processor prior to any reg ister access. There are two parts to the test. Part 1
involves navigating the Sanity Maze to togg le 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 terminal connection will be d ropped and , if the Emergency Transfer switch is
in the AUTO position, Emergency Transfer will be disabled for the duration of the
test.
The EPN Maintenance circuit pack is reset b y the Active Expansion Interface
circuit pack. After the Expansion Interface circuit p ack reports that the EPN
Maintenance circuit p ack has reset, a handshake messag e is sent to the EPN
Maintenance circuit p ack. If the EPN Maintenance circuit p ack responds to the
handshake, the test passes. If not, it fails . If the test passes, the EPN-connected
terminal is brought bac k up, and Emergenc y 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 was not received within the allowable time period.
2033 ABORT 1. Retry the command at one-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 command s (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 ma y 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 Mainten ance circuit pack may need to be replaced.
