Both the redundant power supply and the main power supply can be “hot
swapped.” This means that should either power supply fail, the failed power
supply can be removed and replaced with a new power supply while the media
converter is operating, without network operations being interrupted.
Each power supply has its own power cord. By connecting the two power cords
to outlets on separate power circuits, you increase the protection to your
media converter from operational failure should a power circuit fail.
Note
A redundant power supply is strongly recommended for the
AT-MCF112xx Multichannel Media Converter to help avoid a
“single point of failure” to as many as twelve links.
AC Outlet
The unit does not have an ON/OFF power switch. Power is applied to and
removed from the unit by connecting and disconnecting the power cable. When
disconnecting power from the unit, you should disconnect the power cord from
the power source first before disconnecting the cord from the back panel of the
unit.
Warning
Power cord is used as a disconnection device: To de-energize
equipment, disconnect the power cord.

Reset Button
The Reset button located on the front of the converter allows you to reset the
ports on the media converter. You might need to reset the ports after
completing the media converter installation, or after adding or swapping a
power supply. You must reset after a power disruption or whenever a general
power failure status is observed.
To reset the media converter, press the Reset button on the front of the unit
for about 1 second. The LEDs on the converter will flash once, after which the
unit is ready for normal network operations.
