Reset the circuit pack by executing the busyout board PCSS, reset
board PCSS, and release board PCSS commands. When it is reset, the
circuit pack executes a set of tests to detect the presence of any of the
above faults. The detection of one these errors during initialization causes
the circuit pack to lock-up and appear insane to the system. See the
repair procedures in footnote (a) for error type 1.
e. The circuit pack detects a program logic error. While no action is required,
this error may lead to errors of other types being reported against this
circuit pack.
f. The circuit pack cannot update NPE memory and read it back. This error
type can be ignored, but it may lead to other error types being reported
against this circuit pack.
g. A critical hardware failure has been detected on the circuit pack. Use
busyout board PCSS, reset board PCSS, followed by release board
PCSS. If test #53 passes, the on-board circuitry is healthy. Use test board
PCSS long clear to retire the alarm. If test #53 fails, replace the circuit
pack.
h. The circuit pack detected a critical hardware failure. Reset the circuit pack
by issuing the busyout board PCSS, reset board PCSS, and release
board PCSS commands. If the Circuit Pack Restart Test (#594) passes,
then the on-board circuitry is healthy. Retire the alarm by issuing the test
board PCSS long clear command. If the Circuit Pack Restart Rest (#594)
fails, replace the circuit pack.
The reported error types correspond to the following detected errors:
i. The circuit pack is hyperactive — it is flooding the switch with messages
sent over the control channel. The circuit pack is taken out of service when
a threshold number of these errors is reported to the switch. Clear the
alarm by using busyout board PCSS, reset board PCSS, test board
PCSS long clear, and release board PCSS. If the error recurs within 10
minutes, then replace the circuit pack.
