SC837J Chassis Manual

2-3

•Handle used batteries carefully. Do not damage the battery in any way; a dam-

aged 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.

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.
