The thin client unit powers on and displays
a splash screen, but does not connect to
the server.
1.
Verify that the network is operating and the network cable is working
properly.
2.
Verify that the unit is communicating with the server by having the System
Administrator ping the unit from the server:
◦
If the thin client pings back, then the signal was accepted and the unit
is working. This indicates a configuration issue.
◦
If the thin client does not ping back and the thin client does not
connect to the server, re-image the unit.
No link or activity on the network RJ-45
LEDs or the LEDs do not illuminate blinking
green after powering on the thin client unit.
(The network LEDs are located inside the
RJ-45 connector on the top, rear panel of
the thin client. Indicator lights are visible
when the connector is installed.)
1.
Verify that the network is not down.
2.
Make sure the RJ-45 cable is good by installing the RJ-45 cable onto a
known working device—if a network signal is detected then the cable is
good.
3.
Verify the power supply is good by replacing the power cable to the unit
with a known working power supply cable and testing it.
4.
If network LEDs still do not light and you know the power supply is good,
then re-image the unit.
