System Features - Dell PowerEdge 6850 User Manual

The indicators on the redundant power supplies show whether power is present or whether a power fault has occurred (see
NOTE: The 1470-W power supplies require 200–240 V to operate. If they are plugged into 110-V electrical outlets, the power supplies do not power up.
Table 1-5. Redundant Power Supply Indicators
Indicator Function
Power supply status Green indicates that the power supply is operational.
Power supply fault Amber indicates a problem with the power supply.
AC line status Green indicates that a valid AC source is connected to the power supply.

System Features
Up to four Intel® Xeon™ processors with an internal operating speed of at least 3.16 GHz, internal cache of at least 1 MB, and a front-side bus
l
operating at 667 MHz.
Support for symmetric multiprocessing (SMP), which is available on systems with up to three additional Intel Xeon processors. SMP greatly improves
l
overall system performance by dividing processor operations between independent processors. To take advantage of this feature, you must use an
operating system that supports multiprocessing.
NOTE: If you decide to upgrade your system by installing additional processors, you must order the processor upgrade kits from Dell. Not all
versions of the Intel Xeon processor will work properly as additional processors. The upgrade kit from Dell contains the correct version of the
processor and heat sink, as well as the instructions for performing the upgrade. All processors must have the same internal operating frequency
and cache size.
A minimum of 512 MB of registered PC2-3200 DDR 2 400 SDRAM memory modules, upgradable to a maximum of 64 GB by installing combinations of 256-
l
MB, 512-MB, 1-GB, 2-GB, or 4-GB (when available) 2-way interleaving memory modules in up to four hot-pluggable memory risers on the system board.
NOTE: The chip fail feature is only supported using x4 and x8 memory modules.
The system also features redundant memory, which provides memory mirroring, a failover memory bank, or memory RAID. These features are selectable
through the System Setup program when memory configuration requirements are met (see
Support for up to five 1-inch, internal hot-pluggable U320 SCSI hard drives. An optional daughter card provides support for a 2+3 split backplane.
l
An optional Integrated Fibre Channel Module, incorporating two 2-GB connectors.
l
An optional single, 1.44-MB, 3.5-inch diskette drive.
l
An optional IDE CD, DVD, or combination CD-RW/DVD drive.
l
NOTE: DVD devices are data only.
An intrusion switch that signals the appropriate systems management software if the top cover is opened.
l
Two hot-pluggable, 1470-W power supplies in a 1 + 1 redundant configuration.
l
Four redundant, hot-pluggable system cooling fans.
l
The system board includes the following features:
Seven PCI slots. PCI slot 1 is a hot-pluggable PCIe x8 lane slot; slot 2 is a hot-pluggable 64-bit, 133-MHz PCI-X slot; slots 3 through 5 are hot-
l
pluggable PCIe x4 lane slots; and slots 6 and 7 are 64-bit, 100-MHz PCI-X slots. Expansion-card slots 1 through 6 accommodate full-height, full-length
expansion cards. Slot 7 is a full-height, half-length slot.
An integrated, dual-channel U320 SCSI host adapter. The internal channel supports up to five SCSI hard drives using the 1x5 or, with the optional
l
daughter card installed, the 2+3 SCSI backplane. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination, greatly
simplifying drive installation.
Optional ROMB activated by using a ROMB key, a 256-MB DDR2 400 memory module, and a RAID battery.
l
Optional RAID through a separate controller card that incorporates 128 MB of cache memory and a RAID battery.
