Chapter 2: System Safety
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. These instructions assume that you are
an experienced technician, familiar 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, le a damage claim with the carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold the chassis. 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 at least two grounded power outlets. The SC835
chassis includes two redundant power supplies which require two grounded out-
lets.
2-3 Preparing for Setup
The SC835 chassis includes a set of rail assemblies, and the mounting brackets
and mounting screws you will need to install the system into a rack. Please read
this manual in its entirety before you begin the installation procedure.

SC835 Chassis Manual
2-2
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC835 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 (not necessary for hot-swappable drives). When discon-
necting power, you should rst 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 specically 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.

2-3
Chapter 2: System Safety
Please handle used batteries carefully. Do not damage the battery in any way;•
a damaged battery may release hazardous materials into the environment. Do
not discard a used battery in the garbage or a public landll. Please comply
with the regulations set up by your local hazardous waste management agency
to dispose of your used battery properly.
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 sufcient 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 specically designed
as electrical insulators.

SC835 Chassis Manual
2-4
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.
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.
