Auto-MDIX
(Internal Strap)
If Auto-Negotiation (802.3u) is enabled, the media converter determines the current cable pinout to
use on the copper interface. If Auto-Negotiation (802.3u) is disabled the Media converter will use the
RX Energy method on the copper interface to set the port MDI or MDIX whichever is appropriate.
Enabled (Default) - Either a straight-through or crossover type cable can be used to connect the
media converter to the device on the other end of the cable.
Disabled - If the partner device on the other end of the cable does not have the Auto-MDIX feature a
specific cable, either a straight-through or crossover will be required to ensure that the media
converter's transmitter and the partner devices transmitter are connected to the others receiver. The
Media converter's 100Base-TX port is configured as MDI-X with this switch setting.
PSE Power
Settable for each UTP port available.
When enabled (UP), the media converter will perform a Power Sourcing Equipment (PSE) function
as per IEEE802.3bt standard.
Default is "enabled"
PD Power Reset
This is a technique to perform a power reset on a PD device(s) attached.
When enabled ( down ), the media converter will upon loss of link on any fiber port, turn off PSE
output power to the PD device(s) for 2 seconds then turn the power back on. The power remains on
until any fiber link transitions from up to down again.
With Passthrough enabled ( Link Mode enabled and Fiber Auto-Negotiation enabled ) , a loss of link
on the fiber resulting from a loss of link on the copper, a PD Power Reset till still occur.
When PD Power Reset disabled, loss of fiber link has no effect on PSE power to the PD device(s).
