1. HP Jetdirect LEDs (“link” LEDs)
2. Formatter “heartbeat” LED
HP Jetdirect LEDs
The embedded HP Jetdirect server has two LEDs, one for each possible link speed. When an LED is
lit, the server is functioning correctly. A link failure is indicated when both LEDs are off.
For link failures, check all of the network cable connections. In addition, you can try to manually configure
the link settings on the embedded server by using the digital sender control-panel menus.
1. Touch Administration, touch Initial Setup, touch Networking and I/O, and then touch Embedded
Jetdirect.
2. Touch Link Speed and then select the appropriate link speed.
NOTE: See Resolve network-connectivity problems on page 135 for more information about
troubleshooting HP Jetdirect and other network issues.
Formatter LED
The formatter LED indicates that the formatter is functioning correctly. While the digital sender is
initializing after you turn it on, the LED blinks rapidly, and then turns off. When the digital sender has
finished the initialization sequence, the heartbeat LED pulses on and off.
If the formatter LED is off, the formatter might have a problem. Remove the formatter cage and reseat
the memory DIMM, if one is installed. Then make sure that the formatter cage is seated correctly. If the
problem persists, replace the formatter. See
Formatter assemblies on page 49.
