TCP/IP Troubleshooting
T1
Use the following check list to troubleshoot your network communication problem.
Check Physical Media and Network Interface Cards
1. Verify that the Device is powered ON.
2. Verify that the Device and Workstation are using the correct cabling to communicate over the
network. Use category 3 UTP patch (NOT crossover) cable for 10 Base T communications, category
5 UTP patch (NOT crossover) cable for 10 Base T / 100 Base TX communications, and Token Ring
cabling for Token Ring networks.
3. Verify that the cable at both the Device and Workstation is fully plugged into the Network Interface
Card (NIC). Check the link light, which is typically a green LED, to make sure that it is lit. Typically,
but not always, a second light on the Network Interface Card will be intermittently flashing, indicating
the presence of network traffic. If neither of these lights is lit, there is a problem with the NIC.
Print a Settings List at the Device and perform these tasks:
1. Under the Ethernet Settings data label on the List, verify that your communications speed is
correctly set for your network and that you have a MAC address listed. The driver for your NIC works
at the Media Access Control (MAC) layer of the protocol stack. If no MAC address is shown, you
have either a bad NIC or no NIC at all. Replace or install the Network Interface Card.
2. Under the TCP/IP data label, determine the method being used to assign TCP/IP addressing to the
Device. Verify that the IP Address, Subnet Mask, and Gateway addresses are correct for your
network and have NOT changed from their previous settings. Note: The use of DHCP (the DHCP
Server) with a short "lease" time can cause the Device to be assigned a new IP Address when it is
powered off for an extended period of time. This will interrupt communications with workstations
using the "old" IP address. If you do not want the IP address to be subject to constant changes,
either increase the lease time at the DHCP Server, or use the Static IP Addressing method as
described in the TCP/IP Protocol Configuration procedure in the NOS selection section of this
guide.
3. Under the LPD data label, if you are communicating with the Device through an LPR port, make sure
that LPD is Enabled. If it is NOT, enable it following the instructions supplied in this guide under
TCP/IP LPD Enablement
. Also verify that the displayed port number is "515." If it is NOT, set it to
"515" using the instructions supplied in the Configure LPD procedure in the Internet Services section
of this guide.
4. Under the Port 9100 data label, to enable the Device to automatically determine the Page Description
Language to use in processing jobs sent over the workstation's LPR port, make sure that this Port is
enabled. This is the meaning of the word "raw" when used to name the queue during LPR port
creation. Follow the instructions supplied in the Configure Port 9100 (Raw Printing) procedure in
the NOS Selection section of this guide.
5. Under the CentreWare Internet Services data label, verify that this feature is Enabled. If it is NOT,
enable it following the instructions supplied in the Network Connectivity section of this guide.
