Use the LEDs to monitor the status of the media converter.
LED states are as follows:
Fiber-Link/Act LED
Green
ON = Link (fiber)
Flashing = Activity
TP-Link/Act LED
Green
ON = Link (copper)
Flashing = Activity
Power LED
Green
ON = Connected to power

Product features
Congestion reduction
The M/GE-PSW-xX-01 media converters do not forward collision signals or error
packets from one collision domain to another, resulting in improvements in
baseline network performance. In addition, the media converter filters packets
destined for local devices, which reduces network congestion also.
Auto-Negotiation
The Auto-Negotiation feature is ON permanently for the M/GE-PSW-xX-01 media
converters. Auto-Negotiation allows the media converter to configure itself
automatically to achieve the best possible mode of operation over a link. It
broadcasts speed (10 /100/1000 Mb/s) and duplex capabilities (full or half) to the
other device and negotiates the best mode of operation. Auto-Negotiation allows
quick and easy installation because the optimal link is established automatically.
In a scenario where an auto-negotiation device is linked to a non-negotiating device,
the negotiating device via parallel detection recognizes the speed of that second
device then establishes the best operating speed (10/100/100Mbs) at half-duplex.
AutoCross™
The AutoCross feature allows using either straight-through (MDI) or crossover
(MDI-X) copper cables when connecting to 10Base-T or 100Base-TX devices.
AutoCross determines the characteristics of the connection and automatically
configures the device to link up, regardless of the copper cable configuration, MDI
or MDI-X.
Link Pass-Through
The Link Pass-Through feature (illustrated below) allows the media converter to
monitor both the fiber and copper RX (receive) ports for loss of signal. In the event
of an RX signal loss (1), the media converter will automatically disable the TX
(transmit) signal (2), thus “passing through” the link loss (3). The far-end device is
automatically notified of the link loss (4), which prevents the loss of valuable data
unknowingly transmitted over an invalid link.
Note: Both copper and fiber cables must be installed before the LEDs will light.
