This chapter provides a quick setup checklist to get your 2026T-6RFT+/6RF+ 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 pre-installed. 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 specifi c components.
2-2 Unpacking the System
You should inspect the box the 2026T-6RFT+/6RF+ was shipped in and note if it
was damaged in any way. If the server itself shows damage you should fi le a dam-
age claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold the 2026T-6RFT+/6RF+.
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. Be sure to read the Rack and Server
Precautions in the next section.
2-3 Preparing for Setup
The box the 2026T-6RFT+/6RF+ 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 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).
2-1
SUPERSERVER 2026T-6RFT+/6RF+ User's Manual
• 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.
2-4 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.
• Allow the hot plug SAS/SATA 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.
2-2
Chapter 2: Server Installation
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.).
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 fi 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.

2-5 Installing the System into a Rack
This section provides information on installing the 2026T-6RFT+/6RF+ into a rack
unit with the rack 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.
Identifying the Sections of the Rack Rails
You should have received two rack rail assemblies in the rack mounting kit. Each
assembly consists of two sections: an inner fi xed chassis rail that secures directly
to the chassis and an outer rack rail that secures directly to the rack itself.
Locking Tabs
Both inner chassis rails have a locking tab. The tabs lock the chassis into place
when installed and pushed fully into the rack. 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.
