SC842 Chassis Manual

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 set up

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.

Place the chassis near a grounded power outlets. The SC842 chassis includes a

power supply which requires a grounded outlet.

2-3 Preparing for Setup

The SC842 chassis includes mounting screws you will need to install the system

into an open (two-post) rack. Optional mounting rails are available for installation

of the chassis into a four-post rack. Part numbers for these mounting rails may

be found on the Supermicro Web site at http://www.supermicro.com/products/

chassis/4U/?chs=842. Please read this manual in its entirety before beginning the

installation procedure.

2-2

SC842 Chassis Manual

2-4 Electrical Safety Precautions

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

and the SC842 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

SC842 Chassis Manual

•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 an

optional 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

unconventional 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.

2-4

SC842 Chassis Manual

•Use a grounded wrist strap designed to prevent electrostatic 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.
