2 - Speed
Up - Forces 100 Mb/s on the copper port.
Down - Forces 10 Mb/s on the copper port.
(Only when Auto-Negotiation is disabled)
3 - TP Full/Half Duplex
Up - Full-Duplex the twisted-pair cable distances
are constrained by the cable requirements.
Down - Half-Duplex the twisted-pair cable
distances are constrained by the 512-Bit Rule.
(Only when Auto-Negotiation is disabled)
4 - Fiber Full/Half Duplex
Up - The cable distances for the fiber port are
constrained by the cable requirements.
Down - The cable distances for the fiber port are
constrained by the 512-Bit Rule.
5 - AutoCross™
Up - Enables the AutoCross function.
Down - Disables the AutoCross function.
The AutoCross™ feature allows either straight-
through (MDI) or crossover (MDI-X) cables to be
used when connecting to 100Base-TX devices,
such as wireless access point, VoIP phone,
network camera, etc. AutoCross determines the
characteristics of the cable connection and
automatically configures the unit to link up,
regardless of the cable configuration.

6 - PSE Power
Up - Enables PSE power.
Down - Disables PSE power.
The IEEE 802.3af™ standard allows a device to
provide power (PSE - Power Sourcing Equipment)
to a remote device and for a remote device (PD -
Powered Device) to accept and use this power
over a twisted pair interface.
7 - PSE/LPT
Up - Disabled PSE/LPT.
Down - Enabled PSE/LPT.
This feature is used to re-initialize a powered device
(PD). If the fiber RX (receive) link drops with the
PSE/LTP switch in the enable position (down), the PSE
power will turn OFF for two seconds then turn back
ON to re-start the remote device. The power will
remain ON to allow the remote PD to re-establish the
link with the media converter.
8 - Not Used

Additional features

Link Pass-Through (always enabled)
The Link Pass-Through allows the media converter to monitor both the fiber
and copper RX (receive) ports for loss of signal. In the event of a loss of an RX
signal on one media port, the media converter will automatically disable the
TX (transmit) signal of the other media port, thus, "passing through" the link
loss.
The far-end device is automatically notified of the link loss, which prevents
the loss of valuable data unknowingly transmitted over an invalid link. See
diagram below.
