Troubleshooting NOTE: During Power Up, the printer performs an interface hardware test. The presence of the Ethernet Interface menu selections at the printer operator panel indicates that the Ethernet Interface hardware is functioning properly. See the IBM 6400 Line Matrix Printer Setup Guide (S544-5640) for configuration menu information. Check the IP information on both the Ethernet Interface and OS/2 station for correctness. Make sure the value in step 8 is actually defined on the Ethernet Interface. See the Configuration Tools section on page 1-7 to determine how to verify this. Verify also that you are spelling the printer name correctly. Verify that LPRPORTD is running. TCP/IP Access Problem If you can "ping" the printer from a workstation, but you cannot Web browse, Telnet, or print to the printer through the Ethernet Interface, there may be an incorrect entry in the TCP access list. In order for this workstation to use the Ethernet interface in this case, one of two things must happen. 1. The TCP list must have an entry added to grant access to this workstation. 2. All entries must be deleted from the TCP list to grant all workstations/hosts access to the above TCP services. To view the current access list: Use the printer operator panel to access the menu. See the IBM 6400 Line Matrix Printer Setup Guide (S544-5640) for configuration menu information. From the Operator Print Test menu choose the Ethernet Test Page. When the page prints, look under the "TCP ACCESS TABLE" section for the TCP access list entries. To add/delete a TCP access list entry, refer to TCP Access Lists information on page 8-3. NOTE: When the following procedure is used, the TCP access list will be cleared but all IP addresses will need to be entered again after the procedure is complete. OS/2 Configuration 2-7

OS/2 Configuration
Troubleshooting
NOTE:
During Power Up, the printer performs an interface hardware test.
The presence of the Ethernet Interface menu selections at the
printer operator panel indicates that the Ethernet Interface
hardware is functioning properly. See the
IBM 6400 Line Matrix
Printer Setup Guide
(S544–5640) for configuration menu
information.
Check the IP information on both the Ethernet Interface and OS/2 station for
correctness.
Make sure the value in step 8 is actually defined on the Ethernet Interface. See
the Configuration Tools section on page 1–7 to determine how to verify this.
Verify also that you are spelling the printer name correctly.
Verify that LPRPORTD is running.
TCP/IP Access Problem
If you can “
ping
” the printer from a workstation, but you cannot Web browse,
Telnet, or print to the printer through the Ethernet Interface, there may be an
incorrect entry in the TCP access list. In order for this workstation to use the
Ethernet interface in this case, one of two things must happen.
1.
The TCP list must have an entry added to grant access to this workstation.
2.
All entries must be deleted from the TCP list to grant all workstations/hosts
access to the above TCP services.
To view the current access list:
Use the printer operator panel to access the menu. See the
IBM 6400 Line Matrix
Printer Setup Guide
(S544–5640) for configuration menu information. From the
Operator Print Test menu choose the Ethernet Test Page. When the page prints,
look under the “TCP ACCESS TABLE” section for the TCP access list entries.
To add/delete a TCP access list entry, refer to TCP Access Lists information on
page 8–3.
NOTE:
When the following procedure is used, the TCP access list will be
cleared but all IP addresses will need to be entered again after the
procedure is complete.
