A-6 DAC960PG and DAC960PJ Installation Guide
Maintenance
No end user maintenance is required on the BBU. 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 or
DAC960PJ for replacement or upgrade.
When one of these conditions occur, observe the following precautions:
ᾦ
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.
ᾦ
WARNING
Do not attempt to install, remove, or change a
cache SIMM on the DAC960PG or DAC960PJ
with the BBU installed. Serious damage to the
SIMM and/or the battery backup unit will occur
if this precaution is not followed.
ƽ
Caution
If you plan to operate your DAC960PG or DAC960PJ
without the BBU, be sure to reinstall the loopback
plug (see the “Mechanical Installation Procedure”
section and Figure A-2).
