(cont’d.)

MSDL 10:

SYS DSBL—SELFTEST PASSED

NO RECOVERY UNTIL MIDNIGHT: FAILED BASE DNLD 5 TIMES

SDI 10 DIS PORT 0

AML 11 DIS PORT 1

DCH 12 DIS PORT 2

AML 13 DIS PORT 3

Error messages usually indicate the problem in this case. See

“Maintaining the MSDL” (page 405)

SYSTEM DISABLED—SELF-TESTS FAILED

Cause: The card did not pass self-tests. These tests repeat five times. If
unsuccessful, autorecovery stops until midnight unless you take action.

Action:

Allow the system to repeat the self-tests.

If self-tests fail repeatedly, disable the card using the DIS MSDL x
command and replace the card.

SYSTEM DISABLED—SRAM TESTS FAILED

Table 166

Cause: After self-tests pass, the system attempts to perform read/write
tests on the shared RAM on the MSDL and detects a fault. The shared
RAM test repeats five times, and, if unsuccessful, autorecovery does not
resume until midnight unless you take action.

Action:

Allow the system to repeat the self-tests.

If self-tests fail repeatedly, disable the card using the DIS MSDL x
command and replace the card.

SYSTEM DISABLED—OVERLOAD

Table 167

Cause: The system received an excessive number of messages from the
MSDL card in a certain time. If the card invokes overload four times in
30 minutes, it exceeds the recovery threshold as described in "SYSTEM
DISABLED—RECOVERY THRESHOLD." The system resets the card,
invokes self-tests, and attempts to enable the card. The problem may
be due to excessive traffic on one or more MSDL ports. Traffic load
redistribution may resolve this condition.
