Setting the two-position DIP switch
A two-position DIP switch
(located on the back of the media converter)
supports
selecting Auto-Negotiation and Full- or Half-Duplex. Typically, most installation
will work with both switches in the UP position. Use a small, flat-blade screwdriver
(or a similar device)
to set the switches according to the site requirements; see the
illustration and explanation below.
A
uto-Negotiation:
UP
Enable Auto-Negotiation
DOWN
Disable Auto-Negotiation
Full/Half Duplex
(functions only when Auto-Negotiation is enabled.)
UP
Full Duplex -- Advertises 100 Mb/s full-duplex only during Auto-
Negotiation.
DOWN
Half Duplex -- Used primarily when connecting to a hub. Operates at
100 Mb/s in duplex mode of the attached device.
Note:
The configuration of the DIP switches should match that of the RJ-45 port
configuration of the connecting device
Full/Half Duplex - UP=Full
Auto-Negotiation - UP=Enable

Powering the media converter
DC power adapter:
1.
Insert the power adapter barrel into the barrel connector located on the back of
the media converter, shown above.
2.
Connect the power adapter plug into AC power.
3.
Observe that the power ON LED is lit.
USB port power:
Use a USB 2.0 Type A to B male-to-male cable to enable powering the media
converter via an active USB port.
Note:
When using the USB port to power the media converter, make sure that the
output USB port is turned ON
(some laptops and PCs can turn OFF the
USB port)
.
The media converter can also be powered via the USB port. When powering the
media converter with the power adapter and through the USB power, the media
converter has redundant power (
no load balancing which means the device draws
operating current from higher voltage source, adapter or USB)
. If the power
adapter is removed, the media converter will be powered via the active USB port.
Note:
The USB port provides power to the device only; it is not used to transfer
data.
