Result:
The Response Window should display the command
followed by a
COMPLD
indication as well as indicating:
•
Correct line coding and frame format
•
Provisioned and active timing mode are both external
•
Both references are in service (is)
•
Which of the two references is active.
Important!
If a reference does not indicate is, that input is not
receiving a proper timing reference. Verify:
–
cabling between the timing source and the Metropolis
®
DMXtend shelf
–
correct line coding
–
correct frame format.

Step 10
At the rear of the shelf (see Figure 5-1, Metropolis® DMXtend Shelf
Backplane (page 5-22), disconnect the input timing cable from the
connector associated with the active reference.
Requirement:
The
MN
LED lights solid on the SYSCTL and the
FAULT
LED flashes on the MAIN OLIU circuit pack associated with
that reference (SYNC1 is associated with M1 and SYNC2 is associated
with M2).
