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:

￿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 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.

￿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).
