Scsi Cable; System Unit; System Power Supply - Dell 6100 Service Manual

1-10 Dell PowerEdge 6100/200 System Service Manual
The standard SCSI CD-ROM drive is configured as the last device on the SCSI
cable. Therefore, any additional devices attached to the cable should have their
terminators disabled.
See the documentation provided with the SCSI device for information on dis-
abling the device's terminator.

SCSI Cable

CAUTION: Dell recommends that you use only SCSI cables purchased
from Dell. SCSI cables purchased elsewhere are not guaranteed to work
reliably with the Dell PowerEdge 6100 systems.
The 50-pin SCSI cable has six connectors:
•
The connector at the end of the cable farthest away from the other five con-
nectors attaches to the SCSI host adapter connector labeled "SCSI B" on the
system board.
The 50-pin "narrow" cable plugs in to the connector via an adapter.
•
The five connectors on the cable attach to devices in the external drive bays.

The following subsections provide service-related information about the system

System Power Supply

The 700-W system power supply can operate from an AC power source of 90 to
265 VAC at 50 or 60 Hz. The power-supply paralleling board permits the power
supplies to be hot-pluggable. When the fault indicator (red LED) on the power
supply is lit (except during start-up), it indicates that the power supply has
failed (see Figure 1-5). When the online indicator (green LED) is lit, it indicates
that +5 VDC is on. The system power supply provides the DC operating volt-
ages 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 system
board or drives.
