FAIL The Expansion Interface circuit pack under test cannot make contact with
opposite end Expansion Interface circuit pack.
1. If Test #238 passes (yellow LED not blinking at a rate of five times per
second), the Expansion Interface circuit pack is detecting the framing
signal and an Expansion Interface circuit pack is at least physically
present on the opposite side.
a. Reset the OPPOSITE Expansion Interface circuit pack using the reset
board PCSS command where PCSS is the address of the OPPOSITE
Expansion Interface circuit pack.
b. If the reset command returns the message "EPN is unavailable," use
the change circuit-pack command to add a TN776/TN570
Expansion Interface circuit pack to the correct EPN slot. Then, repeat
the reset board command.
c. If the reset command returns the message "Board not Assigned," the
EPN Maintenance circuit pack may be holding the Expansion
Interface circuit pack reset. First, try to reset the EPN Maintenance
circuit pack using the test maintenance long command. Then,
repeat the reset board command on the EPN Expansion Interface
circuit pack.
d. If the reset does not pass, refer to the Expansion Interface Reset Test
(#336).
e. If the reset passes, execute the test board PCSS command on the
opposite Expansion Interface circuit pack. Resolve all problems on
the opposite Expansion Interface circuit pack before proceeding.
f. If this test still does not pass, try replacing the Expansion Interface
circuit pack on which this test is failing.
2. If Test #238 fails (yellow LED is blinking at a rate of five times per
second), refer to the procedures for Test #238.
PASS The Expansion Interface circuit pack has successfully established a link with
the opposite Expansion Interface circuit pack.
1. If the status system command still indicates that this link is down, it is
possible that one or both of the Expansion Interface circuit packs have
been busied out.
2. If the link still does not come up, reset one or both Expansion Interface
circuit packs on the link.
