PROCEDURE B
Use Procedure B if the Expansion Interface circuit pack to be tested is in an
EPN and is part of a Standby link from the PPN to the EPN or if the Expansion
Interface circuit pack to be tested is in the PPN.
1. Test the Packet Control circuit pack. 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 EPN
Expansion Interface circuit pack. If the circuit pack being tested is in the
PPN and is part of an Active link from the PPN to the EPN and 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 PPN Expansion Interface circuit pack and the
connected EPN Expansion Interface circuit pack and follow the
procedures for Test #242. Otherwise, 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 connected EPN Expansion Interface circuit
pack.
3. If the test was not run on an active PPN Expansion Interface circuit pack,
issue the test board PCSS long command on both Standby Expansion
Interface circuit packs and follow the procedures for Test #242.
More information follows.
FAIL
(cont’d.)
PROCEDURE C
Use Procedure C if the Expansion Interface circuit pack to be tested is part of
any link from EPN to EPN.
1. Test the Packet Control circuit pack. 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 the
Expansion Interface circuit packs of the EPN to EPN link or on the EPN
Packet Bus.
3. Issue the test board PCSS long command on both EPN to EPN
Expansion Interface circuit packs and follow the procedures for Test
#242.
PASS The data packet was received correctly.
1. Refer to other Expansion Interface circuit pack tests if the Expansion link
is not functioning correctly.
