9H423-26 Module Specific Information

Operating Full Duplex 100 Mbps Fast Ethernet over two strands of multimode fiber cable.

Desired Operation Mode (Toggle)

Displays one of the following values:

Auto-Negotiation

10Base-T manual

10Base-TFD manual

100Base-TX manual

100Base-TXFD manual

100Base-FX manual

100Base-FXFD manual

Only the modes that the device is capable of using are displayed. The module defaults to auto-negotiation. If the device connected to the module also supports auto-negotiation, the devices self-configure to the fastest possible speed and duplex. For example, if the other device does not support auto-negotiation, the devices do a parallel detection and configure to either 10 Mbps or 100 Mbps, but only at half duplex. If the device connected to the module is standard Ethernet with no auto-negotiation support, and is configured for full duplex, the Desired Operation Mode field must be set to 10Base-T Full Duplex.

Advertised Ability (2 Toggles)

Allows the user to specify the advertised ability for the chosen port. The ability of each port is presented first, followed by the ability to enable/disable on each port. Advertised Ability is applicable only when the Desired Operation Mode field is set to Auto-Negotiation. Otherwise this field displays N/A and is read-only. When in auto-negotiation mode, the module auto-negotiates to the highest speed being advertised by both devices.

Port # (Modifiable)

Displays the current port for which configuration information is displayed. Use the procedure in the next section to display configuration information for a different port.
