Control Panel
Power switches and status LEDs are located on the control panel on the front of the chassis.
Control Panel Features
Feature Description
Power Button The main power switch applies or removes primary power from the power supply to the
server but maintains standby power.
NIC LED Indicates network activity on the LAN when ashing.
Information LED Universal information LED (see table below for details).
BMC Button/
UID LED (Node B)
The BMC reset button resets the BMC rmware when pressed. The unit identication (UID)
button turns on or o󰀨 the blue light function of the Information LED and a blue LED on the
rear of the chassis. These are used to locate the server in large racks and server banks.
Node Label
(Node B)
Label with the name of the node that is connected to the control panel. Labels for nodes
A and C are above their control panel. Labels for nodes B and D are below their control
panel.
Information LED
Color, Status Description
Red, solid An overheat condition has occurred.
Red, blinking at 1 Hz Fan failure, check for an inoperative fan.
Red, blinking at 0.25 Hz Power failure, check for a non-operational power supply
Red, solid, with Power LED blinking green Fault detected
Blue and red, blinking at 10 Hz Recovery mode
Blue, solid UID has been activated locally to locate the server in a
rack environment.
Blue, blinking at 1 Hz UID has been activated using the BMC to locate the
server in a rack environment.
Blue, blinking at 2 Hz BMC is resetting
Blue, blinking at 4 Hz BMC is setting factory defaults

Chapter 2
Server Installation
2.1 Overview
This chapter provides advice and instructions for mounting your system in a server rack.
If your system is not already fully integrated with processors, system memory etc., refer to
Chapter 4 for details on installing those specic components.
Caution: Electrostatic Discharge (ESD) can damage electronic components. To prevent such
damage to PCBs (printed circuit boards), it is important to use a grounded wrist strap, handle
all PCBs by their edges and keep them in anti-static bags when not in use.
2.2 Preparing for Setup
The box in which the system was shipped should include the rackmount hardware needed to
install it into the rack. Please read this section in its entirety before you begin the installation.
Choosing a Setup Location
• The system should be situated in a clean, dust-free area that is well ventilated. Avoid areas
where heat, electrical noise and electromagnetic elds are generated.
• Leave enough clearance in front of the rack so that you can open the front door completely
(approximately 25 inches) and approximately 30 inches of clearance in the back of the
rack to allow su󰀩cient space for airow and access when servicing.
• This product should be installed only in a Restricted Access Location (dedicated equipment
rooms, service closets, etc.).
• This product is not suitable for use with visual display workplace devices according to §2
of the German Ordinance for Work with Visual Display Units.
Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are extended to the oor so that
the full weight of the rack rests on them.
• In single rack installations, stabilizers should be attached to the rack. In multiple rack in-
stallations, the racks should be coupled together.

Chapter 2: Server Installation
17
• Always make sure the rack is stable before extending a server or other component from
the rack.
• You should extend only one server or component at a time - extending two or more simul-
taneously may cause the rack to become unstable.
Server Precautions
• Review the electrical and general safety precautions in Appendix A.
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components at the bottom of the rack rst and then work your
way up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any drives and power supply modules to cool before touching them.
• When not servicing, always keep the front door of the rack and all covers/panels on the
servers closed 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 room's ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (TMRA).
Airow
Equipment should be mounted into a rack so that the amount of air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.

Chapter 2: Server Installation
18
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry
and the e󰀨ect 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.).
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 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.
• Slide rail mounted equipment is not to be used as a shelf or a work space.

2.3 Installing the Rails
This section provides information on installing the chassis into a rack unit with the rails
provided. There are a variety of rack units on the market, which may mean that the assembly
procedure will di󰀨er slightly from the instructions provided. You should also refer to the
installation instructions that came with the rack unit you are using.
Note: This rail will t a rack between 28" and 33.5" deep.
Identifying the Rails
The package includes two rail assemblies. Each is specically designed for the left or right
side of the chassis, and so marked. Each rail consists of two sections: a front section which
secures to the front post of the rack and a rear section which adjusts in length and secures
to the rear post of the rack.
Adjusting the Rail Length
Each rail assembly has a locking screw to adjust the length of the rail to t the depth of your
rack.

Installing the Rails on a Rack
1. Loosen the adjusting screw to allow the rear section to slide in the front section.
2. Push the small hooks on the front section of the rail into the holes on the front post of
the rack and then down, until the spring-loaded pegs snap into the rack holes. Secure
the rail to the rack with screws.
3. Pull out the rear section of the outer rail, adjusting the length until it ts within the posts
of the rack and align the small hooks with the appropriate holes on the rear post of the
rack. Be sure the rail is level, then mount the rear section onto the rack. Secure the rail
with screws.
4. Tighten the adjusting screw.

bottom up.
