Test
Result
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 5
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 5 times
per second), refer to the procedures for Test #238.
