Procedure: Finding the status of the Ethernet connections
This procedure explains how to find the status of the Ethernet connections when
you cannot connect.
About this task
Ethernet port 1 must be connected to an active port on your Ethernet network.
Determine the state of the Ethernet LEDs by using one of the following methods:
v If the node software is active on the node, use the USB flash drive to obtain the
most comprehensive information for the node status. Go to “Procedure: Getting
node canister and system information using a USB flash drive” on page 53. The
status, speed, and MAC address are returned for each port. Information is
returned that identifies whether the node is the configuration node and whether
any node errors were reported.
v
Examine the LEDs of the Ethernet ports. For the status of the LEDs, go to
“Ethernet ports and indicators” on page 11.
Procedure
If your link is not connected, complete the following actions to check the port
status each time until it is corrected or connected.
1. Verify that each end of the cable is securely connected.
2. Verify that the port on the Ethernet switch or hub is configured correctly.
3. Connect the cable to a different port on your Ethernet network.
4.
If the status is obtained using the USB flash drive, review all the node errors
that are reported.
5. Replace the Ethernet cable.
