Channel Switches
Full-duplex/half-duplex mode selection
switches (DIP switches #1-6) allow the
network administrator to set EACH media
converter channel, separately, either to full-
duplex or to half-duplex.
The Link Test switch (DIP switch #7)
enables or disables the Missing Link Test
feature for a block of six (6) Multichannel
Media Converter channels.
1.4
Reset Button
Located only on 100BASE-TX MFETF10xx series Multichannel Media
Converter models, the Rest button, if present, allows the network
administrator to reset ALL Multichannel Media Converter channel ports.

AC Power Supply Module/Optional Redundant
AC Power Supply Module
An AC Power Supply Module, installed at the back of the Multichannel
Media Converter before shipment, supplies power to the Multichannel
Media Converter through an external power cord connected to an external
AC outlet.
NOTE: The Multichannel Media Converter does not have an ON/OFF
power switch. Power is applied to, and removed from, the Multichannel
Media Converter by connecting and disconnecting the power cord.
The Multichannel Media Converter rear panel also contains an expansion
slot for an optional redundant Power Supply Module. When installed, the
optional redundant Power Supply Module shares the power load with the
main AC Power Supply Module. If one power supply fails, the remaining
power supply assumes the role of providing all power to the Multichannel
Media Converter, thereby protecting the Multichannel Media Converter
from a system failure.
NOTE: Both the redundant Power Supply Module and the main AC Power
Supply Module can be "hot swapped".
The MAIN power LED on the front panel of the
Multichannel Media ConverterLED is a steady amber
when thef the AC Power Supply Module is operating
properly. When the optional redundant Power Supply
Module is installed and operating properly, the BCKP
power LED is a steady green.
