5. If the multiplexer is equipped with a redundant power supply, connect the redundant input
power source to the input power terminal block on the rear of the Shelf as follows:
Ac-Powered Multiplexers:
Redundant Ac Input (hot) +BAT R terminal
Redundant Ac Input (neutral) -BAT R terminal
Dc-Powered Multiplexers:
Redundant Station Battery + +BAT R terminal
Redundant Station Battery - -BAT R terminal
For dc-powered multiplexers, make sure that a 2-amp slow-blow fuse is placed in
line with Redundant Station Battery + to protect the multiplexer.
6. Connect the T1 inputs and outputs of each M-DACS by connecting the cable containing the
appropriate T1 input and output pairs into the T1 Line I/O connector on each MA-260, MA-262
or MA-261 module adapters as applicable.
If your M-DACS is equipped with a Fiber Optic Module, fiber optic connectors must be
connected to the fiber optic heads on the rear panel of the M-DACS chassis. Type ST or FC
series bayonet fiber optic connectors (or their equivalent) are used with both singlemode and
multimode fibers. The exact mating connector used will depend upon the head that is installed
in the fiber optic module, and the specific optic cable being used.
When connecting fiber optic cables, make sure the connectors are properly aligned before
tightening and then fully tighten them. This will help minimize losses in the connector.
WARNING
YOUR M-DACS MULTIPLEXER MAY BE EQUIPPED WITH FIBER OPTIC
INPUT/OUTPUT MODULES THAT HAVE FIBER OPTIC EMITTER HEADS.
FIBER OPTIC EMITTER HEADS USE A LASER LIGHT SOURCE THAT
PRODUCE INVISIBLE RADIATION. FIBER OPTIC COMMUNICATION
SYSTEMS ARE INHERENTLY SAFE IN NORMAL OPERATION BECAUSE ALL
RADIATION IS CONTAINED IN THE SYSTEM. IT IS POSSIBLE DURING
MAINTENANCE TO EXPOSE THE RADIATION BY REMOVING OR BREAKING
THE FIBER. STARING DIRECTLY INTO THE LIGHT BEAM MAY RESULT IN
PERMANENT EYE DAMAGE AND/OR BLINDNESS. NEVER LOOK DIRECTLY
INTO THE LIGHT BEAM AND BE CAREFUL NOT TO SHINE THE LIGHT
AGAINST ANY REFLECTIVE SURFACE.
THE LASER SOURCE IS A CLASS I LASER PRODUCT WHICH COMPLIES
WITH APPLICABLE FDA, OSHA AND ANSI STANDARDS.
