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.
