This chapter provides a quick setup checklist to get your SuperServer 1026TURF/1026T-UF 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 server 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 specifi c components.
2-2 Unpacking the System
You should inspect the box the SuperServer 1026T-URF/1026T-UF 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 server. 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 1026T-URF/1026T-UF 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
2-1
SUPERSERVER 1026T-URF/1026T-UF User's Manual
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.
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 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.
Installing the Server into a Telco Rack
To install the SuperServer 1026T-URF/1026T-UF into a Telco type rack, use two
L-shaped brackets on either side of the chassis (four total). First, determine how
far follow the server will extend out the front of the rack. Larger chassis should be
positioned to balance the weight between front and back. If a bezel is included on
your server, remove it. Then attach the two front brackets to each side of the chassis, then the two rear brackets positioned with just enough space to accommodate
the width of the telco rack. Finish by sliding the chassis into the rack and tightening
the brackets to the rack.

system memory, refer to Chapter 5.
3. If desired, you can install add-on cards to the system. See Chapter 5 for
details on installing PCI add-on cards.
4. Make sure all power and data cables are properly connected and not blocking the chassis airfl ow. See Chapter 5 for details on cable connections. Also,
check the air seals for damage. The air seals are located under the blower
fan and beneath the frame cross section that separates the drive bay area
from the serverboard area of the chassis.
2-7 Checking the Drive Bay Setup
Next, you should check to make sure the hard drives have been properly installed
and all connections have been made.
Checking the Drives
1. For servicing the hard drives, you will need to remove the top chassis cover.
2. If you need to remove or install hard drives, please refer to Chapter 6.
Checking the Airfl ow
1. Airfl ow is provided by four counter-rotating fans. The system component
layout was carefully designed to direct suffi cient cooling airfl ow to the compo-
nents that generate the most heat.
2. Note that all power and data cables have been routed in such a way that they
do not block the airfl ow generated by the fans.
Providing Power
1. The last thing you must do is to provide input power to the system. Plug the
power cord from the power supply unit into a high-quality power strip that offers protection from electrical noise and power surges. It is recommended that
you use an uninterruptible power supply (UPS).
2. Turn on the power switch on the back of the power supply, then depress the
power button on the front chassis control panel.

3-3 Control Panel LEDs
The control panel located on the front of the SC113T chassis has fi ve LEDs. These
LEDs provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Universal Information LED
When this LED blinks red quickly, it indicates a fan failure and when blinking red
slowly a power failure. This LED will be blue when used for UID (Unit Identifi er).
When on continuously it indicates an overheat condition, which may be caused by
cables obstructing the airfl ow in the system or the ambient room temperature being
too warm. Check the routing of the cables and make sure all fans are present and
operating normally. You should also check to make sure that the chassis covers
are installed. Finally, verify that the heatsinks are installed properly (see Chapter
5). This LED will remain fl ashing or on as long as the indicated condition exists.
See the table below for descriptions of the LED states.
