In Figure3-1, the bezel, system cover, and memory cooling shroud are removed to provide an interior view of the system.

Figure 3-1. 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 left and center risers each have one slot and can accommodate two half-length PCIe expansion cards. For more

information, see Expansion Cards.

The system provides space for one optional slimline optical drive. The optical drive tray connects to the controller on the system board through the sideplane

board. For more information, see Installing the Optical Drive Tray.

The hard-drive bays provide space for up to two 3.5-inch SAS/SATA hard drives. The hard drives connect to a SAS RAID controller daughter card. For more

information, see Installing a Hot-Plug Hard Drive.

During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see Jumpers and Connectors.

Removing and Replacing the Front Bezel

outlet and peripherals.



2. Using the system key, unlock the bezel.



3. Press the tab at the left end of the bezel.
