Hardware setup
1-1
2.1Chassis cover
The chassis features a “screwless design” that allows convenient assembly and disassembly.
•Remove the front bezel to access the hot-swap HDDs, optical drive, and floppy drive.
•Remove the chassis cover to access the internal components or if you want to install system devices.
2.1.1Removing the front bezel
To remove the front bezel:
1.Hold the sides of the front bezel, then slightly press the middle part to disengage it from the front panel.
Press here to release
2.Pull the bezel from the front
panel.

2.1.2Removing the top cover
Front half
To remove the front half of the top cover:
1.Push the two sliding locks on the top cover to release.
2.With both hands, flip up the front corners of the top cover, then lift.
The front corners of the cover have dents that match those on the chassis. These dents provide a holding mechanism and keeps the cover in place even when the sliding locks are released.
Matching d e n t s
If you wish to access the hot-swappable system fans, backplanes, optical drive, and floppy drive, you only need to remove the front half of the top cover.

Rear half
You need to remove the front half of the top cover before you can remove the rear half of the top cover. Refer to section “2.1.1 Removing the top cover (front half)” for instructions.
To remove the rear half of the top cover:
1.Loosen the thumbscrew that secures the top cover on the rear part of the chassis.
Thumbscrew
2.Remove the screw on the rear half of the cover.
3.Firmly hold the rear half of the top cover, then remove it from the chassis.
The barebone server without the top cover is shown on the right.

2.1.3Installing the top cover
To install the top cover:
1.Place the rear half of the top cover over the chassis as shown, and align the mid-hooks with the notches on the sides.
2.Slide the cover toward the front panel until the mid-hooks are locked into the notches.
3.Flip down the front half part of the top cover.
4.Push the sliding locks toward the front edge to secure the front half of the top cover in place.

2.1.4Removing the air duct
To remove the air duct:
1.Carefully route the cables that may interfere when removing the air duct.
2.Hold the rear part of the air duct and press it for about a fraction of an inch, just enough to tilt the front end.
3.When tilted, carefully pull the air duct upward to release it from the chassis.
Be careful not to pull off or break any cables while removing the air duct.
2.1.5Installing the air duct
To install the air duct:
1.Take note of the parts of the air duct that should match specific locations inside the chassis.
Metal strips to fit the plastic clips on the air duct
Plastic clips to grip the metal strips on the fan cage
CPU heatsinks |
Flat rubber pad should match |
|
the top of the two heatsinks |
2 - 6 |
Chapter 2: Hardware setup |
2.Position the air duct inside the chassis with the plastic clips matching the two vertical metal strips on the fan cage.
3.Check the rubber pads underneath the air duct and ensure that they are in place; otherwise, the air duct will not fit properly.
4.Fit the other end of the air duct making sure that no power cable is strayed under it.
Be careful not to pull off or break any cables while installing the air duct.
5.When the air duct is in place, arrange the power cable cluster to fit the space beside the air duct.
6.Flatten the power cable that runs across the air duct. When properly installed, the air duct should appear as shown.

2.2Central Processing Unit (CPU)
The motherboard comes with two surface mount 604-pin Zero Insertion Force (ZIF) socket and designed for the Intel® Xeon™ processors.
Note in the illustration that the CPU has a gold triangular mark on one corner. This mark indicates the processor Pin 1 that should match a specific corner of the CPU socket.

2.2.1Removing the CPU heatsink
You must remove the CPU heatsink(s) before installing the CPU(s).
To remove the CPU heatsink:
1.Use a Phillips (cross) screwdriver to loosen the four screws that secure the heatsink until it is released.
You don’t need to detach the screws from the heatsink.
2.Carefully lift the heatsink from the motherboard.
3.Remove the rubber pad(s) on top of the CPU socket(s).
Remove the rubber pad(s) only when you are ready to install the CPU(s).

Chapter 2: Hardware setup |
4.Remove the rubber pad(s) on top of the CPU socket(s).
Remove the rubber pad(s) only when you are ready to install the CPU(s).
2.2.2Installing a CPU
• The motherboard supports either one or two CPUs. If you are installing only one CPU, you MUST install it in CPU socket 1.
•If you are installing two CPUs, install in the CPU socket 2 first.
CP U Socke t 1 (outer socket)
CP U Socke t 2 (inner socket with rubber pad)
Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!
To install the CPUs:
1.Locate the CPU1 socket on the motherboard. Flip up the socket lever and push it all the way to the other side.
Make sure that the socket lever is pushed back all the way. Otherwise the CPU does not fit in completely.

2.Position the CPU above the socket as shown.
3.Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!
4.Carefully push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.
5.Peel off the plastic film of the thermal grease strip.
