Additional Memory (RAM)(BT’03, October 2003) - BEP2.2
Additional memory was added to the motherboard for R3.0.0 Software and BT’03. one of the 256 MByte
SIMM modules was replaced with a 512 MByte module. This brings the total RAM memory to
768MBytes and designated the unit to be a BEP2.2.

DGVIC/DGIO Upgrade
It is possible that older P3 Back End Processor video chains could be upgraded to digital. This involves
replacing the Analog AGP Video card with a Matrox video card that has analog and video outputs.
The PC2IO/PCVIC Tray assembly is also replaced with the DGIO/DGVIC Tray.
Digital video is supplied by the Matrox video card to the DGVIC for distribution to peripherals. Monitor
video is taken directly from the Analog output of the Matrox video card instead of the DGVIC.

UPS Battery Operation
The UPS batteries provide power to the Back End Processor to enable a controlled shut down of the
processor. The UPS batteries will drain slightly when the system is in the off condition. The off condition
is defined as:
-
Circuit Breaker in the OFF position
-
System unplugged from the wall outlet
If the system is left in the OFF condition for an extended period of time (3 to 5 days or more), the system
may not boot up or may beep when turned ON. Should this occur, the system needs to recharge the
UPS batteries. This could take 15 minutes to as long as 24 hours, depending on the battery age, system
input voltage and system temperature.
To eliminate draining the UPS batteries, the system should remain plugged into the wall outlet with the
circuit breaker in the ON position.
The expected life of the battery is approximately three (3) years.
