Chapter 2
System Safety
2-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in order given should enable you to have your chassis setup and
operational within a minimal amount of time. This quick set up assumes that you are
an experienced technician, famailiar with common concepts and terminology.
2-2 Warnings and Precautions
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, file a damage claim with carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold that chassis. It should
be situated in a clean, dust-free area that is well venilated. Avoid areas where heat,
electrical noise and eletromagnetic fields are generated.
You will also need it placed near at least one grounded power outlet. When config-
ured, the SC502 chassis includes one power supply.
2-3 Preparing for Setup
The SC502 Chassis bolts directly to a rack and includes the mounting screws you
will need to install the systems into the rack. Please read this manual in its entirety
before you begin the installation procedure.
2-1
SC502 Chassis Manual
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC502 from damage:
•
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.
•
•
Do not work alone when working with high voltage components.
Power should always be disconnected from the system when removing or in-
stalling main system components, such as the serverboard, memory modules
and the DVD-ROM and floppy drives (not necessary for hot swappable drives).
When disconnecting power, you should first power down the system with the
operating system and then unplug the power cords from all the power supply
modules in the system.
•
•
When working around exposed electrical circuits, another person who is fa-
miliar with the power-off controls should be nearby to switch off the power, if
necessary.
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.
•
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.
•
•
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
Serverboard Battery: CAUTION - There is a danger of explosion if the onboard
battery is installed upside down, which will reverse its polarities 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.
2-2
Chapter 2: System Safety
•
DVD-ROM Laser: CAUTION - This server may have come equipped with a
DVD-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 uncon-
ventional way.
2-5 General Safety Precautions
•
•
Keep the area around the chassis clean and free of clutter.
Place the chassis top cover and any system components that have been re-
moved away from the system or on a table so that they won’t accidentally be
stepped on.
•
•
•
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.
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.
After accessing the inside of the system, close the system back up and secure
it to the rack unit with the retention screws after ensuring that all connections
have been made.
2-6 System Safety
Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed
circuit boards. The following measures are generally sufficient to neutralize this
difference before contact is made to protect your equipment from ESD:
•
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.
•
•
Use a grounded wrist strap designed to prevent static discharge.
Keep all components and printed circuit boards (PCBs) in their antistatic bags
until ready for use.
2-3
SC502 Chassis Manual
•
•
•
Touch a grounded metal object before removing any board from its antistatic
bag.
Do not let components or PCBs come into contact with your clothing, which may
retain a charge even if you are wearing a wrist strap.
Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules or contacts.
•
•
When handling chips or modules, avoid touching their pins.
Put the serverboard and peripherals back into their antistatic bags when not
in use.
•
For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

Rack Installation
5-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following these steps in the order given should enable you to have the system
operational in a minimal amount of time.
5-2 Unpacking the System
You should inspect the box the chassis was shipped in, and note if it was damaged
in any way. If the chassis itself shows damage, you should file a damage claim with
the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold your chassis. 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. Be sure to read the Rack and Server Pre-
cautions in the next section.
5-3 Preparing for Setup
The box your chassis was shipped in should include four mounting screws, which
you will need if you intend to install the system into a rack. 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).
Leave approximately 30 inches of clearance in the back of the rack to allow for
sufficient airflow and ease in servicing.
5-1
SC502 Chassis Manual
•
This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and similar environments).
Warnings and Precautions!
!
!
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 simul-
taneously may cause the rack to become unstable.
General Server Precautions
•
Review the electrical and general safety precautions that came with the com-
ponents you are adding to your chassis.
•
•
Determine the placement of each component in the rack.
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 hard drives and power supply modules to cool before touching
them.
Always keep the rack's front door, all panels and all components on the servers
closed when not servicing, in order to maintain proper cooling.
5-2
Chapter 5: Rack Installation
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (TMRA).
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow 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 connec-
tions other than the direct connections to the branch circuit (for example, the use
of power strips, and other devices).
