HP Jetdirect LEDs
The embedded HP Jetdirect print server has two LEDs. The yellow LED indicates network activity, and
the green LED indicates the link status. A blinking yellow LED indicates network traffic. If the green LED

the link settings on the embedded print server by using the product control-panel menus.
