Dell PowerEdge 6100/200 System Service Manual
The ten expansion-card slots consist of four EISA expansion-card connectors
and six PCI expansion-card connectors. The expansion-card connectors are
located on the system board (see Figure 1-14).
Integrated Server Management
The system board contains integrated server management circuitry that moni-
tors critical system voltages and temperatures, as well as the operation of the
system cooling fans. The integrated server management circuitry works in con-
junction with the Intel LANDesk
®
Server Management software and the Dell
Hardware Instrumentation Package (HIP) software.
Video Controller
The video subsystem (Cirrus Logic CL5424) is built in to the system board and
consists of a high-speed, high-resolution, SVGA-compatible video subsystem.
The video controller is connected to the EISA local bus. The standard video
subsystem contains 1 MB of DRAM memory (the video memory size is not
upgradable).
Maximum noninterlaced resolutions are 800 x 600 pixels with 16.7 million
colors, 1024 x 768 pixels with 65,536 colors, and 1280 x 1024 pixels with
256 colors.
Integrated SCSI Controllers
Two built-in Adaptec 7880 Ultra/Wide SCSI controllers provides ultra-wide
fast SCSI interfaces through 68-pin connectors on the system board. One SCSI
controller attaches to a PCI bus to provide a high-performance SCSI bus and
also controls the six SCSI hard-disk drives in the SCSI hard-disk drive bays. In
the standard Dell PowerEdge 6100 system configuration, one Ultra/Wide SCSI
host adapter on the system board controls the SCSI backplane board. When
used in combination with an optional PowerEdge Expandable RAID Controller
host adapter card, the SCSI backplane board allows you to remove and insert
hard-disk drives without shutting down the system.
Another built-in 7880 Ultra/Wide SCSI controller provides a SCSI interface to
the CD-ROM drive in the externally accessible drive bays and to any other
SCSI drives installed in the other two bays. This controller also provides a SCSI
interface to external SCSI devices.
SCSI Hard-Disk Drives
Six internal, hot-pluggable hard-disk drive bays are located under the externally
accessible drive bays at the front of the computer (see Figure 1-3). These bays
can contain up to six 1- to 1.6-inch-high SCSI hard-disk drives.
NOTES: The externally accessible drive bays at the front of the computer are
normally used for diskette drives, CD-ROM drives, and/or tape drives. Hard-
disk drives should be installed in the SCSI hard-disk drive bays. For detailed
information about installing externally accessible drives, see Chapter 9, “Installing
Drives in the External Bays,” in the Installation and Troubleshooting Guide. For
