Verify that the link LED is green.
If the link LED does not light, try removing the network cable plug and reinserting it firmly into the
module socket.
Testing Connectivity: Examining Link LEDs and Counters to Verify that the
Network Traffic is Reaching the Device
If the SCE 2000 platform has been powered up, test now to verify that connectivity has been established
on all links. If the SCE 2000 platform is not powered up, perform this step after starting the SCE 2000
platform.

Examining the LEDs
The GBE Link LED must be green in order to verify that an active connection exists.
The GBE Rx and Tx LEDs (if flashing green) indicate that traffic is being received or transmitted by the
SCE 2000 platform, respectively.
Note that in an inline topology, the Rx and Tx LEDs indicate that packets are being received/transmitted
by the SCE 2000 platform.
In optical splitter topologies, the Rx LEDs are the sole indicators. The Tx LEDs do not “blink”, since
the Tx is not connected to the port in this topology.
How to View the Gigabit Ethernet Port Status
Step 1 At the SCE 2000# prompt, type show interfaceGigabitEthernet 0/ interface-number.
