A+ SERVER 2021TM-BTRF/BIBXRF User's Manual
Front Control Panel
SC827 models include four front panels on the handles of the chassis which control
each of the systems. Each control panel on the A+ Server 2021TM-BTRF/BIBXRF
provides you with system monitoring and control for one server node. LEDs indicate
system power, HDD activity, network activity, system overheat and power supply
failure. A main power button and a system reset button are also included.
I/O Backplane
The SC827 is an ATX form factor chassis designed to be used in a 2U rackmount
configuration. The SAS827B I/O backplane provides a low-profile add-on card
slot, a COM port, a VGA port, two USB 2.0 ports and two gigabit Ethernet ports
per node.
For more information regarding the backplane, view the appendices found at the
end of this manual.
Cooling System
The SC827 chassis accepts four system fans powered from either backpane or the
serverboards. If not powered from the backpane, the SC827B model chassis powers
two fans from two motherboards, so that when one of the motherboard drawers is
removed, the second motherboard will continue running both fans.
Air Shrouds
The SC827 chassis includes four mylar air shrouds that direct the airflow where
cooling is needed on each serverboard. Always use the air shroud included with
your chassis on each serverboard.
Mounting Rails
The SC827 includes a set of quick-release rails, and can be placed in a rack for
secure storage and use. To setup your rack, follow the step-by-step instructions
included in this manual.

Chapter 1: Introduction
1-5 2U Twin2: System Notes
As a 2U Twin2configuration, the 2021TM-BTRF/BIBXRF 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
Asingle 1200W 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
1200W power supply module for power redundancy.
SATA Backplane/Drives
As a system, the 2021TM-BTRF/BIBXRF 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.

2-1 Overview
This chapter provides a quick setup checklist to get your A+ Server 2021TM-BTRF/
BIBXRF 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 2021TM-BTRF/BIBXRF 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 2021TM-
BTRF/BIBXRF. 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 2021TM-BTRF/BIBXRF 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.
