13.Turn on the digital sender.
14.Restore the network configuration (if necessary).
If the test succeeds, the problem has not been diagnosed. If the test fails, the problem might be a
If the digital sender fails when the embedded LAN is enabled and the network cable is unplugged, disable the embedded LAN and upgrade the digital sender by installing the .RFU file.
When enabled, the embedded LAN supports the traditional methods of upgrading a Jetdirect device (FTP, HTTP, Web Jetadmin). In addition, the .RFU is upgraded when the embedded LAN is enabled or disabled.
Connectivity problems
Use the following procedure if the digital sender and the network configuration information are correct, but the network digital sender connectivity is not working.
1.Make a note of the digital sender network configuration information.
2.Touch Administration, touch Initial Setup, touch Networking and I/O, touch Embedded Jetdirect, touch Diagnostics, and then touch Embedded Test.
3.Touch LAN HW Test (the loopback test).
4.In the loopback test menu, select Yes. This begins a continuous diagnostic that is only stopped by using a power cycle. A failure is reported in an error message that appears on the control panel. (If the test fails, a hardware problem exists. If the test succeeds, go to step 5.)
5.Turn off the digital sender.
6.Turn on the digital sender.
7.Reenter the network configuration information.
8.Touch Administration, touch Initial Setup, touch Networking and I/O, touch Embedded Jetdirect, touch Diagnostics, and then touch Embedded Test.
9.Touch Ping Test.
10.Specify the destination IP address (the default is 127.0.0.1).
11.Specify the packet size (64 to 2,048, with a default of 64).
12.Specify the count (0 to 100, with a default of 4).
13.Specify the timeout (1 to 100 seconds, with a default of 1).
NOTE: Use different IP addresses to test the network connectivity. Results are obtained by opening the Ping Results menu and selecting the individual menu items.
The embedded Jetdirect and EIO cards can work together simultaneously. Or, if necessary as part of troubleshooting, the embedded Jetdirect can be disabled and an EIO card can be installed.
