Interface physically down

The physical state of the POS interface is down.

To resolve the problem:

• Verify that the POS interface is connected correctly to the remote port.

  • The transmit connector at one end must be connected to the receive connector at the other end.

  • The transmit and receive connectors of the POS interface are not connected by the same fiber. If they are connected by the same fiber, the display interface command displays the "loopback detected" message, whether or not the loopback detection feature is enabled.

• If the two POS interfaces are directly connected, verify that the two ends use different clock mode settings.

• If the problem persists, contact Hewlett Packard Enterprise Support.
