Emergency Transfer Query Test (#124)
This test queries the hardware for the state of the Emergency Transfer switch (or
switches in a High or Critical Reliability system) and reports the result. If the
switch(es) is (are) in a position where the system software can control Emergency
Transfer, then the test passes. If the switch(es) is (are) in a position where the
system software cannot control Emergency Transfer, then the test fails. In the
PPN, the Maintenance/Tape Processor controls Emergency Transfer and, in the
EPN, the EPN Maintenance circuit pack controls Emergency Transfer. The
system software does not have control of Emergency Transfer within a cabinet if
the switch(es) is (are) in the manual ON or manual OFF state for that cabinet.

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2000 ABORT Response to the test request was not received within the
allowable time period.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If the test continues to ABORT with error code 2000, check
for system powering problems with the A carrier (PPN or
EPN). Resolve all DC-POWER alarms. Then, repeat the
test.
3. If the test continues to ABORT with a 2000 error code,
check for and resolve all DUPINT (Duplication Interface)
errors in a PPN for a high or critical reliability system, or
MAINT (EPN Maintenance circuit pack) errors in an EPN.
Repeat the test.
