Sanity Handshake Test (#106)
This test checks the EPN Maintenance circuit pack’s ability to respond to queries.
A message is sent to the EPN Maintenance circuit pack which then sends a
message back. If the response message is received, then the EPN Maintenance
circuit pack is queried for the EPN cabinet type. The EPN Maintenance circuit
pack reads pins on the backplane of carrier A that identify the type of cabinet and
report this information. If a valid cabinet type is returned, then the test passes.

allowable time period.
2033 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
2046 ABORT The EPN Maintenance circuit pack reported an invalid cabinet
type. Not knowing the cabinet type of the EPN prevents all
EPN environment maintenance from running.
1. Retry the command.
2. If the test continues to abort with 2046, then either the
EPN Maintenance circuit pack is defective, or the EPN
cabinet wiring is defective. First, replace the EPN
Maintenance circuit pack.
3. If the test continues to abort with 2046, then the EPN
cabinet wiring is defective in the A carrier and the EPN
Maintenance circuit pack cannot read the backplane pins
to determine the cabinet type.
10601 ABORT Test disabled via software patch.
FAIL EPN Maintenance circuit pack did not respond to Sanity
Handshake and the test timed out.
1. Verify that the carrier A power units are good. If the -5 volt
unit is defective in the A carrier, then communication with
the EPN Maintenance circuit pack is not possible.
