Chapter 2
Rack Installation
This chapter provides advice and instructions for mounting your system in a rack.
2.1 Preparing for Setup
The box in which the system was shipped should include the 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
(~25 inches) and approximately 30 inches of clearance in the back of the rack to allow
sucient space for airow 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
installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a server or other component from
the rack.
• Extend only one server or component at a time - extending two or more simultaneously
may cause the rack to become unstable.
11
Chapter 2 Rack Installation
Precautions
• Review the electrical and general safety precautions in the appendix, "Standardized Safety
Warnings" in this manual.
• 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).
Airow
Equipment should be mounted into a rack so that the amount of airow 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 eect 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.
Supermicro SCLA26 Chassis User's Manual
12
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.

Chapter 2 Rack Installation
2.2 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 dier 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 26.8" and 36.4" deep.
Identifying the Rails
The chassis package includes two rail assemblies. Each assembly consists of three sections:
An inner rail that secures directly to the chassis, an outer rail that secures to the rack, and
a middle rail which extends from the outer rail. These assemblies are specically designed
for the left and right side of the chassis and labeled.
Figure 2-1. Identifying the Outer Rail, Middle Rail and Inner Rail
(Left Rail Assembly Shown)
Note: Both front chassis rails and the rack rails have a locking tab, which serves two functions.
First, it locks the server into place when installed and pushed fully into the rack (its normal
operating position. In addition, these tabs lock the server in place when fully extended from
the rack. This prevents the server from coming completely out of the rack when pulled out
for servicing.
