Installation guide

IBBU Option
Manual Number 775012 A-5
Maintenance
No end user maintenance is required on the IBBU. It is recommended,
however, that the battery charge level be periodically checked using the Gas
Gauge function in GAM (see the
Global Array Manager Client Software
Installation Guide and User Manual
).
Removing the Battery Backup Module
The battery backup module will need to be removed for one of the following
reasons:
1. The NiCd battery will no longer accept a charge properly (NiCd battery
life expectancy is approximately 5 years).
2. The cache memory needs to be removed from the DAC960PG/PJ for
replacement or upgrade.
When one of these conditions occur, observe the following precautions:
, WARNING
Replace the battery only with the same or
equivalent type of battery recommended by the
battery manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
, WARNING
Do not attempt to install, remove, or change a
cache SIMM on the DAC960PG/PJ with the IBBU
installed. Serious damage to the SIMM and/or the
battery backup unit will occur if this precaution is
not followed.
m Caution
If you plan to operate your DAC960PG/PJ without the
IBBU, be sure to reinstall the loopback plug (see the
“Mechanical Installation Procedure” section and
Figure A-2).
