Workstation 5 Does Not Connect to the LAN
Symptoms: The workstation is connected to the server via the LAN, but
communications can not be established.
The RJ-45 LAN connector on the rear panel includes a pair of LEDs to assist
with basic LAN connectivity troubleshooting, shown in Figure 3-10 below.
Figure 3-10: Workstation 5 LAN Indicator LEDs
The following discussion applies only to a Workstation 5 running Windows
Embedded CE 6.0.
LED1 combines both the link and connection speed functions in a single
device. When LED1 is illuminated, this indicates a valid link while the color
indicates the connection speed. The connection speed is automatically
negotiated when the cable is connected.
However, this does not mean the Workstation will actually be able to
communicate with the server. This is because the link LED operates at the
physical layer of the network, and does not require an operating system,
network drivers, or TCP/IP address to function.
As long as power is applied, the Ethernet controller in the hub or switch
produces ‘Link Beat Pulses’ that are detected by the Ethernet controller in the
WS5 causing it to illuminate the appropriate Link LED. Likewise, the Ethernet
controller in the WS5 is producing the Link Beat Pulses which are picked up
by the Ethernet Controller in the hub or switch, causing it to illuminate its Link
LED.
NOTICE
On a WS5 running WEPOS, the RJ-45 LAN Connector LEDs
currently do not function and remain dark.
