1-2 Serverboard Features
At the heart of the SuperServer 2027GR-TSF/2027GR-TRF/2027GR-TRFT is the
X9DRG-HF/X9DRG-HTF, a dual processor serverboard based on the Intel C602
chipset. Below are the main features of the X9DRG-HF/X9DRG-HTF. (See Figure
1-1 for a block diagram of the chipset).
Processors
The X9DRG-HF/X9DRG-HTF supports two Intel Xeon E5-2600 series processors in
LGA 2011 sockets (Socket R). Please refer to the serverboard description pages on
our web site for a complete listing of supported processors (www.supermicro.com).
Memory
The X9DRG-HF/X9DRG-HTF has eight DIMM slots that can support up to 256 GB
of registered ECC DDR3-1600/1333/1066/800 MHz RDIMMs. Modules of the same
size and speed are recommended. See Chapter 5 for details.
Serial ATA
A SATA controller is integrated into the chipset to provide a 10-port SATA subsystem,
which is RAID 0, 1, 5 and 10 supported. Two of these are SATA 3.0 ports and eight
are SATA 2.0 ports. The SATA drives are hot-swappable units.
Note: The operating system you use must have RAID support to enable the
hot-swap capability and RAID function of the SATA drives. One RAID level may
be applied to HDDs 0-3 and one RAID level may be applied to HDDs 4-7. See
Section 6-4 for details.

The X9DRG-HF/X9DRG-HTF has four PCI-Express 3.0 x16 slots to support four
double-width GPU cards. Additional slots support one PCI-Express 3.0 x8 low-profile
card and one PCI-E 2.0 x4 standard card.
Onboard Controllers/Ports
The color-coded I/O ports include one COM port (an additional COM header is lo-
cated on the serverboard), a VGA (monitor) port, two USB 2.0 ports, two Gb Ethernet
LAN ports (two 10 Gb ports on the X9DRG-HTF) and one dedicated IPMI LAN port.

1-3
Chapter 1: Introduction
IPMI
IPMI (Intelligent Platform Management Interface) is a hardware-level interface speci-
fication that provides remote access, monitoring and administration for Supermicro
server platforms. IPMI allows server administrators to view a server’s hardware
status remotely, receive an alarm automatically if a failure occurs, and power cycle
a system that is non-responsive.
1-3 Server Chassis Features
System Power
The SC218G-R1800B features a high-efficiency, redundant 1800W power supply
composed of two separate power modules. This power redundancy feature allows
you to replace a failed power supply without shutting down the system. See Chapter
6 for details. Note: the 2027GR-TSF includes a single power supply only.
SATA Subsystem
The SC218G-R1800B chassis includes ten 2.5" drive bays, which may be used to
house hot-swap SATA drives. RAID 0, 1, 5 and 10 are supported.
To provide power for the backplane, connect the JPW5 header on the serverboard
to both 4-pin connectors on the backplane using CBL-0460L.
Front Control Panel
The control panel provides a system monitoring and control interface. LEDs indicate
system power, HDD activity, network activity, and a system overheat/fan fail/ UID
LED. A main power button and a system reset button are also included.
Cooling System
The SC218G-R1800B has an innovative cooling design that includes five 8-cm
heavy-duty fans. The power supply modules also include a cooling fan. All chassis
and power supply fans operate continuously.

Chapter 2: Server Installation
2-1
Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your system up and running.
Following these steps in the order given should enable you to have the system
operational within a minimum amount of time. This quick setup assumes that your
system has come to you with the processors and memory preinstalled. If your sys-
tem is not already fully integrated with a serverboard, processors, system memory
etc., please turn to the chapter or section noted in each step for details on installing
specific components.
2-2 Unpacking the System
You should inspect the box the system was shipped in and note if it was damaged
in any way. If the server itself shows damage you should file a damage claim with
the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the server. It should
be situated in a clean, dust-free area that is well ventilated. Avoid areas where
heat, electrical noise and electromagnetic fields are generated. You will also need
it placed near a grounded power outlet. Read the Rack and Server Precautions in
the next section.
2-3 Preparing for Setup
The box the server was shipped in should include two sets of rail assemblies, two
rail mounting brackets and the mounting screws you will need to install the system
into the rack. Follow the steps in the order given to complete the installation process
in a minimum amount of time. Please read this section in its entirety before you
begin the installation procedure outlined in the sections that follow.
Choosing a Setup Location
• Leave enough clearance in front of the rack to enable you to open the front door
completely (~25 inches) and approximately 30 inches of clearance in the back
of the rack to allow for sufficient airflow and ease in servicing.This product is for
installation only in a Restricted Access Location (dedicated equipment rooms,
service closets and the like).

2-2
SUPERSERVER 2027GR-TSF/2027GR-TRF/2027GR-TRFT User's Manual
• This product is not suitable for use with visual display work place devices
acccording to §2 of the the German Ordinance for Work with Visual Display Units.
2-4 Warnings and Precautions
Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to
the floor with the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack. In multiple
rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component from the
rack.
• You should extend only one component at a time - extending two or more si-
multaneously may cause the rack to become unstable.
• Rack-mounted equipment should not be used as a shelf or work space.
Server Precautions
• Review the electrical and general safety precautions in Chapter 4.
• Determine the placement of each component in the rack before you install the
rails.
• Install the heaviest server components on the bottom of the rack first, and then
work up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from
power surges, voltage spikes and to keep your system operating in case of a
power failure.
• Allow the hot plug SATA drives and power supply modules to cool before touch-
ing them.
• Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.

Chapter 2: Server Installation
2-3
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture of the rack environment may be greater than the ambient temperature of the
room. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated ambient tempera-
ture (Tmra).
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required
for safe operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).
Warning! To prevent bodily injury when mounting or servicing this unit in a
rack, you must take special precautions to ensure that the system remains
stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.

2-5 Installing the System into a Rack
This section provides information on installing the chassis into a rack unit with the
rails provided. There are a variety of rack units on the market, which may mean
that the assembly procedure will differ slightly from the instructions provided. You
should also refer to the installation instructions that came with the rack unit you are
using. Note: This rail will fit a rack between 26.5" and 36.4" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of three sections: an inner chassis rail that secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail that extends
from the outer rail. These assemblies are left/right specific.

Locking Tabs
Each inner rail has a locking tab. This tab locks the chassis into place when installed
and pushed fully into the rack. These tabs also lock the chassis in place when fully
extended from the rack. This prevents the server from coming completely out of
the rack when when the chassis is pulled out for servicing.
Releasing the Inner Rail
