Figure D-1. NetBlazer Combo Board
The status LEDs on the combo board have the following functions:
•
A green link-integrity LED shows that a valid Ethernet link is
established between the Ethernet port and an Ethernet hub.
•
A yellow port-activity LED shows that packets are being
transferred between the Ethernet port and an Ethernet hub.
•
If no LED is lit and a workstation is connected to a hub port,
make sure that each AC power cable is working correctly, power
to the hub is turned on, power to the NetBlazer is turned on, and
the network cable is working correctly.
