Dell 2950 owner manual Removing the Front Bezel, Hard Drive and Media Bay Configurations

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 containing the left riser accommodates up to two full-length PCIe or PCI-X expansion cards, while the central riser accommodates one half-length PCIe expansion card.

The system provides space for an optional optical drive. The optical drive connects to the controllers on the system board through the sideplane board. For more information, see "Optical Drive" on page 81.

Depending on the hard drive configuration you ordered, an optional 3.5-inch diskette drive, and an optional tape drive may also be available for installation into a media bay. See Table 3-1 for configuration options.

Table 3-1. Hard Drive and Media Bay Configurations

Number of Hard Drives on Backplane	Hard-Drive Size	Media Bay
6	3.5-inch	No
4	3.5-inch	Yes
8	2.5-inch	Yes

The hard-drive bays provide space for up to eight 2.5-inch SAS drives or six 3.5-inch SAS or SATA hard drives. The hard drives connect to a RAID controller card through the SAS backplane board. For more information, see "Hard Drives" on page 55 and "SAS Controller Daughter Card" on page 69.

During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see "System Board Jumpers" on page 135.
