Chapter 2 Installation
is is an Micro-STX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
Make sure to unplug the power cord before installing or removing the motherboard
•
components. Failure to do so may cause physical injuries and damages to motherboard
components.
In order to avoid damage from static electricity to the motherboard’s components,
•
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
•
in the bag that comes with the components.
When placing screws to secure the motherboard to the chassis, please do not over-
•
tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1151-Pin CPU into the socket, please check if the P nP cap is on the
socket, if the CPU surface is unclean, or if there are any bent pins in the sock et. Do not
force to in sert the CPU into the socket if above situation is found . Otherwise, the CPU
will be seriously damaged.
2. Unplug all power c ables before in stalling the CPU.
