●
Power connector
●
Keyboard

The thin client unit does not power on.
1
. Verify that the power supply is good by installing it on a known working unit
and testing it. If the power supply does not work on the test unit, replace the
power supply.
2
. If the unit does not work properly with the replaced power supply, have the
unit serviced.
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, reimage 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 LED's still do not light and you know the power supply is good, then
reimage the unit.
5
. If network LED’s still do not light, run the IP configuration procedure on page
4-23.
6
. If network LED’s still do not light, have the unit serviced.
