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.
A newly connected unknown USB
peripheral does not respond or USB
peripherals connected prior to the
newly connected USB peripheral will
not complete their device actions.
An unknown USB peripheral may be
connected and disconnected to a
running platform as long as you do
not reboot the system. If problems
occur, disconnect the unknown USB
peripheral and reboot the platform.
