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.
1. Make sure the server is powered off.
Power down the server if it is still running.
(1) Press the Power button to power off the server from full-power mode to standbypower (sleep) mode. The Power LED at the front turns from solid green to blinking
green.
(2) Disconnect the power cord first from the AC outlet and then from the server.
The power LED turns off.
The server is not completely powered down when you press the Power button on the front
panel. The Power button lets the server toggle between Power On and Standby (Sleep)
modes. Some internal circuitry remain active in the Standby mode. To remove all power
from the system completely, be sure to disconnect the power cord from the server.
2. Ensure you have a clean and stable working environment. Avoid dust and dirt because
contaminants may cause malfunctions.
3. Ground yourself properly before touching any system component. A discharge of static
electricity may damage components. Wear a grounded wrist strap if available.

3.3 Power Supply
Installing and Removing the Power Supply
Before replacing the power supply, power off the server, unplug the power cord, and disconnect all wiring from the power supply.
Installing the Power Supply Unit
The 3U8G Series can accommodate four AC or two DC power supplies in the bay at the
rear of the chassis. Each unit provides up to 1200 Watts (200V AC) or 1000 Watts (100V
AC) of power. Three power supplies are required for full load operation, with the fourth
power supply purely as a redundant, load-sharing backup. It can be removed without
affecting system operation.
1. Align the power supply unit with the power supply slot. Ensure that the LED appears
on the lower right when you are installing the power supply unit.
2. Carefully slide the PSU all the way into the power supply bay until it clicks into place.

The 3U8G series chassis supports hot-swappable system fans.
Replacing the System Fan
1. Remove the top middle cover from the chassis. (See p. 14 for more details.)
2. Lift to remove the failed fan.
3. Align the mounting holes on the replacement fan corners with the fan mounts on the
fan bracket. Make sure the arrow on the fan pointed to the REAR of the chassis.
4. Gently place the fan onto the mounts. Make sure the fan is well seated.
English
22
3U8G Series
Reversing the Fan Modules (only required for active GPGPU users)
If you are using "active" GPGPU cards that are equipped with one or more fans on
the cards, the system requires back-to-front air flow routing, so you need to reverse
the fan modules before installing the system fans.
*A front-to-back airflow for active cards may also be possible and can be defined by customers after
validation (when operation temperature is under 25°C).

Connect one end (B) of the GPGPU Power Cable to the connector on the switchboard
(SWB). Then, connect the other ends (A) to the back of the GPU/MIC card or on the
side of the card.
If the power connectors of the GPGPU card you use are on the top side, the connectors and
the connected cable will extend the height of the card; thus, you will need a 4U top (front)
cover. Please purchase separately if needed. To know how to install top covers, please refer
to “3.1 Server Top Cover - Installing the Server Top Covers“.

Attaching the Slide Rail Assemblies to the Rack
Determine where to attach the slide rails. Make sure you have enough free space
above the slide rail bracket for the chassis.
*For a 3U server, 6 holes of free space above the slide rail bracket are required. If you use a 4U top cover for
the server, you need to have 9 holes of free space above the slide rail bracket.
For the rack with square mounting holes, insert cage nuts in the holes that you will
use on the rack.
