OWERING
UP
AND
TESTING
A.
On shelves A, B, and C connect the redundant battery supplies to
barrier strip terminals 1 and 2, and connect ground to terminal 3.
B.
Use the DB15 connector C1, of shelf A, to connect the assembly to
the East port of the fiber optic equipment. Use connector C2 of
shelf A to connect to the West port of the fiber equipment.
C.
Insert all of the modules in the shelf, starting at slot 1 of shelf A.
When a Fuse Module is installed in slot 14 of shelf A, B or C, power
will be applied to that shelf. Inserting the fuse module in shelf C
will also place power on shelf D. Shelf D fuse protection is con-
trolled by fuse FA of shelf C.
D.
When the units first power up the 46112 TX REPEAT LED will
blink on and off at a one second rate. If the 46112 continues to
flash, it is an indication that there is a wrong switch setting on a
46113 module.
E.
Remove the fuse from the fuse module for Shelf A, slot 2 (Shelf A
slot 14 fuse #2). MAT alarm point #2 should come on. After observ-
ing the failure on the MAT replace the fuse. This is the East DSM
power supply monitor alarm.
