To assist in solving problems with the Ethernet ports that
connect the
system to one or more Ethernet networks, use this procedure.
The management GUI provides notification and assistance in fixing many connectivity
errors. If possible, go to in the management GUI and see if there are error alerts associated with missing hardware
or Ethernet errors. For any error alerts, run the fix procedure in
the recommended order.
If the
management GUI is not accessible, use the following methods to determine if an
Ethernet link on a node canister has failed:
- If there are two canisters in the control enclosure, log into
the service assistant of the other node canister, then use the Change Node panel on the Home page
to select the canister with the failed Ethernet link. In the Node Detail, view the Ports tab
to understand each port's operational state. Refer to the Access tab to see what system addresses provide access
to management functions.
- At the rear of the node canister, examine the Ethernet status
LED for each Ethernet port, as described in Procedure: Understanding the system status LEDs.
You might also be alerted to an Ethernet link failure
by network monitoring tools on the network connected to the link,
or system functions that depend on the Ethernet link might be degraded
or offline. System functions are listed in .
The
link consists of the cable, ports and other interface hardware at
each end. All these components must be working for the link to be
working. If multiple links are offline, this might help identify which
hardware is the cause.
- If several links connected to the same switch are failing, perhaps
that switch requires maintenance.
- If both Ethernet port 1 and 2 have failed together, the node canister
might need to be replaced.
- If all links on a single host interface adapter have failed, consider replacing the host interface adapter or the canister.
If investigation does not show a clear cause of the failure,
attempt each of the following actions, until the link failure is fixed:
- Ensure that the Ethernet cable providing the link is securely
connected at both ends, and the equipment on both ends is powered
on.
- Perform Ethernet switch service procedures for a failing Ethernet
link.
- Replace the Ethernet cable with a new one of the same type.
- Replace the node canister by following
the steps in Replacing a node canister.
