The MicroMMAC-T Chassis View

Figure 2-11. The Ring Port Status Window

Ring Port Status Window Fields

The window contains the following fields:

Board Number

The HubSTACK Interconnect Bus port number on the MicroMMAC-T occupied by the module containing the selected ring port.

Port

Displays the port index number and type (Ring In/Ring Out) of the selected ring port.

Last Wire Fault

This field displays either the last date and time the MicroMMAC-T was reset, or the date and time that a wire fault on the selected port last occurred.

Media Type

This field allows you to select the media type of the ring port. This field does not apply to the MicroMMAC-T, and is therefore grayed-out.

Phantom Current

This field allows you to activate or deactivate phantom current for the selected ring port. Devices that support this feature — called the autowrap feature — use a phantom current to act as a carrier sense between two connected ring ports. If the carrier sense is broken (i.e., the wire is broken) the phantom current is lost and the ports automatically wrap to maintain the continuity of the ring.
