System Overview 1-7
‡
A SCSI tape drive is configured as SCSI ID 6 (the default ID number for a
tape drive).
‡
A SCSI CD-ROM drive is usually configured as SCSI ID 5.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or
that devices be attached to the cable in order by ID number.

All Dell PowerEdge 2300 systems have an active terminator installed at the
end of the SCSI cable.
All of the devices attached to the SCSI cable should
have their termination disabled.

The 300-W system power supply can operate from an AC power source of
115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supply provides the
DC operating voltages and currents listed in Table 1-1.
NOTE: The power supply produces DC voltages only under its loaded condi-
tion. Therefore, when you measure these voltages, the DC power connectors
must be connected to their corresponding power input connectors on the sys-
tem board or drives.

The power-supply output voltages can be measured at the back (wire side) of
the connectors without disconnecting them. Figures 1-5, 1-6, and 1-7 show the
wire side of the connectors.
