1-3 Server Chassis Features
The following is a general outline of the main features of the SC827HD-R1400B 2U
chassis. Details on the chassis can be found in Chapter 6.
System Power
When configured as a SuperServer 6026TT-HD/D6 series server, the SC827HD-
R1400B includes a redundant (dual) 1400W power supply, which provides power
to all four serverboards (nodes). If either power supply failes, the other will allow
the system to continue to run.
SATA Subsystem
The SC827HD-R1400B chassis was designed to support twelve SATA hard
drives, which are hot-swappable units. There are six hard drives per node in the
system.
Control Panel
The SC827HD-R1400B features two independant control panels associated with
each serverboard (node) in the chassis. Each control panel has LEDs to indicate
power on, network activity, power fail, fan fail, system overheat conditions and the
UID LED. Each control panel also includes a main power button and a UID but-
ton.
Rear I/O Panel
The SC827HD-R1400B is a 2U rackmount chassis. The rear of the chassis provides
slots for four full-height, full-length PCI Express x8 expansion cards (in x16 slots),
two COM ports, four USB ports, two VGA ports and four Gb Ethernet ports. See
Chapter 6 for details.
Cooling System
The SC827HD-R1400B chassis has an innovative cooling design that features four
8-cm high-performance fans. A fan speed control setting in BIOS allows fan speed
to be determined by system temperature. See Chapter 6 for details.

SUPERSERVER 6026TT-HD/D6 Series User's Manual
1-4 2U Twin: System Notes
As a 2U Twin configuration, the 6026TT-HD/D6 series is a unique server system.
With two system boards incorporated into a single chassis acting as two separate
nodes, there are several points you should keep in mind.
Nodes
Each of the two 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.
System Power
The server has an additional 1400W power supply module (two total) for power
redundancy. If a power supply module fails the other backup module will keep the
system running until it can be replaced.
Backplane/Drives
As a system, the 6026TT-HDx and 6026TT-D6x servers supports the use of twelve
SATAand SAS drives, respectively.Asingle backplane works to apply system-based
control for power and fan speed functions, yet at the same time logically connects
a set of six SATA drives to each serverboard. Consequently, RAID setup is limited
to a six-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 the system up and running. Fol-
lowing these steps in the order given should enable you to have the system opera-
tional 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, memory etc., please
turn to the chapter 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. Be sure to read the Rack and Server Precautions
in the next section.
2-3 Preparing for Setup
The server should include the rackmount hardware needed 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).
• Leave 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 6026TT-HD/D6 Series User's Manual
• This product is not suitable for use with visual display work place devices ac-
cording 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 it.
• 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 the hard 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.
• Make sure all power and data cables are properly connected and not blocking
the chassis airflow. See Chapter 5 for details on cable connections.

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.

SUPERSERVER 6026TT-HD/D6 Series User's Manual
Warning: Except for short periods of time, do NOT operate the server without the
cover in place. The chassis cover must be in place to allow proper airflow and prevent
overheating.
Removing the Protective Film
Before operating the server for the first time, it is important to remove the protec-
tive film covering the top of the chassis, in order to allow for proper ventilation and
cooling.
Removing the Protective Film
1. Peel off the protective film covering the top cover and the top of the chassis
2. Check that all ventilation openings on the top cover and the top of the chassis
are clear and unobstructed.
