6-5 Power Supply
The SERIES3800/S120T (7045A-C3/7045A-CT) has a single 865 watt power sup-
ply. This power unit is equipped with low-noise technology, making the system ideal
for workstation environments.
The power supply has an auto-switching capability that enable it to automatically
sense and operate with 100 or 240 volt inputs.

the power supply unit. Replace with the same model - PWS-865-PQ, which can be
