Hardware Setup
Preparing the Hardware Installation
To access some components and perform certain service
procedures, you must perform the following procedures
first.
WARNING: To reduce the risk of personal injury,
electric shock, or damage to the equipment,
remove the power cord to remove power from
the server. The power switch button does not
completely shut off system power. Portions of the
power supply and some internal circuitry remain
active until power is removed.
Unpower the LEC-7920 and remove the power cord.1.
Turn the device upside down.2.
Unscrew the 4 rubber feet from the bottom cover.3.
Open the cover.4.
Installing the System Memory
The motherboard supports DDR3 memory to meet the
higher bandwidth requirements of the latest operating
system and Internet applications. It comes with two
Double Data Rate Three (DDR3) Small Outline Dual Inline
Memory Module (SO-DIMM) socket.
Align the memory module’s cutout with the SO-DIMM1.
socket’s notch.
Install the SO-DIMM.2.
Note:
The system can support memory of DDR3 SO-
DIMM up to 8 GB in maximum.
Installing the CPU
The system supports Intel CPU i5, i7 and Celeron P4500
processor which should be installed on the motherboard’s
micro-PGA 989 socket.
To install the CPU to the socket, follow these steps:
Align the CPU’s triangle with the socket’s triangle.1.
