system; the upgrade kit from Dell contains the correct version for this system. A secondary (L2) cache of 512 KB of SRAM included within the SEC cartridge that contains the microprocessor. 64-MB and 128-MB (unbuffered) main memory, upgradable to 512 MB, or upgradable to 1 GB using 256-MB registered SDRAM DIMMs. BIOS in upgradable flash memory on the ISA bus. Up to six hot-pluggable SCSI hard-disk drives. Two additional 1-inch drives can be installed in the optional removable media bay. Up to three redundant, hot-pluggable power supplies and a power-supply paralleling board (PSPB), which is necessary for systems with two or more power supplies. Five redundant system cooling fans. Six 32-bit PCI connectors and two shared 8-bit or 16-bit ISA connectors. PCI and AGP local buses and ISA bus. A VGA-compatible video subsystem with an ATI 3D Rage Pro AGP video controller. This video subsystem contains 2 MB of SGRAM video memory (nonupgradable). A National Semiconductor PC87309 super I/O controller that controls the bidirectional parallel port, two serial ports, and the diskette drive in the externally accessible front bay. An integrated Adaptec AIC-7890 Ultra2/LVD SCSI-3 host adapter that supports up to six 1.6-inch internal SCSI hard-disk drives via a SCSI backplane board and special SCSI hard-disk drive carriers. NOTE: The 1.6-inch drive carriers will accommodate 1-inch drives. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly simplifying drive installation. The backplane supports hot-pluggable SCSI hard-disk drive installation and removal when used in conjunction with a PowerEdge Expandable RAID Controller. An integrated Adaptec AIC-7860 Ultra/Narrow SCSI-3 host adapter that supports the standard CD-ROM drive and two additional externally accessible SCSI devices in the external hard-disk drive bays. Drive failure, online, and activity indicators visible on each hard-disk drive connected to the SCSI backplane. Server management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The server management circuitry works in conjunction with the HP OpenView Network Node Manager Special Edition (NNM SE) and the Dell OpenManage™ Hardware Instrumentation Package (HIP). System board support for the Dell OpenManage Remote Assistant when the optional Dell Remote Assistant Card version 2 (DRAC 2), which provides additional local and remote server management, is installed. 1-2 Dell PowerEdge 4300 Systems Service Manual
