10. System Chassis and Sub-Assemblies
10.1 Base Chassis and Top Covers
10.1.1 Base Chassis
The system is designed to fit into a standard 19-inch EIA rack and is 4U high x 28-inches deep. The 4U height is
defined by standard EIA rack units where 1U = 1.75-inches. The depth, as measured from the front mounting flange to
the back of the PCI slots, does not include cables.
The chassis has been designed to be modular for ease of serviceability and manufacturability. All major modules in the
chassis are designed to be easily accessible. Hot-swap component replacement capability is provided for the following:
x System fans
x Hard drives
x Memory boards
x PCI slots* (four out of the ten total slots)
x Power supplies
Except for the DVD-RW kit which requires a #1 Phillips screw driver, the rest of system FRU parts can be handled with
either a #2 Phillips screw driver or bare hands.
10.1.2 Top Cover
The top cover is a single-piece design. It attaches to the chassis with a series of slot features in the sides of the
chassis that mate with features in the top cover.
10.1.3 Slide Rails
The server chassis is designed to accommodate slide rails for mounting the chassis into standard 19-inch racks. The
keyhole features on the slide rails attach to studs on the sides of the chassis. No tools or screws are needed.
