12 Volt Power Supply Test (#701)
This test is nondestructive.
The purpose of the test is to diagnose the 12 volt power supply unit in the
TN777B NETCON circuit pack. No erase and write-to-memory operations are
started or verified during the test. The contents of flash memory and of the
memory card should not be changed.
The test turns on the power supply, and it verifies that 12 volt power appears by
reading the control register in the TN777B NETCON circuit pack. After the power
supply is turned on, the maintenance software waits for three seconds before
verifying the appearance of 12 volt power. After the 12 volt power supply can be
turned on and verified, the test turns the power supply off and then verifies that
1. D = Destructive; ND = Nondestructive
