Dell PowerEdge 2850 - Manual (Page 32)

In Figure 5 -1 , the covers and bezel are removed to provide an interior view of the system.
Figure 5-1. Inside the System
The system board holds the system's control circuitry and other electronic components. Several hardware options, such as the microprocessors and memory,
are installed directly on the system board. The expansion-card cage accommodates up to three full-length PCI, PCIe, or PCI-X expansion cards.
The system provides space for a 3.5-inch diskette drive and an optical drive. The optical drive and the diskette drive trays connect to the controllers on the
system board through the SCSI backplane board. For more information, see "
Installing Drives ."
The hard-drive bays provide space for up to six 1-inch SCSI hard drives. The hard drives connect to a controller on the system board or a RAID controller card
through the SCSI backplane board. For more information, see "
Installing Drives ."
During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see " Jumpers and Connectors ."
