2500 ABORT An internal operation failed; the test could not be completed.
1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL The transmitted data packet was not received correctly by the Packet 
Control circuit pack. If there are any PKT-BUS errors in the Error Log, 
attempt to resolve those errors before investigating these test failures.
PROCEDURE A
Use Procedure A if the Expansion Interface circuit pack to be tested 
is in an EPN and is part of an Active link from the PPN to the EPN.
1. Test the Packet Control circuit pack via the test packet-control 
command. If the Packet Control circuit pack fails any tests, refer 
to the PKT-CTRL Maintenance documentation for recommended 
maintenance procedures.
2. If all Packet Control circuit pack tests pass, the failure may be in 
either the PPN Expansion Interface circuit pack or the connected 
Expansion Interface circuit pack under test or on the EPN Packet 
Bus. If a duplicate Expansion link exists, make that the Active link, 
using the set expansion-link PCSS command. Execute the test 
board long command on the original Expansion Interface circuit 
pack and the connected PPN Expansion Interface circuit pack 
and follow the procedures for Test #242.
3. If a duplicate link does not exist, run the Long Test Sequence on 
the PPN Expansion Interface circuit pack. If Test #242 fails, follow 
the procedures for Test #242. If Test #242 passes, the fault is in 
the EPN Expansion Interface circuit pack under test or on the EPN 
Packet Bus.
