Procedure: Finding the status of the Ethernet connections

This procedure explains how to find the status of the Ethernet connections when
you cannot connect.
Ensure that the software is active on the node before you begin this procedure. Go
to "Procedure: Understanding the system status using the LEDs" on page 198.
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 Use the USB key to obtain the most comprehensive information for the node
status. Go to "Procedure: Getting node canister and system information using a
USB key" on page 198.
The status, speed, and MAC address are returned for each port. Information is
returned that identifies whether the node is the configuration node and if 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 .
The activity LED flashes when there is activity on the connection. The link state
LED must be permanently on. If it is off, the link is not connected.
If your link is not connected, perform 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 key, review all the node errors that are
reported.
5. Replace the Ethernet cable.
6. For the 10 Gbps Ethernet port, replace the small form-factor pluggable (SFP)
transceiver. See "Replacing an SFP transceiver" on page 212.
7. Follow the hardware replacement procedure for a node canister. See "Replacing
a node canister" on page 209.
