Installation
This completes the unshielded twisted pair Ethernet installation. Proceed to
the
Verifying Successful
Installation
section.
Verifying Successful Installation
You are now ready to apply power to the Serial Server. Plug the power
supply into the wall, connect it to the Serial Server, and then turn on the
printer. The Serial Server will go through the following startup sequence:
1. It will run through a set of power-up diagnostics for a few seconds. If
the Serial Server is operating properly, the yellow TEST LED will
blink momentarily and then go out. If the TEST LED blinks
continuously in a regular pattern, there is a problem. If this is the case,
first verify that you have a good Ethernet connection and then try
powering the unit off and then on again. If the problem persists, refer
to the
Troubleshooting
chapter in the Administrator’s Guide on the
CD-ROM included with the Serial Server.
2. When the test LED goes out, the green LED on the Serial Server will
come on solid if there is a good 10baseT Ethernet connection. If this
LED does not come on, double check your cabling and make sure that
you have a good Ethernet hub.
Verifying the Connection to the Device
Before attempting to print, it is
very
important to verify the connection
between the Serial Server and the device.
If this connection is not good you
will not be able to communicate!
To verify this connection with a serial printer or other device that can
display ASCII characters, make sure that both the Serial Server and the
printer are powered on and ready. Then print a test page as follows:
•
Push the Test/Factory button in briefly (more than one-eighth second
but less than five seconds). If the connection is good, a test page will be
printed on the printer. If nothing prints out, make sure that the cable or
I/O connection is good and that it is securely fastened.
If you are connecting the Serial Server to a non-printing device that cannot
display ASCII characters, then it is a good idea to try temporarily
connecting a printer to the serial port as described in the previous paragraph
in order to verify the connection.
