processor prior to any register access. There are two parts to the test. Part 1
involves navigating the Sanity Maze to toggle an unused lead. Part 2 attempts to
toggle an unused lead without first navigating the Sanity Maze. The Sanity Maze
test passes if Part 1 is successful and Part 2 fails.
EPN Maintenance Circuit Pack Reset Test (#306)
This test is destructive.
The EPN management terminal is dropped and, if the Emergency Transfer switch
is in the AUTO position, Emergency Transfer is disabled for the duration of the
test.
The EPN Maintenance circuit pack is reset by the Active Expansion Interface
circuit pack. After the Expansion Interface circuit pack reports that the EPN
Maintenance circuit pack has reset, a handshake message is sent to the EPN
Maintenance circuit pack. If the EPN Maintenance circuit pack responds to the
handshake, the test passes. If not, it fails. If the test passes, the EPN Manager I
(G1) or G3MT is brought back up, and Emergency Transfer is restored to its
previous state.

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
2000 ABORT Response to the test request was not received within the allowable time
period.
2033 ABORT 1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL The Sanity Maze of the EPN Maintenance circuit pack is defective.
1. Replace the EPN Maintenance circuit pack.
PASS The Sanity Maze is working properly, and the EPN Maintenance circuit pack
can access the unused register. If recycle carrier commands (for EPN
carriers) do not work, the following problems may still exist:
1. The Carrier Port Power Unit or wiring to the Carrier Port Power Unit may
be defective. Refer to CARR-POW (Carrier Port Power Unit)
Maintenance documentation.
2. Since this test only tests the EPN, there is a very small probability that
the EPN Maintenance circuit pack cannot access those registers that
deal with EPN devices. The EPN Maintenance circuit pack may need to
be replaced.
