resetting the network
interface card, consult the network manager.
4. Login to the network interface card using TELNET.
Example: Logging in to IP address 192.168.20.127
#telnet 192.168.20.127
Trying 192.168.20.127
Connected to 192.168.20.127
