1. Attach an antistatic wrist strap to your wrist, and then to a metal area on the
chassis.
See Take Antistatic Measures.
2. Carefully lift and place the motherboard assembly into the chassis.
While holding the motherboard mid-wall handle with one hand and the small
plastic handle at the front corner with the other, lower the motherboard into the
chassis. You need to tilt the motherboard downward towards the back of the
chassis so that it fits under the sheet metal housing for the power supply and then
lay the motherboard flat into the server chassis. Slide the motherboard to the back
of the server to engage the raised standoffs.
Caution:
Be careful not to damage the rear Locate Button/LED when placing the
motherboard into the chassis.
3. Using a Torx T25 screwdriver, tighten the two captive screws to secure the
motherboard mid-wall to the chassis.
4. Replace the cable guide on the side of the chassis wall (on the left side when
facing the front of the system) that secures various cables against the chassis side
wall.
5. Reconnect the disk backplane Power cable [1], disk backplane Aux Signal cable
[2] and front LED indicator module (FIM) ribbon cable [3] to their connectors on the
motherboard.
