4.3.7 FINAL CONFIGURATION VERIFICATION
NOTE: Make sure both power supplies are turned
OFF
.
1. Disconnect AC Power Cables from AC power
source.
2. All PTMs should be installed and configured as
follows:
Switch Sections Closed Sections Open
S5, S7 2,5,6,7 1,3,4
S6, S8 2,5,6 1,3,4,7,8
3. Select one of the six Backplane boards for
measuring. Measurements can be made on any of
the
64-pin connectors on the Backplane selected.
4. All measurements should be referenced to ground
(pins 9, 10, 41 or 42) unless otherwise noted.
5. All test readings should be within 5% of the
following specifications:
Pins Ohms
16/48 37.5
17/49 37.5
18/50 37.5
19/51 75.0
20/52 37.5
21/53 37.5
22/54 100 (measured to +5V DC*)
23/55 37.5
24/56 100 (measured to +5V DC*)
* Pins 11, 12, 43 or 44.
6. On the top Backplane board, the following measure-
ments should be referenced to ground (pins 9, 10, 41
or 42).
Center Pin of Ohms
J5 37.5
J6 37.5
J23 19.2
J24 19.2
NOTE: The four readings should be ±1 ohm from
the test specifications.
7. Test is complete.
