2-1

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 SC836

chassis includes two redundant power supplies which require two grounded out-

lets.

2-3 Preparing for Setup

The SC836 Chassis includes a set of rail assemblies, including mounting brackets

and 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.

SC836 Chassis Manual

2-2

2-4 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm

and the SC836 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 oppy drives (not necessary for hot swappable drives).

When disconnecting 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

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.

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.

SC836 Chassis Manual

2-4

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.

the chassis surface. The SC836 chassis includes permanent standoffs in locations

used by most motherboards. These standoffs accept the rounded Phillips head

screws included in the SC836 accessories packaging.

Some motherboard require additional screws for heatsinks, general components

and/or non-standard security. Optional standoffs are included to these mother-

boards. To use an optional standoff, you must secure a hexagonal post by screwing

it into the necessary spot.

Standoffs Labeling

Standoff locations are labeled on the bottom of the SC836 chassis with the letters:

P, D, and A.

P = Most compatible motherboards have a processor or CPU located here. If neces-

sary, place standoffs here for the CPU's heatsink.

D = Place optional standoffs here if your motherboard requires additional posts to

hold the unit in place.

A = A number of older motherboards have processors or CPUs located in areas

designated "A". Place standoffs here for the CPU's heatsink.
