Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SuperServer
7042S-i 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 SuperServer 7042S-i system has come
to you with the processors and memory preinstalled. If your system is not
already fully integrated with a motherboard, processors, system memory
etc., please turn to the chapter or section noted in each step for details on
installing specific components. The 7042S-i may be employed either as a
tower or mounted in a rack as a 4U rackmount chassis. If using it as a
server, please read Server Precautions in the next section and then skip
ahead to Section 2-5.

2-2 Unpacking the SuperServer 7042S-i

You should inspect the box the SuperServer 7042S-i was shipped in and
note if it was damaged in any way. If the server itself shows damage you
should file a damage claim with the carrier who delivered it.

Decide on a suitable location for the SuperServer 7042S-i. It should be
situated in a clean, dust-free area that is well ventilated. Avoid areas
where heat, electrical noise and electromagnetic fields 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 7042S-i 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

SUPERSERVER 7042S-i 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 sufficient airflow and ease in servicing.

Rack Precautions:

- Ensure that the leveling jacks on the bottom of the rack are fully

extended to the floor 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

first, 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 SCSI drives and power supply units 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.

2-4 Installing the SuperServer 7042S-i into a Rack

This section provides information on installing the SuperServer 7042S-i
into a rack unit. (If the 7042S-i has already been mounted into a rack or
if you are using it as a tower, you can skip ahead to Sections 2-5 and 2-

6.) There are a variety of rack units on the market, which may mean the
assembly procedure will differ slightly. The following is a guideline for
installing the 7042S-i into a rack with the rack rails provided in the rack
mount kit. You should also refer to the installation instructions that came
with the rack unit you are using.

Identifying the Sections of the Rack Rails:

The 7042S-i rackmount kit (CSE-PT26 or CSE-PT26B - black) includes two
rack rail assemblies. Each of these assemblies consist of three sections:
an inner fixed chassis rail that secures to the 7042S-i (A), an outer fixed
rack rail that secures directly to the rack itself (B) and a sliding rail guide
sandwiched between the two, which should remain attached to the fixed
rack rail (see Figure 2-1.) The A and B rails must be detached from each
other to install. Two chassis handles are also included with the rail kit.

To remove the fixed chassis rail (A), 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.

Figure 2-1. Identifying the Sections of the Rack Rails

B

A

2-4

SUPERSERVER 7042S-i Manual

Installing the Chassis Rails:

You will need to remove the top cover, the top/left cover and the feet to add
rack rails to the chassis. First, remove the top/left cover by pushing the
release tab in the center of the cover lip while pushing the cover toward
the rear of the chassis (see Figure 2-2). After the cover stops, lift it off.
Each chassis foot has a single screw. Remove the screw then depress
the foot’s locking tab from the inside of the chassis to slide the foot off.
Next, remove the top cover. You should see a release tab at the middle of
the lip. Push this tab toward the chassis edge while pushing the cover
toward the front of the chassis. It should then lift right off. You can now
attach rack rails to the top and bottom (now the sides) of the chassis. First
add the rack handles as shown in Figure 2-3. Then position the fixed
chassis rail sections you just removed along the side of the 7042S-i making
sure the screw holes line up. Note that these two rails are left/right spe­cific. Screw the rail securely to the side of the chassis (see Figure 2-4).
Repeat this procedure for the other rail on the other side of the chassis.
You will also need to attach the rail brackets when installing into a telco
rack.
Locking Tabs: As mentioned, both chassis rails have a locking tab,
which serves two functions. The first is to lock the server into place
when installed and pushed fully into the rack, which is its normal position.
Secondly, 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.

Installing the Rack Rails:

Determine where you want to place the SuperServer 7042S-i in the rack.
(See Rack and Server Precautions in Section 2-3.) Position the fixed 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 both are at the exact same height
and with the rail guides facing inward.

SUPERSERVER 7042S-i Manual

Figure 2-5. Installing the Server into a Rack

Installing the Server into the Rack:

You should now have rails attached to both the chassis and the rack unit.
The next step is to install the server into the rack. Do this by lining up the
rear of the chassis rails with the front of the rack rails. Slide the chassis
rails into the rack rails, keeping the pressure even on both sides (you may
have to depress the locking tabs when inserting).

When the server has been pushed completely into the rack, you should
hear the locking tabs "click". Finish by inserting and tightening the thumb­screws that hold the front of the server to the rack (see Figure 2-5).

Chapter 2: Server Installation

2-7

2-5 Checking the Motherboard Setup

After setting up the the 7042S-i, you will need to open the unit to make
sure the motherboard is properly installed and all the connections have
been made.

1. Accessing the inside of the 7042S-i (see Figure 2-6):

(If rack mounted, first release the retention screws that secure the unit
to the rack. Grasp the two handles on either side and pull the unit
straight out until it locks (you will hear a "click").) Depress the two
buttons on the top (side if tower) of the chassis to release the cover.
There is a large rectangular recess in the middle front of the cover to
help you push the cover away from you until it stops. You can then lift
the cover from the chassis to gain full access to the inside of the server.

2. Check the CPUs (processors):

You should have one or two processors already installed into the
system board. Each processor should have its own heatsink attached.
See Section 5-5 for instructions on processor installation.

3. Verify the proper CPU clock ratio setting:

If the CPU speed is not automatically detected you will need to set the
correct speed with the BIOS Setup utility. See the CPU Speed and Fre­quency Ratio settings in BIOS (Chapter 7) to set the processor speed.

4. Check the system memory:

Your 7042S-i server system may have come with system memory al­ready installed. Make sure all DIMMs are fully seated in their slots. For
details on adding system memory, refer to Section 5-6.

5. Installing add-on cards:

If desired, you can install add-on cards to the system. See Section 5-7
for details on installing PCI add-on cards.

6. Check all cable connections and airflow:

Make sure all power and data cables are properly connected and not
blocking the chassis airflow. See Section 5-3 for details on cable con­nections.

2-6 Checking the Drive Bay Setup

Next, you should check to make sure the peripheral drives have been prop
erly installed and all connections have been made.

1. Accessing the drive bays:

All drives can be accessed from the front of the server. For servicing
the CD-ROM, IDE hard drives and floppy drives, you will need to remove
the top/left chassis cover.

2. Installing components into the 5.25" drive bay:

To install components into the 5.25" drive bays, you must first remove the
top/left chassis cover as described in the previous section. Refer to
Chapter 6 for details.

3. Installing CD-ROM and floppy disk drives:

Refer to Chapter 6 if you need to reinstall a CD-ROM and/or floppy disk
drive to the system.

4. Check the IDE disk drives:

Depending upon your system's configuration, your system may have one
or more drives already installed. If you need to install IDE drives, please
refer to Chapter 6.

5. Check the airflow:

Airflow is provided by one 9-cm cooling fan (a second 9-cm fan is op­tional) and a heavy duty 12-cm exhaust fan. The system component
layout was carefully designed to promote sufficient airflow through the
4U rackmount space. Also note that all power and data cables have

2-10

SUPERSERVER 7042S-i Manual

been routed in such a way that they do not block the airflow generated
by the fans. Keep this in mind when you reroute them after working on
the system.

6. Supplying power to the system:

The last thing you must do is to provide input power to the system. Plug
the power cord from the power supply units 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). Fi­nally, depress the power on button on the front of the chassis.

health of specific components. There are also three buttons on the chassis
control panel.

3-2 Control Panel Buttons

There are three push-button buttons located on the front of the chassis.
These are (in order from left to right) a power on/off button, an NMI (Non­Maskable Interrupt) button and a reset button.

l POWER: This is the main power button, which is used to apply or turn
off the main system power. Turning off system power with this button
removes the main power but keeps standby power supplied to the system.

l NMI: NMI stands for "non-maskable interrupt". Pressing this button

issues a non-maskable interrupt to force the server into a halt state. This is
used for diagnostic purposes, and allows you to perform a memory down­load to determine the cause of a problem.

l RESET: Use the reset button to reboot the system.

3-3 Control Panel LEDs

The control panel located on the front of the SC742S-420 chassis has six
LEDs that 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.

l Power: Indicates external power is being supplied to the system's

power supply unit. This LED should normally be illuminated when the sys­tem is operating.

l HDD: Indicates IDE channel activity. On the SuperServer 7042S-i, this
LED indicates CD-ROM drive activity when flashing.

l NIC1: Indicates network activity on LAN1 when flashing.

l NIC2: Indicates network activity on LAN2 when flashing.

l Overheat: Indicates an overheat condition in the chassis. This may
be caused by cables obstructing the airflow in the system or the ambient
room temperature being too warm. You should also check to make sure
that the chassis covers are installed and that all fans are present and
operating normally. Finally, verify that the heatsinks are installed properly
(see Section 5-5 and Figure 5-4).

l Power Fail: Indicates a power supply fan has failed. The power
supply will continue to operate with a secondary backup fan but will need
to be replaced. Refer to Chapter 6 for details on replacing the power
supply. This LED should be off when the system is operating normally.

3-4 LAN (Ethernet) Port LEDs

The LAN port (located beside the VGA port) has a yellow and a green LED.
See the table below for the functions associated with these LEDs.

System Safety

4-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect
yourself from harm and the SuperServer 7042S-i from damage:

l Be aware of the locations of the power on/off switch on the

chassis as well as the room's emergency power-off switch,
disconnection switch or electrical outlet. If an electrical accident
occurs, you can then quickly remove power from the system.

l Do not work alone when working with high voltage components.

l Power should always be disconnected from the system when

removing or installing main system components, such as the
motherboard, memory modules and the CD-ROM and floppy drives.
When disconnecting power, you should first power down the
system with the operating system and then unplug the power cords
of all the power supply units in the system.

l When working around exposed electrical circuits, another person

who is familiar with the power-off controls should be nearby to
switch off the power if necessary.

l Use only one hand when working with powered-on electrical

equipment. This is to avoid making a complete circuit, which will
cause electrical shock. Use extreme caution when using metal
tools, which can easily damage any electrical components or circuit
boards they come into contact with.

l Do not use mats designed to decrease electrostatic discharge as

protection from electrical shock. Instead, use rubber mats that
have been specifically designed as electrical insulators.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

l Keep the area around the SuperServer 7042S-i clean and free of

clutter.

l The SuperServer 7042S-i weighs approximately 54 lbs (24.2 kg)

when fully loaded. When lifting the system, two people at either
end should lift slowly with their feet spread out to distribute the
weight. Always keep your back straight and lift with your legs.

l Place the chassis top/side cover and any system components that

have been removed away from the system or on a table so that
they won't accidentally be stepped on.

l While working on the system, do not wear loose clothing such as

neckties and unbuttoned shirt sleeves, which can come into contact
with electrical circuits or be pulled into a cooling fan.

l Remove any jewelry or metal objects from your body, which are

excellent metal conductors that can create short circuits and harm
you if they come into contact with printed circuit boards or areas
where power is present.

!

l The power supply power cord must include a grounding plug and

must be plugged into grounded electrical outlets.

l Motherboard Battery: CAUTION - There is a danger of explosion if

the onboard battery is installed backwards, which will reverse its
polarities. The positive side of the battery should be facing up and
the negative side should facing the motherboard. This battery must
be replaced only with the same or an equivalent type recommended
by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.

l CD-ROM Laser: CAUTION - this server may have come equipped

with a CD-ROM drive. To prevent direct exposure to the laser beam
and hazardous radiation exposure, do not open the enclosure or
use the unit in any unconventional way.
