Chapter 1 System Overview The Dell® PowerEdge® 2200 systems are high-speed, upgradable, server systems that use the Intel® Pentium® II family of microprocessors with MMX™ technology. PowerEdge 2200 systems incorporate the high-performance PCI local bus as well as the EISA expansion bus. The systems have been designed for better serviceability, increased reliability, SCSI hard-disk drives, thermal and power supply monitoring, and extendeddata out (EDO) DIMMs that support ECC. The PowerEdge 2200 systems are freestanding or can be rackmounted for integrating your servers. The microprocessor(s) are mounted in modules on the system board, which allows for greater heat dissipation. Contact Dell for information about Dell-supported microprocessor upgrades. PowerEdge 2200 systems may have one or two Pentium II microprocessors. The microprocessor contains a built-in clock multiplier circuit, which increases the internal operating frequency to a multiple of the system clock frequency. The microprocessor has an internal operating frequency of 233 or 266 MHz and a system clock frequency (that is, external operating frequency) of 66 MHz. System Features In addition to the standard features found in a traditional personal computer, Dell PowerEdge 2200 systems include the following new and/or advanced features: • 512 KB of cache memory internal to each Pentium II microprocessor module • 32 MB of 72-bit-wide, buffered, EDO-type main memory, upgradable to 512 MB • Memory ECC feature built into the memory controller on the system board • Advanced combination EISA and PCI expansion subsystems • Three EISA and three PCI expansion-card slots (none of which are shared) • Integrated VGA-compatible video subsystem attached to the PCI bus, with 1 MB of video memory standard • BIOS in upgradable flash memory attached to the EISA bus • Integrated super I/O controller, attached to the EISA bus, that controls a bidirectional parallel port, two serial ports, and the diskette drive interface • Integrated Ultra/Wide (fast-20) SCSI controller System Overview 1-1
