POWER (Battery & Battery Charger) for AC-Powered
Systems

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.

Read the section, ‘‘Replacing the Battery and Battery
Charger’’ before proceeding.
