Error Test
Code Result Description / Recommendation
FAIL The test failed because no neon current was detected.
1. Determine if there is a TN755 or TN752 power unit circuit pack installed in
2. Retry the command again.
3. If the test continues to fail, replace the circuit pack.
4. Retry the command again.
PASS This circuit pack is a TN746 or TN769 Analog Line circuit pack and the neon
current is detected. If this test passes, it can also mean that this circuit pack is
not a TN746 or TN769 Analog Line circuit pack.
Any NO This is normal if the test is being done when (a) the board is not physically in
BOARD 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 board is physically in the system.
2. Verify that the system is not in a stage of booting up.
3. Retry the command at 1-minute intervals up to 5 times.

the same carrier as the TN746 or TN769 analog line circuit pack that failed
the test. Look for the failure of test 220 on other TN746 or TN769 circuit
packs in the carrier. If test 220 fails on the other circuit packs, replace the
TN755 or TN752 power unit circuit pack.
