Power Supplies
The cc2300 server system may be configured with either an AC-or DC-input power subsystem.
Power from the power subsystem is carried to internal system boards and peripheral devices via
discrete cables.
The non-hot-swap 250 Watts power supply module is capable of handling the worst-case power
requirements for a fully configured cc2300 server system. This includes two
Pentium III processors, 6 GB of memory and two hard drives at 18 Watts per drive (typical worst
case 3.5-inch by 1.0-inch, 15k RPM drive).
The power supply is accessed from the rear of the chassis.
Only the DC input version is NEBS certified.
DC Power Subsystem
This section defines the features of the DC input switching power subsystem. The DC power
supply front panel, visible from the server chassis back panel, is shown in Figure 8.
