• 100BASE-FX - Operating 100 Mbps Fast Ethernet over two strands of
multimode fiber cable.
• 100BASE-FX Full Duplex - Operating Full Duplex 100 Mbps Fast Ethernet over
two strands of multimode fiber cable.
Desired Operational Mode (Read-Write)
Displays one of the following values:
• Auto-Negotiation
• Manual 10BASE-T
• Manual 10BASE-T Full Duplex
• Manual 100BASE-TX
• Manual 100BASE-TX Full Duplex
• Manual 100BASE-T4
• Manual 100BASE-FX
• Manual 100BASE-FX Full Duplex
Only the modes that the device is capable of 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
Operational Mode field must be set to
10Base-T Full Duplex .
Advertised Ability (Read-Write)
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 Operational 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.
If a FEPIM is not installed on the 9H422-12 Module, the Desired Operational
Mode displays N/A within brackets for that port.
