If the SMS has errors and refuses to locate the device, check the connections on the device. If you use a copper-fiber translator (such as Netgear) and it is disconnected or loose, the device driver will attempt to re-initialize the port several times before timing out and placing the port in an out-of-service mode.
Netgear does not support auto-negotiation. When you remove the copper cable or the cable is loose, Netgear does not attempt to auto-negotiate with the device.

Procedure

  1. From the Ports table on the Network configuration screen, select the entry that corresponds to the Port A entry in the IPS Segments table, and then click Edit.
  2. For Auto-Negotiation, clear the Enabled check box. This disables the option.
  3. Click OK.
  4. Repeat steps 1 through 4 for port B. Leave auto-negotiation disabled. The port should reset.
