C. ARCNET Connector
The Power Supply Module features a red code marker
on the upper portion of the panel for easy identification
when performing system modifications or service.
An RJ-45 jack (labeled C in Figure 1-4D) is
provided to enable bay-to-bay communications via
the ARCNET protocol.

D. Primary Power Connector
The primary source of power for the MP168
Switcher enters the bay through the Primary Power
Connector (labeled D in Figure 1-4D). A mating
line cord that is tailored specifically to the national
or regional electrical requirements of the intended
installation site is provided with the module.
E. Redundant Power Connector
The Power Supply Module is capable of supporting
a redundant power supply to prevent a total loss of
power to the MP168 Switcher in instances where
problems occur with the primary power source.
The Power Supply Module provides a 10-pin port
(labeled E in Figure 1-4D) for the connection of a
redundant power supply.
F. External Sync I/O Connectors
An external AC Line synchronizer may be used
with the MP168 Switcher in cases where
synchronous line phasing is desired for the entire
system and all related components. An external
sync signal enters the MP168 Bay through the EXT
SYNC terminal (labeled F in Figure 1-4D) on the
Power Supply Module.
Note: The External Sync OUT connector is not a sync
signal generated by the MP168 Switcher; it
merely provides a looping path for an external
synchronizer routed through the Switcher.
