5 - Signal Pairs / Spare Pairs
up
- Selects MDI PSE signal pairs.
down
- Selects MDI PSE spare pairs.
NOTE:
When switches 1-5 are all set to “up”, the
SFEPE10xx-1xx is in IEEE802.3™ mode and normal
polarity power is inserted on the signal pairs.

7 - Pause
up
- Enables the Pause feature.
down
- Disables the Pause feature.
The Pause feature improves network performance
by allowing one end of the link to signal the other
to discontinue frame transmission to relieve buffer
congestion.
Enable the Pause feature only if it is present on ALL
network devices.

6 - Auto-Negotiation
up
- Enables Auto-Negotiation.
down
- Disables Auto-Negotiation.
The Auto-Negotiation feature allows the media
converter to bring up the copper links to the highest
speed and mode possible for all the attached
network devices.
NOTE
: The SFEPE10xx-1xx does NOT support rate
conversion between 10Mb/s and 100Mb/s network
devices.

4 - Voltage Polarity
up (normal)
- Selects positive (+) voltage on pairs 4
& 5 and 1 & 2 for both signal pairs and spare pairs
(see switch 5).
down (reverse)
- Selects positive (+) voltage on
pairs 7 & 8 and 3 & 6 for both signal pairs and
spare pairs (see switch 5).
NOTE:
The PD Signature

up
- Enables the AutoCross function.

- 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.

up
- Enables Link Pass-Through.
down
- Disables Link Pass-Through.
The Link Pass-Through feature 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.

9 - Far End Fault
up
- Enables Far End Fault.
down
- Disables Far End Fault.
When the Far-End Fault feature is activated, a
fault on an incoming fiber link causes the media
converter to transmit a Far-End Fault signal on
the outgoing fiber link. In addition the Far-End
Fault signal also activates the Link Pass-Through,
which, in turn, disables the link on the copper
portion of the network.
