CHAPTER 2: HARDWARE INSTALLATION
2.1 Install Central Processing Unit (CPU)
Step 1: Locate the CPU socket on the motherboard

Note1: Remove Pin Cap before installation, and make good preservation for future use. When the CPU is removed, cover the Pin Cap on the empty socket to ensure pin legs won't be damaged. Note2: The motherboard might equip with two different types of pin cap. Please refer below instruction to remove the pin cap.
Step 2: Pull the socket locking lever out from the socket and then raise the lever up.


Step 3: Remove the Pin Cap.


Motherboard Manual
Step 4: Hold processor with your thumb and index fingers, oriented as shown. Align the notches with the socket. Lower the processor straight down without tilting or sliding the processor in the socket.

Note1: The LGA1155 CPU is not compatible with LGA 1150 socket. Do not install a LGA 1155 CPU on the LGA 1150 socket.
Note2: The CPU fits only in one correct orientation. Do not force the CPU into the socket to prevent damaging the CPU.
Step 5: Hold the CPU down firmly, and then lower the lever to locked position to complete the installation.

2.2 Install a Heatsink

4.4 Troubleshooting
| Probable | Solution |
| 1. There is no power in the system. Power LED does not shine; the fan of the power supply does not work2. Indicator light on keyboard does not shine. | 1. Make sure power cable is securely plugged in.2. Replace cable.3. Contact technical support. |
| System is inoperative. Keyboard lights are on, power indicator lights are lit, and hard drives are running. | Using even pressure on both ends of the DIMM, press down firmly until the module snaps into place. |
| System does not boot from a hard disk drive, but can be booted from optical drive. | 1. Check cable running from disk to disk controller board. Make sure both ends are securely plugged in; check the drive type in the standard CMOS setup.2. Backing up the hard drive is extremely important. All hard disks are capable of breaking down at any time. |
| System only boots from an optical drive. Hard disks can be read, applications can be used, but system fails to boot from a hard disk. | 1. Back up data and applications files.2. Reformat the hard drive. Re-install applications and data using backup disks. |
| Screen message shows “Invalid Configuration” or “CMOS Failure.” | Review system’s equipment. Make sure correct information is in setup. |
| System cannot boot after user installs a second hard drive. | 1. Set master/slave jumpers correctly.2. Run SETUP program and select correct drive types. Call the drive manufacturers for compatibility with other drives. |
CPU Overheated
If the system shutdown automatically after power on system for seconds, that means the CPU protection function has been activated.
When the CPU is over heated, the motherboard will shutdown automatically to avoid a damage of the CPU, and the system may not power on again.
In this case, please double check:
- The CPU cooler surface is placed evenly with the CPU surface.
- CPU fan is rotated normally.
- CPU fan speed is fulfilling with the CPU speed.
After confirmed, please follow steps below to relief the CPU protection function.
- Remove the power cord from power supply for seconds.
- Wait for seconds.
- Plug in the power cord and boot up the system.
Or you can:
- Clear the CMOS data.
- Wait for seconds.
- Power on the system again.
4.5 RAID Functions
RAID Definitions
RAID 0:
![graph TD A["RAID 0 striping"] --> B["Block 1"] A --> C["Block 2"] A --> D["Block 3"] A --> E["Block 4"] A --> F["Block 5"] A --> G["Disk 1"] A --> H["Disk 2"]](/content/2026/05/1067897/images/222b93846605c044eb4903b17751fcb992a4929513e5b286fb25b92cf9baadc3.jpg)
In a RAID 0 system data are split up in blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, this offers superior I/O performance. This performance can be enhanced further by using multiple controllers, ideally one controller per disk.
Features and Benefits
- Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the platform.
- Uses: Intended for non-critical data requiring high data throughput, or any environment that does not require fault tolerance.
- Benefits: provides increased data throughput, especially for large files. No capacity loss penalty for parity.
- Drawbacks: Does not deliver any fault tolerance. If any drive in the array fails, all data is lost.
- Fault Tolerance: No.
- Total Capacity: (Minimal. HDD Capacity) x (Connected HDDs Amount)
RAID 1:
![graph TD A["Block 1"] --> B["Block 2"] B --> C["Block 3"] D["Block 1"] --> E["Block 2"] E --> F["Block 3"] G["Disk 1"] --> H["Disk 2"] I["RAID 1 mirroring"] --> J["Block 1"] I --> K["Block 2"] I --> L["Block 3"]](/content/2026/05/1067897/images/d2189f0aaa52d90e44d46c8421e4dd022edacbaa790def6ee95e5cc8d45a8688.jpg)
Data are stored twice by writing them to both the data disk (or set of data disks) and a mirror disk (or set of disks). If a disk fails, the controller uses either the data drive or the mirror drive for data recovery and continues operation. You need at least 2 disks for a RAID 1 array.
Features and Benefits
- Drives: Minimum 2, and maximum is 2.
- Uses: RAID 1 is ideal for small databases or any other application that requires fault tolerance and minimal capacity.
- Benefits: Provides 100% data redundancy. Should one drive fail, the controller switches to the other drive.
- Drawbacks: Requires 2 drives for the storage space of one drive. Performance is impaired during drive rebuilds.
- Fault Tolerance: Yes.
RAID 10:
![graph TD A["RAID 10 (1+0)"] --> B["Block 1"] A --> C["Block 2"] A --> D["Block 3"] A --> E["Block 4"] A --> F["Block 5"] B --> G["Disk 1"] C --> H["Disk 2"] D --> I["Disk 3"] E --> J["Disk 4"] F --> K["Disk 5"]](/content/2026/05/1067897/images/69fcd76bba301f7f2c6140a0b7a56f74eb7ddf30c7870493c4719a7c2f7446f8.jpg)
RAID 10 combines the advantages (and disadvantages) of RAID 0 and RAID 1 in one single system. It provides security by mirroring all data on a secondary set of disks (disk 3 and 4 in the drawing below) while using striping across each set of disks to speed up data transfers.
Features and Benefits
- Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
- Benefits: Optimizes for both fault tolerance and performance, allowing for automatic redundancy. May be simultaneously used with other RAID levels in an array, and allows for spare disks.
- Drawbacks: Requires twice the available disk space for data redundancy, the same as RAID level 1.
- Fault Tolerance: Yes.
RAID 5:
![graph TD A["RAID 5"] --> B["parity across disks"] B --> C["Disk 1"] B --> D["Disk 2"] B --> E["Disk 3"] C --> F["DATA1"] C --> G["DATA2"] C --> H["PARITY"] D --> I["DATA3"] D --> J["PARITY"] D --> K["DATA4"] D --> L["PARITY"] D --> M["DATA5"] D --> N["DATA6"] D --> O["PARITY"] D --> P["PARITY"] D --…](/content/2026/05/1067897/images/3107354b64549f2eb885a181e99839c67c03aa3590f6c47a618bc87f557f9200.jpg)
A RAID 5 array can withstand a single disk failure without losing data or access to data. Although RAID 5 can be achieved in software, a hardware controller is recommended. Often extra cache memory is used on these controllers to improve the write performance.
Features and Benefits
- Drives: Minimum 3.
- Uses: RAID 5 is recommended for transaction processing and general purpose service.
- Benefits: An ideal combination of good performance, good fault tolerance, and high capacity and storage efficiency.
- Drawbacks: Individual block data transfer rate same as a single disk. Write performance can be CPU intensive.
- Fault Tolerance: Yes.
Note1: The RAID 0,1,10 and 5 functions are only supported by Z87 & H87 chipsets.
