Embedded LAN troubleshooting
Although networking is integrated, the embedded LAN has additional features to assist in troubleshooting. These include the following features:
●The ability to turn on and turn off the embedded networking
●An internal diagnostic to check the networking hardware
●The ability to initiate communication from the digital sender to other network devices to check communication paths
●The ability to upgrade the embedded LAN separately from the
●Procedures to upgrade the embedded LAN by installing new digital sender firmware (through the networking port)
●A Save + Restore capability for formatter exchanges
Error codes
Some embedded LAN error codes are the same as those for an EIO card. In these cases, the embedded LAN is identified as EIO 4. In other cases, because the embedded LAN is part of the digital sender firmware, the LAN error codes are within the 49.X series.
If problems exist with the embedded LAN, open the Initial Setup menu and then select the Networking and I/O menu. If the Embedded Jetdirect menu does not appear, or if the JDI is disabled or is not installed, do not look at the LEDs on the back of the digital sender next to the
LAN diagnostics
LAN diagnostics are available through the control panel (Administration, Initial Setup, Networking and I/O, Embedded Jetdirect, Diagnostics, Embedded Test). The following are available under Embedded Test:
●Loopback test
●Ping test
●Ping results
Loopback test
NOTE: The loopback test is shown as the LAN HW Test.
Perform a loopback test to check for hardware errors in the embedded LAN. The loopback test is designed to operate for a few hours, overnight, or during the weekend. When it is operating, the digital sender cannot accept network traffic such as digital send jobs.
Use the loopback test to help detect digital sender problems and embedded LAN problems that might be caused by hardware or basic firmware problems. This is done by eliminating the network as a variable in the troubleshooting process.
