1-4 2U Twin2: System Notes
As a 2U Twin2 conguration, the 2022TG-H6IBQRF/H6RF 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: A guide 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
A single 1620 Watts power supply can be 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 a default, the
2022TG-H6IBQRF/H6RF comes with a second power supply module for power
redundancy.
Note: Depending on the input power and certain workloads, conguration power
supply redundancy may not always be available.
SAS/SATA Backplane/Drives
As a system, the 2022TG-H6IBQRF/H6RF supports the use of twelve SAS 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 SAS 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 conguration.

•When mounting this unit in a partially lled 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.
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 Airow
Equipment should be mounted into a rack so that the amount of airow 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.).

2-5 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 your rack unit.
NOTE: This rail will t a rack between 26" and 33.5" 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 which secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail which extends
from the outer rail (see Figure 2-1). These assemblies are specically designed for
the left and right side of the chassis.

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 the chassis is pulled out for servicing.
