Troubleshooting
Basic Troubleshooting
If the thin client is experiencing operating problems or will not power on, review the following items.
Table 4-6 Power-On Troubleshooting
Issue Procedures
The thin client unit is experiencing operating
problems. Ensure that the following connectors are securely plugged into the thin client unit:
●
Power connector
● Keyboard
●
Mouse
● Network RJ-45 connector
●
Monitor
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, 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.
5. If network LEDs still do not light, run the IP configuration procedure.
6. If network LEDs still do not light, have the unit serviced.
