Reset the circuit pack with the busyout board PCSS and reset board
PCSS commands. When reset, the circuit pack executes a set of tests to
detect the presence of any of the faults listed above. Detection of one of
these errors during initialization causes the circuit pack to lock-up and
appear insane to the system. See the repair procedure in Note (a).
d. The circuit pack detects a program logic error. While no action is required,
this error can lead to other errors against this circuit pack.
e. The circuit pack cannot update and read back NPE/NCE memory. This
error can be ignored, but may lead to other errors against this circuit pack.
f. The TN2185 board notifies maintenance software that it has detected a
parity error while accessing its dynamic RAM (that stores the board’s
translation information and downloadable application firmware).
Maintenance software resets the circuit pack.
g. Unable to write LAN Translation RAM Error (internal memory access error).
Translation RAM locations for the call connection attempt are not
available, and one or more RAM locations are bad due to a translation
RAM read-back error. Reset the circuit pack with the busyout board
PCSS and reset board PCSS commands. If the Circuit Pack Restart Test
(#594) passes, then the on-board circuitry is healthy. Retire the alarm with
the test board PCSS long clear command. If the Circuit Pack Restart Test
(#594) fails, replace the circuit pack.
h. Frame overrun at Packet Bus interface. Due to an on-board fault or by
faulty data received on one of the circuit pack’s external ports. If any of the
ports on this circuit pack is alarmed, refer to the repair procedures for
those maintenance objects. If this error persists, maintenance software
removes the board from service; replace the circuit pack.
i. The circuit pack is has problems transmitting/receiving data to/from the
Packet Bus.
1793 Parity errors are detected when transmitting data to the
Packet Bus.
