Expansion Interface Packet Interface Test (#589)
This test is nondestructive. This test attempts to send a data packet from the
TN1655 Packet Interface circuit pack through any intervening Expansion
Interface circuit packs and/or Switch Node Interface circuit packs and through
the Expansion Interface circuit pack to be tested. The path the data packet takes
is dependent on the location of the Expansion Interface circuit pack to be tested
and whether the system has duplicate Port Network Connectivity. The following
diagrams and short discussion of each describe the different paths the test uses.
Figure 9-47. Expansion Interface Packet Interface Test—Packet Endpoint Loop
The path shown in Figure 9-47
is used when testing an EPN EI that is on the
active PNC.
Figure 9-48. Expansion Interface Packet Interface Test—PPN to EPN loop
In a Center Stage configuration the path shown in Figure 9-48
is used when
testing an EPN EI that is on the standby PNC. In a Direct Connect configuration,
this path is used on any PPN EI or on an EPN EI that is on the standby PNC.
