2029 ABORT Internal System Error.
1. Retry the command at one-minute intervals a maximum of five times.
2. If the test continues to abort, escalate the problem.
2 FAIL The system is in nominal power holdover, and the battery is currently so low
that the system disconnects power very shortly.
1. If power returns, the port carriers in the PPN should power up again. All
the circuit packs should be reinserted, and the system should continue to
operate normally. There will probably be a Minor alarm against Battery &
Battery Charger because the batteries are recharging.
2. If power does not return, the system shuts down to prevent damage to the
batteries. If power is restored, the system reboots. No manual
intervention is required.
3. Rerun the test. If the test still fails, the PR-MAINT (Maintenance/Tape
Processor) in a multicarrier cabinet PPN system without High or Critical
Reliability, the DUPINT (Duplication Interface) circuit pack in a PPN for a
system with High or Critical Reliability, or the EPN MAINT (Maintenance)
circuit pack in an EPN could be reporting this condition incorrectly.
Resolve all alarms on these MOs and rerun the test. There are failures that
can occur on the Maintenance/Tape Processor, Duplication Interface, and
EPN Maintenance circuit pack that ARE NOT be detected by the
respective maintenance, but that cause many, if not all, environment tests
to fail. If many environment tests are failing, the suspect circuit pack,
depending on the system configuration, should be replaced and the test
rerun. If the test still fails, follow normal escalation procedures.
4 FAIL The battery is currently being charged at the high charge rate.
1. After 30 hours, the battery should be fully charged, and this error should
disappear.
2. If after 30 hours the battery is still in the high charge rate, an alarm is
raised. Display the Error Log with the display errors command and select
the category "environ" to display only environment-related errors. Look for
POWER errors of type 257. The FIRST OCCURRENCE of this error
indicates the time when the battery started charging. Use this time as the
starting point to determine if the battery has been charging for 30 hours. If
the battery has been charging for 30 hours, then replace the battery.
!
CAUTION:
Read the section, ‘‘Replacing the Battery and Battery Charger’’ before
proceeding.
