Chapter 1: Introduction
1-5 2U Twin2: System Notes
As a 2U Twin2configuration, the 2022TG-HTRF/HIBQRF is a unique server system.
With four system boards incorporated into a single chassis acting as four separate
nodes, there are several points you should keep in mind.
Nodes
Each of the four serverboards act as a separate node in the system.As independant
nodes, each may be powered off and on without affecting the others. In addition,
each node is a hot-swappable unit that may be removed from the rear of the chassis.
The nodes are connected to the server backplane by means of an adapter card.
Note:Aguide pin is located between the upper and lower nodes on the inner chassis
wall. This guide pin also acts as a “stop” when a node is fully installed. If too much
force is used when inserting a node this pin may break off. Take care to slowly slide
a node in until you hear the “click” of the locking tab seating itself.
System Power
Asingle 1400W power supply is used to provide the power for all four serverboards.
Each serverboard however, can be shut down independently of the other with the
power button on its own control panel. As an option, you may add an additional
1400W power supply module for power redundancy.
SATA Backplane/Drives
As a system, the 2022TG-HTRF/HIBQRF supports the use of twelve SATA drives.
A single SATA backplane works to apply system-based control for power and fan
speed functions, yet at the same time logically connects a set of three SATA drives
to each serverboard. Consequently, RAID setup is limited to a three-drive scheme
(RAID cannot be spread across all twelve drives). See the Drive Bay Installation/
Removal section in Chapter 6 for the logical hard drive and node configuration.

Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your A+ SERVER
2022TG-HTRF/HIBQRF 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 system 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 A+ SERVER 2022TG-HTRF/HIBQRF 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 A+ SERVER
2022TG-HTRF/HIBQRF. 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 A+ SERVER 2022TG-HTRF/HIBQRF 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.

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.
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 any hot plug drives and power supply modules to cool before touching•
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
temperature 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
temperature (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
connections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).

A+ SERVER 2022TG-HTRF/HIBQRF User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the SC827 chassis into a rack unit
with the quick-release rails provided. There are a variety of rack units on the market,
which may mean the assembly procedure will differ slightly. 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" and 33.5" deep.
Separating the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of two sections: an inner fixed chassis rail that secures directly
to the server chassis and an outer fixed rack rail that secures directly to the rack
itself.
