HP Jetdirect 175x Print Server series - Manual (Page 83)

USB light OFF
for HP Jetdirect 175x external print server/Internet connector for USB
and HP Jetdirect 310x external print server/Internet connector for USB
If the USB light is OFF, it means that the print server’s USB connection is not operational. This is OK
before the print server finishes starting up (whether or not a USB cable is attached). If the light remains
OFF after startup, then the print server may be faulty.
Please restart the print server by detaching the power cable and re-attaching it. Wait for the
power/status light to stop blinking (when the self-test finishes).
Is the USB light now ON solid green?
If yes, click on the Yes button to return to the Troubleshooting Overview page and continue with the next
step of the troubleshooting procedure.
If no, your print server has a problem that requires assistance from HP Jetdirect technical support; click
on the No button for information on contacting HP.
