Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your 4042G-72RF4 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 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 specic components. The 4042G-72RF4 may be employed either as
a tower or mounted in a rack as a 4U rackmount chassis. If using it as a tower
unit, please read the Server Precautions in the next section and then skip ahead
to Section 2-5.
2-2 Unpacking the System
You should inspect the box the system was shipped in and note if it was damaged
in any way. If the server itself shows damage you should le a damage claim with
the carrier who delivered it.
Decide on a suitable location for the 4042G-72RF4. It should be situated in a clean,
dust-free area that is well ventilated. Avoid areas where heat, electrical noise and
electromagnetic 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 system was shipped in may include two sets of rail assemblies, two
rail mounting brackets and mounting screws needed for installing the system into
a rack (optional kit). 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.

2-2
A+ SERVER 4042G-72RF4 USER'S MANUAL
Choosing a Setup Location
•Leave enough clearance in front of the system to enable you to open the front
door completely (~25 inches).
•Leave approximately 30 inches of clearance in the back of the system to allow
for sufcient airow and ease in servicing.
•This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and the like).
2-4 Warnings and Precautions
Rack Precautions
•Ensure that the leveling jacks on the bottom of the rack are fully extended to
the 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
simultaneously 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 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 units to cool before touching them.
•Always keep the rack's front door and all server panels and covers closed when
not servicing to maintain proper cooling.

Chapter 2: Server Installation
2-3
Rack Mounting Considerations
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 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.
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 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.
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

2-5 Installing the System into a Rack
This section provides information on installing the system into a rack unit. Rack
installation requires the use of the optional rackmount kit. There are a variety of rack
units on the market, so the procedure may differ slightly. Also refer to the installation
instructions that came with the rack unit you are using.
Identifying the Sections of the Rack Rails
The optional rackmount kit (MCP-290-00059-0B) includes two rack rail assemblies.
Each of these assemblies consist of two sections: an inner xed chassis rail (Figure
2-1) that secures to the chassis, and an outer rack rail that secures directly to the
rack itself. The inner and outer rails must be detached from each other before
installing.
To remove the inner chassis rail, 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. Depress the locking tab to pull the inner rail completely out. Do this for
both assemblies (one for each side).

Installing the Chassis Rails
Remove the top bezel cover and the feet to add rack rails to the chassis. Orient
the chassis in the rackmount position, as in the gure below.
1. Remove the top and right covers by depressing the latch on the rear lip of the
top cover to release it, then push the cover off.
2. Unscrew the four feet from the chassis.
Figure 2-2. Preparing to Install the Chassis Rails
3. Add the rack handles to the front edges of the chassis, as in gure 2-3.
4. Position the inner chassis rail sections along the side of the chassis making
sure the screw holes line up. Note that these two rails are left/right specic.
5. Screw the rail securely to the side of the chassis.
6. Repeat this procedure for the other rail on the other side of the chassis.
If you are mounting the chassis in a Telco rack, also attach the rail brackets.

Installing the Rack Rails
Stability hazard. The rack stabilizing mechanism must be in place, or the rack
must be bolted to the oor before you slide the unit out for servicing. Failure
to stabilize the rack can cause the rack to tip over.
Determine where you want to place the server in the rack. (See Rack and Server
Precautions in Section 2-4.) Position the 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.
