HP 310X - Manual (Page 146)

USB OK? (USB light ON solid
green?)
for HP Jetdirect 175x external print server/Internet connector for USB
and HP Jetdirect 310x external print server/Internet connector for
USB
The print server connects to its printer via a USB cable. If the USB
connection is working correctly, the USB light on the print server will
be ON solid green (bright green in color and glowing continuously,
not blinking). If the USB connection is not working correctly, the
USB light may be off, blinking green, or blinking amber.
If your print server’s USB light is ON solid green, click on the
Yes button below to return to the Troubleshooting Overview page and
continue with the next step in the troubleshooting procedure.
If your print server’s USB light is not ON solid green, or if you
are not sure what to look for, click on the No button below to start
evaluating the USB connection. Clicking the No button will also give
you information on where to find the USB light, what it looks like,
and what the correct USB cable looks like.
