Neon Test (#220)
This test checks the voltage required to light the neon lamp on an analog
terminal. A relay connects a 150V DC source from the backplane of the circuit
pack onto the voltage bus, and another relay connects a 2K shunt from the bus
to ground. Current in the line is then monitored to determine if the voltage is
present.
The neon test runs only for TN746 and TN769 Analog circuit packs. If the circuit
pack is not a TN746 or TN769, the test returns PASS, but there is no testing done
to the circuit pack.
any NO
BOARD
This is normal if the test is being done when (a) the
circuit pack is not physically in the system or (b) the
system is booting up. Otherwise, there is some
inconsistency between the physical configuration and
the data kept in the system.
1. Verify that the circuit pack is physically in the
system.
2. Verify that the system is not in a stage of booting up.
3. Retry the command at one-minute intervals for a
maximum of five times.
4. If the test continues to return NO BOARD, escalate
the problem.
