Install the Motherboard

Installing the motherboard is a cold-service operation. You must power off the server before installing the motherboard.

1. Position the motherboard for installation into the server.

   The heatsinks are toward the front of the server, and the ports are at the rear.

2. Lift the motherboard by the handles, and slowly lower the motherboard into the chassis.

   Caution  -  Take care when using the handles to install the motherboard. These handles are not in weight-balanced locations. Avoid flexing the motherboard.

   Caution  -  Take care to clear the four screws at the rear of the chassis. The screws are long and might scratch or damage the motherboard.

5. Slowly slide the motherboard until it drops, engaging the bottom alignment pins.
6. Carefully insert the LED into the hole at the rear of the chassis.
7. Continue to slide the motherboard forward until it seats.

   The rear of the motherboard must be flush with the rear of the server. Additionally, the four holes in the motherboard must align with the four holes in the bus bars.
