1U2E Series Chapter 3 Hardware Installation and Maintenance This chapter helps you assemble the chassis and install components. Before You Begin Before you work with the server, pay close attention to the “Important Safety Instructions” at the beginning of this manual.
3.1 Server Top Cover Removing the Server Top Cover 1. Before removing the top cover, power off the server and unplug the power cord. 2. The system must be operated with the chassis top cover installed to ensure proper cooling. 1.
Page 17
1U2E Series Installing the Server Top Cover 1. Lower the top cover on the chassis, making sure the side latches align with the cutouts. 2. Slide the top cover toward the front. 3. Secure the top cover with the screws.
3.2 3.5” Hard Drive Removing a 3.5” Hard Drive Carrier from the Chassis 1. Release the screws that secure the hard drive carrier to the chassis. 2. Lift up and remove the carrier.
Page 19
1U2E Series Installing a 3.5” Hard Drive to the Hard Drive Carrier 1. Place the 3.5" HDD into the carrier with the printed circuit board side facing down. Carefully align the mounting holes in the hard drive and the carrier.
3.3 2.5” Hard Drive The system supports 2.5" hard drives. Two 2.5" hard drive trays are located on the front of the system. Removing 2.5” Hard Drive Trays from the Chassis 1. Press the locking lever latch on the drive tray to unlock the retention lever. 2.

1U2E Series Installing a 2.5” Hard Drive to the Hard Drive Tray 1. Place a 2.5" HDD into the bracket with the printed circuit board side facing down. 2. Slide the drive tray into the HDD bay until the drive is fully seated.
3.4 System Fan System fans are required for the cooling in the system. Please make sure that the chassis top cover is properly installed in order for the cooling air to circulate properly through the chassis and cool the system and components. If a fan fails, the ambient air temperature in the chassis will rise.
1U2E Series 3.5 Power Supply This system has a single 315 watt power supply and can accommodate one AC power supply in the bay at the rear of the chassis. If the power supply unit fails, the system will shut down and you will need to replace the power supply unit.
3.6 Slim Optical Drive (optional) Removing the Optical Drive Carrier and the Blanking Plate from the Chassis 1. Release the screws that secure the optical drive carrier to the chassis. 2. Lift up and remove the carrier.

Installing an Optical Drive to the Chassis To use a slim optical drive, you need to purchase a rear SATA/Power adapter seperately. Before installation, secure the rear adapter to the bare drive with screws. Place the slim optical drive into the carrier with the connector end toward the rear side of the carrier where the mounting holes are located.

1U2E Series Place the optical drive assembly back to the chassis with screw holes aligned. Secure the ptical drive assembly to the chassis with two screws.
Appendix A Installing the CPU (LGA 1200 Socket) 1. Before you insert the 1200-Pin CPU into the socket, please check if the PnP cap is on the socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to insert the CPU into the socket if above situation is found.
Page 29
1U2E Series Please save and replace the cover if the processor is removed. The cover must be placed if you wish to return the motherboard for after service.
1U2E Series Installing the CPU Fan and Heatsink (AMD AM4 Socket) After you install the CPU into this motherboard, it is necessary to install a larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU and the heatsink to improve heat dissipation.
Page 36
Appendix B Installation of Memory Modules (DIMM) The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation. For more information about DIMM installation, please refer to the User Manual that comes with the serverboard you use.
