Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your SuperServer 6026T-TF 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 SuperServer 6026T-TF system has come to you with the processors and
memory preinstalled. If your system is not already fully integrated with a motherboard, processors, system memory etc., please turn to the chapter or section noted
in each step for details on installing specifi c components.
2-2 Unpacking the System
You should inspect the box the SuperServer 6026T-TF was shipped in and note
if it was damaged in any way. If the server itself shows damage you should fi le a
damage claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the SuperServer 6026TTF. It should be situated in a clean, dust-free area that is well ventilated. Avoid
areas where heat, electrical noise and electromagnetic fi elds 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 SuperServer 6026T-TF 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
2-1
SUPERSERVER 6026T-TF Manual
!
!
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 suffi cient airfl ow and ease in servicing.
This product is for installation only in a Restricted Access Location (dedicated
•
equipment rooms, service closets and the like).
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.
Warnings and Precautions!
Rack Precautions
Ensure that the leveling jacks on the bottom of the rack are fully extended to •
the fl oor 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 fi rst, 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.
2-2
Chapter 2: Server Installation
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.
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 Airfl ow
Equipment should be mounted into a rack so that the amount of airfl 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.).

SUPERSERVER 6026T-TF Manual
2-4 Installing the System into a Rack
This section provides information on installing the SuperServer 6026T-TF into a rack
unit. If the 6026T-TF has already been mounted into a rack, you can skip ahead to
Sections 2-5 and 2-6. There are a variety of rack units on the market, which may
mean the assembly procedure will differ slightly. The following is a guideline for
installing the 6026T-TF into a rack with the rack rails provided. You should also refer
to the installation instructions that came with the rack unit you are using.
Identifying the Sections of the Rack Rails
You should have received two rack rail assemblies with the SuperServer 6026T-TF.
Each of these assemblies consist of three sections: an inner fi xed chassis rail that
secures to the 6026T-TF (A) and an outer fi xed rack rail that secures directly to
the rack itself (B). A sliding rail guide sandwiched between the two should remain
attached to the fi xed rack rail (see Figure 2-1). The A and B rails must be detached
from each other to install.
To remove the fi xed chassis rail (A), pull it out as far as possible - you should hear
a "click" sound as a locking tab emerges from inside the rail assembly and locks
the inner rail. Then depress the locking tab to pull the inner rail completely out. Do
this for both the left and right side rack rail assemblies.
Figure 2-1. Identifying the Sections of the Rack Rails
B
A
2-4
Chapter 2: Server Installation
Installing the Chassis Rails
Position one of the fi xed chassis rail sections you just removed along the side of the
6026T-TF. Note that these two rails are left/right specifi c. Slide the rail toward the
front of the chassis (see arrows in Figure 2-2) until you hear them click into place
with the retention hooks on the chassis. The screw holes should now be aligned screw the rail securely to the side of the chassis (see Figure 2-2).
Repeat this procedure for the other rail on the other side of the chassis. You will
also need to attach the rail brackets when installng into a telco rack.
Locking Tabs: As you have seen, both chassis rails have a locking tab, which
serves two functions. The fi rst is to lock the server into place when installed and
pushed fully into the rack, which is its normal position. Secondly, these tabs also
lock the server in place when fully extended from the rack. This prevents the server
from coming completely out of the rack when you pull it out for servicing.
Figure 2-2. Installing Chassis Rails
Installing the Rack Rails
Determine where you want to place the SuperServer 6026T-TF in the rack. (See
Rack and Server Precautions in Section 2-3.) Position the fi xed rack rail/sliding rail
guide assemblies at the desired location in the rack, keeping the sliding rail guide
facing the inside of the rack. Screw the assembly securely to the rack using the
brackets provided. Attach the other assembly to the other side of the rack, making
sure both are at the exact same height and with the rail guides facing inward.
2-5
SUPERSERVER 6026T-TF Manual
Installing the Server into the Rack
You should now have rails attached to both the chassis and the rack unit. The next
step is to install the server into the rack. Do this by lining up the rear of the chassis
rails with the front of the rack rails. Slide the chassis rails into the rack rails, keeping
the pressure even on both sides (you may have to depress the locking tabs when
inserting). See Figure 2-3.
When the server has been pushed completely into the rack, you should hear the
locking tabs "click". Finish by inserting and tightening the thumbscrews that hold
the front of the server to the rack.

Chapter 2: Server Installation
Installing the Server into a Telco Rack
If you are installing the SuperServer 6026T-TF into a Telco type rack, follow the
directions given on the previous pages for rack installation. The only difference in the
installation procedure will be the positioning of the rack brackets to the rack. They
should be spaced apart just enough to accommodate the width of the telco rack.

SUPERSERVER 6026T-TF Manual
2-5 Checking the Motherboard Setup
After you install the 6026T-TF in the rack, you will need to open the unit to make sure
the motherboard is properly installed and all the connections have been made.
Accessing the Inside of the System (see Figure 2-5)
Grasp the two handles on either side and pull the unit straight out until it 1.
locks (you will hear a "click").
Next, depress the two buttons on the top of the chassis to release the top 2.
cover. There is a large rectangular recess in the middle front of the top cover
to help you push the cover away from you until it stops.
Lift the top cover from the chassis to gain full access to the inside of the 3.
server.
Checking the Components and Setup
You may have one or two processors already installed into the serverboard. 1.
Each processor needs its own heat sink. See Chapter 5 for instructions on
processor and heat sink installation.
Your server may have come with system memory already installed. Make 2.
sure all DIMMs are fully seated in their slots. For details on adding system
memory, refer to Chapter 5.
If desired, you can install add-on cards to the system. See Chapter 5 for 3.
details on installing PCI add-on cards.
Make sure all power and data cables are properly connected and not blocking 4.
the chassis airfl ow. Also make sure that no cables are positioned in front of
the fans. See Chapter 5 for details on cable connections.

2-6 Checking the Drive Bay Setup
Next, you should check to make sure the peripheral drives and the SATA drives
have been properly installed and all connections have been made.
Checking the Drives
All drives are accessable from the front of the server. For servicing the DVD-1.
ROM, you will need to remove the top chassis cover. The hard drives can be
installed and removed from the front of the chassis without removing the top
chassis cover.
A slim DVD-ROM may be preinstalled in your server. Refer to Chapter 6 if 2.
you need to install a DVD-ROM drive to the system.
Depending upon your system's confi guration, your system may have one or 3.
more drives already installed. If you need to install hard drives, please refer to
Chapter 6.
Checking the Airfl ow
Airfl ow is provided by four hot-swappable 8-cm chassis cooling fans. The 1.
system component layout was carefully designed to direct suffi cient cooling
airfl ow to the components that generate the most heat.
Note that all power and data cables have been routed in such a way that they 2.
do not block the airfl ow generated by the fans.
Providing Power
Plug the power cord(s) from the power supply unit(s) into a high-quality power 1.
strip that offers protection from electrical noise and power surges. It is recommended that you use an uninterruptible power supply (UPS).

System Safety
4-1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SuperServer 6026T-TF from damage:
Be aware of the locations of the power on/off switch on the chassis as well
•
as the room's emergency power-off switch, disconnection switch or electrical
outlet. If an electrical accident occurs, you can then quickly remove power from
the system.
Do not work alone when working with high voltage components.
•
Power should always be disconnected from the system when removing or install-•
ing main system components, such as the serverboard, memory modules and
fl oppy drive. When disconnecting power, you should fi rst power down the system
with the operating system. The unit may have more than one power supply cord.
Disconnect both power supply cords before servicing to avoid electrical shock.
When working around exposed electrical circuits, another person who is familiar
•
with the power-off controls should be nearby to switch off the power if necessary.
Use only one hand when working with powered-on electrical equipment. This
•
is to avoid making a complete circuit, which will cause electrical shock. Use
extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
Do not use mats designed to decrease static electrical discharge as protection
•
from electrical shock. Instead, use rubber mats that have been specifi cally
designed as electrical insulators.
The power supply power cords must include a grounding plug and must be
•
plugged into grounded electrical outlets.
