9H423-26 Module Specific Information
6
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.
